ADU vs Tiny House: Zoning, Cost, and Resale Value [2026]

Affiliate disclosure: Some links in this article may earn us a commission at no extra cost to you. We only recommend products and services we've thoroughly researched.

Quick Answer: ADUs (Accessory Dwelling Units) and tiny houses serve similar purposes — compact, affordable living — but they differ dramatically in zoning acceptance, total cost, and long-term resale value. ADUs are permanent structures that follow standard building codes, typically cost $150,000–$400,000, and can boost your property value by 20–30%. Tiny houses on wheels cost $30,000–$150,000 but face major zoning restrictions in most municipalities and add zero value to your property appraisal. If you're thinking long-term investment, the ADU wins. If you want mobility and lower upfront cost, the tiny house has its place. This guide breaks down every angle so you can make the right call.

ADU vs Tiny House at a Glance: The Comparison Table

Before we get into the details, here's the side-by-side breakdown that covers the major decision points:

That table tells most of the story. But the details matter — especially when you're making a six-figure decision. Let's break each factor down.

What Exactly Is an ADU? What Exactly Is a Tiny House?

These terms get thrown around interchangeably online. They shouldn't be. The distinction matters for your wallet, your legal standing, and your property value.

Accessory Dwelling Units (ADUs)

An ADU is a secondary residential unit built on a single-family lot. It's a permanent structure — meaning it sits on a foundation, connects to utilities, and meets all local building codes. ADUs come in several forms:

• Detached ADU: A standalone structure in the backyard, separate from the main house
• Attached ADU: An addition built onto the existing home with its own entrance
• Garage conversion: Transforming an existing garage into a living space
• Basement conversion: Converting below-grade space into a separate dwelling
• Internal ADU: Carving out a portion of the main home as an independent unit

The key characteristic: an ADU is real property. It's part of your lot, assessed by the county, and included in your home's appraised value. When you sell, the buyer gets the ADU. When the appraiser visits, they count it.

California alone added over 25,000 ADU permits in 2023, and that number has continued climbing through 2025 and into 2026. Oregon, Washington, Minnesota, and Vermont have all passed statewide ADU legislation. The trend is clear — ADUs are becoming a standard part of American housing.

For the full regulatory landscape, see our ADU Regulations by State guide.

Tiny Houses

A tiny house is generally defined as a dwelling under 400 square feet. But the critical distinction is between tiny houses on wheels (THOWs) and tiny houses on foundations.

Tiny houses on wheels are built on a trailer chassis. Legally, they're classified as personal property — similar to an RV or a camper. They're not real estate. They don't get recorded on a deed. They don't show up on a property appraisal.

Tiny houses on foundations are, functionally, small ADUs. If you build a 300-square-foot structure on a permanent foundation with proper permits, it's an ADU in the eyes of your municipality. The zoning rules, building codes, and appraisal treatment are the same as any other ADU.

This guide focuses primarily on the more common comparison: a permitted ADU vs. a tiny house on wheels (THOW). That's where the real differences — and the real decision — live.

Zoning and Legal Status: Where You Can Actually Build

This is the single biggest differentiator between ADUs and tiny houses. And it's the one that trips up most buyers.

ADU Zoning in 2026

The ADU zoning landscape has shifted dramatically over the past five years. Here's where things stand:

States with comprehensive ADU legislation:

• California: AB 2221 and SB 9 have made ADUs legal on virtually every single-family lot statewide. Local jurisdictions cannot impose minimum lot sizes, owner-occupancy requirements, or parking mandates for ADUs. California remains the national leader — see our breakdown of ADU Zoning Laws: California AB 2221 & SB 9.
• Oregon: HB 2001 requires all cities with populations over 2,500 to allow ADUs in residential zones. Portland has been particularly aggressive, with some of the fastest ADU permitting timelines in the country.
• Washington: SB 5235 mandates ADU allowances in most residential zones statewide, with local governments limited in the restrictions they can impose.
• Vermont: Act 47 requires all municipalities to allow at least two ADUs per single-family lot.
• Minnesota: Statewide ADU reform passed in 2023, requiring cities over 10,000 to allow ADUs.
• Connecticut, Montana, and New York have all enacted or are implementing ADU-friendly legislation as of 2025–2026.

The trend is unmistakable. According to the American Planning Association, over 40 states now have some form of ADU-enabling legislation at the state or local level. Five years ago, that number was under 15.

What this means practically: if you own a single-family home in a major metro area, there's a strong chance you can build an ADU. The permit process involves submitting plans, meeting building codes, and waiting 4–12 weeks for approval in most jurisdictions. It's bureaucratic, yes. But it's a known process with clear rules.

Tiny House Zoning in 2026

Tiny houses on wheels exist in a legal gray area that hasn't resolved nearly as cleanly as ADU zoning.

The core problem: Most municipal zoning codes don't have a category for THOWs. They're not houses (no foundation). They're not RVs (not built to RVIA standards, in many cases). They're not mobile homes (different construction standards and size). So where do they fit?

The answer, in most places: they don't.

• Most cities prohibit full-time occupancy of an RV or THOW on residential property. You can park it, but you can't legally live in it.
• Some cities have created THOW-specific ordinances. Fresno, California was an early adopter. A handful of cities in Oregon, Texas, and Colorado have followed. But these remain exceptions, not the rule.
• Tiny house communities and villages offer a workaround — dedicated developments where THOWs are welcome. These exist in perhaps 200–300 locations nationwide, but they require renting a lot and following community rules.
• Rural and unincorporated areas often have minimal zoning enforcement, making them the default option for many tiny house owners. This works until it doesn't — a neighbor complaint or a code enforcement visit can force relocation.

A 2025 survey by the National Association of Home Builders found that only 8% of U.S. municipalities have formal zoning provisions that allow tiny houses on wheels as permanent residences. Compare that to ADUs, where the number is north of 60% in metro areas.

The bottom line: if legal clarity and long-term security matter to you, the ADU has a massive advantage. You'll have a permit, a certificate of occupancy, and legal standing. With a THOW, you might be one zoning complaint away from having to move.

Permits and Building Codes

ADU permits follow standard residential construction pathways. You'll need:

• Site plan and architectural drawings
• Structural engineering (in most cases)
• Building permit
• Electrical, plumbing, and mechanical permits
• Inspections at each construction phase
• Certificate of occupancy upon completion

The cost of permits and fees ranges from $5,000 to $30,000 depending on your jurisdiction. California cities tend to be on the higher end; smaller municipalities charge less. Some cities — Los Angeles, San Jose, Portland — have created streamlined ADU permit processes with pre-approved plans that can cut approval times to 2–4 weeks.

Tiny house permits are a different story. Because most jurisdictions don't have a THOW category, the permit path is often unclear. Some options:

• Build to ANSI 119.5 (the park model RV standard) and register as an RV
• Build to NFPA 1192 and certify through an independent inspector
• Work with a certified THOW builder who handles compliance
• Simply build and hope for the best (not recommended)

The lack of a clear permit pathway is one of the biggest practical challenges with tiny houses. It affects insurance, financing, and — critically — your ability to sell.

Cost Breakdown: What You'll Actually Spend

Let's get specific about money. The sticker price difference between an ADU and a tiny house is significant, but the full picture is more nuanced than "tiny house = cheap, ADU = expensive."

ADU Costs in 2026

The total cost of an ADU depends heavily on type, size, location, and finishes. Here's what the numbers look like nationally:

By type:

• Garage conversion: $80,000–$200,000
• Basement conversion: $50,000–$150,000
• Attached ADU (addition): $150,000–$350,000
• Detached new construction: $180,000–$450,000
• Prefab/modular ADU: $120,000–$300,000 (installed)

By size (detached new construction):

• 400 sq ft (studio/1-bed): $120,000–$220,000
• 600 sq ft (1-bed/1-bath): $180,000–$300,000
• 800 sq ft (2-bed/1-bath): $240,000–$380,000
• 1,000+ sq ft (2-bed/2-bath): $300,000–$450,000+

Regional variation matters enormously. Building a 600-square-foot ADU in Los Angeles runs $250,000–$350,000. The same unit in Austin might cost $150,000–$220,000. In a rural area of the Midwest, you might get it done for $120,000–$170,000.

For a full regional breakdown, check our ADU Cost by State guide.

Hidden costs to budget for:

• Permits and impact fees: $5,000–$30,000
• Site preparation and grading: $3,000–$15,000
• Utility connections (sewer, water, electrical): $5,000–$25,000
• Landscaping restoration: $2,000–$10,000
• Architectural and engineering fees: $5,000–$20,000
• Furnishing (if renting): $5,000–$15,000

Total all-in cost for a typical 600 sq ft detached ADU: $200,000–$350,000 in most metro markets.

Tiny House Costs in 2026

Tiny houses on wheels have a wider cost range because of the variety of build approaches:

By build method:

• DIY build: $15,000–$60,000 (materials only; your labor is "free")
• Shell only (from a builder): $25,000–$50,000
• Turnkey from a builder: $50,000–$150,000
• High-end/luxury THOW: $100,000–$180,000
• Used tiny house: $20,000–$80,000

By size:

• 100–200 sq ft (micro): $30,000–$60,000
• 200–300 sq ft (standard): $50,000–$100,000
• 300–400 sq ft (large THOW): $80,000–$150,000

Additional costs:

• Trailer/chassis: $4,000–$10,000 (often included in builder price)
• Land lease or lot rental: $300–$800/month (ongoing)
• Towing and setup: $1,000–$5,000
• Off-grid systems (solar, composting toilet, water tank): $5,000–$20,000
• Insurance: $1,000–$3,000/year (specialty policies)
• Storage when not in use: $100–$300/month

Total first-year cost for a turnkey tiny house: $60,000–$170,000 including setup and first year of lot rental.

The Real Cost Comparison

Here's where it gets interesting. The upfront cost of a tiny house is clearly lower. But consider the total cost of ownership over 10 years:

ADU (600 sq ft, $250,000 build):

• Construction: $250,000
• Annual property tax increase: ~$2,500/year × 10 = $25,000
• Maintenance: ~$2,000/year × 10 = $20,000
• Insurance increase: ~$500/year × 10 = $5,000
• 10-year total: ~$300,000
• Value added to property: $150,000–$250,000
• Net cost after value recovery: $50,000–$150,000

Tiny House (300 sq ft, $90,000 build):

• Purchase: $90,000
• Lot rental: $500/month × 120 = $60,000
• Insurance: $2,000/year × 10 = $20,000
• Maintenance and repairs: $1,500/year × 10 = $15,000
• Depreciation over 10 years: -$40,000 to -$60,000
• 10-year total: ~$185,000
• Value added to property: $0
• Resale value after 10 years: $30,000–$50,000
• Net cost after resale: $135,000–$155,000

The tiny house costs less upfront. But after 10 years, the ADU is the better financial investment by a significant margin — especially if you're generating rental income from it. An ADU renting at $1,800/month produces $216,000 in gross rental income over 10 years. Even after expenses, that can cover most or all of the build cost.

Resale Value: The Make-or-Break Factor

If you're thinking about this purely as a financial decision, resale value is where ADUs dominate. It's not even close.

How ADUs Affect Property Value

According to a 2024 study by the National Association of Realtors, homes with a permitted ADU sell for 20–35% more than comparable homes without one. In hot markets like the San Francisco Bay Area, Los Angeles, Portland, and Seattle, that premium can be even higher.

Let's put real numbers on it. Say your primary home is worth $600,000. Add a well-built, permitted ADU and your property could appraise at $720,000–$810,000. That's $120,000–$210,000 in added value.

The ROI depends on what you spent to build:

• If you spent $200,000 on the ADU and it adds $180,000 in value, that's a 90% cost recovery — plus you had rental income the whole time.
• If you spent $150,000 on a garage conversion and it adds $120,000 in value, that's 80% recovery on a much lower investment.
• In premium markets, some homeowners see more than 100% ROI — meaning the ADU adds more value than it cost to build.

Key factors that maximize ADU resale value:

• Full kitchen and bathroom (not a kitchenette)
• Separate entrance with privacy from the main home
• Permitted and code-compliant (unpermitted ADUs are a liability, not an asset)
• Quality finishes comparable to the main home
• Adequate parking (even if not required by code)
• Good natural light and outdoor space

For deeper analysis, see our guide on How ADUs Increase Property Value: ROI Analysis.

How Tiny Houses Affect Property Value

They don't.

A tiny house on wheels is personal property. It's not attached to the land. It's not recorded on the deed. When an appraiser evaluates your property, the THOW sitting in the backyard is invisible. It's like a car parked in the driveway — it has value, but it's the owner's value, not the property's value.

Worse, tiny houses depreciate. Like RVs and vehicles, THOWs lose value over time. A $90,000 tiny house might be worth $50,000–$60,000 after five years and $30,000–$45,000 after ten. The rate of depreciation depends on the builder, materials, maintenance, and market demand, but the trajectory is always down.

There are exceptions. A high-quality THOW from a respected builder (like Tumbleweed, Escape, or New Frontier) in excellent condition may hold value better. Custom builds with premium materials and clever design can command strong resale prices in the used tiny house market. But you're selling it separately from your property — it's a personal property transaction, not a real estate transaction.

The financial reality:

• An ADU is an appreciating asset tied to appreciating real estate
• A tiny house on wheels is a depreciating asset with no connection to your property value
• Over a 15–20 year horizon, this difference can amount to $200,000+ in wealth building

What Lenders and Appraisers Think

This matters because it affects your ability to leverage the investment.

ADUs: Most lenders now recognize ADU rental income in mortgage qualification. Fannie Mae updated its guidelines in 2021 to allow ADU rental income to be counted, and Freddie Mac followed. This means building an ADU can actually help you qualify for a refinance or future home purchase. Appraisers use the income approach, the cost approach, or comparable sales to value the ADU — all standard real estate methodology.

Tiny houses: Lenders don't consider THOWs in property valuations. Period. You can't get a home equity loan against a tiny house. You can't refinance based on having one. The financing options for purchasing a tiny house are limited to personal loans (high interest rates, short terms), RV loans (if the THOW is RVIA-certified), or specialty tiny house lenders (a small but growing niche).

Rental Income Potential

Both ADUs and tiny houses can generate rental income. But the ease, legality, and profitability differ substantially.

Renting an ADU

ADU rental is straightforward in most jurisdictions. Once you have your certificate of occupancy, you can rent to a long-term tenant or, in many areas, list on short-term rental platforms like Airbnb and VRBO.

Typical ADU rental income by market (long-term, 2026):

• San Francisco Bay Area: $2,200–$3,500/month
• Los Angeles: $1,800–$3,000/month
• Portland: $1,400–$2,200/month
• Seattle: $1,800–$2,800/month
• Austin: $1,200–$2,000/month
• Denver: $1,400–$2,200/month
• Nashville: $1,200–$1,800/month
• Midwest metros: $800–$1,500/month

Short-term rental income can be significantly higher — 30–50% more than long-term rates in tourist-friendly markets. But check local STR regulations. Many cities have tightened rules around Airbnb-style rentals, requiring permits, limiting the number of rental days, or mandating owner-occupancy.

An ADU generating $2,000/month in rent produces $24,000/year in gross income. After property management (if applicable), maintenance, insurance, and taxes, you might net $16,000–$20,000 annually. Over 10 years, that's $160,000–$200,000 in net rental income — often enough to cover the entire ADU construction cost.

For more on ADU rental strategies, see our guide on Renting Out Your ADU.

Renting a Tiny House

Renting out a tiny house on wheels is more complicated:

• Long-term rental: Possible but legally murky. If the THOW isn't in a zone that permits it as a dwelling, your tenant has no legal protections — and neither do you.
• Short-term/vacation rental: This is where tiny houses shine. The novelty factor makes THOWs popular on Airbnb, especially in scenic or rural locations. A well-positioned tiny house can generate $100–$250/night in tourist areas.
• Legal requirements: Even for short-term rental, you'll need to navigate local regulations. Some rural areas are more permissive; urban areas are typically more restrictive.

The earning potential is real but less predictable and less scalable than ADU rentals. And the legal risk is higher.

Lifestyle and Practical Considerations

Not every decision is purely financial. Here's how ADUs and tiny houses compare on livability and lifestyle.

Space and Comfort

ADUs range from 400 to 1,200+ square feet. A well-designed 600-square-foot ADU includes a full kitchen, bathroom, bedroom, and living area. It feels like a small apartment — because that's essentially what it is. You get standard ceiling heights (8–9 feet), full-size appliances, and room to move.

Tiny houses on wheels typically max out at 400 square feet, with many in the 200–300 range. Living in one requires commitment to minimalism. Loft sleeping areas with limited headroom, compact kitchens, and multipurpose furniture are standard. It works for some people — particularly singles, couples, and those who spend most of their time outdoors. But it's a significant lifestyle adjustment.

Mobility vs. Permanence

The tiny house's biggest advantage is mobility. Don't like your location? Hitch up and move. Want to spend summers in Colorado and winters in Arizona? A THOW makes that possible (assuming you have places to park in both locations).

ADUs are permanent. They're part of your property. This is a disadvantage if you value mobility, but an advantage in every other way — legal status, property value, financing, insurance, and tenant appeal.

Sustainability and Off-Grid Living

Tiny houses have a genuine edge in sustainability. Their small footprint means less material, less energy consumption, and easier integration with off-grid systems. Solar panels, composting toilets, rainwater collection, and propane-free heating are all common in the THOW world.

ADUs can also be built to high sustainability standards — many builders offer net-zero or near-net-zero options. But because ADUs connect to municipal utilities by default, the off-grid angle is less inherent.

Who Each Option Is Best For

An ADU is the right choice if you:

• Own your home and plan to stay for 5+ years
• Want to build long-term property value
• Need legal, code-compliant housing for a family member or tenant
• Plan to generate rental income
• Want standard financing and insurance options
• Value full-size living spaces with standard amenities

A tiny house on wheels is the right choice if you:

• Prioritize mobility and flexibility over stability
• Want the lowest possible upfront cost
• Are comfortable with legal ambiguity in your housing situation
• Embrace a minimalist lifestyle and don't need much space
• Want off-grid capability
• Plan to use it as a vacation property or seasonal dwelling rather than a permanent residence

Financing Your ADU or Tiny House

How you pay for these two options differs significantly — and the financing landscape strongly favors ADUs.

ADU Financing Options

ADUs benefit from being real property. That opens up the full range of real estate financing:

• Home equity loan or HELOC: Borrow against your existing home equity. Rates in 2026 typically range from 6.5–9% depending on your credit and equity position. This is the most common ADU financing method.
• Cash-out refinance: Replace your existing mortgage with a larger one and use the difference to fund the ADU. Works well if your current rate is below market.
• Construction loan: A short-term loan that converts to a permanent mortgage upon completion. Useful for larger ADU projects.
• ADU-specific loan programs: Companies like RenoFi, Figure, and several credit unions now offer loans specifically designed for ADU construction. Some California municipalities offer low-interest ADU loans or grants.
• FHA 203(k) loan: If you're buying a home that needs renovation, you can include ADU construction costs in the purchase loan.
• Fannie Mae HomeStyle Renovation loan: Similar to 203(k) but with conventional loan terms.

For the full breakdown, see our ADU Financing Options guide.

Tiny House Financing Options

Financing a THOW is harder because lenders don't treat it as real estate:

• Personal loan: Unsecured, higher interest rates (10–18%), shorter terms (3–7 years). Available from most banks and credit unions.
• RV loan: If your THOW is RVIA-certified, you may qualify for an RV loan with better terms (5–8%, 10–15 year terms). Not all tiny houses qualify.
• Specialty tiny house lenders: A few lenders focus specifically on tiny house financing. Terms vary but are generally between personal loans and RV loans.
• Builder financing: Some tiny house builders offer payment plans or financing partnerships.
• Savings/cash: Many tiny house buyers pay cash, especially for DIY builds.

The interest rate differential alone is significant. Borrowing $150,000 for an ADU at 7% over 20 years costs about $139,000 in interest. Borrowing $80,000 for a tiny house at 12% over 7 years costs about $37,000 in interest — lower total interest, but much higher monthly payments ($1,280/month vs. $1,163/month for the ADU loan).

Insurance Differences

ADU Insurance

A permitted ADU is typically covered as an additional structure under your homeowner's insurance policy, or you can get a separate dwelling policy. Coverage includes:

• Structure/dwelling coverage
• Liability coverage
• Loss of rental income coverage (if rented)
• Contents coverage (for your belongings or tenant's, depending on policy)

Adding an ADU to your homeowner's policy typically increases your premium by $300–$800/year, depending on the ADU's value, size, and whether it's rented.

Tiny House Insurance

Insuring a THOW requires specialty coverage because standard homeowner's policies won't cover it:

• RV insurance: Available if the THOW is RVIA-certified and registered as an RV. Covers collision, liability, and contents.
• Specialty tiny house insurance: Companies like Strategic Insurance Agency and Foremost offer THOW-specific policies. Annual premiums run $1,000–$3,000.
• Liability gaps: If your THOW is in a legal gray area (parked where zoning doesn't permit full-time occupancy), insurance claims can get complicated.

The insurance gap isn't just about cost — it's about coverage reliability. ADU claims are standard homeowner's insurance territory. THOW claims can involve disputes about the dwelling's legal status, location, and classification.

Common Mistakes to Avoid

ADU Mistakes

1. Building without permits. An unpermitted ADU is a liability, not an asset. It won't be counted in appraisals, it can trigger fines, and it can kill a home sale. Always build with permits.
2. Underestimating costs. Budget 15–20% above your contractor's estimate for contingencies. ADU projects routinely run over budget due to site conditions, permit delays, and scope changes.
3. Ignoring setback and height requirements. Every jurisdiction has setback rules (how far the ADU must be from property lines) and height limits. Know these before you design.
4. Skipping the utility assessment. Connecting to sewer, water, and electrical can be straightforward or extremely expensive depending on your site. Get this assessed early.
5. Choosing the wrong builder. Not all contractors have ADU experience. Ask for ADU-specific references and check their track record. See our guide on How to Choose an ADU Builder.

Tiny House Mistakes

1. Assuming you can park it anywhere. The single biggest tiny house mistake. Research zoning in your target location before you buy or build.
2. Overbuilding for the trailer. THOWs have weight limits dictated by the trailer and your towing vehicle. Exceeding these limits creates safety and legal problems.
3. Ignoring resale reality. A custom THOW that perfectly fits your lifestyle may be very hard to sell. Unusual layouts, extreme customization, and niche features narrow your buyer pool.
4. Not planning for lot access. Where will you park? Do you have legal access to utilities? Is there a lease or lot rental agreement in place? Answer these before you build.
5. Skipping RVIA or third-party certification. Certification improves financing options, insurance access, and resale value. It's worth the extra cost.

Frequently Asked Questions

Can a tiny house on wheels be considered an ADU?

In most jurisdictions, no. An ADU must be a permanent structure on a foundation that meets local building codes. A tiny house on wheels is classified as personal property — similar to an RV. However, a tiny house built on a permanent foundation and permitted through the normal building process would be classified as an ADU. The distinction is the foundation and the permit, not the size.

Which adds more value to my property — an ADU or a tiny house?

The ADU, by a wide margin. A permitted ADU can increase your property value by 20–35%, with the investment recovering 80–100% of construction costs at resale. A tiny house on wheels adds zero value to your property because it's classified as personal property, not real property. It's not included in appraisals and isn't recorded on your deed.

Is it cheaper to live in a tiny house than an ADU?

In terms of upfront cost, yes — a tiny house typically costs $30,000–$150,000 compared to $150,000–$400,000 for an ADU. But ongoing costs can narrow the gap. Tiny house owners often pay lot rent ($300–$800/month), face higher insurance costs, and deal with depreciation. ADU owners may pay higher property taxes but build equity and can offset costs with rental income.

Can I get a mortgage for a tiny house?

Not a traditional mortgage. Tiny houses on wheels aren't real property, so they don't qualify for conventional mortgages, FHA loans, or VA loans. Your options are personal loans, RV loans (if RVIA-certified), or specialty tiny house lenders. ADUs, by contrast, can be financed through home equity loans, HELOCs, construction loans, and ADU-specific lending programs.

What happens to my tiny house when I sell my property?

Your tiny house goes with you — or you sell it separately. Since a THOW is personal property, it's not part of the real estate transaction. You'd need to either take it with you or negotiate a separate sale with the buyer. An ADU, on the other hand, transfers with the property automatically since it's a permanent part of the real estate.

The Verdict: Which Should You Choose?

There's no universal answer, but there is a clear pattern.

Choose an ADU if your primary goals are building long-term wealth, generating reliable rental income, providing legal housing for family or tenants, and maximizing your property's value. The higher upfront cost is an investment — one that pays returns through appreciation, rental income, and equity building. If you own your home and plan to stay for five or more years, the ADU is almost always the smarter financial move.

Choose a tiny house if your priorities are mobility, minimal upfront investment, off-grid living, or a transitional housing solution. Tiny houses work well as vacation properties, temporary housing between moves, or lifestyle experiments. They're not great long-term financial investments, but they can be excellent lifestyle investments for the right person.

The hybrid approach also works. Some homeowners build a permitted ADU for rental income and property value, then keep a tiny house on wheels for personal use — a weekend getaway, a mobile office, or a guest house that can travel. You get the financial benefits of the ADU and the flexibility of the THOW.

Whatever you choose, do the legal homework first. Zoning, permits, and building codes aren't exciting, but they're the foundation (literally, in the case of ADUs) of a sound housing decision. A beautiful, well-built structure that violates local codes is a headache waiting to happen.
