Acton ADU

Headquartered in Campbell, they serve 40+ Bay Area cities including San Francisco. All units are traditionally site-built to California residential standards — the company explicitly does not use prefab or modular construction.

Acton ADU's permitting expertise and established relationships with city departments make them a strong fit for SF homeowners who don't want to navigate that process alone. They offer both pre-designed Build Ready plans and fully custom ADUs. ADU costs in San Francisco typically run higher than elsewhere in the Bay Area — $400–$650 per square foot is common, with total project budgets of $300K–$500K+ for detached units. Full project timelines including SF permitting can stretch 12–18 months. Financing guidance and curated interior packages are included in their service offering.

ADU Builder Minneapolis
ADU Builder Minneapolis is a Twin Cities firm that has made detached backyard ADU construction systematic and predictable for Minneapolis homeowners. The company offers five standardized models ranging from 448 to 624 square feet, each with a defined base price and floor plan, which eliminates much of the guesswork around cost and scope before a shovel hits the ground. Customization options are available through their design studio partnership with Castle Building and Remodeling. Every project starts with a feasibility analysis reviewing municipal zoning codes and lot dimensions, a critical step given that ADU regulations vary significantly across Twin Cities municipalities. The team handles design, permitting, and construction management, and builds throughout Minneapolis, St. Paul, Edina, St. Louis Park, and surrounding suburbs.

ADU Building Systems LLC
ADU Building Systems LLC is a Massachusetts-based ADU contractor offering both factory-built modular and traditional on-site construction options for homeowners across the state. The company positions itself as a hassle-free, full-service provider that manages the entire process from design and permitting through turnkey completion, whether the client wants to house family, generate rental income, or simply add usable space to their property. One of the firm's key differentiators is their modular construction option, where units are built in a climate-controlled facility using premium materials and skilled tradespeople. This approach delivers tighter construction tolerances and reduced weather-related delays compared to traditional site-built ADUs. Every home built through their factory model comes with a 10-year structural warranty backed by one of the largest building suppliers in the Northeast, an unusually strong warranty for the ADU sector. ADU Building Systems LLC serves clients throughout Massachusetts, offering detached ADUs, converted ADUs, and attached ADUs to cover the full range of property configurations.

ADU Design Builders
ADU Design Builders is a family-owned construction firm based in the Tampa Bay area with over 40 years of Florida construction experience and more than 15 years focused specifically on ADU projects in Pinellas County. As a state-certified contractor (License CBC042359), the company brings a level of credentialing and longevity uncommon among ADU specialists, giving homeowners confidence that they are working with an established, accountable business rather than a new entrant capitalizing on ADU demand. The company serves the full range of ADU use cases: multigenerational living arrangements where family members need independent space on the same property, guest suites for hospitality and privacy, and rental income units that add long-term financial value to Tampa Bay properties. Their integrated design and construction service means clients work with one team throughout the project rather than coordinating separately between an architect and a builder. Operating across the Tampa Bay region with deep roots in Pinellas County, ADU Design Builders is particularly well-suited for homeowners on the Gulf Coast side of the metro who want a builder with proven local relationships with inspectors, suppliers, and municipal planning departments. Their decades of Florida construction experience means they understand hurricane-resistant building practices and the specific code requirements that apply to Florida ADU construction.
ADU Hawaii
ADU Hawaii is a Honolulu-based resource and educational organization focused on accessory dwelling units on Oahu, operated by the Hawaii Appleseed Center for Law and Economic Justice. Rather than functioning as a construction firm, the organization provides homeowners with comprehensive guidance on ADU regulations, zoning requirements, and financing options under Hawaii state law. The organization publishes the ADU Homeowners Handbook, a downloadable guide walking single-family homeowners through the full ADU development process on Oahu. They also maintain a network of vetted construction professionals, designers, and permitting specialists that homeowners can connect with for their specific projects. ADU Hawaii serves as a critical education and navigation layer in a state where housing costs are among the highest in the nation. Their work supports both homeowners seeking rental income and families looking to house multiple generations on a single lot. Hawaii ADU lots must be at least 3,000 sq ft, with units ranging from 400 sq ft on smaller lots to 800 sq ft on lots over 5,000 sq ft. Note: ADU Hawaii is a nonprofit resource organization, not a general contractor or design-build firm. Homeowners seeking actual construction should use their vetted professional network.

The company offers city-approved plans and guides homeowners through permitting with the City of Albuquerque. Their construction approach leverages SIPs panels for faster build times, superior energy performance, and reduced long-term operating costs compared to traditional stick-frame methods. The company offers personalized support throughout the development process — from site assessment and design through construction and final inspection. Albuquerque ADU regulations allow detached casitas and attached units on residential lots, and ADU of Albuquerque positions itself as the specialist for homeowners who want a high-performance unit rather than a builder-grade box. The city of Albuquerque also offers free pre-approved casita plans, though ADU of Albuquerque focuses on custom net-zero builds that go beyond these baseline options. The firm serves Albuquerque and surrounding Bernalillo County communities, appealing to homeowners who want a long-term investment in energy efficiency and sustainability alongside the rental income potential of a well-built ADU.

Albuquerque ADU - ADU of Albuquerque
Albuquerque ADU — also known as ADU of Albuquerque — is a dedicated ADU builder in Albuquerque, New Mexico, operated under EsTech Global, focused specifically on sustainable, net-zero ready casita construction. The company offers a streamlined turnkey process: city-approved plans, permit handling, SIPS (Structural Insulated Panel) construction, and solar-ready design all in one package, making it one of the most complete ADU-focused offerings in the Albuquerque market. Their units are built with SIP panels for superior insulation and energy efficiency, triple-pane windows, and passive design principles, making each ADU net-zero ready — meaning the unit can produce as much energy as it consumes when paired with solar. The use of pre-approved city plans reduces permitting delays and simplifies the approval process for homeowners. Note: This entity appears to be the same business as any previously listed "ADU of Albuquerque" entry in the database — the website aduofalbuquerque.com is the same property. Flag as a potential duplicate. Despite the naming difference in the slug, both names refer to the same company and service offering in Albuquerque.

Note: This entry (slug: alpine-adu-denver) and entry ID 5843524b-1f63-447e-943d-abd88f90ebd8 (slug: alpine-adu-denver-denver) appear to represent the same company in the same city — likely a duplicate record that should be reviewed for consolidation.

Note: This entry (slug: alpine-adu-colorado-springs) shares the same company as entries 7295c9ed (alpine-adu-denver) and 5843524b (alpine-adu-denver-denver). All three are city-specific pages for the same Alpine ADU company. The Denver entries may be duplicates of each other and should be reviewed.

Custom designs are tailored to individual lot constraints and HOA requirements, with factory-built prefab options available for faster timelines. This entity (slug: alpine-adu-denver-denver) appears to be a duplicate or near-duplicate of entity 7295c9ed-975c-4d16-a6f3-9164a1fd9110 (slug: alpine-adu-denver), both representing the same company in Denver, CO. The double-city slug strongly suggests this was created as a data artifact. It is flagged here for review and potential consolidation with the primary Alpine ADU Denver record. Service areas span the entire CO Front Range including Boulder, Fort Collins, and Colorado Springs in addition to the Denver metro.
