Acton ADU

What Acton ADU does

Acton ADU, legally Acton Construction, Inc., is a Campbell, California-based design-build firm founded by Stan Acton in 1990 that specializes exclusively in accessory dwelling units (ADUs). The company pivoted from general residential remodeling to ADU specialization in 2017 to capture demand created by California housing legislation, and rebranded as Acton ADU. Its core offering is an end-to-end ADU delivery model — feasibility analysis, architectural design, structural engineering, Title 24 energy compliance, permitting, site-built construction, and post-completion warranty — managed under a single accountable team via a three-phase Feasibility, Pre-Construction, and Build & Warranty process with an online project portal.

The product portfolio centers on the Build Ready ADU line, which comprises more than 100 pre-designed, pre-engineered model variations organized into an Investor Series (cost-efficient, standardized configurations such as 888 sq. ft., 2-bedroom/2-bath layouts) and a Signature Series (premium finishes, architectural detailing, vaulted ceilings). Build Ready models are site-built to California residential standards rather than prefabricated, and are supported by an online property-fit assessment tool and an interactive design configurator (design.actonadu.com). A separate Custom ADU offering delivers fully personalized designs for properties unsuited to the standard library, and Home Remodeling and Financing Assistance are retained as supporting services.

Acton ADU operates a direct-to-consumer go-to-market model targeting California homeowners, generating one-time project revenue per ADU build via website-driven lead capture, free property feasibility checks, free estimate requests, and a consultative sales process. The company currently serves the Bay Area (Silicon Valley, Peninsula, San Jose) and, as of April 2026, Los Angeles County across the Westside, Central LA, San Gabriel Valley, and San Fernando Valley — covering 100+ California cities. The business is founder-owned, privately held, has no disclosed institutional funding, and employs 11-50 people.
