Contractor vs Builder — Which Do I Need?

An ADU contractor typically performs the physical build under a contract with a separate designer or architect. An ADU builder usually delivers turn-key projects: design + permits + construction under one fixed price. For most first-time owners, a turn-key builder is lower-risk; for owners who already have permitted plans, a contractor-only engagement is cheaper.

Frequently Asked Questions

What is an ADU contractor?

An ADU contractor is a state-licensed construction firm that builds accessory dwelling units — detached backyard homes, garage conversions, attached additions, or basement conversions. ADU contractors handle the physical build (foundation, framing, MEP, finishes) and typically partner with a designer/architect for permit drawings. Many also offer turn-key design-build packages.

How do I find ADU contractors near me?

Aduglossary.com maintains verified ADU contractor directories for 26 US cities (see list below). Each city page lists licensed, insured contractors with completed ADU projects, plus a free quote request form that routes to all featured contractors in that city. You can also check your state contractor license board directly and search "ADU" in the project history.

How much do ADU contractors charge in 2026?

ADU contractors quote $250–$600 per square foot turn-key in 2026, all-in. That ranges from $150,000 for a small garage conversion to $500,000+ for a 1,200 sq ft new-build in coastal California. Construction-only (you supply design + permits) runs $200–$450/sqft. Always get three written fixed-price bids — never accept "time and materials" for an ADU.

Are ADU contractors licensed differently from general contractors?

In most states, no — an ADU contractor holds the same general contractor (B-license in California, equivalent classes elsewhere) license as a home builder. What differs is ADU-specific experience: a contractor who has completed 5+ ADUs in your city understands your local zoning, utility-trenching requirements, and pre-approved plan programs in a way a generalist GC does not.
