The Honest Answer: It Depends On Who Builds It.
There are two ways to add an ADU in California. A custom site-built project starts with an architect, moves through bids and subcontractors, and routinely exceeds $250,000 before the change orders that traditional construction is famous for. A fixed-price factory-built home flips the model: the price is set in your agreement before construction starts, and the building is finished in a factory while your site is prepared.
Because Abodu publishes real prices, we can show you the actual numbers most builders keep behind a quote form: the home, the installation, and the total, separately and together.

What's Quoted Separately.
A handful of items sit outside the all-in number, and every one is quoted upfront in your proposal: a flat $6,000 boundary survey, foundation staking, and certification package; water, sewer, and power trenching beyond 50 feet; craning beyond 100 feet; demolition or tree removal; unique site engineering; and sales tax.
Permits, Fees, And Taxes.
Permits and plan check are included in your installation price, and Abodu prepares and submits everything for you. Two pieces of state law also work in your favor: ADUs under 750 square feet are exempt from local impact fees, and cities must approve or deny a complete application within 60 days. At 750 square feet and larger (Abodu Two+, Three, and Three+), cities may add development impact fees; we quote your city’s exact figure in your proposal, before you sign anything. Local rules still shape your project, which is why we publish 44 city-by-city guides and a plain-English summary of every California ADU law.
