Frequently Asked Questions — ADU Contractor Santa Monica

How much does an ADU cost in Santa Monica in 2026?

A garage conversion ADU in Santa Monica costs $90,000–$155,000 in 2026 — higher than the City of LA average due to Santa Monica’s own permit fees and Westside labor rates. A detached new-construction ADU runs $155,000–$310,000. ADU rental income of $2,400–$3,500/month makes Santa Monica one of the strongest ROI ADU markets in California.

Does Santa Monica’s rent control apply to new ADUs?

Santa Monica’s Rent Control Ordinance is one of the most complex in California. New ADUs built after specific dates are generally exempt from rent control, but the interaction of your property’s existing rental units, the ADU’s configuration, and recent ordinance changes can create nuanced situations. APLA walks every Santa Monica ADU client through the rent control question before design — and recommends consulting a Santa Monica real estate attorney for a definitive opinion.
