Premium ADU Design & Build in Santa Monica
Santa Monica homeowners are generating $3,000–$4,500/month in rental income with custom ADUs. We handle every step — design, permits, and construction — in one of LA's most demanding permit environments.
Why Santa Monica Homeowners Are Building ADUs
Santa Monica sits at the center of one of Southern California's most desirable rental markets. Beach access, top-rated dining, major tech and media employers, and easy freeway and transit access drive consistent demand from high-income renters — making ADU rental income here particularly strong.
Studio and one-bedroom ADUs in Santa Monica typically rent for $2,800–$4,200/month. For a homeowner investing $180,000–$280,000 in a detached ADU, that represents a 12–18% gross annual yield — among the strongest ADU returns available anywhere in Greater Los Angeles.
- Among the highest ADU rental rates in all of Greater Los Angeles
- Strong year-round demand from tech, healthcare, and entertainment professionals
- Proximity to LAX and the Westside job corridor drives premium rents
- High underlying property values amplify the asset-value impact of an ADU
- Excellent walk score and Big Blue Bus / Expo Line access attract car-free tenants
- California ADU law and Santa Monica code allow ADUs on most single-family lots

We've built ADUs across Santa Monica and the surrounding area — navigating local zoning, permit processes, and site conditions that generalist contractors don't know.
Licensed & Insured General Contractor
ADU Build LA holds an active California General Contractor (B) license with CSLB and carries full general liability and workers' compensation insurance. Every subcontractor on your project is licensed, insured, and verified before they set foot on your property.
200+ ADUs Built Across LA County
We've completed over 200 ADU projects — garage conversions, detached new construction, Junior ADUs, and attached units — across every major LA-area city. That depth of experience means we've seen every site condition, every permit challenge, and every construction scenario.
15+ Years of ADU Experience
Since before the 2020 ADU law reforms, we've been building accessory dwelling units in Los Angeles. We've navigated every iteration of state ADU law, local zoning changes, and city permit process updates — institutional knowledge that directly accelerates your project.
Transparent, Fixed-Price Contracts
We don't use time-and-materials billing or open-ended design fees. Every project starts with a detailed all-inclusive fixed price covering design, engineering, permitting, and construction. What we quote is what you pay — no surprise change orders, no scope creep billing.
In-House Permit Management
Our team has submitted hundreds of permit applications across LADBS, Santa Monica, Pasadena, Glendale, Culver City, and other LA-area jurisdictions. We know each city's plan check process, common correction triggers, and expedite options — reducing wait time and managing every step for you.
