Build an ADU in Los Angeles and Start Earning Rental Income This Year
Your property is sitting on an opportunity. A professionally built accessory dwelling unit (ADU) adds $50,000–$150,000+ to your property value and generates monthly rental income — all with LA's most experienced ADU builder.
LA's ADU Opportunity Is Real — But Only With the Right Builder
The City of Los Angeles has made ADU construction easier than ever. But the process still requires navigating permits, setback rules, utility connections, and inspections. An unlicensed contractor can leave you with an unpermitted unit you can't rent, can't sell, and can't finance. That's not an asset — that's a liability.
