Start your free analysis →An Accessory Dwelling Unit (ADU) is one of the smartest investment property moves a San Diego homeowner can make in 2026. With updated state laws and the City of San Diego's Bonus ADU Program, qualifying lots can now build multiple ADUs — generating rental income, increasing property value, and creating space for family. Below, we break down the four areas every San Diego homeowner should understand before starting an income-producing ADU project.
Converting a 1- or 2-car garage into a livable ADU is the fastest, lowest-cost path to rental income in San Diego. Most projects fall between $80,000 and $180,000 depending on plumbing, electrical and finish level. Garage conversions in San Diego are especially popular in North Park and La Jolla due to lot sizes and rental demand — and they consistently deliver some of the strongest ADU ROI in San Diego.
San Diego's permit process for garage conversions is streamlined when the existing structure is sound and meets setback requirements. Our team handles everything — from Title 24 energy reports to final inspection — with a focus on maximizing your property value.

Cost drivers include site conditions, utility connections, foundation type, and design complexity. Hillside lots in La Jolla often cost more due to engineering, while flat lots in Chula Vista or El Cajon are more affordable.
