FAQ

Long Beach ADU questions.

Ask about your lot

Can I use a pre-approved ADU plan in Long Beach?

Yes. Long Beach runs a Pre-Approved ADU Program (PAADU). Those plans can be approved over the counter. We check whether a pre-approved plan fits your lot or a custom design works better.

Can I convert my garage to an ADU in Long Beach?

Usually, yes. Garage conversions are one of the most common ADUs we build in Long Beach. Your feasibility report checks the structure, utilities and what the city will require.

Can I build an ADU over my garage in Long Beach?

Often, yes. Our Wrigley project is a two-story build with a 4-car garage and an 800 sf ADU above it. Height and setbacks depend on your lot.
