Questions

Common questions from Redondo Beach homeowners before starting a project.

Start My Project
Can I build an ADU in Redondo Beach?+

Yes. California's ADU laws apply fully in Redondo Beach and most single-family properties can support at least one ADU. We review your specific lot — setbacks, utility connections, existing structures — during the initial consultation.

What ADU options does Redondo Beach allow?+

Redondo Beach allows detached ADUs, attached ADUs, garage conversions, and Junior ADUs. The best type for your property depends on lot size, your goals, and existing structures — we help you figure this out in the feasibility review.

Are there size limits for ADUs in Redondo Beach?+

Under state law, detached ADUs can be up to 1,200 sq ft. Specific parcel constraints may affect the maximum allowable size on your property. We assess your lot and identify the realistic size envelope before design begins.

How long does ADU permitting take in Redondo Beach?+

ADU permit review in Redondo Beach typically runs 6–10 weeks. We prepare complete plan packages — including structural engineering and energy compliance documents — to minimize back-and-forth with the city.

Can I use the ADU as a rental in Redondo Beach?+

Yes. Once the city issues a certificate of occupancy, you can legally rent the unit. Many Redondo Beach homeowners build ADUs specifically for rental income given the area's strong rental demand.

What's a realistic ADU budget in Redondo Beach?+

ADU costs in Redondo Beach generally range from $200,000 to $450,000 depending on size, type, and finish level. We provide a site-specific estimate after evaluating your property — no ballpark numbers.
