How long does it take to build an ADU in Los Angeles?

Most ADU projects in Los Angeles run between 6 and 12 months from initial design through certificate of occupancy. Permitting typically adds 2 to 4 months depending on plan check volume at LADBS or Beverly Hills. Garage conversions and JADUs can move faster since they don't require new foundations.

Do I need permits to build an ADU?

Yes. All ADUs require building permits in California. Unpermitted units create serious problems when you sell or refinance. We handle the entire permit process, including architectural plans, Title 24 energy compliance, and all required inspections through final sign-off.

Can I rent out my ADU?

Yes. A properly permitted ADU can be rented as a long-term unit. California law also allows JADUs on owner-occupied properties. Short-term rental regulations vary by city, so we recommend confirming the rules in your specific area before listing on platforms like Airbnb or VRBO.

Does adding an ADU increase my property taxes?

Building an ADU typically triggers a reassessment of the new structure only. Your main home's assessed value remains protected under Proposition 13. The tax increase is generally modest relative to the rental income and overall property value gain an ADU provides regulations vary by city, so we recommend confirming the rules in your specific area before.

How many ADUs can I have on my property?

California law now allows most single-family lots to build one ADU and one JADU simultaneously. Multifamily properties may qualify for additional units. The specifics depend on your zoning, lot size, and existing structures, which we assess during your free site evaluation.

Detached ADU

A fully independent structure on your existing lot, with a separate entrance, full kitchen, bathroom, laundry, and living space. Detached ADUs offer the most privacy for both households and typically command the highest rental rates. Best for properties with open rear or side yard space.

Garage Conversion ADU

An underused garage is often the fastest path to a permitted ADU. We handle insulation, HVAC, electrical upgrades, plumbing rough-in, and finished interiors to convert storage space into a livable, legally permitted unit.

Attached ADU

An addition connected to your primary residence that functions as a self-contained unit with its own entrance. A practical choice when lot size limits a detached build but you still want a fully independent living space.

Junior ADU (JADU)

Up to 500 square feet carved out of your home's existing footprint, often a converted bedroom, basement area, or attached garage portion. JADUs require an efficiency kitchen but share or connect to the main home's systems, keeping construction costs lower.
