Common Questions About Building an ADU in Los Angeles
How do I know which ADU type my property allows?
That’s what the ADU feasibility study answers. It’s a property-level review that pulls parcel data, confirms the zoning classification, identifies the applicable jurisdiction, and assesses existing structures and utility connections. The review determines which ADU types are permitted, what size limits apply, where the unit can be placed, and which permit track applies — all before drawings are commissioned.
Which agency reviews my ADU permit application in Los Angeles?
It depends on where the property sits. Properties inside the City of Los Angeles go through LA DBS. Properties in unincorporated LA County go through LA County DPW. The rules are similar in broad strokes, but review timelines, fee schedules, and application requirements differ — and a submission formatted for the wrong agency gets returned and restarts the review clock. We file directly with both.
How long does ADU plan check take in Los Angeles?
The plan check timeline for a detached new build at LA DBS currently runs three to five months before a permit is issued. The construction itself often takes less time than the permit review. Knowing that going in means your move-in date or rental income start date is built around a realistic timeline rather than an optimistic one.
How can I finance an ADU in Los Angeles?
The two most common paths are a HELOC and PACE financing. A HELOC is a revolving credit line secured by your existing home equity, repaid on a flexible schedule. PACE — Property Assessed Clean Energy financing — is a California-specific option that ties construction costs to your property tax assessment, with repayment through your property tax bill and no separate credit qualification. We are not a lender or financial advisor; the financing decision is yours.
Does a permitted ADU help when I refinance?
Yes. A permitted ADU creates a documented income stream that lenders recognize at refinance, and it supports a rental income projection based on current market conditions in your specific Los Angeles neighborhood. An unpermitted unit is a different position — it cannot be counted toward loan collateral or rental income documentation.
What do I end up with when the ADU is finished?
A closed permit and a certificate of occupancy. The permit record is permanently attached to the property address and is visible to future buyers, lenders, appraisers, and title companies. A completed, inspected ADU is an asset the property carries permanently.
