Frequently Asked Questions
Can I build an ADU in my backyard in Los Angeles?
Yes. California state law requires LA to permit ADUs by-right on all residential lots. You can build a detached ADU up to 1,200 sqft in your backyard, plus a Junior ADU (JADU) up to 500 sqft within your existing home. No owner-occupancy requirement applies. Permits are processed ministerially (no discretionary review) within 60 days.
What is the difference between an ADU and a JADU in Los Angeles?
An ADU (Accessory Dwelling Unit) is a fully independent unit with its own kitchen, bathroom, and entrance — it can be detached or attached to the main home, up to 1,200 sqft. A JADU (Junior ADU) must be within the existing footprint of the single-family home or garage, is limited to 500 sqft, must share the property owner's address, and requires only an efficiency kitchen (can share a bathroom with main home).
