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).
Do I need a permit to run a business from my home in Los Angeles?
Yes. A Home Occupation Permit ($163 fee) is required for any business operated from a residence. Restrictions apply: no customers on-site, no employees who aren't residents, no exterior signs, and business use must be incidental to residential use. Violations can result in $250–$1,000 fines per day.
Can I do short-term rentals (Airbnb) in Los Angeles?
Yes, with restrictions. You must register with the city ($89/year) and the property must be your primary residence. Whole-home rentals are limited to 120 nights per year (an Extended Home Sharing Permit allows unlimited nights with additional requirements).

What is the front yard setback in an R1 zone in Los Angeles?
The standard front yard setback in an R1 zone is 20 feet from the front property line. However, if the average front setback of structures on the same block face is greater than 20 feet, your setback may need to match the block average. Fences over 3.5 feet also require permits in front yards. Always verify with ZIMAS (zimas.lacity.org) for your specific parcel.
Are solar panels required on new homes in Los Angeles?
Yes. California's Title 24 Energy Code (effective January 1, 2020 for single-family, updated 2023) requires solar photovoltaic systems on all new low-rise residential construction. Battery storage requirements also apply to many new builds under the 2023 standards. New homes in LA must comply with these state requirements.
