West Hollywood Wants Your ADU Built.
West Hollywood has rewritten its ADU rules repeatedly to keep pace with state law, most recently through a 2025 update to Municipal Code Section 19.36.310. The result is one of the friendlier rulebooks in Los Angeles County: ADU applications are approved ministerially, with no discretionary review or public hearing, and the city must approve or deny a complete application within 60 days or it is deemed approved. The ordinance also charges no city impact fees on any ADU or JADU.
The city goes further with a Pre-Approved ADU Plan Program: detached ADUs using a plan on the city's pre-approved list must be approved or denied within 30 days. That is precisely the lane a factory-built, repeatable design is made for. Curious what fits on your property? Check your lot in about a minute.
Single-Family Lots: One ADU Plus A JADU.
On a lot with a single-family home, West Hollywood allows one ADU and one junior ADU (JADU). A detached, new-construction backyard ADU of up to 800 square feet qualifies for the simplest building-permit-only path, with 4 foot side and rear setbacks. Larger units go through a ministerial ADU permit: up to 850 square feet for a studio or one-bedroom and up to 1,200 square feet for two or more bedrooms, and no city standard can force an ADU below 800 square feet. JADUs are capped at 500 square feet inside the existing home.
Detached ADUs may rise to 18 feet, plus two more feet (to 20) to match the primary home's roof pitch; attached ADUs can reach 25 feet or the zone's height limit, whichever is lower, up to two stories. Front setbacks are 10 feet in R-1 and R-2 zones, and total floor area ratio in the R1-A, R1-B, and R1-C districts is capped at 0.5. Best of all for WeHo's tight lots: no off-street parking is required, and if you demolish a garage or carport to make room, those spaces do not have to be replaced.
Multifamily Lots Get Real Capacity.
Most of West Hollywood is multifamily, and the ordinance treats those properties seriously. Owners can convert non-livable space in an existing building, think storage rooms, boiler rooms, attics, basements, or garages, into ADUs equal to 25 percent of the existing unit count, with at least one conversion always allowed. On top of that, a lot with an existing multifamily building can add up to eight detached ADUs (not exceeding the number of primary units on the lot), and a lot with a proposed multifamily building can add two, each with 4 foot side and rear setbacks.
For apartment owners, that is a path to meaningful new rental income on land you already own, with ministerial approval and no parking requirement. Abodu works with multifamily and portfolio owners on exactly these projects. See how it works on our multifamily page, or hear from owners on our testimonials page.
WeHo Quirks Worth Knowing.
West Hollywood layers a few objective design standards on top of state law. Exterior lighting must be limited to downlights, and no ADU window or door may have a direct line of sight into a neighbor's window or door unless it is screened by fencing, landscaping, or privacy glass. Detached ADUs need a 6 foot separation from other structures on the lot. Rooftop decks are prohibited on ADUs, except in the R-3 and R-4 districts where one may be sought through a development permit. On properties listed on the California Register of Historical Resources, the ADU must be placed so it is not visible from the public right-of-way.
A few more essentials: ADUs built since 2020 have no owner-occupancy requirement (JADUs do), a deed restriction is recorded before the certificate of occupancy, and under recent state law the city has moved to allow qualifying ADUs to be sold separately as condominiums, per the city's zone text amendment project page. Statewide rules are summarized by the California Department of Housing and Community Development.
What It Actually Costs.
Custom site-built ADUs in California routinely exceed $250,000 before change orders, and that number only moves in one direction once excavation surprises and contractor markups appear. Abodu takes a different approach: transparent published pricing: homes from $234,800 plus a published installation price, an expected all-in from $298,800 that covers design, permits, factory build, delivery, and installation. Clear allowances, no change orders, no surprises.
Because your Abodu is built in a factory while your West Hollywood permits move through the city's ministerial 60 day (or 30 day pre-approved) review, the timeline compresses dramatically compared to stick-built construction. See how the process works.
