City of LA standard plans

Two models the City has already approved.

Model 1 and Model 2 are approved plans in the City of Los Angeles Standard Plan Program. A pre-approved plan skips the full plan check, which can save weeks or months on your permit if your home is in the City of LA. Outside the City, the plans go through that city's normal plan check.

LA ADU rules in plain English

What you can build in the City of Los Angeles.

The basics for a single-family lot in the City of LA. Every lot is different, so we confirm each of these for your address before we price anything.

Size

Up to 1,200 sq ft

A detached ADU can be up to 1,200 sq ft. Your lot's floor area and coverage limits can make it smaller, but they can't stop an 800 sq ft ADU with 4 ft side and rear setbacks.

LAMC 12.22 A.33(d)(1)
Setbacks

4 ft from the side and rear

The City can't require more than 4 ft from the side and rear lot lines. Converting an existing garage or accessory building needs no new setback.

LAMC 12.22 A.33(c)(8)
Height

Set by your zone

The City has no single ADU height. Your zone and height district set it. State law guarantees at least 16 ft for a detached ADU, and 18 ft near major transit.

LAMC 12.22 A.33(c)(1); Gov. Code 66321(b)(4)
Parking

Often none

No space is needed within a half-mile walk of transit, near a car-share spot, in a historic district, or for a conversion. Otherwise it's one space, and tandem on the driveway counts. Tearing down a garage for the ADU doesn't mean replacing its parking.

LAMC 12.22 A.33(c)(12)
Living on site

Not required

You don't have to live on the property to build or rent an ADU. A junior ADU inside the house only requires you to live there if it shares a bathroom with the house.

Gov. Code 66333(b)
Renting and selling

Rent it, don't sell it separately

An ADU can be rented, but generally not as a short-term rental of 30 days or less. In the City of LA it can't be sold apart from the main house.

Gov. Code 66323(e); LAMC 12.22 A.33(h)(3)
Changing on January 1, 2027

SB 1117 limits the impact fee on an ADU over 750 sq ft to the area above 750 sq ft, in proportion to the main house, for up to two ADUs on a lot. ADUs of 750 sq ft or less still pay no impact fee.

AB 956 lets you build two new detached ADUs on a single-family lot through the state's approval path. On that path a city can cap each one at 800 sq ft.

How it works

From your backyard to move-in.

Step 1

Pick a model

Choose a model and finishes online, or book a free consultation to talk it through.

Step 2

Site assessment

We visit your lot, check utilities, access and the City's rules, and give you one all-in price before you sign.

Step 3

Design and permits

We finish the plans and run the permit with LADBS or your city from submittal to approval.

Step 4

Build and move in

We build on site and manage the job through final inspection and your certificate of occupancy.

Typical timeline: 8 to 12 months from start to finish. About 1 month of design, 2 to 4 months of permits and 3 to 5 months of construction, shorter for our pre-approved models in the City of LA. Your lot and the city's review times can move it.

From an LA client

We had an outstanding experience working with Buildoly on our ground-up ADU construction project here in LA. From start to finish, their team demonstrated exceptional expertise & patience with our municipality, particularly with our city's unique & complex permitting process. They were true partners throughout, consistently blocking & tackling any issues that came up during permitting, ensuring our project stayed on track. Their professionalism & dedication made a navigating the permit process much smoother, and we couldn't be happier with the results. Highly recommend Buildoly to anyone looking for a reliable & skilled architects specializing in ADUs.
