What an ADU contractor in Los Angeles does

An ADU contractor in Los Angeles is a general building contractor that designs and builds an accessory dwelling unit, a full independent home with its own kitchen and bathroom, on a lot that already has a house, under California's state ADU law. In LA the same contractor also handles the LADBS submission and standard-plan process, and that paperwork is what decides how fast the unit actually gets approved.

Choosing a pro

How to choose the best ADU contractor in Los Angeles

ADU rules are set by state law, so a contractor who knows the timeline and standards saves you months.

  1. 1

    Check they know the 60-day approval rule

    California ADU law requires the city to approve or deny a complete ADU application within 60 days, ministerially and with no public hearing. A contractor who prepares a complete submission the first time keeps that clock short.

  2. 2

    Design to the by-right minimums

    State law requires local agencies to allow an ADU of at least 800 square feet with 4-foot side and rear setbacks and up to 16 feet in height. That sets the baseline a Los Angeles design should be able to hit without a variance.

  3. 3

    Confirm the general building license

    A detached ADU is a complete structure touching multiple trades, so it needs a Class B General Building contractor. Verify the classification and that the license is active.

  4. 4

    Ask about the LADBS standard-plan path

    The Los Angeles Department of Building and Safety runs an ADU Standard Plan Program that pre-approves designs to speed permitting. A local ADU builder should know whether a standard plan fits your lot.
