Everything you need to know about building an ADU in Los Angeles

ADU Overview

There are 3 different types of ADUs: detached, attached, and converted space.

Detached ADUs are new structures built separately from any existing structure or home on the property. An attached ADU is much like building an addition on your home but an attached ADU will have a kitchen/ette, bathroom, and a separate entrance.

A converted space ADU occurs when you convert an existing space, such as a garage, a basement, or an attic, into a usable separate dwelling unit.

ADU Requirements

Every ADU must have:

  • A kitchen or kitchenette (a small kitchen or part of a room equipped as a kitchen)
  • A bathroom with a shower
  • A bedroom or studio space for a bed
  • 5 ft lot line setbacks
  • 10 ft setbacks from other structures (in place for fire safety measures)
  • Code, energy-efficient windows (T24), and utility compliance for the state of CA and your city specifically

About SB9

Senate Bill 9 — the California Housing Opportunity and More Efficiency (HOME) Act — streamlines the process for a homeowner to create a duplex or subdivide an existing lot. Any new housing created as a result of this bill must meet a specific list of qualifications that protects historic districts, preserves environmental quality and the look of communities, and prevents tenants from being displaced. This legislation will enable homeowners to create intergenerational wealth, and provide access to more rental and ownership options for working families who would otherwise be priced out of neighborhoods.

We read the bill so you don’t have to. Here are few details we think you should know.
All CA cities must:

  • Allow ADUs up to 800 sq. ft. (most CA cities allow ADUs up to 1,000 or even 1,2000 sq. ft.)
  • Waive parking requirements if within .5 miles of public transit
  • Respond to your plan submission within 60 days (faster than other projects)
