ADU Laws in La Mesa: Overview

California enacted multiple new laws between 2017 to 2022 that reduce regulatory barriers around constructing ADUs and junior ADUs (JADUs):

  • Allow ADUs on virtually all residential lots
  • Limit ADU size and setbacks
  • Streamline approval and permitting
  • Cap or waive certain development fees

La Mesa updated its zoning code regarding ADUs in 2020 to comply with California Government Code Sections 65852.2. The new standards appear in Chapter 24.05 of the La Mesa Municipal Code. Let’s break down key elements of La Mesa’s ADU building regulations for lots with existing or proposed single-family homes. We also summarize the ADU allowance and rules for multifamily properties.

ADU Allowances for Multifamily Properties

Beyond single-family homes, ADU laws in La Mesa allow:

  • Up to 2 detached ADUs per existing multifamily building

Attached and detached ADUs present lucrative rental opportunities, while internal conversions better utilize unused floor areas.
