ADU Rescue

Accessory Dwelling Units (ADUs) created without permits should be permitted, including any necessary upgrades as soon as possible, to avoid the risks of unpermitted construction. However, this may not always be feasible right away. 

ADU Rescue is a program that allows qualifying owners to ask for an enforcement extension of up to five (5) years on an ADU created without permits. One of the primary goals of this program is to avoid displacing occupants of these ADUs until permits can be aquired, while ensuring they do not present a threat to health and safety. See 7-0-21 ADU Enforcement Extension Request for the full program policy.

How do I qualify for Enforcement Extension?

Your ADU may be eligible for delayed enforcement if both of the following are true:

• It was constructed during one of the following time periods:

  • Before October 14, 2021.
  • January 1, 2023 - Before January 4, 2024.

  • January 1, 2025 - Before January 8, 2026.

• It is not considered substandard under Section 17920.3 of the Health and Safety Code as determined by a habitability inspection conducted by a person licensed by the California Contractors State License Board or a licensed design professional like an architect or engineer. This inspection must contain, at minimum, a review of the structure for compliance with housing standards pursuant to the California Health and Safety Code, from a licensed professional.
