Summary
Owners of accessory dwelling units built before January 1, 2020 can apply to delay code enforcement for up to five years under Oakland Municipal Code Article XIV, provided the violations don't threaten health or safety. The Building Official decides case by case, and the program sunsets January 1, 2030.
The purpose of this Article is to allow for a delay of enforcement actions, for a period of no more than five (5) years, for accessory dwelling units built before January 1, 2020, if corrections of violations are not necessary to protect health and safety as per California Government Code, Section 65852.2, subd. (n), and California Health and Safety Code, Section 17980.12. This Article shall remain in effect only until January 1, 2030, and as of that date is repealed. ... A. An owner of an accessory dwelling unit built before January 1, 2020, may submit an application requesting that enforcement be delayed for a period of five (5) years on the grounds that correcting violations is not necessary to protect health and safety. B. If the Building Official determines that correction of the violation(s) is not necessary to protect health and safety, the application shall be granted. C. A delay of enforcement means the City will not penalize the owner for being out of compliance with building standards during the delay period.

Full Breakdown
720 create a narrow amnesty track for legacy, unpermitted ADUs. 12. The Building Official grants the application only after finding correction isn't required for health and safety. A grant means the City won't penalize the owner for being out of compliance with building standards during the delay window, but the owner must use that time to bring the unit into compliance, anything still uncorrected when the delay expires is deemed a public nuisance subject to immediate enforcement. 720(D) bars the delay outright where the ADU has significant structural damage or defects (tilting walls, sagging roofs), lacks a direct exit or an emergency escape window in a sleeping room, has a gas-fired appliance in a bedroom, lacks adequate fire separation between units, or lacks code-compliant smoke alarms and carbon monoxide detectors.
730, an approved delay must be recorded with the Alameda County Recorder, and the owner must inform occupants in writing of the existing violations. 760, the delay applies only to building standards, nuisance and blight violations are enforced on the normal timeline regardless. This Article expires by its own terms on January 1, 2030.
Violations & Fines
There's no independent penalty for using the program correctly: it's an enforcement pause, not an exemption. But if an owner misrepresents conditions to obtain a delay, or the ADU still isn't corrected when the five years (or the January 1, 2030 sunset, whichever comes first) run out, the outstanding violations become a public nuisance subject to immediate enforcement, which can include the City's standard Building Code abatement and civil penalty process under OMC Chapter 1.08.
