Timeline & Phases
What influences sequencing from early study through closeout.
Four separate things decide the timeline
State baseline reviewed September 26, 2026. Local procedures, exceptions and parcel conditions still apply.
The statutory review clock
After an ADU application is submitted, the local agency must say in writing within 15 business days whether it is complete, and generally approve or deny a complete application within 60 days (Gov. Code § 66317). The clock measures agency review of a complete application — not design, corrections, utility work or construction.
If the agency finds the application incomplete or issues corrections, the time the applicant's team spends revising drawings and resubmitting is outside the agency's clock. Complete, coordinated drawings are the part of the schedule the owner's team controls most.
Water, sewer, electric and gas connections are reviewed and scheduled by the utility or agency that owns each system, sometimes on separate applications. Their timing is not set by the ADU review clock; ask each provider what it needs and when.
Once a permit is issued, duration depends on scope, site conditions, material lead times, inspections and any correction notices in the field. No general duration applies to every property; a schedule should be built from the actual scope.
Yes. California requires a local agency to approve or deny a complete ADU permit application within 60 days (Gov. Code §66317). The clock starts only when the application is complete; correction rounds, utility work and inspections are outside it.
Can monthly permit counts predict my approval time?
No. Census and city reports record authorizations issued, not how long each took. RSA shows those counts for context and asks you to enter your own week estimates per stage, labelled as your scenario.
It can affect concrete pours, roofing and excavation. The planning timeline flags days with rain chance of 40%+, wind of 20 mph+ or heat of 90°F+ as questions to ask your builder — not as a guaranteed work window.
