Pasadena permits include plan check review and may require additional historic preservation review for designated areas.
Pasadena has extensive landmark districts and individually designated historic structures — any exterior alteration or addition inside a landmark district typically requires design review approval before a building permit can be issued, which can add weeks or months to a project's timeline.
The Arroyo Seco and surrounding scenic areas are subject to additional design review and hillside considerations, so projects adjacent to the Arroyo face review layers that projects elsewhere in Pasadena don't encounter.
Pasadena uses the Accela Citizen Access portal at aca-prod.accela.com/COSP (Pasadena's Accela city code is COSP), which is separate from neighboring Accela cities like Ontario and San Bernardino County, so each city is a different login and a different portal.
If the property is inside a landmark district or is an individually designated historic structure, Pasadena requires design review approval before a building permit can be issued — this is a common source of added timeline on additions, exterior changes, and facade work in older parts of the city.
Pasadena permit status is tracked through the Accela Citizen Access portal at aca-prod.accela.com/COSP, which covers residential, commercial, historic preservation, and trade permits issued by the Pasadena Permit Center.
California state law caps Pasadena ADU permit review at 60 days once the application is deemed complete, though projects inside landmark districts can see additional design-review time before the 60-day clock starts.
Pasadena permits follow Accela's type-year-sequence numbering convention with a letter prefix such as B (building), E (electrical), or M (mechanical) followed by a year and a sequence number — the exact format depends on the permit type.
