Local planning notes
Pasadena provides online ADU submittal services and city guidance for ADUs and JADUs.
Historic districts and individually designated properties can have additional visibility and design considerations.
The city states that its earlier standard plans expired December 31, 2025; as of 2026, the displayed plans are limited to qualifying Eaton Fire red-tagged properties while future updates are evaluated.
Housing and design context
Pasadena includes Craftsman neighborhoods, historic districts, postwar homes, carriage-house conditions, and properties with alleys or mature landscapes. A successful ADU plan should respect the existing home while solving privacy, driveway, tree, utility, and outdoor-space relationships.
How ADLA approaches it
We check the current city program rather than assuming an older standard plan remains available. Custom planning may be the appropriate route when the property, household, or architectural context needs a site-specific response.
Relevant services
Yes. Pasadena publishes electronic permitting services for ADU plan submission and also offers current planning and permit resources on its website.
The city states that plans from the earlier program expired at the end of 2025 and are currently limited to qualifying Eaton Fire red-tagged properties. Check the official city page for new plan availability.
Historic districts and designated properties can add siting, visibility, and design conditions. Confirm the property status early and coordinate with the city’s historic-preservation guidance.
