ADU Plans in Pasadena
Pasadena has some of the most active building and ADU development in the San Gabriel Valley – and some of the most detailed plan check requirements. Pasadena reviews projects in certain areas through its design review process, and its historic preservation overlay zones add layers that most designers don’t anticipate. We’ve submitted dozens of projects to Pasadena’s planning and building departments and know exactly what their examiners expect in a submittal.
Why Pasadena Clients Work With Us
Pasadena’s specific plan areas, hillside development standards, and landmark districts all require designers who understand the local review process – not just the base building code. We’ve navigated Pasadena’s discretionary review boards, addressed their specific Title 24 and green building requirements, and handled plan check corrections that other firms couldn’t resolve.
With 1,500+ projects completed across Los Angeles County since 2015, we bring a depth of experience that most firms can’t match. We don’t just know the California building code – we know how Pasadena’s building department applies it.
Pasadena enforces strict design guidelines in its historic districts and has local ADU standards layered on top of state law.
