Introduction
Pasadena is one of the more complex cities for ADU design in Los Angeles County. With 16 historic landmark districts and strict design standards, your ADU plans need to be prepared by a team that understands Pasadena’s specific requirements. Uni Construction has experience designing ADUs that satisfy both state law and Pasadena’s objective design criteria.
Why Pasadena Homeowners Build ADUs
Premium rental rates: Pasadena’s desirability near Old Town, Caltech, and the Rose Bowl supports rental rates of $2,000–$3,500/month for a well-designed ADU.
Historic district protections (limited): Under AB 1061 (effective 2026), cities can only block ministerial ADU processing if your specific property is individually listed as a historic landmark — being in a historic district alone is no longer enough.
High property values: ADUs in Pasadena can add $150K–$300K+ to property value due to the city’s premium real estate market.
Transit accessibility: Gold Line stations eliminate parking requirements for ADUs within half a mile of stops.
Local Permitting
Pasadena has its own ADU ordinance with objective design standards that include material, window proportion, and roof pitch requirements. Properties in Historic Preservation Overlay Zones (HPOZs) may face additional review — but state law limits how this can block your project. We handle all Pasadena-specific compliance.
Neighborhoods We Serve
We design ADUs throughout Pasadena including South Pasadena border, Bungalow Heaven, Madison Heights, San Rafael, Linda Vista, Hastings Ranch, and neighborhoods near Caltech and PCC.
