Solar panels visible from public right-of-way on Historic District or individually-Landmarked properties require Cultural Heritage Commission Certificate of Appropriateness.

Frequently Asked Questions
Does Pasadena's Historic District designation prevent me from building an ADU?
No. California state law preempts local ADU restrictions, including Historic District design review for setbacks and size requirements. You can build an ADU on your Historic District property subject to the state standards. However, the Cultural Heritage Commission (CHC) can require that the ADU's exterior design (materials, windows, siding, roof shape) be compatible with your primary dwelling's historic character when visible from the public right-of-way. The CHC cannot prevent your ADU from being built — they can only influence its design within state law limits.
Which Pasadena neighborhoods are in Historic Districts?
Pasadena has 31 Historic Districts covering many of its most desirable neighborhoods. Key districts include Bungalow Heaven (east of Lake Ave between Washington Blvd and Orange Grove), Garfield Heights (south of Foothill Blvd), Madison Heights, Prospect Park (south of Green St), and Orange Grove Boulevard mansions. Use Pasadena's interactive Historic Preservation map at cityofpasadena.net/planning/historic-preservation/ to check whether your property is in a designated district. Individual Landmark designations also exist for 1,000+ specific properties throughout the city.
Does Pasadena have its own utility company for solar and EV charging?
Yes. Pasadena Water and Power (PWP) provides electricity and water service to most of Pasadena — it is a city-owned municipal utility, not Southern California Edison (SCE). This matters for solar interconnection: you submit applications to PWP, not SCE, and PWP has its own net metering rate schedule. Call PWP Solar Services at (626) 744-4005 or visit cityofpasadena.net/publicworks/water-and-power/solar/ before planning your solar project.
What are the ADU opportunities near CalTech or JPL in Pasadena?
The CalTech campus is at 1200 E. California Blvd — surrounding neighborhoods include the Madison Heights, Caltech, and South Orange Grove Historic Districts. These areas have strong rental demand from researchers, graduate students, and JPL employees. ADUs in these neighborhoods typically rent for $1,800–$3,000+/month depending on size and condition. If your property is in a Historic District, coordinate with Pasadena Planning on exterior design compatibility early in your ADU planning process.
How does the Metro L Line (Gold Line) affect parking requirements for my Pasadena ADU?
If your property is within one-half mile of a Metro L Line (Gold Line) station, you are exempt from providing additional parking for your ADU under California Gov Code §66322(a)(1) and §66314(d)(11) (Stats. 2024 Ch. 7 §20). Pasadena's four L Line stations are Memorial Park (Walnut & Raymond), Del Mar (Del Mar Blvd & Raymond), Fillmore (Fillmore St & Raymond), and Sierra Madre Villa (Sierra Madre Blvd & Foothill). Use Google Maps to measure half-mile from the nearest station entrance. Properties within the transit zone can also convert their garage to an ADU without replacing the parking.
Can I rent my Pasadena home on Airbnb during the Rose Bowl or Rose Parade?
Yes, but with the standard Pasadena Home-Sharing restrictions: you must obtain a Home-Sharing Registration ($185/year), the property must be your primary residence, and whole-home rentals are limited to 120 nights per year total. The Rose Bowl Game (January 1) and Tournament of Roses events are among the most in-demand STR periods in Southern California — Pasadena properties near the Rose Bowl and Colorado Blvd parade route command premium rates during these events. Register before listing to avoid fines.
What is the process for building an ADU on a Pasadena Historic District property?
The process for a Historic District ADU in Pasadena has two tracks running in parallel: (1) Standard ADU building permit through Pasadena Planning Building Division — submit through the SmartGov online portal. (2) Certificate of Appropriateness (CoA) from Cultural Heritage Commission for exterior design elements visible from public right-of-way. The CHC review typically takes 4-6 weeks and focuses on material compatibility, window types, siding, and roof form. The CHC cannot impose setback restrictions beyond state law minimums. Both reviews can run concurrently. Contact Pasadena Historic Preservation staff at (626) 744-4023 for pre-application guidance.
