Full Breakdown
Chapter 8.72 covers small residential rooftop solar energy systems no larger than 10 kilowatts AC or 30 kilowatts thermal, installed on single- or duplex-family homes. The Director of Community Development must maintain an administrative, nondiscretionary expedited review process with a standard checklist implementing the state Solar Rights Act (AB 2188). Once an application is deemed complete, City staff must issue a nondiscretionary building permit within a reasonable time, accept electronic submittal and signatures in lieu of paper forms, and perform only one inspection unless the system fails it.
Violations & Fines
Installing a rooftop solar system without the required nondiscretionary building permit is a code violation; the Director may require a discretionary use permit only upon written findings of a specific, adverse health or safety impact.
