Fairfield FAQ
Can my HOA block my Fairfield rooftop solar install?
No. California Civil Code §714 voids HOA rules that significantly raise solar costs (more than ~$1,000 typically) or reduce efficiency by more than 10%. HOAs can impose reasonable aesthetic conditions that don't trigger those thresholds, but cannot prohibit panels outright.
Does Fairfield require a permit for residential battery storage like a Tesla Powerwall?
Yes. Energy storage systems are reviewed under CEC Article 706 and CFC §1207 separately from PV panels and do not qualify for SolarAPP+ instant approval. Expect plan review of 2-6 weeks plus a separate building/electrical inspection.
Vallejo FAQ
Do I need a permit for solar panels?
Yes, a building and electrical permit is required. Many jurisdictions offer expedited or over-the-counter permits for standard residential rooftop solar systems.
Can my neighbor build something that shades my solar panels?
Many states have solar access laws that protect existing solar installations. Check state law and Vallejo zoning code for solar easement protections.
