San Jose FAQ
How long does a San Jose solar permit take?
Through SolarAPP+, qualifying residential rooftop PV systems typically get an instant automated permit issued within minutes to hours. Non-eligible projects (large, ground-mount, complex) go through normal plan check and usually clear within a few weeks.
Does San Jose charge solar plan-check fees?
San Jose charges a flat permit fee but cannot charge fees beyond reasonable cost-of-service under California Government Code §65850.5. SolarAPP+ projects benefit from streamlined fees because automated review eliminates most plan-check labor.
Can my HOA block solar panels?
No. California Civil Code §714 (Solar Rights Act) prohibits HOAs from unreasonably restricting residential solar installations, including in San Jose. HOAs can require minor aesthetic placement choices but cannot impose costs that significantly reduce performance or efficiency.
Sunnyvale FAQ
Does SolarAPP+ work for non-standard roof types?
SolarAPP+ approves only configurations matching its pre-approved templates: standard rafter spacing, common module brands, and code-compliant racking. Tile, slate, or atypical structures still require traditional plan-check at the County permit center.
Can my homeowners association block a SolarAPP+ install?
California's Solar Rights Act and Civil Code §714 prevent HOAs from imposing significant cost or efficiency penalties. HOAs may require minor architectural placement adjustments but cannot effectively prohibit solar installation.
