Mountain View 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.
