Castro Valley FAQ

Can my HOA require specific panel colors?

Only if it does not reduce efficiency by more than 10 percent or add more than 1,000 dollars in cost. All-black panels are typically acceptable, but restrictive tile-matching rules often fail this test.

What if my HOA delays my solar application?

Under Civil Code 714, failure to respond within 45 days constitutes approval. Document your submittal date and proceed if no decision is issued.

Hayward FAQ

Can my HOA deny my solar panels?

No, outright denial violates Civil Code 714; only minor aesthetic restrictions that do not impair performance over 10% are enforceable.

What if my HOA ignores my application?

Failure to respond within 45 days results in automatic approval under Civil Code 714.
