Special Considerations
HOA Rules
HOA approval often required first. Many Thousand Oaks neighborhoods have HOAs with solar guidelines stricter than city codes. Submit plans early to avoid delays.
Zoning
Check zoning for solar allowances. Rules on lot coverage, height, and setbacks apply. Roof-mounted usually easier than ground-mount.
Historic Properties
Historic districts may need extra review. If your home is in a designated area, visible installations could require design review for aesthetics.
