Zoning & HOA Considerations

Zoning

Siding replacement rarely triggers zoning review outside historic districts. Historic districts (Charleston, Savannah, Boston, Santa Fe, and many others) have strict material and color requirements. Hurricane-prone coastal areas may require wind-rated cladding with product approval.

HOA Communities

If you live in an HOA community: hOAs commonly regulate siding material, color, and style, often more strictly than city code. Architectural Review Committee (ARC) approval is typically required before any exterior cladding change. Submit to HOA before applying for a city permit.
