Before You Build in New Rochelle, NY: Permit & Rule Checklist (2026)

Pool barriers must meet NYS Residential Code Appendix G: minimum 48-inch fence, self-closing/self-latching gate opening away from the pool with the latch 40+ inches above grade, and pool alarms on pools built or modified after December 14, 2006.

New Rochelle zoning typically limits residential fences to 4 ft in front yards and 6 ft in side and rear yards. Taller fences require a variance from the Zoning Board of Appeals. Corner-lot sight-triangle rules further limit height near intersections.

Retaining walls over 4 feet in height (measured bottom-of-footing to top) require a building permit and engineered plans in New Rochelle. Walls with surcharge loads (driveways, structures above) require engineering regardless of height.

Most residential fences in New Rochelle require a building permit from the Bureau of Buildings. Applications need a site plan showing location, height, and materials. Pool barriers must meet NYS Residential Code Appendix G and are inspected.
