Hillsborough County does not enforce a pool fence ordinance - barrier rules come from the New Hampshire State Building Code under RSA 155-A. New Hampshire has adopted the International Residential Code (IRC) with state amendments. Residential pool barriers follow IRC Appendix AG (Section AG105), which requires a barrier at least 48 inches high with no openings allowing a 4-inch sphere to pass and self-closing, self-latching gates. Permits are issued by each city or town building department.
