Retaining Wall Permit Requirements in Floral Park, NY
CORRECTION: AHJ is the Incorporated Village of Floral Park Building Department (One Pool & Garage Road, 516-326-6319), NOT Nassau County. Under New York law every village administers and enforces the NYS Uniform Code locally, so the Village handles permits inside village limits. The applicable construction code is the 2020 Residential Code of New York State (RCNYS), part of the statewide Uniform Code, plus the 2020 Energy Conservation Construction Code (ECCCNYS). Permits are submitted through the Village's iWorq online portal. The official Village domain is floralparkny.gov (fronted by a CloudFlare WAF that hard-blocks automated clients); fpvillage.org is a separate legacy presence. Department hours, a published fee schedule, and a department email were not obtainable from the live source and are left null rather than fabricated.
