Room Addition Permit Requirements in Lee County, FL
AHJ resolution: Lee County DCD is the building permit authority for UNINCORPORATED Lee County, which includes the dominant residential portion of ZIP 33912 (Gateway / Six Mile Cypress / Daniels Parkway corridor). Confirmed verbatim on the official leegov.com/dcd page: 'Lee County Community Development is responsible for overseeing planning, zoning, development services, permitting, plan review, inspections, & code enforcement for unincorporated areas of Lee County' and 'Please contact the incorporated areas of Bonita Springs, Cape Coral, Estero, Fort Myers, Fort Myers Beach or Sanibel for similar services within those jurisdictions.' The incorporated municipalities of Cape Coral, Fort Myers, Bonita Springs, Estero, Fort Myers Beach, and Sanibel run their own permitting departments and are excluded from county jurisdiction. Phone 239-533-8585, fax 239-485-8344, office 1500 Monroe St., Fort Myers, FL 33901, hours 9am-4pm Mon-Fri — all taken directly from the official .gov DCD contacts block. Other official numbers: automated inspection scheduling and flood questions 239-533-8948 (flood), general permitting 239-533-8585. Online permitting via the eConnect (Accela) portal. Property-level jurisdiction (city vs. county) and flood zone should be verified per parcel via LeeGIS Data Explorer (https://gisexplorer.leegov.com/) or the Lee County Property Appraiser; the City of Fort Myers in-limits test is whether the parcel number contains a 'P'. Hazards: hurricane high-wind design, wind-borne-debris (opening protection) requirements, and FEMA flood-zone / floodplain-management compliance are central to SW Florida residential permitting; many 33912 parcels are in flood zones along Six Mile Cypress Slough.

When you need a Addition permit in Lee County
Home additions almost always require a building permit because they change the structure, footprint, and often the electrical, plumbing, and mechanical systems. Sealed architectural plans are typically required, and additions over 500 sq ft commonly trigger zoning review for setback and lot-coverage compliance (IRC R105.1).
