Building in Miami.
In Miami-Dade, an addition is governed by your municipality's zoning code (lot coverage, setbacks, height, and sometimes design review) and by the Florida Building Code, including High-Velocity Hurricane Zone requirements for structure, roofing, windows and doors. Second-story additions require an engineer's review of the existing foundation and walls. We review your survey and existing conditions first, then set a schedule around permits, structural work and long-lead items. Clients also call us to take over and finish additions a previous contractor left incomplete; we start by documenting existing work, open permits and inspections.
