What the Florida Building Code Requires of a Chimney in Broward County
On this coastline the questions that decide a chimney job are written down: what wind speed roof-level work answers to, how much free area a spark arrestor needs, whether your address falls inside the coastal building zone, and which desk issues the permit. This page collects the Florida Building Code sections and the Broward County rules we cite most often on Pompano Beach roofs, with the numbers, so you can check them before anyone quotes you.

Broward Wind Loads and the Coastal Metal Rules
Broward County sits inside the High-Velocity Hurricane Zone, and Section 1620.2 of the Florida Building Code assigns the county its own design wind speeds: 156 mph for Risk Category I, 170 mph for Risk Category II, and 180 mph for Risk Category III and IV, each stated as a 3-second gust. Buildings are treated as Exposure Category C unless Category D applies. A single-family home answers to the 170 mph number, so anything fastened at roof level is engineered against that figure rather than a generic national wind map.
Section 1522 carries that logic onto the roof surface itself. Structures and equipment built on or attached to a roof are designed and constructed under the Florida Building Code, with supports answering to the Chapter 16 loading requirements, and the section prohibits the use of wood sleepers outright. Salt geography is drawn separately. Florida Statute 161.54 sets the coastal building zone as the land from the seasonal high-water line landward to a line 1,500 feet landward of the coastal construction control line, and on a coastal barrier island that zone runs 5,000 feet landward of the control line or covers the entire island, whichever is less.
The code then names metals. Section 1523.6.5.2.11.1 requires tile fasteners used in coastal building zones to be copper, monel, aluminum, or stainless steel; any other metal must pass 1,000 hours of salt-spray corrosion testing under TAS 114, Appendix E, Section 2 (ASTM G 85). Section 1517.5.1 holds roofing nails to that same corrosion standard and requires the carton or its label to state compliance. NASA's beachside test site on Florida's Atlantic coast, 200 feet from the mean high tide line, is documented by ASM as one of the most corrosive naturally occurring environments, with carbon-steel coupons measuring 0.127 to 0.51 mm of loss per year.
The Permit Baseline and What Changed on July 1, 2026
Start with the baseline. Florida Building Code Section 105.1 requires an owner or the owner's authorized agent to apply to the building official and obtain a permit before constructing, enlarging, altering, repairing, moving, or demolishing a building or structure. Section 105.2.2 allows ordinary minor repairs with the building official's approval and no permit, but the carve-out is narrow: it does not extend to cutting away any wall or partition, removing or cutting a structural beam, or removing or changing a required means of egress. Repair work is presumed permittable until the building official says otherwise.
Effective July 1, 2026, Florida Statute 553.79(1)(g) requires a local government that issues building permits to exempt an owner of a single-family dwelling from obtaining a permit for work valued below the threshold the statute sets. The exclusions carry more weight than the exemption. Electrical, plumbing, structural, mechanical, and gas work are excluded, and so is any property partially or entirely located in a flood hazard area as defined by the Florida Building Code. FEMA's Flood Map Service Center is the official public source for flood hazard information, searchable by address.
Two further conditions sit inside the same paragraph: a project may not be divided into more than one project to evade the requirement, and the exemption must be requested in writing from the local enforcement agency before work begins, with documentation showing the nature and value of the work. Where that request goes depends on the address. Broward County's Building Code Division regulates construction in unincorporated Broward County and in cities served under agreement with the county, so most Broward homes are permitted through their own municipal building department. Approved products are searchable statewide on the Building Code Information System at floridabuilding.org under Product Approval.
What the Four-Point Roof Section Puts on Record
The roof section of the Citizens four-point form is a records document before it is anything else. It asks for the covering material, the roof's age in years, its remaining useful life in years, the date of the last update, whether that update was a full replacement, and the date of the last roofing permit. Those are answers a homeowner either has on paper or does not, and the form has a line for each of them whether or not any paperwork exists to fill it in.
Photographs are not optional additions to those answers. The form's minimum photo requirements call for a photograph of each roof slope, plus photographs of all hazards or deficiencies. That means the roof plane around a chimney is not summarized in a sentence; it is shown. Staining, displaced metal, open joints, or a repair that was never closed out appear in the images attached to the form, sitting next to the written answer about remaining useful life and the date of the last permit.
The form carries one more note worth knowing: with photographs of each roof slope, the roof section can take the place of the separate Roof Inspection Form. One well-documented roof section can satisfy two requirements at once, which raises the value of ordinary paperwork. A permit pulled for roof-side chimney work produces a date that answers the form's permit question directly, and photographs taken before and after that work give the roof section something specific to show rather than a blank line.

Frequently Asked Questions
What does the Florida code require of a spark arrestor?
Section R1003.9.2 of the Florida Building Code, Residential, sets it out precisely. Where a spark arrestor is installed on a masonry chimney, its net free area must be not less than four times the net free area of the outlet. The screen material must have heat and corrosion resistance equivalent to 19-gage galvanized steel or 24-gage stainless steel. Its openings must not permit passage of spheres larger than 1/2 inch, and must not block passage of spheres smaller than 3/8 inch. It must also be located so that it is accessible for cleaning, and be removable for chimney maintenance.
Who issues the permit for chimney work in Broward County?
That depends on the address. Broward County's Building Code Division regulates construction in unincorporated Broward County and in cities served under agreement with the county, which means most Broward addresses are permitted through their own city building department rather than through the county. Broward also maintains its own code body. The Board of Rules and Appeals convenes to consider proposed amendments to the Florida Building and Fire Prevention codes, to hear appeals on decisions made by Building and Fire Code Officials, and to render formal interpretations on the precise meanings of code sections that may be disputed. It passed Broward's amendments to the FBC 8th Edition (2023) on October 12, 2023, effective December 31, 2023.
How do I tell whether the coastal metal rules reach my address?
Florida Statute 161.54 draws the line by distance from the coastal construction control line. The coastal building zone is the land area from the seasonal high-water line landward to a line 1,500 feet landward from that control line. On a coastal barrier island, the zone runs from the seasonal high-water line to a line 5,000 feet landward from the control line, or the entire island, whichever is less. Inside that zone, Section 1523.6.5.2.11.1 limits tile fasteners to copper, monel, aluminum, or stainless steel unless the fastener has passed 1,000 hours of salt-spray testing under TAS 114, Appendix E, Section 2.
What wind speed does roof-level work in Broward answer to?
Section 1620.2 assigns Broward County a 3-second-gust design wind speed of 156 mph for Risk Category I, 170 mph for Risk Category II, and 180 mph for Risk Category III and IV, with Exposure Category C presumed unless Category D applies. A single-family home falls under Risk Category II. Section 1522 then requires structures and equipment on a roof to be designed and constructed under the Florida Building Code, with rooftop-mounted equipment and its supports meeting the Chapter 16 loading requirements, and it prohibits the use of wood sleepers.
