Fixed does not mean exempt
In the HVHZ, every exterior opening — residential or commercial — must be protected against wind-borne debris, by either shutters or impact-resistant windows. The provision addresses openings. It does not carve out openings that happen to be sealed shut.
Read alongside it the requirement that exterior wall cladding, surfacing and glazing within the lowest 30 feet of exterior building walls must resist large missile impact. Glazing is named explicitly, right next to cladding and surfacing. A fixed lite is glazing in an exterior wall within the lowest 30 feet of a Pembroke Pines house, which puts it squarely in the large-missile requirement with everything else.
If anything, the exposure argument runs the other way. A picture window is typically the biggest uninterrupted pane on the elevation, and it is usually pointed at whatever view the house was designed around — frequently the open side of the lot, with the least in front of it.
The 30-foot line, and the one case where it nearly matters
The code splits the wall into two bands. Below 30 feet: large missile. Above 30 feet: small missile. Almost everywhere in Pembroke Pines residential work, only the first band exists in practice, because a one- or two-story house never reaches the line.
The place homeowners think it might come into play is a tall stairwell or great-room picture window — the two-story pane over an entry. It does not. A two-story wall in a Pines house runs perhaps 20 to 22 feet; the top of that glass is still well inside the lowest 30 feet of exterior wall. Large missile applies to the whole unit.
This is one of the clearest expressions of what makes Broward different. In the rest of Florida, wind-borne debris regions are drawn by distance from the coastline, so the analysis starts with where the house is. Here it does not: the HVHZ consists of Miami-Dade and Broward Counties, it applies countywide, and the only geometry that matters is height above grade.
Large glass, per-opening design pressure
Fixed units are frequently the largest openings on a house, and size feeds directly into the design pressure calculation. Positive and negative design pressures are assigned opening by opening from the size, the height, the position on the wall, the exposure and the risk category — and the values for your picture window have to fall inside the approved range for the specific unit installed there.
Approval documents state maximum tested sizes. On big fixed glass that ceiling is a real design constraint, not a footnote: an opening can be wide enough that the answer is a different product, a mullion, or a reconfiguration into multiple units. Finding that out during the measure is routine. Finding it out after the order is not, which is a reason to prefer a bidder who measures before quoting.
This site publishes no design pressure values and no design wind speed for this city. Those numbers belong on your sealed plans and on the product approval, where they are tied to your actual openings rather than to a web page that has never seen your house.
Permitted the same way as everything else
Fixed glass replacement is permitted through the City of Pembroke Pines Building Department at 601 City Center Way, (954) 435-6502. Broward County’s zoning and building code provisions reach the Broward Municipal Services District and the unincorporated areas of the county — property inside a municipality is governed by that municipality, and Pembroke Pines is not one of the 22 municipalities the County serves under Inter-Local Service Agreements.
Where the direct contract exceeds $5,000, § 713.135, F.S. requires a copy of the notice of commencement to be filed with the issuing authority before the first inspection. A single large picture window can clear that threshold on its own.
