Commercial Window Replacement Types by Building
Each building type brings its own mix of openings, occupants and code limits.
Apartment and Multifamily Window Replacement
Height decides which energy rules apply. Apartment buildings of three stories or fewer use the residential limits; from four stories up, the commercial table governs. The code lets replacement units average their U-factor by area, but only within one category, so fixed and operable windows are averaged separately.
- Fixed windows: U-0.50 maximum.
- Operable windows: U-0.65 maximum.
Office and Medical Building Windows
Fixed and operable units sit in separate energy-table categories with different limits. Shading earns room on solar heat gain: an overhang with a projection factor of 0.5 or more lets glass go to an SHGC of 0.40, against 0.25 on an unshaded wall. Ask that the quote list each unit's U-factor and SHGC beside its impact approval number.
Hotel and Short-Term Rental Windows
Balcony sliders and big fixed panes carry safety-glazing rules on top of impact approval. Florida's building code counts glass in every sliding-door panel as a hazardous location, plus any pane over 9 square feet whose bottom edge sits under 18 inches with a walkway within 36 inches. Ask for a room-by-room schedule before blocking rooms out of inventory.
Retail Plazas and Mixed-Use Buildings
Ground-floor shopfronts sit on framing systems with heavy-use glass doors, which the energy code calls entrance doors and holds to a looser U-1.10. Display glass, storefront framing and ADA door hardware are covered on the storefront glass page; apartments or offices upstairs follow the categories above.

Commercial Window Code Points in Broward
Impact approval
Commercial openings face the same HVHZ impact tests as houses, and each unit needs an approved, labeled product. Above 30 feet the small-missile test applies instead of the 2x4.Energy table
In zone 1, SHGC is 0.25 on most walls at low shading, 0.33 facing within 45 degrees of north, and up to 0.40 under deep overhangs.Glazing area
Vertical glass is capped at 30% of the gross above-grade wall, or 40% with daylight-responsive controls in qualifying daylight zones.Safety glazing
Glass in doors, glass within 24 inches of a door edge and under 60 inches above the walking surface, and large low panes all need safety glazing.
What a Commercial Window Quote Should List
A property manager comparing bids needs the same line items from each one. Ask for them per opening, not as a building total.
Approval and pressure
The Florida or Miami-Dade approval number and the positive and negative design pressure from each unit's label.Energy category
Whether the unit counts as fixed, operable or an entrance door, with its U-factor and SHGC, plus the area-weighted average where the bid relies on one.Safety glazing
Which openings fall in a hazardous location and get safety glass.Sequence
Which floors, units or rooms are worked on each day, and how open walls are protected if weather turns.
Permits and Scheduling for Commercial Window Jobs
Window and door replacement in Pompano Beach always needs a city permit, filed with the Building Department at 100 W. Atlantic Blvd. On a contract over $5,000, a notice of commencement has to be filed before the first inspection. Ask who files the permit and the notice, and get that answer in the contract. In an occupied building, ask for a written schedule of which units are worked on which days, so tenants and guests can be told ahead and the property's own notice rules can be followed.
