County
Structural engineering in Miami-Dade County.
Miami-Dade County is entirely within the High-Velocity Hurricane Zone, so every window, door, roof, and structure has to be designed for HVHZ wind pressures and use products approved for the zone. It is the most demanding product-approval environment in Florida.
We work across the whole county, in the City of Miami, Coral Gables, Hialeah, Doral, and Homestead as well as the unincorporated areas, and every package is reviewed and sealed by our Engineer of Record before it leaves the office.

What we typically engineer here.
- Impact window and door replacements to HVHZ pressures
- Re-roofs with roof-to-wall connection and attachment engineering
- Building recertification (30-year, then every 10) for aging buildings
- Sheds, screen enclosures, and accessory-structure anchorage
Who reviews your permit
Some Miami-Dade cities run their own building departments; other areas are reviewed by the county. Postal “Miami” covers both incorporated cities and unincorporated county, so the reviewing authority is confirmed per address before work starts.
DERM and environmental review
The county's environmental agency (DERM) can attach to a permit for flood, coastal, or environmental scopes even inside a municipality. Where it applies, those reviews are handled as separate disciplines on the package.
Recertification
Under county code §8-11(f), qualifying buildings are recertified beginning at 30 years of age (25 for coastal buildings), then every 10 years, the program long known as 40-year recertification, shortened in 2022. It is separate from the statewide milestone inspection, and a building can owe both.

Common questions
Miami-Dade County, FAQ
Is my Miami-Dade project in the HVHZ?
Yes, all of Miami-Dade County is in the High-Velocity Hurricane Zone, so opening protection and HVHZ-valid product approvals apply. The exact design pressures still depend on your address and building height, which we confirm per project.
Do Miami-Dade permits require a Miami-Dade NOA?
Products must carry an approval valid for the HVHZ, either a Miami-Dade NOA or a Florida Product Approval with explicit HVHZ acceptance. We verify approvals against the current source for each product rather than a cached listing.
Does the county or the city review my permit?
It depends on the address. Several Miami-Dade cities have their own building departments; other areas are reviewed by the county. We confirm the reviewing authority for your parcel before starting.
Does my older Miami-Dade building need recertification?
Under county code §8-11(f), qualifying buildings are recertified beginning at 30 years of age (25 for coastal buildings), then every 10 years, the program formerly known as 40-year recertification, shortened in 2022. Whether, and when, your building is due depends on its age, size, and location, which we confirm.
