HVHZ — High Velocity Hurricane Zone
Siesta Key Is in Florida's Most Demanding Wind Zone
Siesta Key falls within Florida's High Velocity Hurricane Zone (HVHZ) — the most rigorous wind resistance designation in the state. HVHZ applies to barrier island and certain coastal properties that face direct storm exposure, and it requires products that have passed Miami-Dade Protocol testing: PA 201 (large-missile impact), PA 202 (cyclic wind pressure), and PA 203 (uniform static pressure).
Every impact window and door we install in Siesta Key carries an HVHZ-rated Florida Product Approval and a Miami-Dade Notice of Acceptance (NOA) number confirming compliance. "Florida Product Approved impact glass" is not the same as HVHZ-rated glass — the distinction matters here, and we verify it for every product before your installation begins.

Local Questions
About Siesta Key Impact Window Installations
What HVHZ rating is required on Siesta Key?
All Siesta Key properties fall within Florida's High Velocity Hurricane Zone. This requires impact windows and doors that have passed Miami-Dade County Protocol PA 201/202/203 — the highest impact and wind pressure test standard in Florida. All products we install on Siesta Key carry HVHZ-certified Florida Product Approvals with Miami-Dade NOA documentation.
Common Questions
Impact Windows & Doors in Sarasota County
What are the wind zone requirements for Sarasota County impact windows?
Sarasota County coastal communities — Siesta Key, Lido Key, Casey Key, Venice Beach, and waterfront Sarasota — are in Florida's High Velocity Hurricane Zone and require HVHZ-rated impact products. Inland areas like North Port, Lake Sarasota, and Nokomis fall in lower wind zones but still require Florida Product Approved impact glazing. We confirm your parcel's wind speed designation before recommending any product.
How does the Sarasota County permit process work?
Sarasota County Development Services requires permits for all window and door replacements. We submit the full permit package — product approvals, drawings, contractor license — and handle all communication with the county through final inspection. Sarasota City and unincorporated Sarasota County have separate building departments, and we're familiar with both processes.
Are there historic district considerations in Sarasota?
Yes. Parts of Sarasota have historic overlay districts — particularly in Laurel Park and near downtown — where the Historic Preservation Board may review exterior changes including window replacements. We've worked on historic Sarasota properties and can help identify whether your home requires board review, and recommend impact window profiles that satisfy historic guidelines.
Can I get a wind insurance discount in Sarasota County after installing impact windows?
Yes. Sarasota County homeowners with certified impact windows and doors qualify for wind mitigation credits from Citizens Insurance and most private insurers. The credits are based on opening protection ratings verified during a wind mitigation inspection. We provide all product documentation needed for that inspection after every installation.
