Local Project Considerations

St. Petersburg: Regional Factors to Know Before You Build

🌀All windows in FL must meet impact resistance requirements under Florida Building Code — either impact-rated glass or an approved storm shutter system. Impact windows eliminate the need for shutters and carry a wind zone rating appropriate for your county. Verify the FL product approval number and wind zone before purchase — Miami-Dade products are rated higher than most inland Florida requirements.
💰St. Petersburg homeowners insurance carriers actively discount premiums for impact-rated window installations — discounts range from 5–30% of the wind premium portion, which is significant in FL's high-premium market. Get the actual discount in writing from your carrier before finalizing your window selection budget.
⚡Low-SHGC glass is essential in St. Petersburg's climate. Solar heat gain coefficient below 0.25 for south and west-facing windows reduces cooling load meaningfully in a long, hot Florida summer. Ask your window contractor for glass specifications by cardinal direction — blanket "Low-E" is not sufficient specification for St. Petersburg's climate.
