Many Florida properties, including inland ones, sit in FEMA flood zones. If yours does, the site plan usually shows the flood zone and elevations, and an elevation certificate may be required.

Do I need a notice of commencement in Seminole County, FL?

Under Florida law, a notice of commencement is required for improvements with a direct contract over $5,000. It is recorded with the clerk of court before the first inspection. Repair or replacement of an existing heating or air conditioning system under $15,000 is exempt.

Often, but not always. Many offices accept an existing survey or recorded plat for small projects, while others ask for a current boundary survey. We tell you what applies before you pay.
