Two Pasco sheets, one canal-front lot
Pasco County's Building Construction page still links an older exemptions sheet, dated 2/18/2026, that says its list does not apply to parcels in special flood hazard areas. The current one, revised 6/30/2026, lists "non-structural concrete flatwork, under 500 square feet (per parcel), not to be built on" and does not repeat that flood carve-out. The separate state-law rule for work under $7,500 does exclude "any work on a property located partially or entirely within a flood hazard area."
So here's the straight answer for an AE canal lot. The $7,500 route is out. On the current sheet's wording a small plain patio fits the flatwork line, but the older sheet says the list doesn't apply there, so get the county's answer in writing before the forms go in. We look up your zone on the FEMA map first, then draft the estimate with the permit step it assumes. The Hernando and Pasco permit guide lists the office and the online portal. Our concrete patio contractors page covers the build itself.
Which flood zone the patio sits in, and the V and coastal AE checklist
The flood sample inside Hudson's boundary came out about 58 percent AE coastal floodplain, 4 percent VE, 27 percent X minimal hazard and 12 percent X in the 0.2 percent chance coastal zone. Roughly six in ten points sat in a Special Flood Hazard Area, so check your own parcel and ignore the average.
Your zone changes the patio job. In V and coastal AE zones, Pasco keeps a separate "Checklist for V and Coastal AE Zone Design Certificates." Ask about it first if your patio is part of a larger project with a roof. Pasco also says fill placed in a floodplain needs cup-for-cup compensatory storage, so we don't promise to build the patio up with dirt. A patio poured at the existing grade, sloped away from the house, keeps added fill out of the question. That is why we, as concrete patio contractors in Hudson, give every number as a free written estimate after we see the site.
