My back slab is 10 by 12. What does it cost to grow it to 16 by 20?
A 16 by 20 is 320 sq ft, which at $7 to $12 per sq ft is $2,240 to $3,840. Your existing 120 sq ft stays, so the 200 sq ft you add runs $1,400 to $2,400. Tear-out, if the old edge is cracked, is extra, and the free written estimate lists it separately.
Can concrete patio contractors in Bayonet Point pour a slab now for a screen enclosure I'll build later?
Pasco treats a slab intended for a future structure as permit work with sealed plans from a design professional, so the plain flatwork exemption doesn't cover it. We can quote it that way, with the footing the enclosure needs, or quote a plain slab that stays open. Tell us your plan at the walk-through.
My lot is near Bear Creek. Is a small slab still permit-free?
Pasco's current exemption sheet doesn't exclude flood zones from the under-500 sq ft flatwork line, but the $7,500 rule does exclude them, and the older 2/18/2026 sheet still linked from the county site excluded flood-zone parcels from its whole list. Look up your zone on the county flood page, then confirm with Building Construction Services before you rely on the exemption.
My mail says Port Richey or Hudson. Which office handles my pour?
It is a census-designated place with no city government. Unincorporated parcels go to Pasco County Building Construction Services, whatever the mailing city says. The ZIP codes here are 34667 and 34668. If your parcel is inside the City of Port Richey, that city's rules apply instead.
I live off Fivay Road near Bayonet Point Hospital. Is my patio a Bayonet Point job?
The hospital carries the Bayonet Point name, but the Census geocoder puts 14000 Fivay Rd inside the neighboring Hudson CDP. For a patio it doesn't change the office: both are unincorporated Pasco, so Building Construction Services handles it. The flood zone can differ street to street, so we look up your parcel.
My plan is 22 by 24. Is that still a no-permit slab?
Not under the flatwork line. 22 by 24 is 528 sq ft, over 500, and runs $3,696 to $6,336 at $7 to $12 per sq ft. Because that's under $7,500, you or the contractor can file Pasco's written exemption request with the contract, unless the lot is in a flood hazard area. Or trim it to 20 by 24, 480 sq ft, at $3,360 to $5,760. The free written estimate shows both.
