Sizing a patio when the fence is a few steps from the door
On a tight yard the slab is a measuring job before it's a pour. Subtract the door swing, a walkway to the side gate, the air-conditioner pad and a strip along the fence, and the pour is whatever's left. A 12 by 14 is 168 sq ft, a 14 by 16 is 224 sq ft and a 16 by 16 is 256. At $7 to $12 per sq ft the last two run $1,568 to $2,688 and $1,792 to $3,072. Each number becomes a free written estimate after we see the yard, not before.
About 82 percent of the housing units here are single-family detached homes. Our concrete patio contractors page covers the build from grade stake to finish. This page covers what changes on this ground.
Zone X and the $7,500 request: what a larger patio can use
Pasco's exemption sheet frees "non-structural concrete flatwork, under 500 square feet (per parcel), not to be built on." That covers the sizes above. A bigger pour may have a second path: the state's under-$7,500 exemption for single-family work, which is off the table on property in a flood hazard area. About 84 percent of the flood sample points here are FEMA zone X, outside those areas, so the request is open on most of the ground we sampled. Check your own parcel, not the average. A 20 by 30 patio is 600 sq ft, which at $7 to $12 per sq ft is $4,200 to $7,200, a free written estimate away.
The catch is paperwork. You or the contractor files a written request with the contract. Splitting a job to stay under the number isn't allowed, and structural work is excluded. Whether a given slab qualifies is the county's call, not ours. The Hernando and Pasco concrete permit guide walks through the request. If your lot lands in a mapped Special Flood Hazard Area, the $7,500 route is out, and the flatwork line is worth confirming with Pasco Building Construction Services in writing: the current sheet doesn't exclude flood zones from it, but the older 2/18/2026 sheet still linked from the county site does.
