What makes a lot buildable changes at every county line. These guides summarize the rules that actually decide it — zoning minimum lot size, setback envelopes, septic and sewer availability, slope, buffers, and flood exposure — then let you run any specific parcel through the same automated screen LotAnalyst uses.
Florida land feasibility is driven by flood elevation, wetlands, and septic approval far more than by slope. Counties administer zoning while the Department of Health approves onsite sewage systems, so a lot can be legally zoned for a house and still fail on soils.

Much of Texas has no county zoning at all. Buildability is instead controlled by recorded deed restrictions, subdivision plats, city ETJ rules, on-site sewage facility (OSSF) sizing, and groundwater availability.

Georgia counties zone aggressively by minimum lot size, and the state layers on a mandatory stream buffer. Older platted lots that fall below today's minimum are frequently still buildable as legal non-conforming lots of record.

North Carolina layers state riparian buffer rules and watershed overlays on top of county zoning, and mountain counties add steep-slope standards that can override the base district.

Tennessee buildability usually turns on soils and septic capacity. TDEC issues subsurface sewage disposal permits, and karst limestone geology means a large, flat, correctly zoned lot can still fail.

In Arizona the decisive questions are legal access and water. Cheap desert parcels are routinely landlocked, unserved by utilities, or sited in an unmapped wash.

Colorado land feasibility is a water-rights question first. A well permit is not automatic, and household-use-only permits restrict irrigation and livestock, which changes what rural buyers will pay.

South Carolina's coastal counties are dominated by flood elevation, wetlands, and stormwater rules; inland counties look much more like standard Southeast zoning-and-septic analysis.

Figures on this page are typical ranges compiled from published ordinances and public data for orientation only. Districts, overlays, and setbacks change — always verify the governing zoning district, minimum lot size, buffers, and septic requirements with the county planning office and health department before you buy or build.
