Summary

Walton County caps lot coverage through an Impervious Surface Ratio table tied to each zoning district: Residential Preservation lots, common along older South Walton streets, are held to 60 percent impervious coverage, while the beachfront Coastal Center district is allowed 75 percent, both set out in LDC § 2.04.00's density, intensity and ISR chart.

These county ordinances apply to unincorporated areas of Walton County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Zoning District Maximum Gross Density Dwelling Units (DU) per Acre Intensity (Floor Area Ratio or FAR) Impervious Surface Ratio (ISR) ... Residential Preservation (RP) 1 du/lot 0.50 (50%) 0.60 (60%) ... Coastal Center (CC) 8 du/acre 1.50 (150%) 0.75 (75%)

Full Breakdown

00, the Summary of Density, Intensity and Impervious Surface Ratio by Zoning District, lists every district's maximum gross density, Floor Area Ratio and Impervious Surface Ratio (ISR) side by side. 50 (50%) depending on the bonus applied. ISR measures total impervious cover, not just the building footprint, so driveways, parking, patios and pool decks all count toward the cap that Planning and Development Services checks during site-plan and building-permit review. 5, CR 2/1) show "N/A" for both FAR and ISR because those large-lot districts are instead controlled through the wetlands and natural-community preservation standards in LDC Chapter IV rather than a numeric coverage ceiling.

Violations & Fines

Exceeding a district's Impervious Surface Ratio is enforced under LDC Chapter VII: a Code Enforcement Officer can issue a notice of violation requiring the owner to remove or permit the excess impervious area, and an uncorrected violation escalates to a citation with a civil fine of up to $500 per violation before the county's Code Compliance Special Magistrate.

Frequently Asked Questions

What is the maximum lot coverage on a 30A beachfront lot?
It depends on the district shown on the county's Official Zoning Map; Coastal Center parcels are capped at a 0.75 (75%) Impervious Surface Ratio under LDC § 2.04.00, while the more intense Coastal Center Mixed Use and Village Mixed Use districts allow up to 0.85 (85%).
Why do some districts show "N/A" for lot coverage?
Conservation Residential districts (CR 1/10, CR 1/2.5 and CR 2/1) list "N/A" for both Floor Area Ratio and Impervious Surface Ratio in LDC § 2.04.00 because those large-lot districts are governed instead by the wetlands and natural-community preservation limits in Chapter IV of the Land Development Code.
Does a pool deck count toward the impervious surface limit?
Yes. Impervious Surface Ratio measures all impervious cover on the lot, not just the building footprint, so driveways, patios and pool decks all count against the percentage cap set for the parcel's zoning district in LDC § 2.04.00.
