Full Breakdown
Under Ordinance Code § 654.129(b), every subdivision and building lot in Duval County must meet a maximum impervious surface ratio set by its zoning district: the share of the lot that can be covered by structures, driveways, patios and other non-absorbent surfaces. Ratios run from 15% in agricultural (AGR) districts up through 30-75% across the low- and medium-density residential (RR, RLD, RMD) districts, 85% in high-density residential and most commercial/industrial districts, and 95% downtown (CCBD). Section 656.223(f) bars any structure from providing less impervious surface than section 654.129 requires, tying the zoning code's lot-coverage rule directly to this table. The Planning and Development Department reviews compliance at plat and building-permit stage.
Violations & Fines
Building without a permit that exceeds the district's impervious surface ratio triggers plan rejection or a stop-work order from the Planning and Development Department until the site plan is revised to comply.
