Summary
Santa Rosa County limits how much of a site can be covered by impervious surfaces. Within the Shoreline Protection Zone, total impervious surface, buildings, driveways, pools, walkways, is capped at 75% of the site. Residential buildable area is otherwise controlled by setbacks.
Total impervious surface, including but not limited to buildings, houses, parking lots, garages, accessory buildings, driveways, pools and walkways is limited to 75 percent of the land area of the entire site.
Full Breakdown
The county's LDC does not set a single residential building-coverage percentage; instead, buildable area on a typical lot is governed by the required setbacks in Table 2.05.01. Impervious-surface caps do apply in specific contexts: within the Shoreline Protection Zone, total impervious surface, including buildings, houses, parking, garages, accessory buildings, driveways, pools and walkways, is limited to 75% of the site's land area. Planned industrial development caps building lot coverage at 50% and impervious surface at 75%. All accessory structures count toward impervious-surface and lot-coverage calculations.
Violations & Fines
Exceeding impervious or coverage limits in a regulated zone requires stormwater review or a variance; unpermitted overbuilding is a code-enforcement and stormwater-compliance violation.
