Harris County has no lot coverage restrictions in unincorporated areas due to its lack of zoning. Maximum impervious cover may be effectively limited by stormwater detention requirements from the Harris County Flood Control District. Deed restrictions may impose coverage limits.
Without zoning, unincorporated Harris County has no maximum lot coverage or impervious surface percentage requirements. However, the Harris County Flood Control District's detention requirements effectively limit impervious coverage on larger developments by requiring on-site stormwater detention for increased runoff. Subdivision plats and deed restrictions frequently specify maximum lot coverage percentages, typically 40-60% for residential properties. These are enforced through civil action, not county code enforcement. The county's stormwater quality permit requirements also indirectly address lot coverage through post-construction runoff management standards.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Harris County code enforcement directly for current fines, enforcement procedures, and hearing options.
