Full Breakdown
The UDO's General Dimensional Requirements table sets a maximum impervious surface cover of 40% for the standard single-family residential districts (YR, AG, RS40 through RS7, RSQ, RM5, MH), rising to 45–60% and higher in denser multifamily/mixed-use districts. Separately, accessory structures are limited by area: they may not exceed five percent (5%) of the actual zoning-lot size (or the district's minimum lot size, whichever is larger), though an accessory structure up to 576 square feet is permitted in all districts regardless. An accessory structure also cannot occupy more than twenty-five percent (25%) of the required yard.
Violations & Fines
Exceeding impervious-cover or accessory-area limits is a UDO violation; larger accessory structures may be considered only through the Board of Adjustment special-use permit process.
