Full Breakdown
1140 sets permissible lot coverage in the RE (Residential Estate) Zone at a maximum of 30 percent of the lot, a figure that expressly includes accessory buildings along with the main house. 1630. 3245 carves out one specific exclusion: shade structures are not included when calculating the maximum aggregate lot coverage of all buildings, so patio covers and similar shade features do not count against an RE lot's 30 percent ceiling or any other zone's cap. 08. 3245.
Violations & Fines
Building beyond the applicable lot coverage percentage is caught at plan-check and building-permit review; a structure built in violation of TMC section 10.08.1140 or the parallel zone limits is subject to permit denial, a recorded notice of violation under section 1.16.010, and Chapter 1.04 code enforcement, including infraction fines escalating from $100 to $500 for repeated violations of the same section within a year, plus a correction order to remove or reduce the offending coverage.
