Full Breakdown
Appendix A Zoning's area-requirements tables give a "maximum building coverage as a percentage of lot area" line for every use district. For R-1 single-family lots, R-1A large-lot single-family, and R-1T townhouse lots, that line simply reads "N/A": the city has never adopted a coverage or impervious-cover cap for these residential lots. Duplex-fourplex (R-2) and multifamily (R-3) lots are held to 50 percent building coverage instead, paired with a 10 percent minimum landscaped open-space requirement. The code separately defines "lot coverage" to include mobile homes, RVs, and other structures without a permanent foundation.
Violations & Fines
For R-2 and R-3 lots, building past 50 percent coverage falls under the district's prohibited-use clause, which bars any construction exceeding the maximum height, building coverage, or density required for that district; single-family (R-1/R-1A/R-1T) lots have no coverage limit to violate.
