Full Breakdown
Appendix A, Zoning Regulations, Section 6-1(c) sets single-family yard setbacks in the R-1, R-2, R-3, and AG districts where a block-front alignment hasn't already been established. The default front setback is twenty feet, reduced to ten feet where parking sits beneath an elevated structure. Each side yard needs a minimum five-foot setback measured to the main body of the house, though newly subdivided R-1 lots in suburban residential areas need at least ten feet on one side. The rear yard must equal at least fifteen percent of the lot's depth, but the code caps that requirement at thirty feet regardless of lot size, and up to forty percent of the rear yard may hold an accessory building or dwelling.
Violations & Fines
Zoning administrator enforcement; structures encroaching on required setbacks are ordered removed and building permits are withheld until the setback is corrected or a board of zoning appeals variance is granted.
