Violations & Fines
Building within the required front, side, or rear setback without an approved variance or applicable exception is a zoning violation enforceable under the Municipal Code's general penalty, Section 1-2.01. It carries misdemeanor exposure of up to a $1,000 fine and six months in county jail, or the City Attorney may pursue it as an infraction with fines starting at $100 and rising to $500 for repeat violations within a year. Code Enforcement can order an encroaching structure removed or modified, and each day it remains is treated as a separate violation.
