Full Breakdown
020 (Residential Districts General Development Standards). 5-acre-minimum RR (Rural Residential) district down to the 4,350-square-foot SF-2 zone. 5 feet per side, or for parcels under 5,000 square feet an averaged 12 feet combined for both sides with neither side allowed to go below 5 feet. Street-side setbacks on corner lots hold at 20 feet in every zone except SF-2, where they fall to 10 feet. Rear setbacks are 20 feet in all six zones. 140 (Setback Regulations and Exceptions) governs how these lines are measured, at right angles from the nearest point of the front, side or rear property line to the nearest wall of the structure, and lists narrow exemptions: fences and walls within the chapter's height limits, decks and similar grade-level features under 18 inches tall, and retaining walls under four feet.
The same section allows limited encroachments: a chimney or fireplace up to six feet wide may project 30 inches into a setback, and covered porches may extend up to six feet into a front yard, provided they stay at least three feet off the side property line. 150 rather than the primary-structure setback table.
Violations & Fines
Murrieta's Development Code carries no setback-specific fine schedule; violations fall under the citywide Section 1.32.010 (Violation--Penalty). Building or maintaining a structure that encroaches into a required setback can be cited as an infraction: $100 for a first offense, $200 for a second within a year, $500 for each further violation, or prosecuted as a misdemeanor carrying up to a $1,000 fine and six months in jail. The city may also sue to enjoin the encroachment under subsection C, or issue an administrative citation under Chapter 1.26.
