Full Breakdown
Fresno Municipal Code § 15-903, Table 15-903-2 (Building Form and Location Standards - Residential Single-Unit Districts) sets minimum setbacks in feet across the RE, RS-1, RS-2, RS-3, RS-4, and RS-5 districts. Front setbacks run 35 feet in RE/RS-1, 30 feet in RS-2, 25 feet in RS-3, and 13 feet in RS-4/RS-5 (reduced further to 8 or 5 feet with an Enhanced Streetscape design under § 15-904-B). Interior side setbacks range from 10 feet in RE/RS-1/RS-2 down to a 10-foot total split (minimum 4 feet per side) in RS-4 and an 8-foot total split (minimum 3 feet per side) in RS-5.
Rear setbacks are 20 feet in RE through RS-3, dropping to 10 feet in RS-4/RS-5, while any lot backing a freeway or railroad must keep a flat 50-foot setback regardless of district. Section 15-313 governs how these lines are measured: front setbacks run from the back of the sidewalk (or curb, or property line, if no sidewalk exists) to the nearest point of the structure, side setbacks are measured from the interior property line, and no building may encroach into a recorded easement without an authorized covenant.
Section 15-904-A layers on block-context rules, where half or more of a blockface is already built out, a new home's front setback cannot exceed 110 percent or fall below 90 percent of the neighboring average, plus a water-efficient landscaping incentive that can shave up to three feet off the minimum front setback, never below three feet.
Violations & Fines
Building or expanding a structure that encroaches into a required setback without an approved encroachment, variance, or Article 52 development permit is a Development Code violation enforceable by the Planning and Development Department and Code Enforcement, which can require removal or reconstruction of the noncompliant portion of the structure at the owner's expense.
