Setbacks & Height Limits in Fresno

This guide explains the basic setback and height rules that apply to residential construction in Fresno. These numbers depend on your exact zoning district, overlay zones, and lot geometry, so always confirm with the City of Fresno Development & Resource Management Department before finalizing plans.

What Are Setbacks?

A setback is the minimum required distance between a building and a lot line. Setbacks are measured from the property line to the nearest point of the building (typically the wall, but eaves, bay windows, and chimneys can have their own rules).

Fresno's Citywide Development Code specifies front, side, and rear setbacks separately for each zoning district. Corner lots have two "front" setbacks (one per street frontage) and typically one interior side and one rear.

Typical Residential Setbacks

For the most common Fresno single-family residential zones, expect approximately:

These are typical values — your specific lot and zone may have different requirements. Higher-density residential zones, mixed-use zones, and commercial zones all have separate setback schedules.

Height Limits

Maximum building height in Fresno single-family residential zones is typically 30 ft or two stories, measured from average grade to the highest point of the roof (or to a specified reference plane like the midpoint of a pitched roof). RM-1 and higher-density zones allow up to 35 ft or three stories.

Height rules get more complicated in:

• Downtown Neighborhoods Specific Plan areas — form-based code standards apply, with different height envelopes keyed to building type
• Airport overlay districts — Fresno Yosemite International and Fresno Chandler Executive Airport impose FAA Part 77 surfaces that can cap height
• Agricultural buffer zones — transitional areas along the urban-agricultural edge
• Historic or design review zones — context-based height limits may apply
• Mixed-use and commercial zones — generally allow greater height, often tied to FAR

Lot Coverage and FAR

Beyond setbacks and height, two other numbers shape how much you can build:

• Lot coverage — the percentage of the lot covered by buildings. Fresno residential zones allow 40% (RS-1), 50% (RS-3), 55% (RS-5), and 60% (RM-1).
• Floor Area Ratio (FAR) — the ratio of total floor area to lot area. RM-1 in Fresno uses a FAR of 1.0. A FAR of 1.0 on a 6,000 sq ft lot allows 6,000 sq ft of floor area.

Not every zone uses FAR; Fresno applies it primarily to multi-family and mixed-use districts.

Common Exceptions and Encroachments

Most zoning codes allow certain features to project into required setbacks. Typical allowances in Fresno include:

• Eaves and gutters (usually up to 2 ft)
• Chimneys (up to 2 ft)
• Uncovered porches, stoops, and steps
• Air conditioning condensers (subject to sound limits)
• Bay windows (limited projection)

Fences, retaining walls, and accessory structures often have separate rules — check the Citywide Development Code section on accessory structures.

State ADU Overrides

If your project is an Accessory Dwelling Unit (ADU), California state law overrides local setback and height rules. Under AB 68, SB 13, AB 881, and AB 2221, Fresno must allow detached ADUs with a minimum 4 ft side and rear setback and up to 16 ft in height (or 18 ft for two-story ADUs on lots meeting certain criteria). These state standards take precedence over the base RS or RM zone requirements. See the ADU rules page for details.

How to Look Up Your Specific Requirements

1. Find your zoning district — use the Fresno zoning map (linked in sources above)
2. Read the district regulations — your zone chapter in the Citywide Development Code lists setbacks, height, lot coverage, and FAR
3. Check for overlays — Downtown Neighborhoods Specific Plan, agricultural buffer, airport, and others can modify the base rules
4. Ask planning staff — the Development & Resource Management Department offers zoning information at the public counter before you commit to design

Variances

If your project cannot meet the strict letter of the zoning code, you may apply for a variance — a formal request to deviate from the rules based on hardship specific to your lot. Variances are discretionary and typically require public hearings. See the Variance Application Guide for the general process.
