Chowchilla — Development Standards

Last reviewed: July 1, 2026

Overview

This page summarizes the Chowchilla municipal zoning ordinance (Title/Chapters numbered in the text as 18.xx) controls for development standards: setbacks, heights, lot coverage, lot dimensions, and related bulk rules that determine what you can build on a parcel. For quick context see the city's zoning overview at Chowchilla Zoning. This page pulls the local rules directly from the municipal code chapters that govern each district and points to the specific controlling sections so you can verify parcel‑specific limits.

District-by-district guidance below restates the ordinance in plain English and highlights the decision‑relevant numbers. Where the code uses a calculation (for example "coverage determined by setbacks, parking, and open space") I explain the practical implication; where the ordinance is silent I mark that as "Not found in retrieved materials." All quoted numeric controls are followed by the exact ordinance citation.

R-L (Residential Low Density)

• Purpose & typical uses: single‑family residential lots and accessory uses; chapter identified by references to the R-L zone.
• Key dimensional standards:
  • Front setback: 25 ft minimum from front lot line on local streets; 35 ft where lot fronts a collector or arterial. § 18.10.070
  • Rear setback: 30 ft for one‑story, 40 ft for multi‑story; duplexes/urban lot splits may use reduced setbacks as allowed by state law. § 18.10.070
  • Interior side setback: 10 ft (one‑story) / 15 ft (multi‑story); urban lot split/duplex exceptions noted. § 18.10.070
  • Street side setback: 25 ft on local streets / 35 ft on collector/arterial. § 18.10.070
  • Max height: 35 ft. § 18.10.090
  • Lot coverage: 40% maximum coverage in the R-L (expressly stated for the R‑L zone). § 18.10.060
  • Distance between structures: minimum 10 ft (subject to building code). § 18.10.080

Practical note: the R‑L code explicitly ties coverage to a numeric cap (40%) and sets clear front/rear/side offsets—these are the primary constraints for single‑family development. Verify with the jurisdiction for parcel‑level exceptions (corner lots, alley access, easements). § 18.10.060–18.10.090

R‑M (Residential Medium density: R‑M‑5 and R‑M‑6)

• Purpose & typical uses: small‑lot multi‑unit developments; the code breaks medium density into R‑M‑5 and R‑M‑6 subzones.
• Key dimensional standards (per subzone):
  • Minimum lot area: R‑M‑5 = 5,000 sq ft (with exceptions in § 18.12.100); R‑M‑6 = 6,000 sq ft. § 18.12.030
  • Minimum lot frontage/width/depth: frontage 40 ft minimum; R‑M‑5: 50 ft (interior) / 60 ft (corner) width, 90 ft depth (exceptions noted); R‑M‑6: 60 ft / 70 ft width, 100 ft depth. § 18.12.040
  • Dwelling units per lot: generally no more than 2 dwelling units per lot, unless ADU allowed per local ADU section. § 18.12.050
  • Coverage: determined by combined setback, accessory, and parking requirements (no single percent stated). § 18.12.060
  • Setbacks: front 15 ft (livable) / 20 ft (garages/carports); rear 10 ft (one story) / 20 ft (multi‑story) with urban lot split/duplex allowances; side and street side setbacks per § 18.12.070. § 18.12.070
  • Usable open space: minimum 400 sq ft per dwelling unit (min 15 ft wide) in at least some R‑M contexts. § 18.12.150

Practical note: the R‑M chapters set dimensional minima and then let coverage be the residual of setbacks, open space and parking. For design decisions you will need to model parking and usable open space to know allowed building footprint. § 18.12.060, § 18.12.150

MX‑D (Downtown Mixed Use Commercial)

• Purpose & typical uses: downtown mix of retail, office and residential in a walkable pattern. § 18.26.010–.020
• Key dimensional standards:
  • Front setback: buildings are generally to be placed at the front lot line (exceptions for entries/patios). § 18.26.060(B)
  • Rear setback: may be 0 ft, except where abutting residential or other sensitive zones then 15 ft. § 18.26.060(C)
  • Side setback: may be 0 ft, except 15 ft where abutting specified zones. § 18.26.060(D)
  • Height: up to 50 ft generally; reduced to 35 ft where rear lot line abuts certain residential or public zones. § 18.26.080
  • Coverage: determined by setback/open space/parking rules (no single percent). § 18.26.050

Practical note: the downtown MX‑D intentionally permits zero side/rear setbacks and higher heights to encourage compact urban form, but imposes step‑downs and 15‑ft buffers where MX abuts residential/PF/OS zones—plan edges accordingly. § 18.26.060–.080

O (Office)

• Purpose & typical uses: professional and non‑retail commercial uses near neighborhoods. § 18.30.010–.020
• Dimensional controls:
  • Front setback: 15 ft minimum. § 18.30.060(B)
  • Rear setback: 15 ft minimum. § 18.30.060(C)
  • Side setback: 5 ft from interior side lot lines; 15 ft if side abuts a public street or specified residential zones. § 18.30.060(D)
  • Height: maximum 35 ft (with CUP possible for taller). § 18.30.080
  • Coverage: set by setbacks, open space, and parking requirements. § 18.30.050

PF (Public Facilities)

• Purpose & typical uses: parks, city facilities, schools, wastewater, fairgrounds, airport, etc. § 18.36.010
• Dimensional controls:
  • No minimum lot area in PF. § 18.36.030
  • Front setback: 15 ft. § 18.36.060(B)
  • Rear setback: 15 ft (or 25 ft where rear abuts R‑L, R‑M, R‑MH, R‑H). § 18.36.060(C)
  • Side setback: 5 ft interior / 10 ft street side. § 18.36.060(D)
  • Height: 50 ft maximum. § 18.36.080

C‑H (Highway Commercial / Commercial‑High)

• The code references a C‑H commercial district for which sign and general provisions are in Chapter 18.24. Typical rules require activities to be enclosed, mechanical equipment setbacks, and compliance with Chapter 18.50 standards. § 18.24.140–.150
  • Signs: governed by Chapter 18.56 (see § 18.24.140). § 18.24.140
  • Mechanical equipment: 5 ft from side/rear lots abutting certain residential zones. § 18.24.150(B)

Practical note: for commercial sites plan for parking and screening rules in Chapters 18.50–18.56 (referenced in the C‑H provisions). § 18.24.150(C)

Accessory structures (detached garages, sheds, etc.)

• General accessory structure numeric limits and siting rules are called out (plate line heights, roof pitch, ridge height, and when building permits are required):
  • Walls must be ≥ 3 ft from rear/side lot lines; eaves ≥ 2 ft from rear/side lot lines. § 18.14.120
  • Plate line height maximum 10 ft; roof pitch maximum 4:12; ridge maximum 12 ft. § 18.14.120 (plate/roof limits)
  • Any accessory structure > 120 sq ft requires a building permit. § 18.14.120(H)
  • Other items: pools 5 ft setbacks; decks/platforms over 2 ft set back 5 ft (rear/interior) and 10 ft (street side). § 18.14.130

Practical note: these accessory rules are stricter (low plate heights, low ridge) than many jurisdictions; confirm whether local ADU provisions modify these limits (see ADU section references below). § 18.14.120–18.14.130

Parking, landscaping and parking placement

• Required parking is governed by Chapter 18.54 and the code repeatedly states parking cannot be located within building setback areas; setback/landscape buffers are required adjacent to street frontages. § 18.14.140(B); § 18.30.100(B)
• Landscaping requirements are enforced via Chapter 18.52; front and visible setback areas must be landscaped (or in some cases permitted artificial turf/permeable surfaces). § 18.16.160(A–B)

Practical note: plan your footprint so that required parking stalls are not in front or street‑side setback areas and allocate the buffer landscaping between curb and parking where required. For the municipal parking rules consult the city's parking page for summary guidance on typical stall counts and layout. Chowchilla Parking.

Risks & Ambiguities

Plain‑English summary

Chowchilla’s zoning chapters set district‑specific numeric rules for setbacks, height, and coverage (for example R‑L caps lot coverage at 40% and limits height to 35 ft, while MX‑D allows buildings at the front lot line and up to 50 ft except where it must step down to 35 ft near residences). Always cross‑check required parking, landscaping, and any state ADU rules that can override local accessory limits; when in doubt, confirm parcel specifics with planning staff. § 18.10.060–.090; § 18.26.060–.080; § 18.12.060
