Colfax — Variances and Exceptions

Last reviewed: July 1, 2026

Overview

Variances and exceptions in Colfax are governed by Title 17 — ZONING of the Colfax Municipal Code (the local “zoning ordinance”). Colfax distinguishes between administrative deviations handled by the Planning Director and formal variances heard by the Planning Commission; the code sets a clear numeric threshold for administrative vs. discretionary review and prescribes findings the approval authority must make before granting relief. See the city's zoning overview for general context.

Important quick points up front:

• An administrative deviation (an “administrative variance” or permit) may be approved by the Planning Director for limited departures from development standards (up to 35%) (§ 17.32.020) .
• Anything exceeding 35% (or certain topic areas such as parking reductions) is a variance decided by the Planning Commission and requires the findings in § 17.40.070.
• The code expressly prohibits using a variance to authorize a use that is not already permitted in the zone (§ 17.32.020).

How Colfax defines and allocates review

• Variance (VAR). A formal variance is required to deviate from Title 17 development standards by more than 35%, and the Planning Commission is the default approval authority (§ 17.32.020).
• Administrative variances / deviations. Deviations up to 35% (or accessory-structure-specific departures) are processed administratively by the Planning Director (§ 17.32.020).
• Parking reductions. A variance to reduce required parking cannot be processed administratively; it requires the Planning Commission (§ 17.32.020) and local parking rules and adjustment procedures apply (§ 17.108.040–045).
• Findings required. Before approving a variance the approval authority must make the four findings listed in § 17.40.070.G (special circumstances, no special privileges, not allowing an otherwise prohibited use, and not detrimental to public health/safety/welfare) — these findings are facts-based and must be supported by substantial evidence.

Where the code discusses zoning maps, district interpretation, and boundary issues it gives the Planning Director authority to interpret district lines and to allow limited special exceptions for split lots (see Chapter 17.08 and related map boundary rules).

District-by-district guidance (where variances & exceptions commonly arise)

Below are the primary districts where applicants most often seek deviations. Each subsection lists the district name, its purpose, typical permitted uses that interact with variance requests, key dimensional standards (as relevant to variances), and where in the city the district most commonly applies (as described in Title 17).

Note: these are syntheses of the zoning tables and district chapters in Title 17; verify project-specific applicability with the Planning Department.

R-1 (Single-Family Residential)

• Purpose: Preserve single-family neighborhoods and low-density residential character.
• Typical permitted uses: Single-family dwellings, Accessory Dwelling Units (ADUs) (subject to ADU chapter), small community care facilities, and limited accessory uses (see § 17.72.020).
• Key dimensional standards often implicated in variances: front/side/rear setbacks, lot coverage, building height and fence height (see Chapter 17.72 and setbacks/exception rules). Note that certain projections and small encroachments are allowed as exceptions without a variance (e.g., eaves, bay windows up to 2.5 ft; see § 17.72.030D).
• Where it applies: predominant low-density neighborhoods (see zoning map; verify parcel zoning with planning staff). Verify ADU-specific rules (Chapter 17.196 referenced in the residential table notes).

R-M (Multi-Family Residential)

• Purpose: Allow multi-family housing and higher residential densities while preserving livability standards.
• Typical permitted uses: Multi-family dwellings, supportive and transitional housing, employee housing, ADUs in many cases; accessory uses as listed in the R-M table (§ 17.72.020).
• Key standards relevant to variances: lot width and area, setbacks, usable open space, and sometimes height (note: single-family dwellings in R-M must meet R-1-5 standards per note in the table). Administrative deviations up to 35% are an option for many dimensional items (§ 17.32.020).
• Where it applies: designated multi-family blocks and corridors per the zoning map. Verify with planning staff for parcel-specific conditions.

R-MHS (Manufactured Home / Special residential)

• Purpose: Standard for manufactured housing communities and higher-service residential types.
• Typical permitted uses: Mobilehome parks (CUP), single-family and accessory uses as allowed in the table; design review may modify standards for R-MHS (§ 17.72 notes).
• Key standards: lot layout, spacing and usable open space; many standards can be adjusted through design review or administrative permits depending on the issue.

Industrial / M (Industrial districts; general)

• Purpose: Accommodate a range of industrial and heavy commercial uses while protecting adjacent zones. See Chapter 17.80.
• Typical permitted uses: industrial, warehousing, manufacturing subject to Chapter 17.80 rules and special standards.
• Key dimensional standards: Chapter 17.80 states there are generally no height, area, or lot coverage requirements in industrial districts except where adjacent to other districts; variances may be required where an industrial proposal interfaces with residential standards. Exceptions to height limits for architectural/mechanical features are specifically allowed (up to 15%) (§ 17.80.030C).

Overlays (Historic zone / other overlays)

• Purpose: Overlay districts add design and locational constraints on top of base zoning (see Chapter 17.84). The Historic zone preserves Colfax’s small‑town historic core.
• Typical interaction with variances: Where overlay design guidelines produce a strict development standard that conflicts with a parcel’s physical constraints, applicants may request design exceptions or variances — but the overlay’s policy goals (e.g., preserving historic character) are a strong factor in the findings for approval (§ 17.84.020).
• Where it applies: properties mapped in the historic overlay and other special purpose zones; consult the overlay map.

Key decision‑relevant table (most-cited local rules)

Checklist (what an applicant must submit / demonstrate)

• Completed variance/permit application form with property owner’s signature (eligible applicant rules) (§ 17.36.030)
• Filing fee as set by City Council (per fee schedule) (§ 17.36.020)
• Site plan, elevations, and narrative showing existing conditions, special circumstances (size/shape/topography), and the minimum relief requested (§ 17.36.040; see findings criteria in § 17.40.070.G)
• Evidence that the requested relief does not authorize a use not permitted in the zone (variance limitation) (§ 17.32.020)
• Parking study or operations data for any parking adjustments/reductions (§ 17.108.040)
• Documentation for any concurrent approvals (design review, conditional use permit, CEQA paperwork) — concurrent processing rules apply (§ 17.32.030; § 17.36.090)
• Public notice compliance materials for hearings (mailing list, posted notice, legal descriptions) (§ 17.40.020–050)

(While preparing the submission, consult the city's pages for development standards, parking, and design review because variances often need to be coordinated with those processes.)

Risks & Ambiguities

Plain‑English summary

If your house or lot in Colfax needs relief from a setback, height, lot-size, or similar development rule, you can ask for an administrative deviation for modest changes (up to 35%) from the Planning Director; bigger departures or parking reductions must go to the Planning Commission as a variance and require the code’s four findings to be met — especially that there are unique property circumstances and that the variance won’t create special privileges or harm public welfare (§ 17.32.020; § 17.40.070).

(If your request also touches ADUs, setbacks and development standards, or parking, expect those chapters and programs to affect what relief is possible.)
