Fairfield — Variances and Exceptions

Variances and Exceptions under the Fairfield local zoning and planning code, with the controlling citations.

Last reviewed: July 2, 2026

Overview

This page explains how the City of Fairfield handles Variances, Exceptions, and related Waivers under the Fairfield Zoning (Title 25). It summarizes who decides, what may be changed, the legal findings required, timing rules for subdivisions, and the development districts where these processes are most often used. For procedural steps see § 25.41 for filing and processing and for the variance rules see § 25.40.8 .

Important internal resources (first mention of each is linked): consult the city pages on Fairfield Development Standards, Fairfield Parking, Fairfield Design Review, Fairfield Overlay Districts, Fairfield ADUs, Fairfield Signage, and the California Building Standards Code when building permits and code compliance are required.

What the code allows (short synthesis)

Variance — a discretionary deviation from development standards (setbacks, heights, lot coverage, parking dimensions, etc.) when unique property circumstances cause strict application to deny privileges enjoyed by similarly zoned neighbors; variances cannot change allowed uses or densities. See § 25.40.8 and the findings required in § 25.40.8.C .
Exception (subdivision / design exceptions) — the Planning Commission may grant exceptions from specific design standards for subdivisions or development where strict literal application would be impractical, subject to findings limiting special privilege. See § 25.158 .
Waiver (subdivision/common ownership and density-bonus waivers) — different waiver tracks exist: (a) waivers associated with subdivision/common-ownership projects (procedures and timing in § 25.181–25.183) ; and (b) waiver/reduction requests tied to density bonuses under the local density-bonus rules (§ 25.38.7) where state law constraints apply .
Filing, referrals, required public hearing notice, and appeal opportunities are governed by the general application procedures in § 25.41 and associated public hearing rules (see references to § 25.43 for public hearing procedure) .

District-by-district snapshot (where variances/exceptions usually matter)

Below are the Fairfield zoning districts most relevant to variance/exception requests. Each subsection states the typical purpose, common permitted uses at a high level, the decision-relevant dimensional standards, and where the district commonly applies in the City. All dimensional figures below are drawn from the Zoning tables cited (see code references).

Notes: Where a numeric standard is quoted the underlying table is identified. Always verify parcel-specific requirements and any overlay (Hillside, Train Station Specific Plan, etc.) that may change standards. Verify with the jurisdiction.

RL (Low‑Density Residential)

Purpose: neighborhood single-family residential; neighborhood character protection. (See Table 25‑2.1.)
Typical permitted uses: single‑family homes and accessory uses listed by Table 25‑1 (residential uses) .
Key standards (Table 25‑2.1): Front setback to habitable portion 20 ft (varies by suffix), garage-facing street setback up to 35 ft for some RVL categories, max FAR commonly 0.5 for RL types; height limit typically 35 ft. See Table 25‑2.1.
Where it applies: established single‑family neighborhoods and areas identified on the zoning map; SB 9 rules noted where applicable.

RLM / RL with density suffixes (Medium‑Low Residential)

Purpose: smaller‑lot single‑family and townhome-style development where medium‑low density is desired. See Table 25‑3 and Table 25‑5 for small‑lot options.
Typical permitted uses: single‑family detached, attached small-lot homes, accessory uses per Table 25‑1.
Key standards (Table 25‑3 / 25‑5): Front setback to habitable portion commonly 15 ft, interior side yard minimum 5 ft, rear yard typically 15–20 ft, max FAR 0.5, max height 35 ft for main dwelling. Parking ratios and open space rules vary by small‑lot table.

RM (Medium‑Density Residential)

Purpose: multifamily development (apartments, townhomes) at medium density. See Table 25‑4.
Typical permitted uses: multifamily dwelling units, accessory uses listed in Table 25‑1.
Key standards (Table 25‑4): Density generally 10–18 du/acre, setbacks to habitable portions 15–20 ft average / 15 ft min from street front, building height commonly 35 ft, private open space and common open space percentages specified per table.

RH / RVH (High‑Density Residential)

Purpose: higher-density multifamily and mixed‑form residential. See Table 25‑4.
Typical permitted uses: multifamily, live/work where allowed, accessory services.
Key standards: Density up to 19–25 du/acre for RH and 26–40 du/acre for RVH, height allowances up to 45–50 ft (Table 25‑4), larger common open space requirements. Increases in height or FAR may require a Conditional Use Permit (see § 25.40.6 referenced in notes).

CN / CM / HD (Neighborhood & Community Commercial, Heart of Fairfield)

Purpose: neighborhood commercial (CN), community/mixed‑use (CM), and downtown/heart district (HD). See the development standards and allowed uses referenced in the Specific Plan and Table 25 series.
Typical permitted uses: retail, eating/drinking establishments, offices (subject to restrictions in adjacent residential areas), mixed‑use residential above retail in some districts. Specific uses for the South Lake Activity Core are called out in the Train Station Specific Plan.
Key standards (consolidated site table): front setbacks vary 10–25 ft, building heights often 35–55 ft depending on subdistrict, and FAR values appear in district tables (see consolidated Tables). Parking and signage have their own rules and separate Exception/Sign Exception processes.

REC / PF / AG / OSC (Parks, Public Facilities, Agriculture)

Purpose: parks/open space (REC), public facilities (PF), agriculture (AG), open space conservation (OSC). See Table 25‑14 for Agriculture/Public Benefit zones.
Typical permitted uses: parks, schools, civic uses, agricultural uses depending on designation.
Key standards (Table 25‑14): front/street side yards commonly 20–25 ft, building heights up to 50 ft in some public/AG districts, landscape requirements differ. Exceptions for special site conditions may be granted by the Commission under § 25.158.

What a Variance can and cannot do (quick table)

Request type	What it may change	Decision body	Key findings required	Code Reference
Variance	Dimensional standards (setbacks, heights, coverage, parking dimensions/number, lot area) — not uses or density	Director or Planning Commission (after hearing); appealable	Unique property circumstances cause denial of privileges to owner; necessary for preservation/enjoyment of property rights; not detrimental to public health/safety/welfare	§ 25.40.8
Subdivision Exception (Article / map exceptions)	Design standards for subdivisions where literal application is impractical	Planning Commission	No special privilege; special circumstances; carries out spirit/intent of ordinance	§ 25.158
Waiver (common ownership / tentative maps)	Substitute standards for common‑ownership projects; waiver timing rules tied to tentative map	Planning Commission (appealable to City Council)	Financial hardship disproportionate to public benefit OR necessary to preserve design features (open space/recreation)	§ 25.181–25.183
Density‑bonus Waiver/Reduction	Waiver/reduction of standards that physically preclude construction of the density bonus project	City (per rules), subject to state law limits	City must approve unless specific adverse impacts or conflicts with state/federal law exist	§ 25.38.7
Sign Exception	Deviations in sign size or height (minor or major exceptions capped by %)	Zoning Administrator (minor) or Planning Commission (major)	Limited to deviations from sign standards; cannot permit otherwise prohibited signs	Sign Article (Chapter 25, Art. IX) and sign exception rules in § 25.1306–25.1309

How decisions are made — required findings and process highlights

The applicant files in compliance with § 25.41 (application filing, processing) and the Director will hold or refer the matter to the Planning Commission where warranted; public hearing procedures are in § 25.43 (notice and hearing) .
A written decision with findings is required; variances must comply with State Government Code 65906 and the local findings listed in § 25.40.8.C (three required findings) .
Conditions may be imposed to avoid granting special privileges inconsistent with the neighborhood (explicitly allowed in the variance and exception rules) § 25.40.8 and § 25.158 .
For subdivision-related waivers, timing matters: applications for a waiver must generally be filed and decided prior to filing the tentative map unless the tentative map includes a waiver of certain Subdivision Map Act time limits (§ 25.182) .
Sign-related deviations are handled through the Sign Exception process in the Sign Article rather than through the general Variance article — check § 25.1306–25.1309 (Sign exceptions and thresholds) .

Checklist — what an applicant must satisfy (practical)

File application in accordance with § 25.41 (forms, fees, materials) and include the fee(s) and full project drawings .
Demonstrate unique circumstances of the parcel (size, shape, topography, location, surroundings) tied to the requested deviation per § 25.40.8.C.1 .
Show the variance is necessary to preserve/enjoy substantial property rights consistent with neighbors in the same district (§ 25.40.8.C.2) .
Demonstrate the variance won’t injure public health/safety/welfare or nearby properties (§ 25.40.8.C.3) .
Provide evidence that requested change is limited to development standards (not a request to change permitted uses or density) per § 25.40.8.A .
If the request involves a subdivision or common ownership waiver, include the subdivision-specific justification and fees and file prior to the tentative map per § 25.181–25.183 and § 25.182 .
For density‑bonus projects requesting waivers/reductions, include documentation showing the waiver is physically necessary and address the state law limitations referenced in § 25.38.7 .
Anticipate public notice/hearings (Director/Commission) and prepare to address neighborhood impacts per § 25.43 and appealability under the local appeal rules (appeals to City Council) .
If signage is at issue, pursue the Sign Exception process instead of a general variance; follow § 25.1306–25.1309 .

Risks & Ambiguities

Issue	Why it matters	What to verify
Variance cannot change uses or densities	Applicants sometimes request a variance to allow a use rather than a dimensional change; the ordinance disallows this	Confirm whether your request is strictly for a development standard; uses/density require rezone or Conditional Use Permit. See § 25.40.8.A
Sign standards handled separately	Sign exceptions have their own thresholds (10% minor, 20% major) and procedures	If the request is sign-related use the Sign Exception rules in Chapter 25, Art. IX (e.g., § 25.1306–25.1309)
Subdivision timing for waivers	For common‑ownership waivers and many subdivision exceptions, timing is critical (before tentative map)	File waiver requests before tentative map or include required waiver of Subdivision Map Act time limits per § 25.182 and § 25.181
State law limits on density bonus waivers	State statutes may override local discretion for density bonus concessions/waivers	For density bonus projects follow the standards and the exceptions list in § 25.38.7; check applicable Government Code references cited there
Parcel/overlay-specific standards can change the analysis	Overlays (Hillside, Train Station Specific Plan, Historic) add requirements or change applicable tables	Identify overlays on the parcel (Train Station Specific Plan references Tables 25‑3–25‑5, etc.) and verify which table/notes apply; Verify with the jurisdiction
Incomplete application = referral/denial delay	Missing technical studies or incorrect fee can delay processing	Follow § 25.41 application submittal checklist and include CEQA, geotechnical, or covenant materials when required

Plain-English Summary

If your property’s shape, slope, or size makes the City’s setback, height, parking, or lot‑size rules impossible or unfair compared with your neighbors, you can apply for a Variance to relax those development standards (not the allowed uses). The Planning Director or Planning Commission decides after a public hearing and must make written findings showing the situation is unique, the change is necessary to protect your property rights, and it won’t harm the neighborhood (see § 25.40.8) .

Frequently asked questions

What is a Variance in Fairfield and where is it in the code?

A Variance in Fairfield allows discretionary relief from development standards (setbacks, heights, lot area, parking dimensions, etc.) but not from permitted uses or densities. The variance rules and the permitted scope are in § 25.40.8 and the required findings are in § 25.40.8.C .

Who decides a Variance application in Fairfield?

The Planning Director initially reviews and holds the hearing; the Director may refer the matter to the Planning Commission if warranted. The Planning Commission can grant or deny variances; decisions are recorded in writing and are appealable under the Code’s appeal rules. See § 25.40.8 and the application process § 25.41 .

What findings must I prove to get a Variance?

You must show (1) unique property circumstances (size/shape/topography/location/surroundings) that make strict application deny privileges enjoyed by neighbors; (2) the variance is necessary to preserve substantial property rights consistent with others in the district; and (3) the variance won’t harm public health, safety, or welfare. These three findings are listed in § 25.40.8.C .

Can a Variance let me build a use that is otherwise not allowed (e.g., a business in R‑1)?

No. Variances are limited to development standard deviations; they cannot be used to authorize a land use or residential density otherwise prohibited by the ordinance. If you want a new use you must pursue the appropriate permit or rezoning. See § 25.40.8.A .

What is an Exception under the subdivision rules and how is it different?

An Exception (for subdivision/design standards) allows the Planning Commission to deviate from specific subdivision design standards where literal compliance is impossible, provided conditions are attached to avoid special privileges and the exception carries out the ordinance’s intent. See § 25.158 .

If I have a tentative map, when must I apply for a waiver or exception?

Applications for a waiver or for any variance/use permit associated with a common ownership project should be filed and decided before the tentative map is filed, unless the tentative map includes a waiver of certain Subdivision Map Act timing limits; see § 25.182 and § 25.181–25.183 for timing and procedural details .

Do sign requests use the same Variance process?

No. Sign deviations are handled through the Sign Exception process within the Sign Article (Chapter 25, Article IX). Minor Exceptions (up to 10%) can be approved by the Zoning Administrator; Exceptions up to 20% require Planning Commission review. See the Sign Exception rules § 25.1306–25.1309 .

Can density‑bonus projects request waivers of standards in Fairfield?

Yes; the city’s density‑bonus rules allow applicants to request waivers or reductions of development standards that would physically preclude the bonus project. The City must approve such waivers unless specific adverse impacts or conflicts with law exist. See § 25.38.7 (and note state law interplay) .

What tables list the setback and height numbers I’ll be measured against?

Residential and other district development standards are in the zoning tables: Table 25‑2.1 (RVL/RL), Table 25‑3 (RL/RLM), Table 25‑4 (multifamily RLM/RM/RH/RVH), and Table 25‑14 (AG/OSC/REC/PF). Refer to these tables for front, side and rear setbacks, maximum FAR and heights. See Table citations in the ordinance (Tables 25‑2.1, 25‑3, 25‑4, 25‑14) .

If my lot is in a Specific Plan or Overlay, do different rules apply?

Yes. Specific Plans and overlays (e.g., Train Station Specific Plan, Hillside Overlay) reference and sometimes modify the base tables and standards; the Specific Plan text often directs which Table or standard applies (see Train Station Specific Plan references to Tables 25‑3–25‑5). Verify the applicable overlays for your parcel and follow their modified standards — Verify with the jurisdiction .
