Norco — Variances and Exceptions

Last reviewed: July 2, 2026

Overview

Variances in Norco are governed by the City's Zoning Ordinance (Title 18). A variance is an authorized departure from a numeric or dimensional zoning standard where special circumstances make strict application impractical; the Planning Commission (or Council on appeal) is the primary decision body. Some local chapters explicitly disallow variances for specific regimes (notably certain accessory-building / ADU rules). See the city's variance criteria and required findings at § 18.44.16 and the procedural rules in § 18.44.08 and § 18.44.12.

This page summarizes exactly what Norco's code says about variances and related exceptions, shows how those rules interact with specific zones and overlays, and points to the exact sections you must rely on when preparing an application.

(First mentions of related planning topics — Norco's code and city guides — are linked: see Norco Zoning and the city's pages on development standards, parking, design review, overlay districts, ADUs, and the California Building Standards Code for building permitting details.)

What the Norco code actually requires (key rules)

• Variance purpose and scope: a variance exists to address "exceptional narrowness, shallowness, unusual shape, or exceptional topographic or other condition" of a parcel that causes practical difficulty or undue hardship under the ordinance's literal terms. See § 18.44.02.

• Limitations (what a variance cannot do): a variance cannot authorize a use not permitted by the base zone, nor grant special privileges inconsistent with other properties in the vicinity. See § 18.44.04.

• Initiation and application: a variance may be initiated by the owner (verified application) or by motion of the Planning Commission or City Council; applications must use the Planning Department form and include the items listed in § 18.44.08 (owner info, fee, nine copies of site plan meeting § 18.40.08 site-plan content, and any additional studies requested). See § 18.44.06 and § 18.44.08.

• Procedural steps and review: variance applications are reviewed concurrently with Site Plan Review and, if applicable, Architectural Review; public hearings and appeals follow the hearings/appeals chapter. See § 18.44.12 and § 18.44.14.

• Required findings to grant a variance: the approving body must find that because of special circumstances applicable to the property (size, shape, topography, location, surroundings), strict enforcement deprives the property of privileges enjoyed by other similar properties; and that conditions can be imposed to avoid special privileges or adverse impacts. See § 18.44.16 and § 18.44.18.

• Conditions, force, and revocation: conditions of approval (right-of-way dedication, architecture, height, parking, etc.) may be imposed and must be complied with; failure or discontinuation for one year may trigger revocation procedures under Chapter 18.46. See § 18.44.18, § 18.44.20, and § 18.44.28.

• Reapplication timing: after a denial, the City will not accept a new, similar variance application for the same property for 12 months unless the denial expressly allows earlier re-filing. See § 18.44.26.

• Expiration: a granted variance must be "used" (substantial construction begun, occupancy, or map recording) within two years (conditions may shorten/extend up to five years maximum) — see § 18.46.08.

• Overlay / special programs with separate rules: some programs provide administrative waivers or require different findings (for example, density-bonus waiver/ reduction rules in Chapter 18.65, § 18.65.12 — a waiver/reduction of development standards for bonus projects is mandatory unless specific adverse impacts exist). See § 18.65.12.

• Explicit no-variance areas: the code text for accessory dwelling units and certain accessory-building permits includes express language that no variance or exemption from that section's requirements will be granted. The ADU/junior-ADU rules state "Notwithstanding Chapter 18.44, there shall be no variance or exemption granted from the requirements contained in this section." The ADU rules and accessory-building permit chapter provide many objective ADU standards and ministerial review triggers (ADU ministerial approval provisions and parking exceptions are spelled out). See the ADU provisions (ADU development requirements and the quoted no-variance language are present in the ADU text found in the code excerpts).

  • Exact section number for the specific "no variance" sentence as printed in the ordinance excerpts is contained within the ADU text in the uploaded materials; if you need the exact numeric § printed in the ordinance framing (for example for legal filing), verify the exact subsection on the official Norco Municipal Code page or with the Planning Department (see "Information Gaps" below).

District-by-district breakdown (how variance practice interacts with specific Norco zones)

Below are the Norco districts for which the code text is explicit about development standards or where the code names special procedures that affect variance outcomes. Each district subsection lists purpose (per the code), typical permitted uses, key dimensional standards referenced in the ordinance, and where the district applies in the code.

A-1 (Agricultural, Chapter 18.13)

• Purpose: preserve Norco's low-density agricultural and animal-keeping character and establish animal-keeping standards. The code repeatedly references Chapter 18.13 for animal/unit definitions and rules. § 18.13.06 contains animal-keeping definitions and limits referenced elsewhere.
• Typical permitted uses: agricultural, single-family with animal-keeping consistent with A-1 rules (see animal-unit tables).
• Key standards (examples cited elsewhere in code): animal-unit minimums and setbacks; standards for driveways, PAKA recording, and open-animal-area preservation when accessory units are proposed. See animal-keeping cross-references in § 18.13.06 and related AKO rules in § 18.16.50.
• Where it applies in the variance context: variances cannot create uses not allowed in the A-1 zone (per § 18.44.04); animal-keeping specifics are enforced via the zone chapters and may limit variance remedies.

R-1-10 and R-1 family (single-family residential; see Chapter 18.16 and related R chapters)

• Purpose: low-density single-family residential focus with optional Animal-Keeping Overlay (AKO) designations. § 18.16.50 lists AKO animal-keeping standards (max animal units by lot size, separation distances, adjacency to horse trails).
• Typical permitted uses: single-family dwellings; accessory uses consistent with underlying zone and animal-keeping rules.
• Key dimensional standards: where applicable the R-1-10 specifics and AKO add rules for setbacks, minimum lot sizes, and animal area requirements; see zone chapters for numeric setbacks/heights. Variances that seek relief from R-1 dimensional rules must meet the variance findings § 18.44.16.

R-3 (Low-density multiple-family; Chapter 18.17)

• Purpose: permit low-density multifamily living that fits Norco's rural/outdoor orientation; see § 18.17.02.
• Typical uses: small multifamily buildings consistent with neighborhood character.
• Dimensional standards: see Chapter 18.17 (height, coverage, spacing). Variances from those numeric standards require the findings in § 18.44.16.

C-G (Commercial General; Chapter 18.29)

• Purpose: general commercial uses with site-plan review and performance/screening standards. § 18.29.30 and Table of Development Standards summarize site-specific requirements (minimum lot size, setbacks, height up to 35 ft typical).
• Typical uses: broad range of commercial and service uses; some uses need Conditional Use Permits.
• Dimensional standards: see Table 2 in Chapter 18.29 (minimum lot size 13,125 sq ft, building setbacks like 25 ft street side, maximum height 35 ft, etc.); zone also requires landscaping and off-street parking per Chapter 18.38. Variances to these standards are processed under Chapter 18.44 and must meet its findings.

M (Industrial, e.g., M-2; Chapter 18.25)

• Purpose: industrial/manufacturing uses with separation and screening expectations. See Chapter 18.25 for permitted uses and § 18.25.16 for yard and height rules.
• Typical uses: light and heavy manufacturing, warehousing; service stations and other special uses have their own subrules (see Chapter 18.33).
• Dimensional standards: heights typically limited to two stories or 35 ft; separation and screening rules apply where abutting residential zones. A variance to height or setback in an M zone must satisfy § 18.44.16.

HS (Hillside/Preservation; Chapter 18.26)

• Purpose: manage hillside development with reduced street widths and grading controls; see § 18.26.16 for HS development standards.
• Typical uses: lower-intensity residential and preservation-oriented development per the HS chapter.
• Dimensional standards: specific on-site and off-site standards (e.g., front yard 25 ft, rear yard 30 ft, heights 35 ft, lot coverage limits like 15% in some HS subareas) and street-width exceptions. Variances to these numerical HS standards are reviewed under Chapter 18.44 and must meet § 18.44.16 findings.

HDO (Housing Development Overlay; Chapter 18.64)

• Purpose: facilitate affordable housing via an overlay with site-specific objective standards. HDO projects may use ministerial approvals if objective standards and affordability thresholds are met. See § 18.64.02 – § 18.64.08.
• Effect on variances: Chapter 18.65 (density bonus and waivers) interacts with HDO projects—waivers or reductions of development standards for density-bonus projects are governed by § 18.65.12 and related density-bonus rules; the approval authority must follow the findings in § 18.65.12 when considering waivers.

Checklist — what an applicant must satisfy when preparing a variance application in Norco

• Demonstrate owner authorization / owner-signed application and provide legal parcel description (required by § 18.44.08).
• Pay the nonrefundable application fee (fee schedule per City Council resolution) (§ 18.44.08).
• Provide nine (9) copies of a full Site Plan meeting § 18.40.08 content (plans must enable concurrent Site Plan Review / Architectural Review where required) (§ 18.44.08; § 18.44.12).
• Prepare written evidence meeting the variance findings: parcel special circumstances, deprivation of privileges compared to similar properties, and proposed measures to avoid special privileges (§ 18.44.16).
• Be ready to accept and document conditions the Commission may impose (parking, right-of-way dedications, architecture, limits on duration) (§ 18.44.18).
• If applying on an ADU or accessory-building matter: check the ADU / accessory-building chapter for mandatory ministerial standards and "no variance" language; ADU applications may be ministerial — do not assume variance relief is available (see ADU text for the specific "notwithstanding" rule). Verify the exact subsection with staff.
• Expect public notice and hearing schedule per the Site Plan/Appeals chapters (§ 18.40.13, § 18.43) and plan for neighbor outreach.

Risks & Ambiguities

Plain‑English summary

If your Norco property has a unique physical condition making a code rule infeasible (narrow, oddly shaped, steep, etc.), you can apply for a variance — but you must show the Planning Commission that the problem is parcel-specific, that other similar parcels don’t have the same limitation, and that your change won’t give you an unfair special privilege; the rules and required findings are in § 18.44.16 and the application steps are in § 18.44.08. Some topics (notably many ADU rules and accessory‑building limits) explicitly cannot be changed by variance — check the ADU/accessory sections carefully and verify any ambiguous subsection numbers with the Planning Department before you file.
