3.3 Variances, Special Exceptions & Conditional Use Permits

3.3 Variances, Special Exceptions & Conditional Use Permits

Uniform zoning rules cannot anticipate every physical peculiarity of individual land parcels. To prevent unconstitutional regulatory takings and accommodate community-serving uses, the law provides administrative release mechanisms. The zoning inspector must master the sharp distinctions between Variances, Conditional Use Permits (Special Exceptions), and Legislative Rezoning, ensuring that quasi-judicial decisions remain strictly within statutory bounds and that approved conditions are enforced in the field.

Distinguishing Administrative Zoning Relief

Each administrative mechanism operates under a distinct legal standard, is adjudicated by a specific body, and yields distinct legal results:

Variances: Area vs. Use Variances

A variance authorizes deviation from literal code requirements, divided into two distinct statutory classes:

1. Area (Dimensional) Variances

An area variance provides relief from physical or bulk dimensions, such as relaxing setbacks, increasing maximum building height, expanding allowable lot coverage, or reducing required parking stalls. Area variances are adjudicated under the standard of unnecessary hardship or practical difficulty.

2. Use Variances and Statutory Prohibitions

A use variance permits a land use strictly barred in the zoning district (e.g., operating an auto salvage yard in a residential zone).

[!WARNING] Prohibition of Use Variances: IZC Section 106.8 (Use variance) — numbered § 107.8 in the 2015 edition and § 108.8 in the 2021/2024 editions — provides that the board of adjustment shall not grant a variance to allow the establishment of a use in a zoning district when such use is prohibited by the provisions of this code. Together with state enabling statutes in many jurisdictions, the Board of Adjustment is strictly prohibited from granting use variances. Authorizing an unpermitted use usurps the exclusive legislative rezoning authority of the elected City Council. Where permitted by state law, use variances require proving total deprivation of all beneficial economic utility.

The Legal Standard of "Unnecessary Hardship"

IZC Section 106.7.3 (Variance review criteria) — § 107.7.3 in the 2015 edition — lists eight criteria that every variance request must be consistent with: (1) limitations on use of the property due to physical, topographical and geologic features; (2) no special privilege granted to the owner; (3) without a variance there can be no reasonable use of the property; (4) the grant is not based solely on economic reasons; (5) the necessity was not created by the property owner; (6) the variance is the minimum necessary for reasonable use; (7) the grant will not be injurious to public health, safety or welfare; and (8) the property possesses one or more unique characteristics generally not applicable to similarly situated properties. Local ordinances and the SSZEA compress those eight into the following five practical prongs, and the Board must make affirmative written findings on each:

1. Unique Physical Land Conditions: The hardship arises strictly from physical parcel features—exceptional narrowness, shallow depth, steep slopes, rock ledges, or wetlands—preventing compliant construction.
2. Not Common to Neighborhood: The physical obstacle is peculiar to the subject lot and not shared generally across the district. (If widespread, the proper remedy is a legislative zoning amendment).
3. Hardship Not Self-Created: The owner or predecessors did not create the problem (e.g., creating substandard lots, building without permits, or buying with knowledge of restrictions to seek speculative profit).
4. Neighborhood Character Preserved: The variance will not impair adjacent property development, devalue surrounding properties, or harm public safety.
5. Minimum Variance Necessary: Relief granted must be the absolute minimum necessary to allow reasonable property use.

[!IMPORTANT] The Financial Hardship Rule: Personal financial loss, construction cost increases, or inability to achieve maximum economic return never constitutes unnecessary hardship. Personal medical issues, expanding family sizes, or convenience are personal circumstances, not physical land hardships.

Conditional Use Permits (CUP) & Special Exceptions

A Conditional Use Permit (CUP) governs land uses that are desirable in the community, but possess operational characteristics (traffic, noise, outdoor lighting) requiring site-specific oversight (e.g., churches, daycares, gas stations, utility substations).

Standards of Review

Unlike variances, a CUP does not require showing hardship. The board reviews the application against two codified tiers:

• General Criteria: Harmony with the comprehensive plan, infrastructure adequacy (water, sewer, roads), and public health protection.
• Specific Criteria: Codified standards (e.g., minimum 100 sq. ft. of play area per child in a daycare, 15-foot landscape buffers, dedicated stacking lanes).

If an applicant demonstrates that all objective general and specific criteria are met, the board cannot arbitrarily deny the permit, but may attach reasonable conditions.

The Board of Adjustment: Quasi-Judicial Procedures

The Board of Adjustment operates as an administrative court of limited jurisdiction and must enforce procedural due process:

• Public Notice: Newspaper publication, on-site posting, and mailings within a statutory radius (typically 200–500 feet).
• Sworn Testimony: Witnesses must testify under oath; parties retain rights to cross-examine; verbatim records are maintained.
• Ban on Ex Parte Contacts: Private off-the-record discussions between board members and parties are prohibited.
• Written Findings of Fact: Decisions must include written findings explaining how record evidence satisfies statutory criteria.

Enforceable Conditions of Approval

The board may attach reasonable, nexus-based conditions to mitigate external impacts: opaque masonry screening walls, vegetative landscape buffers, restricted delivery hours, and full-cutoff exterior lighting.

---

Compliance Inspections and Revocation Protocols

Variances and CUPs run with the land, binding future owners. Prior to Certificate of Occupancy sign-off, the inspector verifies:

1. Setback Verification: Field-measuring actual building setbacks with a calibrated laser device to ensure construction matches the granted variance.
2. Buffer and Screening Installation: Verifying opaque fences, retaining walls, and specified plant materials match approved landscape plans.
3. Lighting Cutoff Verification: Confirming exterior fixtures prevent light trespass (typically < 0.5 foot-candles at property lines).
4. Revocation for Noncompliance: Violating approved conditions constitutes a zoning violation. The inspector issues a Notice of Violation; uncorrected violations proceed to a formal Board of Adjustment revocation hearing.
