Understanding Variances and Special Use Permits in Zoning

Variances and special use permits are two of the most common zoning actions discussed in council meetings — and they are often overlooked by investors who focus exclusively on rezoning. Understanding these tools can reveal development opportunities that others miss and provide early signals about where market pressure is building.

What Is a Variance?

A variance is an exception to an existing zoning rule granted by a municipal board (typically a Board of Adjustment or Board of Zoning Appeals). Variances allow property owners to deviate from specific zoning standards — such as setback requirements, building height limits, or parking minimums — without changing the underlying zoning classification.

The legal standard for a variance typically requires the applicant to demonstrate a hardship unique to the property. This means the variance is necessary because of the property's physical characteristics (irregular lot shape, topography, or other conditions) — not simply because the owner wants to build something bigger or more profitable. This hardship requirement is what distinguishes variances from rezonings.

Common Types of Variances

• Height variances: Allow buildings taller than the zone permits. Frequently requested in urban infill situations where surrounding buildings already exceed the current height limit.
• Setback variances: Allow buildings closer to property lines than the code requires. Common on irregular lots or in older neighborhoods where the zoning code was adopted after existing structures were built.
• Parking variances: Reduce the number of required parking spaces. Increasingly common in urban areas and near transit, where municipalities are recognizing that older parking standards overestimate demand.
• Lot coverage variances: Allow more of the lot to be covered by structures. Frequently requested for additions to existing buildings.
• Use variances: Allow a use not typically permitted in the zone. These are rare, harder to obtain, and treated almost like a rezoning by most boards. Some jurisdictions do not allow use variances at all.

What Is a Special Use Permit?

A special use permit (also called a conditional use permit in many jurisdictions) allows a specific use that is permitted in a zone but only with additional review and conditions. Unlike variances, special use permits do not require proving hardship — they are anticipated uses that need extra oversight because of their potential impact on surrounding properties.

The zoning code lists which uses require a special use permit in each zoning district. The review process evaluates whether the specific proposal — its design, traffic impact, hours of operation, and other characteristics — is compatible with the surrounding area.

Examples of Uses Requiring Special Use Permits

• Medical facilities and hospitals
• Schools and religious institutions
• Drive-through restaurants
• Gas stations and convenience stores
• Large retail establishments (big-box stores)
• Data centers and telecommunications facilities
• Multifamily housing in certain residential zones
• Outdoor dining and entertainment venues

Why These Are Important Market Signals

Variance Patterns Indicate Market Pressure

When multiple height variances are granted in a submarket, it signals that the existing zoning is too restrictive for current market demand. Developers are willing to pay the legal fees and go through the hearing process because the economics justify taller buildings — even with the extra cost and uncertainty. This pattern often precedes a broader rezoning or upzoning initiative, as the planning department recognizes that the zoning code no longer reflects market reality.

For example, if you see three height variances approved on the same commercial corridor within a 12-month period, the planning department is likely already discussing whether to update the height limits for that entire corridor. The investors who acquired properties along that corridor before the upzoning captured significant value.

Special Use Permits Signal New Demand Drivers

A special use permit for a hospital or university campus brings employment, foot traffic, and economic activity that affects surrounding property values significantly. Similarly, a cluster of special use permits for restaurants and entertainment venues signals a neighborhood transitioning into a dining and nightlife district.

The conditions attached to special use permits also reveal municipal priorities. If the board requires enhanced landscaping, noise mitigation, or traffic improvements, those conditions tell you what the municipality values — and where future applications may face scrutiny.

The Application Process

Variance Application Process

Step 1 — Pre-Application Conference: Most jurisdictions offer (or require) a meeting with planning staff before formal submission. Staff will advise on the likelihood of approval and any concerns to address.

Step 2 — Application Submission: The applicant submits a variance application with the property survey, site plan, description of the requested deviation, and a hardship statement explaining why the variance is necessary.

Step 3 — Staff Review: Planning staff reviews the application against the zoning code and prepares a staff report with a recommendation. This review typically takes 2 to 4 weeks.

Step 4 — Public Notice: The jurisdiction sends mail notice to neighboring property owners (typically within 300 to 500 feet) and may require a sign posted on the property.

Step 5 — Board of Adjustment Hearing: The case is heard at a Board of Adjustment (or Board of Zoning Appeals) meeting. The applicant presents, staff presents the recommendation, and the public provides testimony. The board votes to approve, approve with conditions, or deny.

Step 6 — Decision and Appeals: The board's decision is typically final unless appealed to the city council or a court. The entire process from application to decision usually takes 1 to 3 months.

Special Use Permit Application Process

The special use permit process is similar but often involves more review bodies:

Step 1 — Application Submission: The applicant submits an application including a detailed site plan, traffic study (if required), and a narrative explaining the proposed use and how it meets the special use permit criteria.

Step 2 — Staff Review: Planning staff evaluates the application against the specific criteria for the requested use, which are defined in the zoning code. Staff also coordinates review with other departments (transportation, fire, utilities).

Step 3 — Planning Commission Review: Unlike variances, special use permits often go to the Planning Commission for a recommendation before the final decision-making body.

Step 4 — Public Hearing: The case is heard before the Board of Adjustment, Planning Commission, or City Council (varies by jurisdiction). Conditions of approval are discussed and attached.

Step 5 — Decision with Conditions: Special use permits are almost always approved with conditions — hours of operation, traffic mitigation, landscaping requirements, lighting standards, and periodic review dates. These conditions are binding and run with the permit.

Variance vs. Rezoning: When to Use Which

Understanding when a property owner would seek a variance versus a rezoning is critical for interpreting the market signals correctly.

| Factor | Variance | Rezoning | |---|---|---| | What changes | Exception to a specific rule (height, setback, parking) | The zoning classification itself | | Legal standard | Must prove hardship unique to the property | Must demonstrate consistency with comprehensive plan | | Scope | Applies to one property, one specific deviation | Changes all permitted uses and standards for the parcel | | Decision body | Board of Adjustment / Board of Zoning Appeals | Planning Commission recommendation, City Council final vote | | Timeline | 1 to 3 months | 2 to 6 months | | Market signal | Developer pushing the limits of current zoning | Developer needs fundamentally different use or density |

When a variance is the right tool: The property owner wants to build something that is essentially consistent with the zoning but needs a minor adjustment — for example, a 5-foot reduction in a side setback to accommodate an addition, or an extra 10 feet of building height to make a project economically viable.

When rezoning is the right tool: The property owner wants to do something fundamentally different from what the current zoning allows — convert agricultural land to commercial use, change single-family residential to multifamily, or shift from residential to mixed-use. If the entire use needs to change, a variance will not accomplish that (except in the rare jurisdictions that allow use variances).

For investors, the distinction matters because rezoning signals a fundamental change in a parcel's trajectory, while a variance signals that the current zoning is close to what the market demands but not quite flexible enough. Both are actionable, but they indicate different levels of market transformation.

Tracking Variances and SUPs in Council Meetings

Variances and special use permits are discussed in Board of Adjustment and Planning Commission meetings. Key signals to monitor:

• Frequency: Multiple variances in one area suggest the zoning code is outdated for that submarket
• Type: Height and density variances signal development pressure; setback variances may indicate infill activity
• Staff recommendations: Approval recommendations indicate alignment with planning goals. Denial recommendations that are overridden by the board suggest political support for development.
• Conditions imposed: The conditions attached to permits reveal municipal priorities and set precedents for future applications
• Denial patterns: Areas where variances are consistently denied may face regulatory headwinds that affect investment returns

County Examples: Where to Track Variance and SUP Activity

Variance and special use permit processes vary by jurisdiction. Here are some of the most active markets:

• Miami-Dade County (FL) — High variance volume driven by dense urban development and older zoning codes. The county's Board of Adjustment handles a heavy caseload. Track activity via Miami-Dade County meetings.
• Fulton County (GA) — Atlanta's core county sees frequent special use permit applications for commercial and mixed-use development along the BeltLine and in Midtown. See Fulton County meetings.
• Nashville-Davidson County (TN) — Nashville's growth has generated significant variance activity, particularly height and density variances in the urban core and suburban centers. Monitor via Nashville-Davidson County meetings.
• Mecklenburg County (NC) — Charlotte's rapid development drives both variance requests and special use permits for large-scale projects along the light rail corridor. Check Mecklenburg County meetings.
• Clark County (NV) — Las Vegas area development generates consistent special use permit activity for gaming, entertainment, and commercial uses. See Clark County meetings.
• Hillsborough County (FL) — Tampa's Board of Adjustment processes a high volume of variance and special use permit cases, especially in redeveloping corridors. Track via Hillsborough County meetings.
• Maricopa County (AZ) — Phoenix metro variance and SUP activity is concentrated in rapidly growing suburban areas along major freeway corridors. Monitor Maricopa County meetings.
• Bexar County (TX) — San Antonio's Board of Adjustment handles variance applications across the city's diverse zoning districts. See Bexar County meetings.

Frequently Asked Questions

What is the difference between a variance and a special use permit?

A variance is an exception to a specific zoning standard (such as setback, height, or parking requirements) granted due to a hardship unique to the property. A special use permit allows a use that is permitted in the zone but requires additional review and conditions. Variances modify the rules for a specific property; special use permits authorize a use that the zoning code already contemplates but wants to regulate more closely.

How long does it take to get a zoning variance?

A zoning variance typically takes 1 to 3 months from application to decision. The process involves submitting an application, a staff review period, public notice, and a hearing before the Board of Adjustment or Board of Zoning Appeals. Simple variances with staff support may be approved in a single hearing, while contested cases can take longer due to deferrals or appeals.

Can a variance be denied?

Yes, a variance can be denied. Common reasons for denial include failure to demonstrate a hardship unique to the property, opposition from neighboring property owners, inconsistency with the comprehensive plan, and a finding that the variance would negatively affect surrounding properties. Denial rates vary by jurisdiction but typically range from 10% to 30% of applications.
