Rezoning vs. Variance: What's the Difference?

What Is a Variance?

A variance is an administrative relief from the dimensional standards of a zoning ordinance — not from the use requirements. Common examples of dimensional standards that variances address:

Setback requirements (e.g., the building is 10 feet from the property line, but 15 feet is required) Height limits (e.g., the building is 45 feet tall, but the zone caps at 40 feet) Lot coverage maximums (e.g., 60% of the lot is covered by impervious surface, but 55% is the limit) Minimum lot size (e.g., the parcel is 0.45 acres, but 0.5 acres is the minimum) Parking requirements (e.g., 18 spaces are provided, but 22 are required)

What a variance cannot do: A variance cannot authorize a use that is not permitted in the zone. If your intended use is prohibited in the current zone, a variance cannot help — you need a rezoning or a conditional use permit.

How Variances Are Granted

Variances are typically granted by the Zoning Board of Appeals (ZBA) — or a similarly named quasi-judicial body — based on a hardship standard. The applicant must demonstrate:

1. Unique hardship: The dimensional standard creates a hardship specific to this property (not a general hardship shared by all properties in the area). Hardship typically means the property cannot be reasonably developed without the variance due to unique physical characteristics — irregular shape, topography, existing easements, etc.

2. Not self-created: The hardship was not created by the applicant. If you bought an undersized lot knowing it was undersized, most boards will not grant a variance.

3. Not contrary to the general purpose of the code: Granting the variance won't undermine the intent of the zoning code or harm the surrounding neighborhood.

Variance hearings are quasi-judicial — neighbors can testify for or against, and the board's decision can typically be appealed to the courts. Variances tend to be granted for modest dimensional relief and denied when the requested deviation is substantial.

What Is a Rezoning?

A rezoning (also called a zoning map amendment or legislative rezoning) changes the zoning designation of a specific parcel — moving it from one zone to another. Unlike a variance, which provides relief from dimensional standards within the existing zone, a rezoning fundamentally changes what uses are permitted on the property.

Examples: Rezoning land from Agricultural (AG) to Industrial (I-1) to permit a composting facility; rezoning a parcel from Commercial (C-2) to Mixed Use (MU) to permit residential apartments above ground-floor retail.

Rezonings are legislative acts — approved by the governing body (city council, county commission, board of supervisors) rather than a quasi-judicial board. This has important implications: elected officials are directly accountable to voters, meaning organized neighborhood opposition carries significant political weight.

The Rezoning Process

A typical rezoning process follows these steps:

1. Pre-application meeting: Meet with planning staff to discuss the proposal and identify concerns. Many jurisdictions require this step.

2. Comprehensive plan consistency: Most jurisdictions require that rezonings be consistent with the local comprehensive plan (general plan, master plan). If the requested zone isn't supported by the comprehensive plan's future land use map, the rezoning may be denied — or the applicant may need to pursue a comprehensive plan amendment first (which adds 6–12 months).

3. Application and staff review: Planning staff prepares a written recommendation based on comprehensive plan consistency, compatibility with adjacent uses, infrastructure capacity, and other criteria.

4. Planning commission hearing: A public hearing before the planning commission, which makes a recommendation to the governing body.

5. Governing body vote: The city council or county commission makes the final decision by vote. In most states, an extraordinary majority (5 of 7, or 2/3 vote) is required to approve a rezoning over the written protest of adjacent property owners.

6. Appeal: In most jurisdictions, rezoning decisions can be challenged in court within a specified period (often 30 days).

Timeline and Cost Comparison

Variance: Timeline: 45–120 days from application to ZBA decision Cost: $500–$5,000 application fee; $5,000–$25,000 in professional fees (surveyor, attorney, engineer) Success rate: Relatively high for modest dimensional relief; lower for substantial deviations

Rezoning: Timeline: 4–24 months from application to governing body approval; up to 36+ months if a comprehensive plan amendment is required Cost: $1,000–$10,000+ application fee; $25,000–$150,000+ in professional fees (attorney, planner, traffic engineer, community engagement) Success rate: Highly variable; politically sensitive; major opposition can defeat a technically meritorious application

The bottom line: A variance is the faster, cheaper path — but it can only fix dimensional issues, not change what uses are permitted. If the intended use isn't permitted in the current zone, only a rezoning (or conditional use permit) can solve the problem.

Key Takeaways

• A variance provides relief from dimensional standards (setbacks, height, parking) — not from use restrictions.
• A rezoning changes the zoning designation itself — allowing uses that weren't previously permitted.
• Variances are quasi-judicial (ZBA); rezonings are legislative (city council/county commission).
• Rezonings are far more expensive and time-consuming — plan for 6–24 months minimum.
• A comprehensive plan amendment may be required before a rezoning — adding 6–12 additional months.
