When a property can't do what you want it to do under current zoning, there are two main paths to approval: rezoning and a variance. They're fundamentally different legal mechanisms, they go through different decision-makers, and they're appropriate for different problems. Choosing the wrong path wastes time and money — sometimes years of it.
What Rezoning Does
A rezoning changes the zoning classification of a parcel on the official zoning map. It's a legislative act— meaning it's decided by the elected governing body (city council, county board of supervisors, board of aldermen) after a formal public hearing process. When a rezoning is approved, the new classification permanently applies to the land, passes to future owners, and is reflected on the zoning map going forward.
Rezoning is the right path when your desired use simply isn't permitted in the current zone at all. If you want to build an apartment complex on land zoned single-family residential, or open a manufacturing facility on land zoned commercial, no variance will help you — the use itself is prohibited. You need to change the zone.
Because rezoning is legislative, courts give it significant deference. The government has broad authority to decide how land should be used across its jurisdiction. The main checks are constitutional limits (the taking problem, equal protection) and the requirement that rezonings be consistent with the comprehensive plan in most states.
What a Variance Does
A variance provides relief from specific dimensional or operational requirements of the zoning code without changing the underlying zone. It's a quasi-judicial act — decided by a board of zoning appeals (BZA) or board of adjustment, applying legal standards to the specific facts of your property.
There are two types. An area variance (also called a dimensional variance) provides relief from physical standards like setbacks, lot coverage, building height, and floor area ratio. A use variance allows a use not otherwise permitted in the zone, though many states have moved away from use variances because they effectively allow case-by-case rezonings without the comprehensive plan review.
A variance is the right path when your use is already permitted in the zone, but the dimensional standards of the code prevent you from implementing the project as designed. If you want to build a house on a residential lot but can't meet the front setback because of the lot's unusual shape, a setback variance addresses the specific constraint without changing anything else about what's allowed on the lot.
The Legal Standards Are Different
Rezoning has no mandatory legal standard — the legislative body has broad discretion, and the standard is essentially "is this a reasonable policy decision?" Variances, by contrast, require meeting specific legal criteria established by state law. The traditional variance test requires showing:
- Hardship unique to the property: The physical characteristics of this specific lot — shape, size, topography, existing structures — prevent compliance. Financial hardship alone doesn't qualify.
- Not self-created: The hardship wasn't caused by the current owner's actions. If you subdivided a lot and made it nonconforming yourself, you can't then claim hardship from the nonconformity.
- Not contrary to the public interest: Granting the variance won't harm the neighborhood or undermine the purposes of the zoning code.
- No harm to adjacent properties: The variance won't deprive neighboring owners of rights they're entitled to under the zoning.
The variance standard is strict, and boards of appeal are supposed to apply it consistently. In practice, some boards are more lenient than others, and the quality of the application — the narrative, the site plan, the comparables, the neighbor support — matters a lot.
Cost and Time Differences
Rezoning is typically slower and more expensive than a variance. A full rezoning process involves:
- Planning staff review (weeks to months depending on the municipality)
- Planning commission hearing and recommendation
- City council or county board hearing and vote
- Possible environmental review (CEQA in California, SEPA in Washington, NEPA for federal nexus)
- Potential appeals period after approval
In a complex municipality, a contested rezoning can take one to three years. In smaller towns, it can be done in three to six months. Application fees range from a few hundred dollars in small towns to tens of thousands in major cities.
A variance goes only to the board of appeals, skipping the planning commission and elected body. Many boards meet monthly, and simple variance applications can be resolved in one or two hearing cycles — often two to four months from application to decision. Fees are typically lower, and the process is less politically exposed.
Which Is More Predictable
Variances are more predictable — not necessarily easier to get, but more rule-bound. A strong variance application that clearly satisfies the legal criteria and has no significant opposition usually gets approved. A weak application that doesn't establish unique hardship usually gets denied. The criteria are clear; the question is whether your facts fit them.
Rezoning is fundamentally political. A project that checks every planning box can still get denied by a city council facing neighborhood opposition. Conversely, a project that barely fits the comprehensive plan can get approved by a council that wants economic development. Political risk is higher, and the outcome is harder to predict from the legal record alone.
How to Decide Which Path to Pursue
Start by identifying the specific problem. Is the use prohibited in the current zone? You need a rezoning (or a conditional use permit if the use is conditionally permitted). Is the use allowed but a dimensional standard prevents the project? You need a variance.
If you're facing a use that's conditionally permitted — allowed with specific conditions through a conditional use permit(CUP) or special use permit — that's a third path that's often faster and less politically exposed than rezoning. Review the use table in the ordinance carefully before deciding which mechanism applies.
Sometimes you need both: a rezoning to permit the use and a variance to address a dimensional constraint. That's the most complex scenario — sequential processes with separate decision-makers, and failure at either step kills the project. Experienced land use attorneys and entitlement consultants earn their fees in these situations.
