30. The Impact of Zoning Laws on Your Property Taxes

30. The Impact of Zoning Laws on Your Property Taxes gives you a clear, step-by-step way to understand what drives your bill, what to verify on your notice, and what to do if the numbers look off.

Zoning laws — which dictate how land and buildings can be used — can have a major influence on property taxes. Even though zoning is an urban planning tool, it ties directly into how your property is assessed and taxed. Here’s what you need to know: Zoning Classifications Affect Assessment Rates Many jurisdictions classify property by its use (residential, commercial, agricultural, etc.), and each class can be assessed or taxed differently. For example, Tennessee law explicitly states that industrial/commercial properties are assessed at 40% of value, while residential and farm properties are assessed at 25% 29 . This means that if your zoning changes from residential to commercial, your effective tax rate could

7 shoot up simply because of the new class, even if the land area is unchanged. Likewise, vacant land is often taxed based on its “highest and best use” after considering zoning 30 , so land zoned for development might face higher taxes than if it were zoned agricultural.

• Rezoning can raise taxes: If your property is rezoned for a more valuable use (say, from single-

family to multi-family or mixed-use), its assessed value may jump to reflect that potential. This is because assessors often consider the highest and best use of the land. A developer’s plan for an apartment complex on your street may increase the base value of your lot. In practical terms, neighbors might see their assessments increase if the city upzones an area.

• Downzoning can lower taxes: Conversely, if zoning becomes more restrictive (e.g. new historic

preservation rules or environmental protections), your property’s value – and thus taxes – may be lower. For instance, farm zoning or conservation zoning often entitles landowners to special “use- value” assessments (taxed on agricultural use rather than full market price). In California, farmland under certain contracts is taxed on its agricultural value instead of market value 31 , saving owners tens of percent on their tax bill. Special Zoning Programs and Exemptions Some laws tie tax breaks to zoning-like conditions. For example, special zones for affordable housing or economic development sometimes offer tax abatements or lower assessment rates for a period. Likewise, “urban agriculture” zones in California allow landowners to get agricultural tax treatment if they commit to

farming. While not all areas have formal programs, it’s worth checking if your city offers any zoning incentives (e.g. brownfield redevelopment credits, urban renewal districts, etc.) that affect property taxes. What Homeowners Can Do

• Monitor zoning changes: Zoning changes (like annexation or reclassification) usually go through

public hearings. Pay attention to local planning commission agendas. If your property is affected, it could alter your tax situation.

• Challenge zoning errors: If your home is zoned incorrectly in the county’s records, this can lead to

wrong classification and taxes. For instance, if your legal address is still marked as “vacant” or “commercial” on record, file a correction with the assessor.

• Plan for future use: If you’re buying a lot, consider its zoning. Land zoned for single-family will stay

lower-taxed than multi-family or commercial. If you plan to change the use, be ready for a higher tax bill.

• Take advantage of programs: In some states, owners of qualified property (like historic homes or

eco-friendly developments) can get special tax credits. Check with your state’s revenue or natural resources department. In summary, zoning can be a hidden factor in your property taxes. The key is to understand your property’s zoning classification and any changes to it, since that often determines your assessment rate. To learn more about local zoning and tax impacts, consult your assessor’s zoning maps (often online) and contact your city’s planning department. PropTaxHelper’s local guides can also help explain how zoning in your state or county ties into property valuations. By staying informed, you can anticipate tax changes and even use zoning incentives to your advantage. 8
