What Is Condemnation
Condemnation is the legal process by which a government entity acquires private property for public use, typically through the power of eminent domain. The government must pay the property owner just compensation, which is defined as fair market value at the time of the taking.
For property owners, condemnation creates immediate assessment and valuation challenges. When a portion of your property is condemned, your assessed value often remains artificially high because it reflects the pre-condemnation value. This directly inflates your property tax bill and is a legitimate ground for appeal at your board of review hearing.
Condemnation and Property Tax Assessment
Assessors typically lag 12 to 18 months behind condemnation proceedings. Your property was valued and assessed at full market value, but if a government agency has taken or is taking a portion of your land for a highway, utility right-of-way, or public project, your remaining land's utility and income potential have changed. The assessment must reflect this diminished use.
Use comparable sales of similarly diminished properties to build your appeal. For example, if your commercial lot lost 2,000 square feet to road widening, find recent sales of comparable properties with similar acreage reductions. Document the percentage loss in value, not just the square footage lost. A corner parcel losing 15% of its area may lose 25% to 35% of its market value due to reduced visibility or access.
Key Steps in Condemnation Appeals
- Obtain the official condemnation notice or declaration from the acquiring agency. This document establishes the effective date and the legal description of the property taken.
- Request a recent appraisal of the remaining property using the income approach or sales comparison approach. Appraisers will value the property as if the taking had already occurred.
- Calculate the assessment ratio for your property and compare it to surrounding unaffected properties. If your assessment is 40% of the pre-condemnation value but ratios in your area average 32%, you have a clear argument for reduction.
- Gather comparable sales from properties that experienced similar partial takings within the past 18 months. Real estate databases and county records show actual transaction prices post-condemnation.
- Prepare documentation showing loss of income or use. Retail properties may show reduced sales; agricultural land may show reduced productivity or access.
- File your appeal before the statutory deadline, typically 30 to 45 days after the assessment notice date. Include your appraisal, comparable sales, and the condemnation document.
- Present evidence at the board of review hearing. Focus on what the remaining property is worth now, not what it was worth before.
Common Questions
- If the government condemns part of my property, does the assessment automatically drop? No. You must file an appeal with documentation showing the new market value of the remaining property. Assessments do not adjust automatically for partial takings.
- Can I use the just compensation the government offered as proof of market value? Possibly, but only if the compensation was determined through arm's length negotiation or court award. If it was a quick take or preliminary offer, it may understate fair market value. Use it as supporting evidence, not your primary proof.
- What if the condemnation is pending but not yet complete? You can still appeal if the taking is legally certain and documented. Assessors must value property as of the assessment date. If a taking is imminent and publicly announced, the property's value reflects that certainty, and your assessment should reflect a reduced value.

Eminent Domain is the government's legal authority underlying condemnation. Just Compensation is what you must receive when property is condemned, and disputes over that amount often connect to assessment appeals because it establishes baseline fair market value.
