Land Value vs Improvement Value on Tax Records
Land value vs improvement value: why assessors split a parcel's value between ground and buildings, and why the split matters for taxes and insurance.
Land value vs improvement value is the split most assessors make when they value a parcel. Land value is the estimated worth of the ground itself, as if vacant. Improvement value is the worth of buildings and other structures, such as a house, garage, pool, or barn. The two add up to the total assessed or market value shown on the property record card and tax bill. Understanding the split helps owners check assessments, estimate depreciation for rental property, and think about insurance coverage, which generally protects buildings rather than land.

How assessors set each value
| Component | Common methods |
|---|---|
| Land | Sales of vacant land, land tables by neighborhood, residual from improved sales |
| Improvements | Cost tables minus depreciation, adjusted to market |
Land is often valued per acre, per square foot, or per front foot, with adjustments for size, shape, frontage, topography, and views. Improvements are valued based on size, quality, age, and condition.
Where to find the split
The property record card and online assessment pages usually show land, building, and total values separately. Tax bills may show only totals.
Why the split matters
- Income tax depreciation: For rental or business property, only the building can be depreciated, not land. Some owners use the assessor’s ratio to allocate purchase price.
- Insurance: Homeowners policies cover rebuilding the structure, not the land, so total market value is not the right coverage amount.
- Assessment review: A land value much higher than neighbors’ may signal an error in lot size or classification.
- Land value taxation: A few places tax land at a higher rate than improvements to encourage development.
Changes over time
Buildings usually depreciate as they age, while land values often rise with demand. In many areas, land is a growing share of total value. A property revaluation may change the split noticeably.
Assessed vs market
Both components may be shown at assessed value, a percentage of market, or at full market value depending on the state. See assessed value vs market value.
Teardowns and redevelopment
When land value is a large share of total value, an older house may be worth little compared to the lot. That is a sign that redevelopment or a teardown is likely in the neighborhood.
Example
A record card shows land at $180,000 and improvements at $270,000, for a total of $450,000. An investor buying the property as a rental for $500,000 might use the 40 to 60 split to allocate $200,000 to land and $300,000 to the building for depreciation, subject to tax advice.
Checking for errors
Compare your land value to similar lots on your street. If your lot is the same size but valued much higher, check the recorded acreage and zoning classification on the card.
Bottom line
Assessors split total value into land value, the worth of the ground, and improvement value, the worth of buildings. The split appears on property record cards and matters for depreciation, insurance, and assessment review. Check it against neighbors to spot errors. Find county assessors via the Platbookmapper map.
