What Is Frontage
Frontage is the linear distance in feet that your property boundary runs along a public road, street, or waterway. Assessors measure this distance at the property line where it meets the public right-of-way. On a rectangular lot, this is straightforward. On irregular parcels, assessors measure the actual boundary length along the street, not a theoretical straight line.
Why Frontage Matters in Assessments
Frontage is one of the primary variables in land value calculations, especially for commercial and retail properties. A corner lot with 150 feet of frontage on a main road generates more traffic visibility and foot traffic than a similar lot with 50 feet of frontage on a side street. Assessors use frontage as a direct multiplier in unit-front-foot valuation methods, where they multiply your frontage by a per-foot value derived from comparable sales.
For example, if comparable retail properties in your area sell at $500 per front foot, a property with 100 feet of frontage on Main Street receives a land value of $50,000 based on frontage alone, before any depth or shape adjustments. An incorrect frontage measurement or inflated per-foot rate can inflate your assessment by 10 to 30 percent.
Frontage in the Assessment Process
Assessors source frontage measurements from deeds, property surveys, and county records. During a board of review hearing, you can challenge the frontage measurement if your survey shows a different figure than what the assessor used. Bring a certified survey to the hearing as evidence. If the assessor measured 125 feet but your survey shows 110 feet, that 15-foot discrepancy could reduce your land value by thousands of dollars.
You should also verify that the per-foot rate the assessor applied matches actual comparable sales in your market. Request the assessor's comparable sales list and check whether those properties truly are comparable in location, visibility, and road frontage. A property on a back access road should not use the same per-foot value as a corner lot on a major thoroughfare.
Common Frontage Mistakes in Appeals
- Using old survey data: If your property was subdivided or had boundary adjustments within the last 10 years, the assessor may have outdated frontage information. Get a current survey.
- Ignoring corner lot premiums: Assessors sometimes apply excessive premiums for corner properties. Challenge this by comparing actual sales of corner lots versus interior lots in your area.
- Accepting the per-foot rate without verification: The assessor's per-foot value should come from legitimate comparable sales within the last 12 to 18 months. Properties sold more than two years ago should carry less weight.
- Not accounting for access limitations: If your lot has restricted access or shared driveway rights, the practical frontage value may be lower than face value suggests.
How to Use Frontage in Your Appeal
When you file a board of review appeal, frontage becomes your first line of defense on the land value side. Request the assessor's property record card and ask specifically which frontage measurement was used and from which source document. If the measurement differs from your deed or survey by more than 2 to 3 feet, request a correction before the hearing. Small errors compound when multiplied by the per-foot rate.
Prepare a comparable sales analysis showing actual sales of properties with similar frontage on similar roads in your area. If the assessor valued your 80-foot frontage commercial lot at $600 per front foot but comparable sales show $425 per front foot for similar properties, you have quantifiable evidence to present at the hearing. Bring a three-to-five property comparison showing sale prices, frontage, and sale dates.
Frontage and Exemptions
Frontage measurement is straightforward and does not interact directly with most property tax exemptions. However, if you own a corner lot used partly for residential purposes and partly for agricultural use, the exemption applies only to the portion actually used for that purpose, not based on frontage. Clarify how the exemption boundary aligns with the property line.
Common Questions
Does my waterfront property frontage get valued differently than street frontage?
Yes. Waterfront property (lake, river, or ocean) typically receives higher per-foot values than street frontage because water access adds premium value. Assessors use separate comparable sales data for waterfront properties. If the assessor valued your waterfront lot using standard street-frontage comparables, challenge this at the board of review hearing with actual waterfront sales data.
What if my property is accessed by a private road instead of a public road?
Private road frontage is worth less than public road frontage because access is conditional on easement rights and you cannot control maintenance or improvements. The per-foot rate should be significantly lower. If the assessor applied public road rates to a private road property, request an adjustment based on comparables that actually have private access.
Can I reduce my assessment by reducing my lot's frontage?
No. Frontage is a physical characteristic of your property; you cannot change it without a boundary line adjustment approved by the local surveyor and recorded with the county. However, you can dispute the frontage measurement or the per-foot rate applied to it. That is a legitimate appeal strategy.
