What are Special Assessments? 

Special assessments are charges lived on certain properties to fund a specific local improvement, such as new sidewalks, road resurfacing, or sewer upgrades. Unlike general property taxes, which cover city-wide services, special assessments apply only to properties that directly benefit from a particular project.

Key Takeaways

• Special assessments fund specific improvements, not general services. Unlike property taxes, which fund city-wide needs, special assessments charge only the properties that local authorities determine will benefit.
• They are based on assumed benefit rather than property value. Since special assessments are calculated based on projected benefits rather than property valuation, disputes often arise over whether the charge is justified.
• Disputing a special assessment requires challenging the benefit calculation, a clerical error, or procedural failures. Homeowners may contest assessments if they do not truly benefit from the improvement, if there was a miscalculation, or if the proper legal procedures were not followed.

How Special Assessments Differ from Property Taxes

Special assessments and property taxes may seem similar, but they operate on different principles and have distinct financial and legal implications for property owners. Property taxes are recurring, levied annually or semi-annually, and based on the assessed value of a property. They serve as a general revenue source for local governments, funding services such as schools, emergency services, and infrastructure maintenance. Because they are tied to property value, property taxes fluctuate based on market conditions and reassessments.

Special assessments, by contrast, are one-time or limited-term charges imposed on specific properties to fund particular improvements, such as road repairs, sewer upgrades, or new sidewalks. Instead of being based on a property’s market value, they are supposed to reflect the direct benefit received from the project. Where property taxes apply broadly to all taxable properties within a jurisdiction, special assessments should only be charged to those directly benefiting from the improvement. Additionally, while property taxes recur indefinitely, special assessments are generally imposed for the duration of the project’s financing or until the cost is repaid.

Disputing a Special Assessment

Property owners can challenge a special assessment, but the process differs from appealing property taxes. Instead of arguing over property value, disputes focus on whether the property actually benefits as much as claimed, whether the charge was calculated correctly, or whether the process was legally followed.

• Lack of Benefit: One of the strongest arguments against a special assessment is that the property does not actually benefit from the improvement. For example, if a homeowner is charged for a new sidewalk but their house sits far back with a private driveway, they may argue that their use of the sidewalk is minimal compared to others. Similarly, a property owner on a private road may challenge an assessment for city street repairs, as their property does not connect to the improved area.
• Calculation Errors: Clerical mistakes and incorrect formulas can lead to overcharges. If an assessment is based on property frontage, but an incorrect measurement was used, the owner may dispute the charge. Likewise, if a vacant lot is classified as a developed residential property, it may be assessed at a higher rate than it should be.
• Procedural Issues: Many jurisdictions require a formal approval process before imposing a special assessment, including notice periods and public hearings. If a homeowner did not receive proper notice or was not given a chance to object, they may have grounds to challenge the assessment’s validity. Some states also require that governments conduct benefit studies to justify an assessment, and if this step was skipped, it could give grounds for disputing the charge.
• Available Exemptions: Some jurisdictions offer exemptions or deferral options for seniors, low-income homeowners, or properties with historic designations. Homeowners should check whether they qualify for any relief programs.

Special Assessments in HOAs and Condos

To make matters even more confusing, if your home is part of a homeowner association (HOA) or condo board, you may encounter another type of special assessment. Unlike municipal special assessments (which are governed by tax law) HOA and condo assessments fall under private contracts, specifically the covenants, conditions, and restrictions (CC&Rs) that govern the association. These charges are usually imposed to fund community-wide repairs and upgrades, such as roof replacements, plumbing overhauls, or structural improvements, and are often imposed when reserve funds are insufficient due to unexpected repairs or budget shortfalls.

Homeowners' association (HOA) and condo assessments, unlike municipal special assessments, are governed by private contracts, specifically the covenants, conditions, and restrictions (CC&Rs) that govern the association. These assessments are levied to cover the costs of community-wide repairs and upgrades, such as roof replacements, plumbing overhauls, or structural improvements. They are often imposed when the reserve fund is inadequate due to unforeseen repairs or budget shortfalls.

Disputing an HOA special assessment is different from challenging a government-imposed one because the argument hinges on contractual obligations rather than tax principles. Owners who want to challenge an assessment should focus on whether the board followed its own governing procedures. Other grounds for dispute may include misuse of funds (such as charging for non-essential expenses or improperly diverting money from reserves) or disproportionate charges (such as assessing all units the same amount despite differences in size, usage, or responsibility for shared amenities).
