About the Chatham Property Market
Chatham is a city located in Chester County, Pennsylvania. Every property inside the Chatham city limits is assessed by Chester County Board of Assessment Appeals, which applies Pennsylvania property tax rules uniformly across the county.
Because Chatham property values are set at the county level, the $410,000 county median home value and 1.63% effective tax rate apply to homes throughout the city. Homeowners who believe their Chatham home is over-assessed have the right to file a appeal directly with Chester County Board of Assessment Appeals before the August 1 deadline.
Pennsylvania allows the assessor to defend or adjust the assessed value during a appeal, so Chatham homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Chatham Property Market Context
Chatham sits within Pennsylvania's broader property tax landscape as a city, and local assessments reflect both state rules and county-level mass appraisal practices.
Pennsylvania market character
Pennsylvania counties use base-year valuations, and some have not reassessed in decades, producing wildly inconsistent assessed-to-market ratios. The state publishes Common Level Ratios (CLRs) that are essential for winning appeals, especially in counties with outdated base years.
How Pennsylvania handles appeals
Pennsylvania homeowners appeal to the county Board of Assessment Appeals, then the Common Pleas Court. Appeals can be filed by school districts in the other direction, so evidence must be solid.
When to file in Chatham
Annual appeal deadlines vary by county but generally fall between August 1 and October 15. Allegheny County's deadline is March 31.

Single-family homes
