Data Sources: Public records often rely on tax assessment data, which may not be updated frequently. These records may not reflect recent renovations, additions, or changes to a property. In contrast, ANSI standard measurements are typically based on current and accurate measurements conducted by professionals using standardized methods.
Variability in Data Collection: Public records may be generated from a variety of sources, including tax records, building permits, and historical data. These sources may use different measurement criteria or may not account for certain areas of a property, leading to discrepancies.
Estimations: In some cases, public records may rely on estimated measurements rather than precise measurements. For example, tax assessors may use exterior dimensions of a property to estimate its interior living area, which can result in inaccuracies.
Exclusions and Inclusions: ANSI standards for measuring living area provide specific guidelines for what should be included and excluded from the measurement. Public records may not adhere to these standards, leading to differences. For example, a basement or attic space that meets ANSI criteria for inclusion in the living area measurement may not be included in public records.
Updates and Changes: ANSI standards are periodically updated to reflect changes in industry practices and technology. Public records systems may not always keep pace with these updates, leading to differences in measurement criteria and accuracy.
Human Error: Public records may be subject to errors in data entry or recording, leading to inaccuracies in reported living area measurements.
Incentives for Underreporting: In some cases, homeowners or property owners may have incentives to underreport the living area to reduce property taxes or for other financial reasons. This can lead to discrepancies between public records and ANSI-standard measurements.
Local Variations: Public records can vary significantly by location and jurisdiction. Different municipalities and counties may have different standards and practices for recording property data.
Due to these and other factors, it's not uncommon for public records to differ from ANSI standard measurements of living area. When buying or selling a property, it is advisable to rely on professionally conducted measurements that adhere to recognized standards like those set by ANSI to ensure accuracy and transparency in real estate transactions. Agents, Buyers and sellers can also consider obtaining an independent appraisal or measurement verification to confirm the living area's size.
