Each year, the assessor estimates what your property would likely sell for on the open market **as of January 1st**, and your property’s physical and locational attributes are key inputs in this valuation. ![Specific Characteristics house signage-1](https://www.fair-assessments.com/hs-fs/hubfs/AI-Generated%20Media/Images/Specific%20Characteristics%20house%20signage-1.jpeg?width=500&height=500&name=Specific%20Characteristics%20house%20signage-1.jpeg) ## How Your Property's Specific Characteristics Are Considered ### 1. **Physical Attributes** - **Size:** Includes both the **heated living area** square footage and the **lot size**. Larger homes and lots typically result in higher valuations. - **Age and Condition:** The year built and overall condition (including maintenance, remodeling, or deterioration) impact assessed value. Newer or well-maintained properties often receive higher valuations. - **Construction Quality:** The materials used (e.g., brick, vinyl, stucco), build quality (basic, average, premium), and structural integrity are major considerations. - **Rooms and Features:** Assessed value reflects the number of bedrooms, bathrooms, and special features like: - Garage or carport - Finished or unfinished basement - Fireplaces - Decks or patios - Central HVAC systems - **Improvements:** Renovations, room additions, roof replacements, or any other permitted work can increase your property’s value. --- ### 2. **Location and Neighborhood Factors** - **Neighborhood Desirability:** Location has a direct effect on property value. Consider: - School districts - Crime statistics - Proximity to retail, parks, highways, and public transit - Market trends in your subdivision or ZIP code - **Lot Characteristics:** A lakefront or corner lot, slope/topography, view, or tree cover may positively or negatively affect value. - **Zoning Classification:** Determines permissible land use. Residential, agricultural, or commercial zoning influences marketability and, in turn, value. --- ### 3. **Comparable Sales Data (Comps)** While not a characteristic of your property itself, **sales data of comparable homes** in your area with similar features is **the most influential factor** in determining FMV. The assessor uses a mass appraisal method based on recent, arms-length transactions. --- ## How the Assessor Gathers This Information - **Property Records:** Maintained by the Gwinnett County Tax Assessor and updated using: - Building permits - Past sale history - Prior assessments - **Field Visits:** County appraisers may inspect your property to verify data, measure exterior features, and photograph for records. - **Aerial Imaging & GIS Tools:** Advanced tools such as **GIS mapping**, aerial photography, and parcel overlays help assess land features and updates. - **Owner-Provided Info:** While homeowners aren’t typically required to submit updates, submitting corrections to incorrect data can be helpful, especially when filing an appeal. --- ## Identifying Common Errors in Property Characteristics When you receive your **Annual Notice of Assessment**, compare the listed property details with your knowledge. Look for: - **Incorrect Square Footage** (living area or basement) - **Wrong Bedroom/Bathroom Count** - **Missing Features** (e.g., deck, pool, garage) - **Incorrect Age or Year Built** - **Outdated Condition Rating** (e.g., if home needs repairs or is not updated like similar nearby homes) If errors exist, these can be strong grounds for a **property tax appeal**. --- ## Why This Matters for Appeals If you believe your property is over-assessed, **accurate documentation of errors** in the assessor’s records is crucial. Correcting these can lower your property's assessed value. When appealing, include: - Property record printouts (with errors highlighted) - Photos showing the property’s condition - Repair estimates, if relevant - Sales of similar properties with different characteristics or conditions --- ## Summary The Gwinnett County Tax Assessor uses a detailed set of physical, locational, and market-based characteristics to determine your property's Fair Market Value. Understanding these factors helps you better interpret your assessment — and gives you a stronger foundation for an appeal if necessary. --- ## Resources - [**Gwinnett County Board of Tax Assessors**](https://www.gwinnettassessor.com) Search property records, review assessments, and file an appeal. - [**Gwinnett County GIS Viewer**](https://www.gwinnettcounty.com/departments/informationtechnologyservices/geographicinformationsystems) View aerial imagery and lot characteristics. - [**PT-311A Appeal Form (Georgia DOR)**](https://dor.georgia.gov/pt-311a-appeal-assessment-form) Use this form to appeal your property tax assessment. - [**Georgia Department of Revenue – Property Tax Appeals**](https://dor.georgia.gov/local-government-services/filing-property-tax-georgia) - [**Gwinnett County Tax Commissioner**](https://www.gwinnettcounty.com/web/gwinnett/departments/taxcommissioner) For questions related to billing, payment, and due dates. ![property tax appeals](https://www.fair-assessments.com/hs-fs/hubfs/2019/icons/blog-sidebar-icon-165x60.png?width=165&name=blog-sidebar-icon-165x60.png "property tax appeals") ### Subscribe to our *A Fair Shake* Blog: [![How Tax Assessors Use Sales to Value Property](https://no-cache.hubspot.com/cta/default/163576/e3546063-41de-49e2-8e46-03a715d129ea.png)](https://cta-redirect.hubspot.com/cta/redirect/163576/e3546063-41de-49e2-8e46-03a715d129ea) [![HOW TAX ASSESSORS USE THE COST APPROACH TO VALUE PROPERTY](https://no-cache.hubspot.com/cta/default/163576/5e017dc4-73d8-4438-a603-74dbb79dada5.png)](https://cta-redirect.hubspot.com/cta/redirect/163576/5e017dc4-73d8-4438-a603-74dbb79dada5) [![New call-to-action](https://no-cache.hubspot.com/cta/default/163576/8252852a-491e-4c1f-9f38-1f129a228e30.png)](https://cta-redirect.hubspot.com/cta/redirect/163576/8252852a-491e-4c1f-9f38-1f129a228e30)  [![linkedin](https://www.fair-assessments.com/hs-fs/hubfs/linkedin.png?width=30&name=linkedin.png)](https://www.linkedin.com/company/fair-assessments-llc/)[![facebook](https://www.fair-assessments.com/hs-fs/hubfs/facebook.png?width=30&name=facebook.png)](https://www.facebook.com/FairAssessments/)  ** Phone: (404) 618-0355** © 2026 Fair Assessments, LLC.
