The Harris County Appraisal District makes detailed plat maps available at HCAD.org. These maps are updated on January 1 each year, except for properties undergoing changes, such as combining with or dividing into other properties. The index map is divided by school districts.
Searching for a plat requires the user to either know the property's facet number or to locate the property on three progressively more detailed maps. The user can view the final map with Adobe Reader, and it is formatted to print on standard-size paper. Specific property details are not available on plat maps but can be found elsewhere on the HCAD website.
