Start by checking with Collin County Central Appraisal District (www.collincad.org). Once on the website click on the Property Records search option which gives you the option to search for real property by account number, address or owner name. Once you have found the property, open the record and look beneath the owner’s name, mailing address and location, and look at the legal description. If the description includes a subdivision name as well as lot and block, it is likely that the property is platted. If the description includes information such as tracts or abstract, it is likely that the property is not platted. To view the plat or abstract map, you can also click Plat Map or Plat Map Image beneath the Maps and Forms section of the property page. Please contact the Development Services Department at 972-924-2616 to verify whether or not your property is platted.
