Plats are recorded and maintained by the Dallas County Clerk's Office. Official and Unofficial copies may be requested from the County. Copies of subdivision plats may also be obtained through the City of Irving Capital Improvements Program (CIP) Department at (972) 721-2768 or email. These copies can be delivered electronically at no charge or hard copies can be made at $3 per sheet.
The city does not have copies of individual property surveys. These typically are found in your mortgage or deed records, or you can hire a registered surveyor to complete a survey of your property.
