Dallas FAQ
How do I know if my lot is in a Conservation District?
Search the Dallas GIS zoning viewer with your address. CDs and NSOs appear as overlay layers over base zoning. Each district has unique standards in Chapter 51A appendices, so review the specific ordinance before designing additions or new builds.
Can I add a second story without overlay review?
If your lot lacks an overlay, second-story additions follow standard side-yard, height, and lot-coverage rules. Inside a CD or NSO, second-story additions require compatibility review and may need Plan Commission approval, especially for height-plane intrusions.
