Before your demolition can begin, you'll need to obtain a permit
from the City of Dallas. This "master permit" covers all construction and demolition work for your property. There are a few instances where a permit is not required for residential applications. For commercial buildings, the only time a permit would not be required is when remodeling or demolishing the interior of a structure. All other demolitions will require the $42 permit + $0.021 per sqft of the structure. Turnaround time for most permits is same-day.
