Is it different in a Denton historic district?
Yes. A Certificate of Appropriateness comes first.
Details: Exterior repairs, alterations and visible changes in the Oak-Hickory, West Oak Area and Bell Avenue local historic districts need a Certificate of Appropriateness. The Historic Preservation Officer can approve minor maintenance; bigger projects go to the Historic Landmark Commission, and no building permit is issued until the certificate is approved.

My house is in the Oak-Hickory district. Can I replace the windows?
Possibly, but only after the city approves a Certificate of Appropriateness. Start that application before ordering anything, because the building permit can’t be issued until it’s approved.
