Replacing windows in a historic district is rarely just a matter of matching sizes and ordering glass.

In Pinellas County, the pressure is twofold: you want windows that can handle wind, rain, and salt air, but you also have to respect the rules that protect older facades and neighborhood character.

How Permits And Design Review Usually Work
