Do I Need a Permit to Replace Windows in Baltimore City?

Yes, in many cases you do need a permit to replace windows in Baltimore City, but the answer depends on what kind of work you are doing.

• creating a new opening
• changing a regulated exterior elevation
• handling commercial or mixed-use property, which is often reviewed more closely
