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

When A Window Replacement Needs A Permit

The short answer is that many like-for-like window replacements in Baltimore City do require you to think about permitting, especially when the work changes the size, opening, structure, or appearance of the opening.
