Do I Need a Permit to Replace Windows in Bethesda, MD?

If you are planning a window project in Bethesda, the permit question comes up early, and for good reason. Some replacements are straightforward maintenance, while others cross into code and approval territory. The answer depends on whether you are changing the size of the opening, touching structural framing, working in a historic district, or replacing windows in a building with HOA rules.

When A Window Replacement Triggers Permit Review
