Top Permit Questions for Window and Door Projects in Montgomery County, MD

The First Question: Do You Need A Permit?

A lot of permit confusion starts with a basic assumption, that if the replacement matches the old opening, the paperwork should be minimal.

If you are comparing contractors, ask these questions before the estimate is final:

• Will this be treated as like-for-like or as a permitted alteration?
• Does the work change any opening size, framing, or egress condition?
• Are HOA or historic approvals needed before ordering?
• Who is responsible for permit filings and inspections?
• What product choice best fits the home's exposure, age, and layout?

The safest approach is boring, but effective: verify the permit path first, confirm the community rules second, then order the product third.
