Do I need a permit for basement finishing in College Park?

Permit likely required

Most likely yes. Basement finishing usually requires a permit in Maryland. Confirm the specifics with College Park.

When a building permit is issued for an alteration to a one- or two-family home or for an additional residential unit, State law requires smoke alarm placement to be upgraded to at least one alarm on each level, including basements (Public Safety 9-104). Local jurisdictions may not weaken the energy code in the Standards (COMAR 09.12.51.05), so finished basement walls must be insulated to the 2021 IECC levels as adopted in Maryland. State law requires every electrical installation to be certified by a governmental inspection unit or a State-certified nongovernmental electrical inspector within 15 days of completion (Public Safety 12-605). This basement project adds a bedroom, a bathroom or wet bar, or new electrical circuits, or moves the furnace or water heater. Finishing work of this kind normally needs a building permit and the matching trade permits. A basement bedroom needs an emergency escape and rescue opening, such as an egress window or door, which is one of the most common reasons basement work fails inspection. Plan for framing, electrical and plumbing rough-in inspections before insulation and drywall go up.
