Do you need a permit for attic insulation in Annapolis, MD?

Usually no

A permit is usually not required for attic insulation on its own. Annapolis still applies zoning rules such as setbacks, lot coverage and HOA approval, and any structural, electrical or plumbing work added to the job does need a permit.

Annapolis sits in Anne Arundel County, Maryland. Deep frost lines, snow load and a very old housing stock mean permits frequently touch structural, electrical and energy-code upgrades at once. Work outside city limits is permitted by the county building department rather than the city.
