What to plan for in Severn and Hanover
Two counties in Hanover
The 21076 ZIP spans Anne Arundel and Howard Counties. Check which county your home is in before you plan, since permits, inspections and zoning rules come from that county.
BWI noise zone
Homes close to BWI may sit inside the airport's noise contour. The state's sound insulation program for eligible older homes has been paused since January 2026 while the noise map is updated, so plan window and insulation upgrades on your own timeline.
Townhomes and HOAs
Much of the newer housing here is in HOA or condo communities. Exterior changes such as decks, doors, windows and siding usually need association approval in addition to the county permit, so get both lined up before you schedule work.
