Representative photoRemodeling and building in Linthicum
Linthicum (including Linthicum Heights) is a long-established North County community next to BWI Marshall Airport, with tree-lined streets of older homes close to the light rail, I-695 and the BWI business district. Many houses here are decades old, which makes kitchens, baths, basements and additions common projects.
Permits in Linthicum
Linthicum is unincorporated, so building permits come from Anne Arundel County's Department of Inspections and Permits through the Land Use Navigator system.

What to plan for in Linthicum
Airport noise
Parts of Linthicum lie under BWI flight paths and inside the airport's noise contours. When you replace windows, doors or insulation anyway, sound-rated products can cut interior noise noticeably. The state's BWI sound insulation program for eligible homes is paused as of early 2026 while the airport's noise map is updated, so ask about eligibility before you buy windows on your own.
Older homes, older systems
In older houses, opening walls often turns up outdated wiring, galvanized plumbing or undersized electrical service, so leave room in the budget. Homes built before 1978 may contain lead paint: contractors who disturb painted surfaces must be certified for lead-safe work.
Mostly outside the Critical Area
Most of Linthicum is inland, so Chesapeake Bay Critical Area rules rarely apply except on lots close to tidal water along the Patapsco River side. Check the county's Critical Area map for your address; outside it, additions and decks usually have a more direct county permit path than in waterfront towns.
