Aging-in-Place Remodeling in Baltimore County, MD: Costs, Licenses

Baltimore County had 168,779 residents 65 and over on July 1, 2025, 19.9% of the county, the second-largest count in Maryland and up 11.8% since 2020 (Census Bureau Vintage 2025 population estimates). It also has the oldest housing of Maryland's big suburban counties: the median home was built in 1973 and 59.5% of units predate 1980, from Catonsville to Dundalk to Towson, 47.2% of them detached houses and 23.7% rowhouses and townhouses. Contractors need a Maryland Home Improvement Commission (MHIC) license and, for plumbing, a Baltimore County plumbing license. The work that comes up most is a stair lift, a bathroom that still has its 1970s tub, and a safer front step.

The homes here

Built before 1980. In the suburbs built in the 1960s and 1970s that means two-story houses and split-levels over a basement, with the bedrooms and the only full bath upstairs. A stair lift on the main staircase is the first project most families consider, and a main-floor bedroom and bath is the bigger answer when the stairs are not the only problem.

Rowhouse blocks. Nearly a quarter of county homes are attached (23.7%), and rowhouse blocks along the city line share Baltimore City's pattern: steep, narrow stairs and often no bath on the first floor. A stair lift fits most of them; when it does not, a first-floor powder room or back room becomes the full bath.

The 1970s bathroom. A tub with a high wall, a door too narrow for a walker, and a floor that was never meant to stay wet. A bathroom safety remodel means a curbless shower where the tub was, grab bars into the studs, a comfort-height toilet and a non-slip floor.

Winter. Maryland averages 20.6 inches of snow a season and winter temperatures of 34.1 F (Maryland State Archives), and a 1970s stoop has no cover and often one railing or none. A covered landing, rails on both sides and a ramp with a non-slip surface are the entry work here.

Licensing and permits in Baltimore County

Every home improvement contractor in Maryland needs an MHIC license, with no minimum job size and the license number on the written contract; the state page on aging-in-place remodeling in Maryland covers the one-third deposit cap, the Guaranty Fund and the $500,000 insurance rule. Baltimore County is one of only two places in Maryland (the other is the WSSC area) that issue their own plumbing licenses and code, so the plumber on your bathroom job holds a county license, not a State Board of Plumbing license. Electricians have held a state license since July 1, 2021, and the county issues permits and inspects under the Maryland Building Performance Standards, which adopt the 2021 International Residential Code.

Who pays

Most Baltimore County families pay directly, from savings, home equity or siblings splitting the cost; see paying out of pocket. The Baltimore County Department of Aging is the county's Area Agency on Aging, reached through Baltimore County Maryland Access Point at 410-887-2594. It runs BCAUSE (Baltimore County Age-Friendly Upgrades for Seniors) with Civic Works, Rebuilding Together Baltimore, CHAI and Dundalk Renaissance: homeowners 65 and over at or below 50% of the area median income can get up to $4,500 of repairs or safety modifications, and the program had served 480 households as of August 2026. The state's Accessible Homes for Seniors program (0% deferred loans, and grants up to $15,000 for lower-income owners who cannot carry a loan) also applies here. For Medicaid, ask the Maryland Department of Health whether home modifications are covered in your situation and whether there is a waitlist. Medicare and Medicare Advantage and long-term care insurance each cover narrow cases.

Common projects in Baltimore County

• Stair lift: a straight rail for a straight run, a curved rail for a turn. $3,000 to $20,000 nationally, averages $7,000 to $8,000.
• Bathroom safety remodel: curbless shower, grab bars, comfort-height toilet, non-slip floor. $6,600 to $28,000 for a full remodel; a curbless conversion alone is $2,500 to $9,000.
• Walk-in tub: $3,000 to $15,000 installed, average near $5,000; a curbless shower usually serves a wheelchair better.
