Montgomery County by the numbers

• 201,065 residents 65 and over, 18.7% of the county, the most of any Maryland county and up 18.4% since 2020 (Census Bureau Vintage 2025 estimates).

The homes here

Colonials and split-levels, 1960s to 1980s. Nearly half the county's housing predates 1980, and the subdivisions of those decades are mostly two-story colonials and split-levels over a basement. Bedrooms and bath upstairs, laundry in the basement, kitchen between: 3 flights a day for someone with a bad hip. The fix is a stair lift on the main stairs or a main-floor bedroom and bath built out of the dining room, den or garage.

The upstairs bathroom. A 1970s hall bath in Bethesda or Rockville is small, with a tub to step over and a door too narrow for a walker. The usual remodel is a curbless shower where the tub was, grab bars anchored into the studs, a comfort-height toilet and non-slip tile, sometimes with a moved wall to reach a 32 to 36 inch clear opening.

Leisure World and other condos. The owner controls the bathroom and interior doors; the association controls the plumbing stacks, the entry door and anything in a shared wall. Most work there is the bathroom, lever handles and lighting. Get the association's alteration rules in writing before the first quote.

Winter. Maryland averages 20.6 inches of snow a season (Maryland State Archives), and a colonial's front stoop is a few uncovered steps. A covered landing, railings on both sides and a non-slip surface on any ramp are the standard answer.

Licensing and permits in Montgomery County

Every home improvement contractor in Maryland needs an MHIC license, with no minimum job size, and the license number must be on your 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. Two things are different in Montgomery County. Plumbing licenses, the plumbing code and plumbing permits come from WSSC, not the state board. And the county's Department of Permitting Services lists interior alterations, decks and electrical work as permit items, while in-kind swaps of fixtures, cabinets and windows need none; ramps and grab bars are not named on that list, so ask the contractor which rule applies to yours.

Who pays

Most Montgomery County families pay directly, from savings, home equity or siblings splitting the cost; see paying out of pocket. Montgomery County Aging and Disability Services is the county's Area Agency on Aging, and Maryland Access Point (1-844-627-5465) will route you to it. The county's Design for Life program offers a property tax credit for accessibility features and visitable or livable upgrades, though the county's own pages disagree on the caps, and its Single-Family Rehabilitation Loan is closed to new applications. 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) applies here, as does Rebuilding Together Montgomery County. For Medicaid, ask the Maryland Department of Health whether home modifications are covered in your situation and whether there is a waitlist. For Medicare Advantage, long-term care insurance and the VA, senior bathroom remodel programs has the honest version of each.

Common projects in Montgomery County

• Bathroom safety remodel: curbless shower, grab bars, comfort-height toilet, non-slip floor. $6,600 to $28,000 for a full remodel nationally; a curbless conversion alone is $2,500 to $9,000.
• Stair lift: a straight rail for a colonial's main staircase, a curved one for a split-level's turn. $3,000 to $20,000, averages $7,000 to $8,000.
• Main-floor bedroom and bath: converting a dining room or den so the upstairs becomes optional. Cost varies by home; the plumbing run to a new bath drives it.
• Grab bars and railings: cheap hardware, and the labor is anchoring it into studs.
