Aging-in-Place Remodeling in Northbrook, IL: Split-Levels, Baths

Northbrook is 26.6% residents 65 and over, with a median home value of $652,300 (Census American Community Survey 2024 five-year estimates), a North Shore village in suburban Cook County, which had 896,689 residents 65 and over on July 1, 2025, 17.3% of the county (Census Bureau Vintage 2025 estimates). The median home was built in 1976, and the stock runs to split-levels and ranches over basements. Illinois has no statewide general contractor license and Chicago's license stops at the city line, so the village registration and the written contract are the checks. The projects that come up most are the bathroom rebuilt curbless, a stair lift on the half-flight and railings on the stoop.

The homes here

A 1976 house on the North Shore. The 1976 median lands in the split-level and raised-ranch years: a half-flight up from the front door to the living room, another to the bedrooms, and the family room and laundry a half-flight down. The lakefront villages are older, Wilmette's median home dating to 1957 (Census American Community Survey 2024 five-year estimates), with two full stories over a basement.

The bathroom. A 1976 hall bath has a tub-shower behind a curtain and a narrow door. The bathroom safety remodel that fits is a curbless shower with a linear drain and a built-in bench, grab bars in the same finish as the faucets, a comfort-height toilet and porcelain with a non-slip rating, with the doorway widened to a 32 to 36 inch clear opening while the wall is open.

The half-flights. A split-level's stairs are short and straight, the cheap case for a stair lift: $3,000 to $20,000 installed nationally, with a straight rail at the low end. A platform lift or a ramp at the entry removes the first half-flight. In a two-story, a main-floor bedroom and bath is the longer answer.

Winter and old paint. Chicago O'Hare averages 38.4 inches of snow a year (National Weather Service, 1991 to 2020), so the stoop gets railings and a covered landing. Any house built before 1978 falls under the EPA's lead rule: paid work disturbing more than 6 square feet of painted surface in a room needs a lead-safe certified firm, which covers most of Northbrook.

Licensing and permits in Cook County

Illinois has no statewide general contractor license. Chicago's Department of Buildings licenses general contractors in five classes by project value, but only inside the city; in Northbrook the village handles contractor registration and permits. The state licenses roofers (IDFPR) and plumbers (IDPH, license number on every ad). The Illinois Home Repair and Remodeling Act applies to every job over $1,000: a written contract with the total cost and the business address, the "Home Repair: Know Your Consumer Rights" pamphlet with a signed acknowledgment, and liability insurance of at least $100,000 per person and $300,000 per occurrence. Ask for the certificate of insurance and check the Attorney General's complaint history. The Illinois page has the full state rule.

Who pays

Most Northbrook families pay directly, from savings, a home equity line or siblings splitting the cost: no pre-approval, your choice of contractor. Paying out of pocket covers the tools. AgeOptions, the Area Agency on Aging for suburban Cook County, is at 708-383-0258. The income-limited help that reaches Northbrook is Community Partners for Affordable Housing, up to $40,000 as a 0% forgivable loan for accessibility work at or below 80% of the area median income, and the state's Home Repair and Accessibility Program, up to $50,000 per home, with a waitlist likely; Rebuilding Together North Suburban Chicago in Glenview does free safety repairs for low-income older homeowners. Modifications made for medical reasons can count as a deductible medical expense (tax deductions), and a long-term care policy often includes a capped home modification benefit. Original Medicare pays nothing toward remodeling; for Medicaid, ask the Illinois Department of Healthcare and Family Services what is covered and whether there is a waitlist; veterans should ask the VA about the HISA grant.
