Houston by the numbers

• 660,682 Harris County residents were 65 or older on July 1, 2025, 13.1% of 5,045,026, up 21.5% since 2020 (Census Bureau Vintage 2025 county estimates).
• Montgomery County (The Woodlands, Conroe): 116,585, 14.9%, up 33.8% since 2020, the fastest growth of any large Texas county; Fort Bend County: 138,013, 14.2% (same file).

The homes here

Harris County built out in the 1970s and 1980s, so the typical house is a one-story on a slab, with 2000s two-story subdivisions in The Woodlands, Conroe and Fort Bend County and pier-and-beam bungalows closer to downtown. None has a basement.

The entry. A slab house has 1 or 2 steps at the door, so a short ramp or step-free entry often does it; a pier-and-beam house, or a manufactured home in Montgomery County (11.5% of its housing), needs a longer ramp with a landing. East of Highway 146, Harris County is inside the Texas Windstorm Insurance Association's catastrophe area, so a new exterior door needs a Texas Department of Insurance WPI-8 certificate to keep windstorm coverage.

The bathroom. A 1988 bathroom has a tub-and-shower combination with a curb and a narrow door. A curbless shower on a slab means cutting the slab or building up the floor for drainage, a line item on the bathroom safety remodel quote. "Grab bar installation houston" is in Google autocomplete, and it is the cheapest first step: grab bars anchored into studs.

The stairs. "Stair lift houston tx" is in autocomplete too; the two-story subdivisions in Montgomery and Fort Bend counties are the reason, and a straight-rail stair lift is the usual fix.

Licensing and permits in Harris County

Texas has no statewide general contractor license and no recovery fund; only the trades are licensed, plumbers by the Texas State Board of Plumbing Examiners and electricians and air conditioning contractors by TDLR. Houston's rule, in its own words: a general contractor's license is not required for the structural portion of the work, but mechanical, electrical and plumbing work must be permitted and performed by a licensed person. Electrical contractors register with Houston Public Works Electrical Inspections (832-394-8860); mechanical and plumbing registration has its own steps. Houston requires a permit for remodeling and any mechanical, electrical or plumbing work; painting and flooring are exempt. Get the contract in writing and signed by both spouses before work starts, as Texas homestead law requires. The Texas page has the state rule and how to choose an aging-in-place remodeler has the checklist.

Who pays

Most Houston families pay directly: no pre-approval, your choice of contractor, work can start this week (paying out of pocket covers savings, home equity and splitting the cost among siblings). The Houston Home Repair Program serves owner-occupants at or below 80% of area median income with taxes current and the home outside the floodway, with consideration for people over 62 and people with disabilities; its funding was exhausted when we checked (832-394-6200). Rebuilding Together Houston also does repairs; eligibility. Reach the Area Agency on Aging through the state line at 800-252-9240. Original Medicare pays nothing toward remodeling, but some Medicare Advantage plans carry a bathroom safety allowance, long-term care policies often include a home modification benefit, and veterans should ask about the VA's HISA grant. For Medicaid, ask the Texas Health and Human Services Commission what is covered and whether there is a waitlist.
