Short answer. Aging in place modifications focus on fall prevention (bathroom and flooring), access (doorways, hallways, single-floor living), and adaptive controls (lighting, handles, smart home). Plan in stages while the owner is healthy. Reactive modifications after an event cost 2 to 3 times more.
Bathroom (the highest-priority area)
- Curbless walk-in shower with linear drain.
- Slip-resistant tile flooring (DCOF rating 0.42 or higher).
- Grab bars at toilet and shower (mounted into blocking, rated for 250 lb).
- Comfort-height toilet (17 to 19 inches).
- Hand-held shower head on slide bar.
- Built-in shower bench.
- Wall-hung vanity with knee clearance.
- Lever handle faucets.
- Thermostatic shower valve (prevents scalding).
- Bright LED lighting with night-light circuit.
- Wider doorway (32 to 36 inches clear).
Kitchen
- Cabinet pulls (not knobs) for easier grip.
- Pull-out shelves in lower cabinets.
- Drawer microwave at counter height.
- Side-opening wall oven.
- Induction cooktop with auto shut-off.
- Single-lever faucet with pull-down sprayer.
- Under-cabinet lighting (3000K to 4000K).
- Comfortable counter heights (mix of 34 and 36 inch).
- Knee clearance at primary sink and prep area.
- Slip-resistant flooring.
- Open layout with wider walkways (42 to 48 inches).
Entry and exterior
- No-step entry at primary entry (zero threshold or ramp).
- Covered entry with bench seating.
- Lever door handles.
- Smart deadbolt with keypad.
- Wide doorways (36 inch clear).
- Slip-resistant exterior paving.

- Handrail along entry steps where steps remain.
- Wider driveway and garage area for assistive devices.
Hallways and circulation
- 42 to 48 inch wide primary hallways.
- 36 inch interior doorways.
- Reduced thresholds at room transitions.
- Slip-resistant flooring throughout.
- Removal of throw rugs (tripping hazard).
- Even sight lines from primary living areas to bedrooms.
Lighting and controls
- 3-way switches at every room entry.
- Rocker style switches (not toggle).
- Motion-sensor lighting in bathrooms and hallways.
- Bright general lighting (warm white 3000K).
- Night-light circuit for bathrooms and hallways.
- Smart home integration (voice control for lights, locks, thermostat).
- Visual smoke alarms for hearing-impaired residents.
Bedroom and master suite
- Bedroom on the main floor.
- King bed clearance on three sides.
- Reachable closet hanging rods (52 to 60 inch height).
- Accessible closet storage with pull-out drawers.
- Bedside reading lights with reachable switches.
- Direct access to bathroom (no hallway between).
Major structural projects
- Single-floor master suite addition (when current master is upstairs).
- Stair lift or residential elevator.
- Garage to single-floor living conversion.

Phased approach
- Phase 1 (immediate, under $5,000): grab bars, lever handles, brighter lighting, slip-resistant rugs removed.
- Phase 2 (within 5 years, $25,000 to $80,000): bathroom remodel, curbless shower, kitchen tweaks, entry ramp.
- Phase 3 (long-range planning, $100,000 plus): single-floor master suite, elevator, or full home aging-in-place package.
