Doorway widening before wall close-up checklist

A concealed-work checklist for widening an interior or exterior doorway: confirming required finished clear opening and approach, determining bearing and braced-wall functions, obtaining structural design where needed, protecting wiring, plumbing and HVAC, installing approved headers, king and jack studs or engineered framing, maintaining fire, smoke, acoustic and weather assemblies, planning threshold and floor transitions, backing hardware, checking pocket or swing conflicts and photographing the completed framing before insulation, trim or drywall hides the work.

Required finished clear opening, approach and door operation are marked from finished surfaces

Critical item

The user needs usable opening after frame, stops, hardware and finishes.

Bearing, braced-wall and load-path functions are identified and designed before cutting

Critical item

Structural framing should not be improvised.

Wiring, plumbing, ducts and controls are relocated by qualified trades without hidden conflicts

Critical item

Services should remain protected and accessible.

Fire, smoke, acoustic, exterior weather and insulation layers are restored

Critical item

Opening changes should preserve required separation and enclosure continuity.

Hinges, closers, automatic operators, rails and future hardware have solid support and power where planned

Critical item

Heavy or assisted doors require coordinated backing and services.

Finished opening forecast, frame plumb, threshold build-up and concealed framing photos are accepted

Critical item

Close-up should wait until geometry and structure are verified.

Use after demolition and framing but before wall close-up. Nominal door size is not the same as finished clear opening. Do not use a checklist to prescribe medical care, transfer technique or mobility equipment. Do not remove structural framing, build ramps or guards, alter stairs, bathrooms, electrical work or gas systems without required design and permits. ADA Standards do not automatically govern every private single-family home; applicable law, program requirements and the approved project control.

    Home accessibility needs and route plan checklist

    A pre-design checklist for documenting the actual users, mobility devices, assistance needs, likely future changes and emergency considerations; tracing a continuous route from parking or drop-off through an entrance to essential living spaces; measuring doors, halls, turns, thresholds and floor changes; identifying bathroom, bedroom, kitchen and laundry priorities; separating immediate safety work from major reconstruction; and approving a realistic phased accessibility plan before products or contractors are selected.

    Whole-home aging-in-place final walkthrough checklist

    A whole-home final walkthrough for verifying the planned step-free route, entrances, doors, bathroom and kitchen functions, bedroom and laundry access, stairs, handrails, lighting, floor transitions, controls, storage and emergency egress as one connected system; confirming required permits and specialist corrections, checking user-specific mock-ups against finished conditions, testing hardware and fixtures safely, documenting maintenance and future adaptation points and closing the project only after unresolved barriers and temporary measures are assigned.

    Step-free entrance before construction checklist

    A pre-construction checklist for selecting the most reliable step-free entrance, verifying parking or drop-off connection, exterior route width and cross-slope goals, drainage and snow or weather exposure, landing and door maneuvering space, threshold and water-management details, lighting, handrail or guard needs, structural support, utility and property constraints, door operation and security, and an alternate emergency route before excavation, concrete, decking or door replacement fixes the geometry.

    Residential ramp footing, landing and handrail checklist

    A stage checklist for a residential access ramp covering excavation and footing approval, post and beam support, ramp width and running or cross-slope goals, level landings and direction changes, edge protection, handrails and guards where required, slip-resistant decking, fasteners and corrosion protection, drainage and snow clearance, transitions to grade and doorway, lighting, structural movement, documentation and functional testing before final acceptance and routine use.
