What to Ask a Contractor Before Starting Accessibility Work in Your Home

Ask about their experience with accessibility work, not just general contracting

A contractor who builds decks or renovates kitchens may not understand accessibility the way someone who has done ramps, grab bars, or bathroom modifications does. The difference matters because accessibility work has specific building codes, safety standards, and installation methods that differ from standard construction.

Ask directly: "How many accessibility projects have you completed in the past three years?" Listen for specific examples — ramps for wheelchair users, walk-in showers, widened doorways, accessible kitchens. Ask whether they've worked with occupational therapists or physical therapists, since those professionals often recommend modifications and know which contractors understand their recommendations.

Request the names and phone numbers of at least three previous clients who had similar work done. Call them and ask whether the contractor understood what they needed, whether the work actually solved the problem, and whether it held up over time.

Key Takeaways

• Ask for specific examples of accessibility projects completed in the past three years, not general construction experience.
• Request references from clients who had the same type of work done — ramp installation, bathroom modification, or doorway widening — and call them to ask whether the work solved their actual problem.
• Confirm the contractor knows the building codes that apply to your city or county, since accessibility standards vary by location and change over time.
• Get a written estimate that breaks down labor, materials, and timeline separately, and ask what happens to the cost if the work takes longer than expected.
• Clarify who is responsible if the work does not meet code or does not work the way you need it to — ask this before signing anything.

Confirm they know the building codes for your location

Accessibility work is governed by building codes that vary by state and sometimes by city. The most common standard is the Americans with Disabilities Act (ADA), but local codes may be stricter or have different requirements. A contractor who did accessible work in another state may not know your local rules.

Ask: "What building codes apply to this project in our city?" They should be able to name them — usually the ADA Standards for Accessible Design, your state's building code, and possibly your city's specific requirements. If they seem uncertain or say "I'll check with the inspector," that is a warning sign. A contractor experienced with accessibility work should know this before you hire them.

Ask whether they pull permits for accessibility work. Some modifications do not require permits, but major ones — like ramps, structural changes, or electrical work — usually do. A contractor who skips permitting to save time is creating a liability for you and may leave work that does not meet code.

Get a detailed written estimate that separates labor, materials, and timeline

A vague estimate ("$5,000 for a ramp") tells you nothing about what you are paying for or what happens if the work takes longer. A detailed estimate breaks down the cost of materials, the cost of labor (usually by the hour or by the day), and the expected timeline.

Ask the contractor to write down: the specific materials they will use (the brand and model of grab bars, the type of ramp surface, the door hardware), the number of hours or days they expect the work to take, and the start and end dates. Ask what happens to the cost if the work takes longer — do you pay extra, or is there a cap? Ask what happens if materials cost more than estimated.

Request a payment schedule in writing. Many contractors ask for a deposit upfront, payment partway through, and a final payment when the work is done. Confirm this in writing before you sign. Never pay the full amount before the work starts.

Ask how they will make sure the work actually solves your problem

Accessibility work is only successful if it actually works for the person using it. A grab bar installed in the wrong place, at the wrong height, or at the wrong angle can be useless or even dangerous. A ramp that is too steep or has the wrong surface can be impossible to use.

Ask the contractor: "How will we know if this is working the way you need it?" If you are having work done because you use a wheelchair, a walker, or a cane, ask whether the contractor will watch you use the finished work and adjust it if needed. Ask whether they will come back after a week or two to check that everything is holding up and working as expected.

If an occupational therapist or physical therapist recommended the work, ask whether the contractor is willing to speak with that professional before starting. Many therapists can clarify exactly what height, angle, or placement will work best for your specific situation.

Clarify who fixes it if the work does not meet code or does not work

Before you sign a contract, ask: "What happens if the work does not meet building code?" and "What happens if the work does not work the way I need it to?" Get the answer in writing as part of your contract.

A reputable contractor should offer a warranty — usually one year — that covers defects in materials or workmanship. This means if a grab bar pulls loose, if a ramp surface cracks, or if a door does not close properly, the contractor will fix it at no extra cost during that year. Ask what the warranty covers and for how long.

Ask whether the contractor carries liability insurance. If something goes wrong — if someone is injured because of faulty work, or if the work damages your home — insurance protects both you and the contractor. Ask to see proof of insurance before work starts.

Ask about the timeline and what happens if work is delayed

Accessibility work sometimes uncovers problems — rotted wood under a bathroom, uneven flooring, plumbing or electrical issues — that were not visible before work started. Ask the contractor: "What usually goes wrong during projects like this, and how long does it take to fix?"

Get a realistic timeline in writing. Ask whether the contractor works on other projects at the same time, or whether they will focus on your work until it is finished. Ask what happens if they get delayed — do they have a backup crew, or will your project wait? Ask whether there are any times of year when they are too busy to take on new work.

Discuss what you need to do to prepare. If they are installing a ramp, do you need to move plants or clear the area? If they are modifying a bathroom, do you need to move your belongings? Ask what the work will be like day-to-day — will there be noise, dust, or disruption to water or electricity?

Ask whether they work with other professionals you might need

Some accessibility projects require more than one contractor. A bathroom modification might need a plumber, an electrician, and a general contractor. A ramp might need a structural engineer to assess the ground. Ask whether your contractor coordinates with other trades or whether you have to hire them separately.

Ask: "Have you worked with an occupational therapist or physical therapist before?" If you are working with one of these professionals, the contractor should be comfortable taking direction from them. Ask whether they have worked with inspectors from your city's building department and whether they know what the inspector will be looking for.

If your work involves multiple contractors, ask who is responsible if something goes wrong at the connection between their work and someone else's. For example, if a plumber installs a new sink and the general contractor installs grab bars around it, who is responsible if the grab bars are not positioned correctly for the new sink?

Frequently Asked Questions

Do I need a contractor for accessibility work, or can I do some of it myself?

Simple projects like installing grab bars or a shower seat can often be done yourself if you are comfortable with basic tools. Structural work — ramps, doorway widening, major bathroom renovation — usually requires a licensed contractor and a building permit. Ask your city's building department what requires a permit in your area before you start.

What should I do if the contractor's estimate seems too high?

Get estimates from at least two other contractors so you can compare. Ask each one to explain what is included in their price. Sometimes a higher estimate includes better materials, a longer warranty, or more experience with accessibility work. Sometimes it is just higher. Do not choose based on price alone — a cheap contractor who does not understand accessibility work will cost you more in the long run.

Can I use a contractor who has never done accessibility work before?

Yes, but only if they are willing to learn. Ask whether they will consult with an occupational therapist, review the building codes with you, and watch you use the finished work to make sure it functions correctly. A contractor who is honest about their inexperience and willing to do the work carefully is better than one who claims expertise they do not have.

What if I disagree with the contractor about how the work should be done?

Put your concerns in writing and ask the contractor to respond in writing. If you are working with an occupational therapist or physical therapist, ask them to weigh in. If you cannot agree, you have the right to stop work and hire someone else, but clarify in your contract what you owe the first contractor for work already completed.

How do I know if the finished work meets building code?

The building inspector will check this when they inspect the finished work — most accessibility projects require a final inspection before you can use them. Ask your contractor when the inspection will happen and whether you can be present. If the inspector finds problems, the contractor should fix them at no extra cost.
