How to Find and Vet a CAPS-Certified Contractor: 10 Questions to Ask Before Hiring

Why a CAPS-Certified Contractor Is Worth the Extra Vetting Step

The numbers are stark: only about 10% of U.S. homes are considered "aging ready" — meaning they lack a step-free entry, a first-floor bedroom and bathroom, or basic accessibility features. Meanwhile, 93% of adults 65 and older live in their own homes and want to stay there. That gap between desire and readiness is where a Certified Aging-in-Place Specialist (CAPS) comes in.

But here is the uncomfortable truth: the CAPS designation alone does not guarantee that a contractor is the right fit for your specific project. A specialist who excels at bathroom remodels may have limited experience with stair lifts. A contractor with an OT background may approach a project differently than one who comes from general construction. The credential proves they have completed the NAHB training curriculum and pledged to a code of ethics — it does not prove they have done your exact job before.

This guide is built for the crisis-driven reader: the adult child who needs to hire someone quickly after a parent's fall or a sudden mobility decline, but who cannot afford to make a costly mistake. We will walk through the three-step vetting process — directory verification, license and insurance checks, and a 10-question interview framework — so you can move fast without cutting corners.

Step 1: Start with the NAHB CAPS Directory

The National Association of Home Builders (NAHB) maintains the official online directory of CAPS-certified professionals. This is the only authoritative source for verifying that someone holds an active credential. If a contractor claims to be CAPS-certified but is not listed here, that is an immediate red flag.

Here is how to use the directory effectively:

• Go to the NAHB CAPS directory page and search by your zip code or city.
• Look for an active listing with current contact information. Some listings may include specialty areas (e.g., bathroom modifications, kitchen accessibility, whole-home design).
• Cross-reference the name and business name against the contractor's website or business card. Scammers have been known to use the names of legitimate CAPS holders.
• Note whether the listing mentions a background in construction, occupational therapy, design, or another field. This matters because CAPS professionals come from diverse backgrounds — a contractor may approach a project differently than an OT.

The directory is also useful for finding multiple candidates in your area. Most families should interview at least three CAPS professionals before making a decision.

Step 2: Verify License, Insurance, and Workers' Compensation

The NAHB requires all CAPS credential holders who work as contractors to carry specific protections. These are not optional — they are conditions of maintaining the certification. Before you schedule a consultation, ask for copies of the following documents:

• General liability insurance — This covers property damage or injury that occurs during the project. Ask for a certificate of insurance and verify it is current.
• Workers' compensation insurance — If the contractor has employees, this covers medical costs if a worker is injured on your property. If the contractor is a sole proprietor, they may be exempt in some states, but you should still ask.
• Valid business license — Requirements vary by state and municipality. Check with your local licensing board to confirm the contractor's license is active and in good standing.

Do not rely on verbal assurances. A legitimate CAPS contractor will provide these documents without hesitation. If they hesitate, make excuses, or claim they are "covered under a friend's policy," move on.

Step 3: Ask These 10 Questions Before You Sign Anything

Once you have confirmed the contractor is listed in the NAHB directory and has the required insurance and licensing, it is time for the interview. These 10 questions are designed to uncover experience level, project management style, and potential hidden costs. Use them as a checklist during your phone or in-person meeting.

Take notes during the interview. Compare answers across candidates. The goal is not to find a contractor who says "yes" to everything — it is to find one whose experience, communication style, and project approach align with your family's needs and budget.

Red Flags: When to Walk Away

Some warning signs are non-negotiable. If a contractor exhibits any of the following behaviors, do not proceed — even if they are listed in the NAHB directory.

• Demands more than 30% of the total cost as an upfront payment. Industry standard is a small deposit (10–20%) with the balance due upon completion or at agreed milestones.
• Provides only a vague, one-line estimate. A professional CAPS should give you a written, itemized estimate that breaks down materials, labor, permits, and any subcontractor fees.
• Cannot or will not provide proof of insurance or a valid business license. This is a requirement of the NAHB credential — there is no excuse for not having these documents ready.
• Is not listed in the NAHB online directory. If they claim to be CAPS-certified but are not in the directory, they may have let their credential lapse or may be misrepresenting their qualifications.
• Refuses to share references or provides only references from non-senior clients. For aging-in-place work, you need to hear from families who have been through the same process.
• Cannot explain how their modifications will address your parent's specific mobility needs. A good CAPS should be able to connect each recommendation to a functional limitation — for example, explaining why a grab bar at a specific height reduces fall risk during transfers.

Falls are the leading cause of injury among older adults, and home modifications are one of the most effective ways to prevent them. Hiring the wrong contractor can delay critical safety improvements or, worse, create new hazards. If something feels off, trust your instinct and keep looking.

What a CAPS Home Evaluation Should Include

Before any work begins, a CAPS-certified professional should conduct a thorough home evaluation. This is not a quick walkthrough — it is a systematic assessment of the home's current accessibility and the senior's functional needs. A proper evaluation typically costs between $250 and $500 and results in a written report with visuals.

Here is what a quality evaluation should include:

• A room-by-room assessment of hazards and barriers — including doorway widths, threshold heights, bathroom layout, stair conditions, and lighting adequacy.
• Specific, prioritized recommendations tied to the senior's mobility limitations. For example: "Install a 36-inch grab bar at a 45-degree angle next to the toilet to assist with sit-to-stand transfers."
• A written report with diagrams or photos showing the proposed modifications. This helps you visualize the changes and serves as a reference during the construction phase.
• A cost estimate for each recommended modification, with options for phasing if the full scope is not immediately affordable.
• A timeline estimate for the work, including any permit requirements that could affect the schedule.

If a CAPS professional offers to do an evaluation but cannot provide a written report with visuals, or if the evaluation feels rushed and superficial, consider it a red flag. The evaluation is the foundation of the entire project — it should be thorough enough that you feel confident in the recommendations.

Your Next Steps After Hiring

Once you have selected a CAPS-certified contractor and signed a contract, the project moves into the execution phase. Here is what to expect and how to stay involved:

• Permit process: The contractor should handle all permit applications. Ask for a copy of the approved permits before work begins. This protects you if an inspector later questions the work.
• Communication plan: Establish a regular check-in schedule — daily or weekly, depending on the project's complexity. Know who to call with questions or concerns.
• Timeline expectations: The contractor should provide a start date and an estimated completion date. Be prepared for minor delays due to material availability or weather, but flag any significant deviations immediately.
• Final walkthrough: Before making the final payment, walk through the completed work with the contractor. Test every modification — open doors, use grab bars, operate the stair lift. Confirm that everything matches the written scope of work.
