The Contractor Credential Most Homeowners Have Never Heard Of
Hiring a general contractor for an aging-in-place remodel is a bit like hiring a general practitioner for a highly specific medical issue, they might do fine, but there's a specialist trained specifically for this exact situation, and most homeowners never think to ask if one's available.
A Certified Aging-in-Place Specialist, CAPS, is a designation created by the National Association of Home Builders specifically for contractors, designers, and remodelers who complete additional training in the unique technical and design requirements of building for older adults and people with mobility limitations. It's not a general contractor's license, it's an additional credential layered on top of one, meaning a CAPS-certified professional still needs their standard state contracting license or design credentials, the CAPS designation specifically signals additional specialized training beyond that baseline.
What that additional training actually covers goes well beyond just "knows how to install grab bars." CAPS coursework includes building codes and standards specific to accessibility, the physiological and functional needs that change with aging (vision, mobility, balance, cognitive considerations), how to design and build solutions that address those needs without looking clinical or institutional, and how to talk with clients and their families about sensitive changes in a way that respects independence rather than treating the homeowner as a problem to be solved.
Here's why that training actually matters in practice, not just on paper. A general contractor without this background might install grab bars that meet basic structural requirements but places them somewhere that doesn't match how a person with limited mobility actually moves through a bathroom. A CAPS-trained professional considers the entire sequence of movement, how someone approaches the shower, where their hand naturally reaches for support, how they'd need to pivot to sit down, and designs around that actual use pattern rather than a generic placement.
CAPS-certified professionals also tend to have a broader awareness of the full toolkit available for a given problem, rather than defaulting to whatever their business typically installs. Someone specializing purely in walk-in tubs will naturally recommend a walk-in tub. A CAPS professional evaluating the same bathroom might recommend a curbless shower instead if that better fits the specific person's needs, since their training covers the full range of solutions rather than one product category.
Finding a CAPS-certified contractor in your area is straightforward: the National Association of Home Builders maintains a searchable directory of certified professionals, and it's worth using that directory as your starting point rather than searching generically for "accessibility contractor" or "bathroom remodeler," since the directory specifically filters for the credential.
A few questions worth asking any contractor, CAPS-certified or not, before hiring them for this kind of project: how many aging-in-place or accessibility-specific projects they've completed, whether they can walk you through how they'd approach the specific movement patterns in your home rather than just listing products they'd install, and whether they involve an occupational therapist or similar professional in the design process for more complex cases, some of the best outcomes come from a contractor and a healthcare professional working together on the actual layout, not the contractor working in isolation from any input about how the person actually functions day to day.
It's worth being clear about what CAPS doesn't guarantee: certification reflects training completed, not a guarantee of quality craftsmanship or fair pricing, which are separate things worth vetting through the standard channels, references, reviews, licensing verification, regardless of whether a contractor holds this specific credential. CAPS narrows your search to people with relevant specialized knowledge, it doesn't replace the rest of your due diligence.
If a CAPS-certified professional isn't available in your specific area, that's not a dead end. Ask any contractor you're considering directly whether they have specific experience with accessibility-focused projects, and ask to see photos and get references specifically from that kind of work rather than their general portfolio. The underlying goal, someone who genuinely understands the difference between a bathroom that looks accessible and one that actually functions well for the specific person using it, matters more than the certification itself, even though the certification is a reliable shortcut to finding that expertise when it's available nearby. That distinction is the one worth holding onto throughout the entire hiring process, from the first phone call to the final walkthrough. A contractor who genuinely gets it will welcome those questions rather than treating them as an inconvenience or a sign you don't trust their work right from the start. That openness is often the clearest early signal of who's actually right for the job.
