If you’ve ever walked into a client’s home and felt that quiet moment of “I know this matters, but I’m not sure I know enough to do this well,” you’re not alone. Home modifications sit at a strange intersection in our field — everyone agrees they’re important, but almost no one gets trained in them properly.
The Gap Nobody Talks About
Most entry-level OT programs cover adaptive equipment, maybe a lecture on universal design, and perhaps a fieldwork rotation that touches on home safety. That’s often the extent of it. What’s missing is the deeper layer: how to conduct a truly comprehensive home assessment, how to translate clinical findings into buildable modification recommendations, how building codes and accessibility standards intersect with client goals, and how to navigate Medicare and funding documentation so recommendations actually get implemented instead of stalling in paperwork.
The result is a profession full of therapists who care about home safety and aging in place, but who were never given the technical, regulatory, or design vocabulary to practice at the level their clients need. That gap doesn’t show up on paper — it shows up in the field, when a therapist recommends a ramp with the wrong slope, misses a critical bathroom clearance measurement, or can’t confidently justify a modification to a funding source.
A Familiar Model: Lessons from Driving Rehabilitation
If this idea of “entry-level skills versus advanced skills” feels unfamiliar in the home modifications space, it shouldn’t feel unfamiliar in OT more broadly. Our profession has already built and formalized this exact tiered model in another practice area: driving and community mobility.
AOTA and national practice guidance describe a spectrum of driving rehabilitation practitioners, generally organized into three tiers: the OT-Generalist, the OT-Advanced practitioner, and the OT-Advanced Specialist (New Brunswick Association of Occupational Therapists [NBCOT], 2021). Every OT graduates with generalist-level skills, meaning they can screen for driving-related risk factors, recognize red flags, and know when a client needs a more specialized evaluation. Advanced practitioners build on that foundation with additional training to conduct more structured, standardized assessments. Advanced Specialists, often holding a formal credential like the Certified Driver Rehabilitation Specialist (CDRS), handle the most complex cases, including comprehensive behind-the-wheel evaluations and vehicle modification recommendations (Canadian Association of Occupational Therapists, n.d.; NBAOT, 2021).
Crucially, this model was never built to suggest that every OT should become a driving specialist. It was built so that every OT would know the boundaries of their own competency and recognize when a case calls for someone with more advanced training. A generalist who tries to manage a complex driving case alone, without referring appropriately, isn’t just under-resourced, they’re operating outside the model the profession itself created to keep clients safe.

Why This Matters More Than Ever
Demand for home modification expertise is only growing. The aging-in-place movement isn’t slowing down, home health and community-based OT referrals for fall prevention keep climbing, and families and case managers are actively searching for therapists who can speak fluently about ramps, grab bars, bathroom redesigns, and multi-level home access — not just recommend a shower chair and move on.
Therapists who invest in advanced training in this niche aren’t just filling a knowledge gap for themselves. They’re positioning themselves as the go-to expert in a specialty area where genuinely qualified providers are still rare. That scarcity is an opportunity.
What “Advanced” Actually Looks Like
Advanced training in home modifications goes well beyond what a general OT curriculum offers. It typically includes:
- Comprehensive, structured home assessment protocols that go beyond a basic checklist
- Deep knowledge of accessibility codes, universal design principles, and how they apply in real (not idealized) homes
- Skill in evaluating and recommending complex modifications — ramps, stair lifts, bathroom redesigns, kitchen adaptations, multi-level access
- Clinical reasoning that connects modifications to functional outcomes: safer transfers, reduced fall risk, increased independence, and caregiver relief
- Practical knowledge of funding sources, Medicare documentation requirements, and how to write recommendations that actually get approved and implemented
- Confidence to collaborate with contractors, architects, and case managers as a credible clinical voice in the modification process
That last point matters more than people realize. Without this training, therapists often defer to contractors on design decisions that should be clinically driven. With it, therapists become the ones contractors call for guidance.
Closing the Gap With CHAT
This is exactly the gap the Certification in Home Accessibility Training (CHAT) program was built to close. Rather than leaving therapists to piece together this knowledge from scattered CEUs, general falls-prevention courses, or trial and error in the field, CHAT is designed as a structured path to genuine competency in home modifications — covering assessment, design reasoning, funding navigation, and real-world case application.
And this fall, CHAT is launching its first cohort-based format. Instead of working through the material solo, participants will move through the program together, with structured pacing, live discussion, and peer accountability — the kind of learning environment that tends to produce deeper skill retention than self-paced courses alone. For therapists who’ve been meaning to build this expertise but haven’t had the structure or accountability to follow through, a cohort removes that friction.
The Bottom Line
Home modification work sits right at the intersection of clinical skill, practical problem-solving, and real impact on people’s ability to stay safely in their homes. It’s a specialty area where advanced training isn’t a “nice to have” — it’s the difference between offering surface-level recommendations and becoming the therapist that families, case managers, and contractors trust to get it right.
If you’ve felt that gap in your own practice, the upcoming CHAT cohort is a good place to start closing it.
