Most people reading this guide won’t build their home with their own hands, and that’s fine. Many readers said they couldn’t build because of a back injury, a disability, or simply not having the skills. The key is finding the right help and being very clear about what you need.

“I know myself well enough to know I cannot build my own home.”

— Jane, Tiny House Talk reader

Who can help

Professional How they help How to find one
Occupational therapist (OT) Assesses how you move and what you need, measures you and your equipment, and recommends specific features. Some specialize in home modifications Ask your doctor for a referral for a home safety or home modification evaluation. Depending on your coverage and medical need, it may be partly covered by insurance or Medicare; ask before you book
Certified Aging-in-Place Specialist (CAPS) A designation from the National Association of Home Builders (NAHB) for builders, remodelers, designers, and others trained in aging-in-place design Search the NAHB directory and select the CAPS designation for your state
Architect or designer Draws a layout that works for your needs and meets code Look for experience with accessible or universal design; ask to see examples
Builder Builds it Ask for accessible homes they’ve built and talk to those owners
Local building department Tells you which code applies and what’s required City or county website; many accept questions by email
Area Agency on Aging / Center for Independent Living Local resources, sometimes home modification programs or funding help Search “Area Agency on Aging” or “Center for Independent Living” plus your county

Combining an OT with a builder works well

An OT knows your body; a builder knows construction. When the two talk to each other (or when you bring the OT’s written recommendations to the builder), you get a home that fits you. Ask the OT to write their recommendations down with specific measurements.

Want to do this on paper?

The printable PDF of Tiny Without the Ladder has fill-in worksheets for this step, including:

  • Bathroom & Kitchen Accessibility Checklist
  • Builder Accessibility Questions

They come with all five guides in the Going Tiny Toolkit.

Questions to ask a builder

Worksheet 5 (Builder Accessibility Questions) has a full list you can print. Here are the most important:

  • Have you built homes for people who use wheelchairs or have mobility needs? Can I talk to one of those owners?
  • Can you build a curbless shower in this house? How do you handle the drain?
  • Will you install blocking for grab bars in all bathroom walls? Can you show me where on the plan?
  • What is the clear width of each doorway, measured with the door open?
  • How high is the floor above the ground, and what are my options for a ramp or lift?
  • Which standard or code will this be built to (IRC, Appendix AQ, RV standards, ANSI A119.5, HUD code, none)? Will it be inspected or certified?
  • What happens if a dimension in the finished house doesn’t match what we agreed on?

Put it in writing

Don’t rely on “Sure, we can do that.” Every accessibility feature you need should be written into the contract or the specifications, with specific measurements. For example:

Example contract language (adapt with your builder)

“All interior doorways shall provide a minimum 32-inch clear opening measured with the door open 90 degrees. The bathroom shall include a curbless shower with a minimum interior of 36 by 60 inches, a handheld shower on a slide bar, a pressure-balancing valve, and 2x solid wood blocking in all bathroom walls from 30 to 40 inches above the finished floor. The toilet seat height shall be between 17 and 19 inches. A 60-inch turning space shall be provided in the bathroom and the main living area, as shown on the attached plan.”

Attach a marked-up floor plan. Then check the measurements yourself before the walls are closed and again at the final walk-through. If phone calls are difficult, ask to handle all communication by email, so you have everything in writing.

Buying an existing home

If you’re buying a used tiny house, park model, or manufactured home, bring a tape measure and Worksheet 3. Measure door widths, hallway widths, the shower entrance, the toilet height, and the height of the floor above the ground. Ask what’s behind the bathroom walls (it’s rare to find blocking in a used home, but you can add it during a remodel). Ask whether you can modify the home, and ask what it would cost. Sometimes a home that’s almost right can be adapted; sometimes the width alone rules it out.

Be wary of “accessible” as a sales word

“ADA-style” or “accessible” in an ad doesn’t guarantee anything in particular. Measure it yourself. If a seller can’t tell you the clear door width or show you the bathroom turning space, that tells you something.

About money

Accessible features don’t always cost much more, especially when planned from the start. A curbless shower, wider doors, a lower entry, and a ramp do add cost. Some states, nonprofits, and veterans’ programs offer help with home modifications for people with disabilities or older adults. Your Area Agency on Aging or Center for Independent Living is a good first call. For budgeting and financing, see The Tiny House Money Plan.

A last word from me

So many of you wrote that you were afraid of making the wrong choice. I understand that. But you don’t have to get everything right at once. Know your needs, get the size right, plan the bathroom and the entry carefully, and write it all down. Whether you end up in 200 square feet, 700 square feet, or a safer version of the home you already have, you’ll have made a choice that fits your life. That’s the whole goal. — Alex
