If you have been searching for an accessible home, you will learn very quickly that all the big name real estate sites like Zillow, Trulia, and Redfin have no accessible features filter.
As a Realtor, I have access to these types of filters through the MLS. I’m able to set up searches that will update you when homes with roll-in showers, ramps, elevators, etc. come on the market. Make sure whoever you’re working with sets up one of these searches for your unique needs.
Now, don’t think that this is going to be a perfect search. The search is only as good as the agents who are entering the details of their listings. Most agents have no idea what most of these accessible features are. For example, I have seen where a home has a steep ramp up to the door, and the agent checked the box for a wheelchair accessible ramp. Most wheelchair users know that an ADA-legal ramp has to have a foot of ramp for every inch of elevation change. Agents don’t usually know these things though, so don’t be surprised when the accessible features listed in a home are not actually there. The listing photos should give you some indication as to the accuracy of the listing details, so be sure to check those out.
