I'm a bit floored. There are all kinds of obscure laws — or would-be laws — pertaining to real estate that can throw practitioners for a loop. But three points of discussion came up during Wednesday's sessions at the REALTOR® Party Convention and Trade Expo in Washington, D.C., that made my draw drop.

1. Your Website Discriminates Against People With Disabilities

You could make every physical accommodation for people with disabilities: ramps and elevators in your office, barrier-free entrances to homes you have listed, etc. And yet, despite all of that, you could still run into a legal problem — because your website isn't optimized for use by people with hearing or visual impairments.

More and more businesses are getting mired in lawsuits because their online videos don't have closed captioning for the deaf, or their websites don't use software that can turn text into audio for the blind. Though there are no specific regulations on this, said Glen D. Kimball and Martin J. McAndrew, partners at law firm O'Connor Kimball LLP, they expect that the law will reflect the need for these online components in the near future.

"Laws governing accommodation for the disabled are always expanding," McAndrew said. "Now we're going beyond talking about opening physical doors for people with disabilities — it's about providing access to information. The courts are still grappling with this physical versus non-physical issue."
