Any commercial space that is open to the public must meet ADA requirements, from the door threshold height, ramps, bathrooms, bath sinks even counters that may be put in for checkout ( that's tenants responsibility when they outfit the space).

As a former tax accountant myself, I congratulate you for making the switch and joining the commercial real estate space!
