I'm asking for my parent's as tenants. They want to know if they are allowed under the ADA to put grab bars in the shower/tub. And then they want to know if they have to pay the full cost or if the landlord needs to pay any of installation. My parents moved into this apartment in mid December. Have never had a landlord before. They have already told me some things the landlord told them that contradicts with ADA law - such as they can't have a service dog - so they are worried what will happen if they modify the bathroom.
