Need to know if any code violations, handicap regs for the area.

From Fair Housing--It's Your Right In the Sale and Rental of Housing: No one may take any of the following actions based on race, color, national origin, religion, sex, familial status or handicap: Refuse to rent or sell housing ...Perhaps "source of income" is covered elsewhere, but its not a protected class for federal fair housing.

Wider doors and handicap ramps can also be included in the cost of rehabilitation.26.

I've only had the experience in altering owner occupied properties for persons with handicaps but I see this as a woman who broke the lease and brought in a person who very well may be suffering from a handicap without allowing you any opportunity to see if your property is legally able to accomodate a person with a handicap.

I would not charge a fee for any kind of service animal for a handicapped renter and as Tim W mentioned, I wouldn't charge it for an officer with a K9 partner who rented from me.

BUT if a handicapped person is selected to rent the property and asks for an accommodation that a  tub be added, then you must consider this accommodation, and if it is reasonable you must do it. 

A tenant with a criminal record is handicapped for life when it comes to rental housing.

Possibly one that is handicap accessible. 

We  had handicap signs and access lines painted to "removed barriers for access". 

Anyway, I feel that my biggest handicap is my income.
