Your place may also need to be updated to comply with ADA standards which may or may not get expensive depending on the layout of everything.

Some tenants are also using ADA to have a pet so adhering to ADA rules in developing pet policies has become another legal aspect we are now responsible to understand, so I think it's kind of getting more difficult to have an across the board absolute "NO" on pets.

Even federal ADA guidelines allow a "service animal" to be excluded if it is not housebroken. 

My local phone company ad a service called " remote call forwarding".

Potentially my second small Multi-Family in very hot market (Ada County Idaho, basically Boise and surrounding suburbs). 

Commercial projects require sprinklers in all units, ADA (in 1-unit), a civil survey, DRA, etc., etc.

I am ADA compliant meaning that every square inch of the property is inspected by both state and local officials to make sure its not a problem.

I put together a case study on my longest running ad a few months ago if you want to check it out.

I was the hospital compliance officer for the ADA, Rehabilitation Acts, and Civil Rights Acts.
