You can choose to disallow pets, but you cannot deny a service animal. You can choose to not permit smoking in your rental property. We comply fully with the Fair Housing Act. This means that you cannot choose to disallow anyone that is a member of a protected class under the act. If you have additional questions on the specifics of the Fair Housing Act, please Google Fair Housing Act or go to http://portal.hud.gov/hudportal/HUD?src=/program_offices/fair_housing_equal_opp/FHLaws/yourrights.
