A friend of mine has been looking to rent an apartment or a house for over three months now. What's the problem? She has a dog. This dog isn't just a "pet", it's been a part of the family for 16 years. For three whole months there has not been a single solitary place for rent in her price-range in the school district where she needs to live that will allow pets.
Now I understand that landlords ASSUME that pets can be a problem - whether that problem be damaging doors, woodwork, etc, or barking, or nasty smells. But there are OTHER issues that landlords don't seem to take into consideration:
People with pets will pay higher rents. They don't move as often. They increase security at the building. And more... http://www.spca.bc.ca/welfare/campaign-issues/pets-in-rental-housing.html
Every renter I know with a pet is extremely aware of the fact that if their pet damages the property they will be booted from the rental. They are far more careful than people with pets who own their own homes.
We've all heard that owning pets is beneficial to your health, as well. Why should landlords object to that?
I think it's ridiculous that a person who is obsessively clean and tidy, who pays her rent on time and who loves her dog can't find a decent place to live because "We do NOT allow pets!"
