Should landlords have the right to refuse to rent to people with children?

Can landlords refuse to rent to children? With a few exceptions that will be described shortly, the answer is no. The general rule in all 50 states is that you cannot discriminate against renters or applicants on the basis of family status due to the Fair Housing Act.

Yes.  It's their property, so they should have the right to choose their tenants, kids, dogs, smokers, non-smokers - all of it.

Landlords own their property, so they have the right to establish their own rules.

yep he can , after all he stated no kids , there the rules and you signed to obey the rules .

They already have that right, as being exempted from the federal Fair Housing Act, if:

1. They own no more than three single family houses and they do not use a real estate professional to find tenants.*

2. They own a 1-4 unit building and live in one of the units.#

3.  Their development is an officially-designated '55 or over' community.

* This exemption does not apply in Pennsylvania, which has the Human Relations Act.

#  This exemption exists under Pennsylvania's HRA only for 1-2 unit buildings that the owner lives in.

Of course they should be allowed to do that. There are rental communities that are specifically designed for certain tenants--and some landlords just don't want children at all--or pets. Some apartments or houses just aren't suitable for children. It's up to a LANDLORD whether or not he or she wants tenants with children. Your children aren't allowed in BARS--or Strip clubs--or adult bookstores--so why do you think they must be allowed in any rental property?  

Yes, for sure if the property is "senior housing"   Which means that it's for people over 55 yr old.  There may also be some laws that limit the number of people who will be living in a house or apt.  

Can't say whether they should but they generally can't, at least not in the USA as its illegal to discriminate based on Familial status.  I guess its a good idea to make that generally illegal. It you made it legal to discriminate based on that, then they want to start discriminating based on other stuff and its a slippery slope where the whole thing ends.

Sure, and you should market it "no children." 

They do now as if a landlord refuses to rent to a tenant ( with or without children) they don't need to give a reason although I assume you mean  'legally' refuse

As a landlord I prefer tenants with pets than tenants with children as children are hard on a property and can be disruptive locally however that depends on the parent/s
