I've seen several ads where the landlord states emphatically that he's not accepting any programs, some specifically mention no section 8.
Some ads don't say anything about it at all until you contact them and ask and then they say they don't take section 8. If it's not illegal, why don't they post it on their ad to save one the trouble of calling them?
Is this illegal in New York? I know it's illegal in Massachusetts for a landlord to refuse to rent to you if you have a Section 8 voucher or ask if they take section 8.
