Since you are a minor, the landlord can refuse to rent an apartment to you.  The reason is that the lease is a contract and a minor would not be able to sign a contract.  If you were allowed to sign the lease and if the landlord filed a lawsuit against you for rent, you would have a defense of being a minor.  When you turn 18, this will no longer be an issue.  If your spouse is 18, your spouse could sign the lease.  If your spouse is under 18, your parent or your spouse's parent could sign the lease.
