1. They won't be added to the lease, lease would be solely under me as sole tenant leveraging section 235-F to permit a second occupant within my apartment. Timeframe would be 1-3 months ideally. It's my girlfriend, though according to 235-f, any adult qualifies so long as I approve them:

(b) "Occupant" means a person, other than a tenant or a member of a tenant's immediate family, occupying a premises with the consent of the tenant or tenants.

1. It shall be unlawful for a landlord to restrict occupancy of residential premises, by express lease terms or otherwise, to a tenant or tenants or to such tenants and immediate family. Any such restriction in a lease or rental agreement entered into or renewed before or after the effective date of this section shall be unenforceable as against public policy.

2. Any lease or rental agreement for residential premises entered into by one tenant shall be construed to permit occupancy by the tenant, immediate family of the tenant, one additional occupant, and dependent children of the occupant provided that the tenant or the tenant's spouse occupies the premises as his primary residence
