Lead Base Paint
Many houses and apartments built before 1978 have paint that contains
high levels of lead (called leadbased paint). Federal law requires that
individuals receive certain information before renting, buying, or renovating
pre-1978 housing: Landlords have to disclose known information on lead-based
paint and lead-based paint hazards before leases take effect. Leases
must include a disclosure about lead-based paint.
HUD has Guidelines for the Evaluation and Control of Lead-Based Paint
Hazards

Security Deposits
Landlords are to use their own discretion for security deposits, however
it is prohibited for the amounts to be in excess of local or state law
and for amounts charged by the owner to unassisted tenants.
