In the USA renting is largely a state law matter. Some states are very landlord friendly, but others, such as California, are considerably more tenant friendly. For example late fees are illegal in California and you can basically get a pro se judgment easy peasy if a landlord even attempts to get you to sign a lease with a late fee clause, let alone collect one. You can also withhold rent to pay for services the landlord should have provided, and so on. Anyhow I'm not a lawyer and this isn't legal advice, but if you're in California learn your rights.
