OCGuide: Dangerous Clauses

Beware! Certain lease clauses can cause you significant problems if enforced. You should be extremely wary about signing a lease (or should attempt to renegotiate its terms if a reasonable explanation isn't forthcoming from the landlord) if any of the following or similar provisions appear in the proposed lease:

that the premises are acceptable "as they are" (see security deposits).
that the Landlord is not liable for repairs.
that all improvements to premises become the property of the landlord (without being reimbursed by the landlord for those improvements).
that no one else will live with you.
that you agree to pay possible extra, unspecified rent.
that you agree to obey rules not yet written in the lease.
that the Landlord has the right to enter the premises at any time.
that the premises may be shown to prospective buyers or renters at any time (rather than only during a specified period).
that the Landlord (owner) is permitted to cancel the lease if the property is sold.
that the Landlord (owner) has the right to repossess the premises at any time.
that the Landlord has the right to cancel the lease if "dissatisfied" with your behavior or if your behavior is "immoral".
that you will pay any attorney's fees, including the landlord's, if incurred in connection with your tenancy.
that you waive your right to a jury trial in the event of a court action arising from your tenancy.
that you are forbidden to have overnight guests.
that you lose your tenancy if you are gone for any length of time.
that you waive your right to sue.
