Hi - Although you are living with a difficult situation, you should be very careful before breaking lease. Houston area apartments are very strict about enforcing leases to the full extent of the law.
If you break your lease without legal authority, you could be responsible for 1) Accelerated rent - the total mount due for all remaining months left on the lease, and 2) Reletting fees that the apartment will charge for having to re rent your unit, 3) Pius additional fees for move out or damages as stated in the lease.
Also, you should know that many apartment complexes communicate with each other about past tenants. If you break your current lease, you could find it difficult to obtain another apartment in the Houston area.
Your credit rating could also be affected if the landlord decides to sue to collect unpaid rent, and you are unable to satisfy the judgment.
That said, you may be able to legally get out of your lease because of the conditions of the property. Particularly if the safety issues constitute negligence on the part of the landlord. Also, if you relied on a functioning gate when you entered into the lease, the lack of a functioning gate may be grounds for lease termination. Most leases are complex and you will need to read it very carefully to determine if you can escape without penalty.
I recommend you contact The Texas Office of the Attorney General
, Consumer Protection Division for advice.(NNN) NNN-NNNN
Also, the local Houston Apartment Association specializes in assisting people in you situation.(NNN) NNN-NNNN
These two organizations would be best equipped to tell you whether the conditions would allow you to break your lease. Also, you can submit complaints to each respective agency.
Stay safe and good luck!
