Ok, thanks for that information. The fact that the house is poorly insulated and not energy efficient wouldn't give you legal grounds to terminate the lease. Neither would any unpermitted structures unless they are a danger to you. And unpermitted work is between the city and the owner..
But if they didn't give you any information regarding lead based paint, that is a violation of federal law, the EPA and HUD laws specifically, and could give you grounds to terminate the lease if you do so promptly.
You could notify the landlord or these specific violations:
* Failure to provide information/pamphlet.
* Failure to disclose presence of lead-based paint or lead-based paint hazards.
* Failure to disclose to each agent the presence of any lead-based paint, or lead based paint hazards, and the existence of any available records or reports.
* Failure to provide any records or reports.
* Failure to include, as an attachment to (or within) the contract, the Lead Warning Statement.
* Failure to include, as an attachment to the contract, a statement by the lessor disclosing the presence of known lead-based paint, or lead-based paint hazards.
* Failure to include as an attachment, or within the contract, a list of any records or reports available to the lessor that pertain to lead hazard information, or the failure to indicate that no such list exists.
* Failure to include in the contract for lease a statement by the lessee affirming receipt of the information and the lead hazard pamphlet.
* Failure to include in the contract as an attachment, a statement by one of more of the agents involved in the transaction, that the agent has informed the lessor or the lessor's obligations and that the agent is aware of his duty to ensure compliance.
* Failure to include in the contract for lease, signatures of the lessor, agent, and lessee certifying to the accuracy of their statements, as well as dates.
* Failure to retain a copy of the completed disclosure records for no less than three years from the completion date of the lease.
Then you could threaten to sue and file a complaint with the EPA and HUD and ask them to investigate if they do not release you from the lease in writing and return any deposit to them immediately.
