Getting Repairs

If a landlord does not meet the duties imposed by the Landlord Tenant law or the local housing codes or the rental agreement or if there are conditions which materially affect health and safety, then... a tenant may give the landlord a written notice to correct the condition. This notice must be in writing and delivered to the person or at the place where the tenant normally pays rent. Tenant should keep a copy of this notice.

If the landlord fails to correct the condition within a reasonable time, not to exceed 30 days, then the tenant may deposit his/her rent with the Clerk of Courts, or may apply to the Court for an order to compel the repairs, or may terminate the rental agreement.
