Dear [Landlord's name], I hope this letter finds you well. I am writing to bring an urgent matter to your attention regarding the building codes in our rented property located at [property address]. It has come to my attention that there are several violations of building codes, which are impacting the health, safety, and habitability of the premises. It is imperative that you take immediate action to remedy these issues. Firstly, [describe the specific building code violations affecting health and safety]. These violations directly pose a threat to not only my well-being but also that of other tenants. As per Pittsburgh Pennsylvania regulations, it is your responsibility as the landlord to ensure that the property is safe for occupancy. I kindly request that you bring the property up to code, ensuring proper ventilation, functioning smoke and carbon monoxide detectors, and fixing any structural issues that may pose a potential hazard. In addition, the untenantable condition of the premises is gravely concerning. [Describe the specific untenantable conditions resulting from the landlord's failure to comply with building codes]. These problems, such as [list examples such as leaks, mold growth, electrical issues], make it extremely difficult to live comfortably and safely in the property. I cannot stress enough the urgency of these repairs, as failure to address these issues not only violates our lease agreement but also compromises my rights as a tenant. Under Pittsburgh Pennsylvania law, tenants have the right to a safe and habitable living environment. With that in mind, I kindly demand that you take immediate action to remedy these violations. I request that you provide me with a written commitment outlining a specific timeline for repairs to be completed. Furthermore, I expect for an inspection to be conducted upon completion to ensure that all violations have been properly addressed. Failure to comply with these demands will leave me with no choice but to pursue further action, which could include filing a complaint with the relevant housing authorities, withholding rent until repairs are completed, and potentially seeking legal counsel. I sincerely hope that we can address these concerns promptly and amicably. I value my tenancy in your property and believe that by working together, we can ensure a safe and habitable living space for all residents. Please respond to this letter within [reasonable timeframe] to acknowledge receipt and provide your action plan for resolving these issues. Thank you for your attention to this matter. I look forward to a swift resolution. Sincerely, [Your Name] [Tenant's Contact Information]
