Landlords must comply with various federal and state regulations to ensure legal compliance. At the federal level, laws such as the Fair Housing Act prohibit discrimination based on race, religion, national origin, or other protected categories. Landlords must also provide habitable living conditions for tenants. State regulations can differ significantly, including laws governing security deposits, lease agreements, and eviction processes. Neglecting these regulations can lead to litigation and financial penalties for landlords. Therefore, it is crucial for landlords to familiarize themselves with both federal and state laws to manage their rental properties effectively.
