Final answer:
In Michigan, unlicensed real estate sales and unauthorized property renovations are illegal under the Michigan Occupational Code. Late rent payment and failure to provide tenant references, while not covered by the Occupational Code, may still have civil repercussions.
Step-by-step explanation:
In the state of Michigan, engaging in unlicensed real estate sales is illegal and considered a violation of the Michigan Occupational Code. Performing real estate transactions without the appropriate license contradicts professional standards and state regulations governing the real estate industry.
This is designed to protect consumers from fraudulent dealings and ensure that all real estate brokers and salespersons meet the necessary qualifications and adhere to professional ethics.
Likewise, engaging in unauthorized property renovations may also be a violation, especially if it involves structural changes to a property without the proper permits or contravenes any local building codes or zoning laws. Such actions can endanger the safety of inhabitants and neighboring properties.
On the contrary, late rent payments and failure to provide tenant references are generally not violations of the Michigan Occupational Code but may have civil consequences according to the lease agreement or other relevant housing laws.
