    *   Strategies for setting competitive rental rates
    *   Marketing the ADU to potential tenants
    *   Managing the ADU as a rental property (tenant screening, lease agreements, property maintenance)
    *   Discuss legal and ethical considerations of renting an ADU
6.  **Pros and Cons:** Weigh the advantages and disadvantages of building an ADU for rental income.
7.  **Conclusion:** Summarize the key points and offer advice to homeowners considering building an ADU.
