Yes, in most areas, you can rent out your converted garage ADU either as a long-term rental or a short-term rental, depending on local regulations. However, there may be restrictions based on zoning laws or homeowner association rules. Some cities require that the property owner live on-site, while others may have limitations on the length of time the unit can be rented or restrictions on short-term rentals like Airbnb. Always check with local ordinances to ensure compliance before renting out your ADU.
