In recent years, California has seen a significant increase in the construction of Accessory Dwelling Units (ADUs), also known as guest houses or mother-in-law units. In 2023, ADUs made up one in every five new homes built, a notable rise from just one in ten only three years ago.

Starting July 1, 2024, California landlords can no longer request security deposits exceeding one month's rent, with small landlords owning no more than two properties exempt from this rule.
