Short-term rentals (STRs), locally referred to as "vacation rentals," are legal in Contra Costa County, California, but they are subject to strict regulations enforced by the Department of Conservation and Development. To operate legally, property owners must obtain a short-term rental permit, with an application fee of $380, and complete documentation, including proof of primary residence and site plans. The types of properties that thrive include urban apartments, single-family homes, and even rural cabins, making the market flexible for both tourists and business travelers. The STR market benefits from proximity to attractions such as the East Bay Regional Park District and various vineyards, thus catering to a mix of leisure and professional visitors. STRs are particularly popular in unincorporated areas, and the county imposes a 10% transient occupancy tax on these rentals. Permit renewals are required annually, and failure to comply can lead to fines. The overall market environment is favorable as long as rules are followed, and regional government authorities actively engage with the STR community to ensure regulations are meant to foster compliance, emphasizing community well-being.
