In 2023, Florida passed a new state law that significantly changes how Accessory Dwelling Units (ADUs) are regulated. This law, often referred to as the "ADU bill," requires local governments to allow ADUs on properties zoned for single-family residential use. Key provisions include that ADUs must be at least 500 square feet and cannot be subject to owner-occupancy requirements, meaning you can rent them out even if you do not live on the property. However, local ordinances in areas like Miami still impose specific zoning rules, setbacks, and parking requirements.
