Property Specifications for Accessory Dwelling Units (ADUs) in Florida
Accessory Dwelling Units (ADUs) are secondary housing units located on the same lot as a primary residence. They can be a valuable addition to your property, providing additional rental income, space for family members, or increased property value. Here are the key property specifications to consider for ADUs in Florida.
Size and Square Footage
- Maximum Size: ADUs typically range between 400 to 1,200 square feet, depending on local zoning laws and the size of the primary residence. In some areas, the size of the ADU may not exceed a certain percentage of the primary home’s square footage.
- Minimum Size: The minimum size is often dictated by building codes and local ordinances, usually around 150 to 400 square feet.
Height and Stories
- Height Restrictions: ADUs are usually limited to one or two stories. Height restrictions vary by municipality, but they often must be lower than or equal to the height of the primary residence.
- Setbacks and Distance: There are often specific requirements for how far an ADU must be from property lines and other structures. Common setbacks range from 5 to 15 feet.
Design and Appearance
- Architectural Style: Many jurisdictions require that the ADU match the architectural style and materials of the primary residence to maintain neighborhood aesthetics.
- Entrance: The entrance to the ADU may need to be separate from the main house and not visible from the street.
utilities and services
- Independent Systems: ADUs usually have their own separate utilities, including water, sewer, electricity, and sometimes gas. However, depending on local regulations, they can also share utilities with the primary residence.
- Parking: Some areas require additional off-street parking spaces for ADUs. The number of spaces varies, but one additional space per bedroom in the ADU is common.
Occupancy and Use
- Owner-Occupancy Requirement: Some jurisdictions require that the property owner live in either the primary residence or the ADU. This is to prevent the property from being used solely as a rental.
- Rental Restrictions: There may be regulations on how the ADU can be rented out, including minimum rental periods (e.g., no short-term rentals under 30 days).
Permitting and Zoning
- Zoning Compliance: ADUs must comply with local zoning laws, which dictate where ADUs can be built. They are often allowed in residential zones but may be restricted elsewhere.
- Permits: Building an ADU requires obtaining the necessary permits from local building and planning departments. This process includes submitting plans, passing inspections, and adhering to building codes.
Accessibility and Safety
- Building Codes: ADUs must meet all local building codes and safety standards, including those for plumbing, electrical, and fire safety.
- Accessibility: While not always required, making the ADU accessible for individuals with disabilities can increase its usability and appeal.
