Manatee County Revises Accessory Dwelling Unit (ADU) Regulations: What You Need to Know

Manatee County Revises Accessory Dwelling Unit (ADU) Regulations: What You Need to Know

Manatee County has recently changed its Accessory Dwelling Units (ADUs) regulations, providing more flexibility for homeowners and property developers. These changes, formalized under Ordinance No. 25-08, aim to address past challenges with the permitting process while aligning with modern housing trends and community needs. Here’s a breakdown of these changes and how they could impact you.

1. Expanded Size Limits

   • The previous maximum size cap of 750 square feet for ADUs has been eliminated. Now, ADUs can be up to 80% of the size of the primary residence. For example, a homeowner with a 1,500-square-foot house can now build an ADU up to 1,200 square feet.

   • Properties zoned for agricultural use (A or A-1) previously capped ADUs at 1,000 square feet. This restriction has also been removed.

2. Flexible Rules for Multiple Structures

   • Under the new regulations, the number of subordinate structures (ADUs or guest houses) permitted on a property is now based on acreage:

     • Less than 5 acres: One subordinate structure (either an ADU or a guest house).

     • 5 to 19.99 acres: Up to two subordinate structures, which could be a combination of ADUs and guest houses.

     • 20 or more acres: Up to three subordinate structures in any combination of ADUs and guest houses.

   • This update provides larger parcels with increased flexibility to meet growing family needs or rental opportunities.

3. Distinguishing ADUs from Guest Houses

   • The main difference between an ADU and a guest house lies in functionality:

     • ADUs include a full kitchen (e.g., stove/oven) and are intended for full-time living.

     • Guest houses are designed for temporary stays and lack a full kitchen.

4. Improved Clarity and Consistency

   • The ordinance addresses conflicting language in previous codes, resolving practical difficulties faced by applicants. It also removes outdated restrictions, such as the “whichever is less” clause, which often limits ADU size unnecessarily.

5. Applicability and Implementation

   • These changes apply to all new ADU applications and any pending applications as of January 14, 2025. The updates aim to foster harmonious development while preserving the county’s character.

The updates reflect a growing recognition of the benefits ADUs bring to communities. ADUs provide additional housing options, enable multi-generational living, and can serve as rental income sources. By aligning regulations with practical needs, Manatee County has taken a step toward addressing housing demands while supporting property owners' flexibility.
