How Palm Bay Handles Accessory Structures: A Practical Guide
Palm Bay maintains 104 local ordinances across all categories, and 6 of those deal specifically with accessory structures. Here is a breakdown of what the city actually requires, what is prohibited, and where Palm Bay falls on the strict-to-permissive spectrum compared to other cities.
Garage Conversions
Palm Bay lets homeowners convert an attached garage to living area only if replacement parking is provided on-site and the new space connects directly to the house.
Key details: Garage type: Must be attached to principal structure. Access: Must connect directly to home's living area. Parking: Required spaces replaced on lot. Codes: Building and fire codes still apply.
Converting a garage to living space without providing the replacement required parking on the lot, converting a detached garage under this provision, or completing the conversion without meeting building and fire code requirements.
ADU Rules
Palm Bay allows one accessory dwelling unit per single-family lot where the zoning district's Table 173-1 permits it, capped at 800 square feet or half the main house, plus required parking.
Key details: Max per lot: One accessory dwelling unit. Size cap: 800 sq ft or 50% of home. Minimum size: 200 sq ft. Parking required: 1-2 spaces.
Building an ADU that exceeds the size cap, skips required parking, or is added in a district where Table 173-1 doesn't permit it is a zoning violation subject to enforcement.
ADU Impact Fees
Palm Bay charges impact fees on an accessory dwelling unit as if it were a separate mobile home, not folding it into the fee already paid for the principal house.
Key details: Fee category: Treated as mobile home unit. Governing section: § 174.003(K). Applies to: Every approved ADU.
Occupying an ADU before paying the required mobile-home-rate impact fee can delay or block issuance of the certificate of occupancy.
ADU Owner Occupancy
Palm Bay requires the property owner to actually live in either the main house or the accessory dwelling unit: you can't build an ADU purely as a rental with an absentee owner.
Key details: Owner-occupancy required: Yes, in one of the two units. Governing section: § 174.003(B). Separate sale: Prohibited.
Renting out both the principal dwelling and the accessory unit with no owner living on site violates § 174.003(B) and can trigger code enforcement action against the property.
Tiny Homes
Palm Bay allows tiny home development only within planned unit developments, letting an all-tiny-home PUD use a one-acre minimum site instead of the standard five-acre PUD minimum.
Key details: Governing section: § 173.063, Palm Bay Code. Where allowed: PUD zoning only. Minimum site, all-tiny-home PUD: one acre. Standard PUD minimum: five acres.
Placing a tiny home outside an approved PUD, or below the one-acre threshold required for an all-tiny-home PUD, is not a permitted use and will be denied at plan review.
Compared to other cities, Palm Bay takes a harder line on tiny homes. The enforcement and penalty structure reflects that.
Shed & Carport Rules
Sheds in Palm Bay can't exceed half the home's living area, and sheds, gazebos or pergolas over 120 square feet need a 10-foot rear setback, 6-foot side setback, and 10 feet on corner lots.
Key details: Size cap: 50% of home's living area. Rear setback (>120 sf): 10 feet. Side setback (>120 sf): 6 feet. Corner lot setback: 10 feet.
Exceeding the 50% living-area cap or building a shed over 120 square feet without meeting the rear, side, or corner setback is a zoning violation subject to code enforcement action.
The Bottom Line
Palm Bay's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Palm Bay is broadly strict or permissive.
These rules come from Palm Bay's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
