Backyard ADUs like this are being built across Dade City — here's how to do it right.
What Dade City's zoning may allow for an ADU
Dade City allows a rentable accessory dwelling unit by right in its RS-1, RS-2, RS-3, and planned-development districts, capped at 33% of the principal home or 800 sq ft, whichever is less. Owner-occupancy is not required; the only limit is that the ADU cannot be sold separately.
Zoning allowance
An accessory dwelling unit is allowed by right (not a special exception) in the RS-1, RS-2, RS-3 and PD districts, one per lot, subordinate to a single-family home (LDR §4.4.4(A), Ord. 2024-05).
Size limits
No ADU 'shall exceed 33 percent of the size of the habitable floor area of the principal dwelling unit, or 800 square feet, whichever is less' (LDR §4.4.4(A)(3)).
Lot + setbacks
Setbacks, lot coverage, and minimum lot size for an accessory dwelling vary by zoning district. Confirm the exact figures with the city's planning department.
Height + coverage
Height and lot-coverage limits vary by zoning district. Confirm current limits with local planning.
Parking
Parking requirements for an accessory dwelling vary by district; typically one additional space. Confirm with local planning.
Rental / occupancy
The unit may be rented — the code imposes no owner-occupancy or rental prohibition. The only restriction is that the ADU may not be sold apart from the principal dwelling (LDR §4.4.4(A)(7)).
Permit process
An accessory dwelling is permitted through the city's standard zoning-review and building-permit process. Contact the local planning or building department for current requirements.
