Pinellas Park FAQ
Are detached ADUs allowed in Pinellas Park?
Detached accessory dwelling structures are evaluated under Section 18-1530 and the property's zoning district. Confirm eligibility with the Community Development Department before applying for a building permit.

Short-term residential rentals are largely preempted by Florida Statute 509.032, but local zoning, registration, and building-occupancy rules still apply. Verify with city Planning before listing.

Yes in NS, NT, and NSM districts that allow ADUs under Sec. 16.50.010, provided your lot meets minimum size, the ADU stays within 40 percent of combined floor area, and you obtain building and zoning permits.

No. Sec. 16.50.010 and Ordinance 509-H require ADUs to share the primary residence's mailing address rather than receive a separate address from the post office.
