First-Floor Suites Arranged in Largo
A ground-floor bedroom and bath in Largo is an addition, not an ADU, so the city's 2025 ADU rules leave it alone.

Largo's ADU ordinance, and why it stops short of this job

Largo's Comprehensive Development Code (Sec. 16.14, Ord. 2025-01) does not permit ADUs in the Coastal High Hazard Area or the Special Flood Hazard Area, caps an ADU at 800 square feet or 50 percent of the principal home's living area, whichever is less, requires either the main home or the ADU to be owner-occupied, and requires a notarized affidavit that the unit, if rented, will be rented only at an affordable rate as defined in F.S. 163.31771.

Florida Statute 163.31771 defines an accessory dwelling unit as an ancillary or secondary living unit that has a separate kitchen, bathroom and sleeping area, within the same structure or on the same lot as the primary dwelling.

Why Largo's first-floor page is short
We keep this page short because Largo's own rules are about ADUs and garages. A bedroom and bath added on the ground floor, with no kitchen of its own, is neither, so the city's flood-zone ADU ban does not stop it. The flood rules for additions still apply on a hazard-area lot. We arrange the work with a vetted Florida-licensed contractor, as anywhere else in Tampa Bay.

The one Largo question for a downstairs suite
Tell the contractor whether the parcel is in a flood hazard area, and keep the kitchen out of the plan. That keeps the job clear of Largo's ADU section and leaves the flood test for additions as the rule to meet.

A Largo downstairs suite question
Does Largo's ADU ban stop a first-floor bedroom addition?
Not if the addition has no kitchen of its own. The ban applies to accessory dwelling units, which Florida defines by a separate kitchen, bathroom and sleeping area.
