ADU rules in Largo

The ADU 'can be constructed within a primary structure on the property, an attached unit, or a freestanding unit on the same lot as the primary residence or business.' Detached ADUs must be placed in side or rear yards (never front yards, buffer areas, or recorded easements), must match the principal structure's setbacks and architectural style, may not exceed the principal structure's height or two stories (whichever is lower), and must meet Florida Building Code separation distances.

Both internal (within the primary structure) and attached ADUs are expressly contemplated alongside freestanding units. An attached ADU's maximum height calculation, including the garage or primary unit below, is two stories, and a separate exit/entrance and separate street address are required.

Height is separately capped: a detached ADU may not exceed the principal structure's height or two stories, whichever is lower; an attached ADU counts the garage or primary unit below toward a two-story maximum.

On residential lots, 'either the primary dwelling unit or the ADU must be occupied by the property owner,' and the required notarized affidavit includes an acknowledgment of owner occupancy requirements. The parallel standards for ADUs accessory to non-residential uses (Sec. 16.14.4.B) contain no owner occupancy clause.

Table 9-2 (Vehicle Parking Requirements) lists 'Accessory Dwelling Unit (ADU): No Min if property meets parking requirements for the primary use and if not then 1/ADU, No Max.' Sec. 16.14.4.A(13) and B(11) cross-reference these minimums.

ADUs on residential and non-residential properties 'are permitted subject to' listed objective standards; required submissions are a boundary survey, building permit, related permit inspections, and (for residential lots) the notarized ADU affidavit. No conditional use or public hearing step appears in Sec. 16.14. ADUs must be accessory to a use allowed under Tables 6-1 and 6-2.

The affidavit is a required submission before permitting, not an after-the-fact enforcement tool. The CDC also has a separate short-term vacation rental section (Sec. 15.18); its interaction with ADUs was not verified this session.
