Summary
Polk County has no separate tiny-home ordinance. A tiny house on a permanent foundation must meet the Florida Building Code and the zoning district's standards; a mobile home is only allowed as a temporary medical-hardship residence under strict LDC limits, not a casual second dwelling.
Mobile homes may be permitted as a temporary special exception in all residential districts, on the same lot or parcel as an existing principal residence, in cases of medical hardship... The mobile home may not be approved on a lot or parcel less than 12,500 square feet or 50 feet in width.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 109 | Land Development Code: Supplement 12).
Full Breakdown
Polk County's LDC does not create a distinct tiny-home category, so a tiny house is regulated by its structure type. A site-built or modular tiny home must meet the Florida Building Code and the district's lot-area and setback rules in Table 2.2, and individual mobile homes are only allowed where 'Mobile Homes, Individual' is a permitted or conditional use per Table 2.1. The main way to add a temporary extra dwelling is LDC Section 206.J: a temporary mobile home for a medical hardship on the same lot as an existing home, on a parcel of at least 12,500 square feet or 50 feet wide, not in the front yard, with approvals valid one year and renewable while the hardship continues.
Violations & Fines
Placing a tiny home or mobile home as a second dwelling against the district use rules, or keeping a medical-hardship mobile home after the hardship ends, violates the LDC; the hardship unit must be removed within 60 days.
