Does Dunedin, Florida have zoning, and what does it mean for RVs, tiny homes and lot size?

Yes. The City of Dunedin regulates land uses through its own zoning districts for land inside city limits¹. Pinellas County's zoning rules cover only unincorporated land, so the county's lot-size and setback tables do not apply inside Dunedin⁹.

Camping is prohibited in Dunedin city parks unless the city permits it in an organized program⁷. That rule is about parks, not private lots, and we could not confirm whether Dunedin allows living in an RV or tiny home on a private lot; ask Community Development before you buy.

An accessory dwelling unit in Dunedin must have the owner living in either the main house or the unit, with no more than 3 occupants⁵. Short-term rentals are treated as a commercial use in residential districts⁶. Minimum lot sizes and setbacks by district are not confirmed here; the zoning district for a specific parcel decides them.

Do you need a building permit in Dunedin, and who issues it?

Yes for most work. Dunedin's Community Development office states that building permits are required for most work on residential buildings and structures². The city issues them, not Pinellas County; the county building department serves unincorporated land only¹⁰.

Florida's statewide building code applies in the city, so plans are reviewed against the Florida Building Code, 8th Edition (2023)⁸. Owners building their own one- or two-family home to live in can act as their own contractor, but the owner must still personally sign the permit application¹¹. We could not confirm Dunedin's own owner-builder steps or fee schedule on its pages; call the permit office.

How do septic permits work inside Dunedin?

Septic permits for Pinellas County come from the Florida Department of Health in Pinellas County, not from the city's building office³. Inside Dunedin, though, a septic system is rarely the answer. Houses and buildings used for human occupancy next to a street with public sewer must connect within 90 days of official notice when the sewer is within 200 feet, and abandoned septic tanks must be pumped and filled or removed at the owner's expense⁴.

Pinellas County also limits onsite systems to areas where sewer connection is not required and soils suit them¹². Florida requires a site evaluation for a septic permit¹³, and USDA rates 0% of Pinellas County soils as not limited for a conventional drain field, so expect an engineered system on any lot outside sewer service¹⁴. We could not confirm whether the city allows new septic systems at all; ask the health department and Dunedin Community Development.

Building a home in Dunedin: the steps, in order

1. Confirm the parcel is inside Dunedin city limits and find its zoning district with Community Development².
2. Check whether public sewer abuts the lot, since connection is required when sewer is close⁴.
3. Apply for the building permit online through the city; call the permit office with questions².
4. Build to the Florida Building Code, 8th Edition (2023)⁸.
5. Pass inspections and get a certificate of occupancy; the city's own inspection steps were not confirmed, so ask the permit office².

What stays with Pinellas County, and what to check before you buy in Dunedin

Septic permits stay with the Florida Department of Health in Pinellas County³. The county's building and zoning rules apply to unincorporated land; for a parcel outside city limits, see the Pinellas County page.

Before you buy, check sewer availability, flood zone and the parcel's zoning district. Pinellas County's typical home value is about $371,631¹⁵, and the county's effective property tax rate is 0.7%¹⁶.

Watch-outs

• Dunedin's building-permit fee schedule, owner-builder steps and zoning district tables were not confirmed; call Community Development at the permit office before you rely on a figure².
• Dunedin's code requires sewer connection where public sewer is within 200 feet of an occupied building, and septic tanks that are abandoned must be pumped and filled or removed⁴.
• Pinellas County's zoning tables apply only in unincorporated areas, so they do not set lot sizes or setbacks inside Dunedin⁹.
