St. Petersburg & Pinellas County Zoning Guide
St. Petersburg is a dense, established market — ADU construction is the primary tiny home pathway. Florida’s 2025 ADU law significantly eased permitting across Pinellas County.
| Build Type / Zone | St. Pete / Pinellas Rules |
|---|---|
| ADU in St. Petersburg (City) | ✅ ADUs permitted on most single-family lots. Florida SB 184 (July 2025) streamlined Pinellas County ADU approvals, reducing local red tape. The law mandates ADU approval timelines and removes several local restrictions. St. Pete offers dedicated ADU guidance through the city’s development services portal. |
| Pinellas County (unincorporated) | ✅ ADUs by-right under 2025 state law in residential zones. Unincorporated areas include Largo, Seminole, and St. Pete Beach adjacent markets. Pinellas is one of FL’s most densely developed counties — ADUs are the primary path for new tiny homes. |
| THOW in St. Petersburg | ⚠ THOWs require licensed RV park placement for permanent living within the city. Pinellas County has 15+ licensed RV parks within 20 miles of downtown St. Pete. Not permitted on standard residential lots. |
| High Wind Zone (HVHZ-adjacent) | ⚠ St. Pete’s coastal location means high-wind-zone construction standards apply. Impact-rated windows and roofing required for new construction. Adds $3,000–$10,000 versus interior Florida builds depending on proximity to coast. |
| Tax Rate (Pinellas County) | ⚠ Pinellas County property tax rates run approximately 17–20 mills combined, among FL’s higher combined rates. ADU rental income can offset the carrying cost — a key factor in ADU ROI calculations for St. Pete buyers. |
St. Petersburg Tiny Home Builder FAQ
Can I build an ADU in my St. Petersburg backyard?

Where can I place a tiny house on wheels near St. Pete?
Within St. Petersburg city limits, THOWs must be placed in licensed RV parks — Pinellas County has 15+ licensed parks within 20 miles of downtown. Popular options include Fort De Soto Park campground, Clearwater Beach RV parks, and several Largo-area campgrounds. For permanent THOW living closest to the progressive THOW policy in Florida, Brevard County (Melbourne, Palm Bay) is the recommended market.
What is the best type of tiny home for St. Pete?
For St. Pete specifically, foundation ADUs are the most practical and financially attractive option. ADU rental income in St. Pete’s competitive housing market ($250,000–$450,000 median) generates strong rental ROI — 1BR ADUs rent for $1,200–$1,800+/mo. Park model THOWs in Pinellas County RV parks are a strong second option for buyers not tied to a specific neighborhood. Tell us your situation and we’ll recommend the right build type.
