Does Monticello, Florida have zoning, and what does it mean for mobile homes and RVs?

Yes. Monticello adopts and administers its own zoning districts inside city limits under Chapter 54 of its Land Development Regulations¹. The R-1 district covers low-density single-family housing, and the Agriculture district allows low-intensity agricultural and residential use⁴.

Mobile homes. In the R-1A district, a mobile home is permitted without a variance if the lot or lots provide 5,000 square feet of usable land, though setbacks and flood-area installation rules still apply⁶. In the Agriculture district, a mobile home is allowed only if the owner lives on the property and the zoned acreage exceeds 5 acres; the city also bars rezoning from R-1 to agricultural solely to place one⁷.

RVs. A travel trailer or mobile home may serve as a temporary residence in Monticello only while construction on the premises is actively underway, and use beyond 12 months needs city council approval⁸. We could not confirm any rule for long-term RV living outside construction; ask the City Planner.

Accessory dwellings. Monticello allows one accessory dwelling unit per lot in the R-1, R-1A and Agriculture districts, on lots that have or will have a principal single-family home⁹. We could not confirm a tiny-home rule.

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

Yes. Inside Monticello, the city requires written approval from City Hall before any construction, remodeling or development begins, including modular and manufactured structures². The city then issues a Development Permit, and the applicant takes that permit to the Jefferson County Building Department, which issues the building permit².

So two offices are involved: the City Planner handles the first step at 245 S. Mulberry Street⁵, and the Jefferson County Building Department handles the second at 445 West Palmer Mill Road¹². The county describes the same two-step order for its own jurisdiction: a Development Permit from Planning, then building permits¹³. Florida's Building Code applies statewide¹⁴.

We could not confirm the city's fee schedule, a separate owner-builder process or the city's own inspection rules, so ask the City Planner before you apply.

How do septic permits work inside Monticello?

Septic permits for every address in Jefferson County come from the Florida Department of Environmental Protection, which took over Jefferson County permitting and inspections from the Florida Department of Health on January 2, 2025³. The city does not issue them.

Applicants submit DEP4015 pages 1 and 2, a building floor plan and a site evaluation, which a private evaluator can perform before you submit¹⁵. Local ordinances can add to state requirements¹⁵.

The county's soil data matters here: about 12.3% of Jefferson County soils rate as not limited for a conventional drain field, so many lots need a site evaluation and sometimes an engineered system¹⁶. Whether a given lot inside Monticello must connect to city sewer we could not confirm; ask City Hall about water and sewer connections. Florida law requires an existing septic system to connect within 365 days after written notice that public sewer is available¹⁷.

Building a home in Monticello: the steps, in order

1. Call the City Planner at 850-342-0153 to confirm the zoning district and what your project needs⁵.
2. Submit two copies of a site plan and construction plans to the City Planner².
3. Expect planning agency review for single-family plans, and historic district board approval if the property is in the historic district².
4. Take the resulting Development Permit to the Jefferson County Building Department for the building permit².
5. Apply for a septic permit through the Florida Department of Environmental Protection and complete a site evaluation¹⁵.
6. If the lot is in a flood hazard area, expect inspection and a lowest-floor elevation certificate¹¹.
7. Florida owners acting as their own contractor must personally sign the building permit application and supervise the work onsite¹⁰.

What stays with Jefferson County, and what to check before you buy in Monticello

The county's rules apply to unincorporated land, not city lots; see the Jefferson County page for land outside Monticello. Even inside the city, building permits, inspections and septic involve the county or the state, as above².

Before you buy, check four things. First, confirm the zoning district; we could not confirm minimum lot size, setbacks or home size for the single-family and Agriculture districts, so ask the City Planner⁵. Second, check flood zones, because city rules require elevation certification for lowest floors in flood hazard areas¹¹. Third, if you plan to subdivide, note that Jefferson County requires approval under its Land Development Code before new deeds are recorded¹⁸. Fourth, a driveway onto a county road needs a county Road & Driveway Connection Permit¹⁹.

Jefferson County's effective property tax rate is 0.7%²⁰.

Watch-outs

• Search results often mix up Monticello, Florida with Monticello in Illinois, Utah and elsewhere; confirm the 850 area code and Jefferson County, FL address before relying on a page⁵.
• A mobile home in Monticello's Agriculture district needs the owner living on the property and more than 5 acres zoned; the city may not rezone from R-1 just to place one⁷.
• A travel trailer or mobile home used as temporary housing during construction needs city council approval after 12 months⁸.
• We could not confirm the city's permit fees, minimum lot sizes, setbacks or water and sewer connection rules; ask the City Planner at City Hall before you buy or build⁵.
