Does Apalachicola have zoning, and what does it mean for lots and houses?

Yes. Apalachicola has its own zoning code, with districts named R-1, R-2, R-3, R-4, C-3 and R/C, administered with a planning and zoning board². The City of Apalachicola Planning & Community Development office handles special exceptions and variances⁹.

The rules change by district. In the R-1 single-family district, a lot needs at least 6,000 square feet, 60 feet of width and 100 feet of depth¹⁰. A single-family house in R-1 must be at least 800 square feet, and the same minimum applies in R-2, R-3 and R-4⁶. R-1 caps lot coverage at 40 percent and height at 35 feet¹¹, and requires a front setback of at least 15 feet and a rear setback of at least 25 feet for the main building¹².

The figures above describe R-1 only¹⁰. Ask the planning office which district a parcel sits in before relying on them.

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

Inside Apalachicola city limits, the City of Apalachicola Building Department administers building permit applications¹. The department says Section 105 of the Florida Building Code requires permits for most construction-related work¹, and it lists a set of small residential items that need no permit.

A separate permit is required for electrical work, plumbing, signs, roofing, pools, furnaces, boilers, heaters, tanks, air conditioners and tree removal¹. For new construction, mobile homes, sheds, decks, fences and accessory structures, the city says to consult the Planning Department before permits can be issued¹.

Contact the Building Department at 850-653-7592 or buildingdept@cityofapalachicola.com¹. The city says a permit request generally takes 3 to 5 business days¹. The city's rules for building inspection beyond flood-area manufactured homes were not confirmed, so ask the Building Department what inspections your project needs.

How do septic permits work inside Apalachicola?

Septic permits for Franklin County, including addresses in the city, are managed by the Florida Department of Environmental Protection since January 2, 2025, and the county health department still performs permitting and inspection work for septic tanks³. The DEP Northwest District office can be reached at 850-595-8300¹³.

Florida requires a permit to install, repair, modify or abandon an onsite sewage system, and a site evaluation decides whether the lot suits one¹⁴. Franklin County's soils are demanding: only about 0.4% of soils rate as not limited for a conventional drain field, so expect an engineered system on lots without sewer¹⁵.

Inside the city, development in the Special Waterfront district must connect to the municipal water and sewer system¹⁶. Whether a particular lot has city sewer available, and whether the city adds its own septic rules, we could not confirm; ask the City of Apalachicola Building Department. Well permits come from the water management district or its delegate, not the city¹⁷.

Can you live in an RV, mobile home or tiny home in Apalachicola?

In most residential districts, no. Apalachicola's code lists travel trailers as prohibited in the R-4 mixed use residential district, and also in R-1, R-2 and C-3⁴. The same code prohibits mobile homes and house trailers in R-4⁴.

Mobile and modular homes built to the Florida Building Code are allowed in the R-3 mobile home residential district⁵. Mobile homes and house trailers are prohibited in R-1, R-4 and C-3, and on vacant lots or residential yards in R-2⁵. A mobile home park in R-3 needs a special exception, a site plan, a stormwater plan and a central water and sewer hookup⁵.

In flood hazard areas, a recreational vehicle may be placed temporarily for fewer than 180 consecutive days, or if it is licensed and highway-ready⁴. We did not find a tiny home provision in the city's code, so ask the planning office how a tiny home on a foundation would be classified.

Building a home in Apalachicola: the steps, in order

1. Confirm the parcel's zoning district and setbacks with the City of Apalachicola Planning & Community Development office at planning@cityofapalachicola.com⁹.
2. Check whether the lot is in a rated flood zone; residential development there must be elevated or floodproofed⁸.
3. Consult the Planning Department before applying for a permit for new construction, as the city requires¹.
4. Settle the sewage question: city sewer where it is available, or a septic permit through the state DEP and county health department³.
5. Apply to the Building Department. For work costing $2500.00 or more, a certified copy of the Notice of Commencement goes in with the application¹.
6. Owners may act as their own contractor on a home they will occupy, with the owner supervising the work on site⁷.
7. Schedule inspections through the Building Department clerk¹.

What stays with Franklin County, and what to check before you buy in Apalachicola

The city's rules apply only inside Apalachicola. Land outside city limits falls under Franklin County, so for rural parcels use the Franklin County page rather than this one.

Septic permitting is a state and county matter for every address in Franklin County, city or not³. Before buying, check flood zone status, since Apalachicola requires elevation or floodproofing in rated flood zones⁸, and check sewer availability for the lot.

Franklin County's effective property tax rate is about 0.6% of value¹⁸. Windows and doors matter too: the city's Building Department says all glass in new or replacement windows and doors from 2026 forward must be impact resistant¹.

Watch-outs

• Impact-resistant glass is required in all new or replacement windows and doors for work permitted from January 1, 2026 onward, per the city's Building Department¹.
• The city lists RVs and travel trailers as prohibited in most residential districts, so confirm the parcel's district before parking one⁴.
• We could not confirm the city's septic rules, certificate of occupancy process or permit fee schedule; ask the City of Apalachicola Building Department at buildingdept@cityofapalachicola.com¹.
• Fraudulent emails claiming to be from the city planner ask for planning and zoning fee payments; the city says fees cannot be paid by email⁹.
