Building permits, zoning and land rules in Putnam County, Florida

Unincorporated Putnam County requires a building permit for new construction, additions, remodeling, changes of use, accessory structures and other listed work regulated by the statewide Florida Building Code^1,2. Repair or maintenance affecting less than 10% of a building's nonstructural elements is a listed exception, but all work still must comply with the code¹. A qualifying owner-builder may build a residence or farm outbuilding for personal use, with code, zoning and inspection duties still applying^7,9. Palatka requires city and county processing for building permits; Crescent City has its own building-permit requirements^10,11. In Pomona Park, mobile-home work requires preliminary town approval and applicable county building permits¹². Septic permitting in these municipalities stays with the Florida Department of Health in Putnam County^4,13.

The Putnam County Building Department handles county permitting and inspections and can be reached at (386) 329-0307¹⁴. The office is at 2509 Crill Ave. in Palatka and is open Monday through Friday from 8:30 a.m. to 5:00 p.m¹⁴.. Putnam County publishes permit applications online and uses an online permitting portal, while application materials can require plans, ownership evidence, zoning information, septic pre-approval, site-work permits and outside-agency approvals¹⁵. Putnam County publishes a countywide fee schedule for the fiscal year beginning October 1, 2026¹⁶. Building permit fees vary by project; the older schedule calculates fees using construction type, occupancy, square footage under roof and a percentage modifier¹⁷. Consult the current schedule and ask the Building Department for the project-specific charge rather than budgeting from older deposits or rates^14,16.

Putnam County's Land Development Code governs unincorporated land; Palatka, Crescent City, Interlachen, Pomona Park and Welaka administer their own zoning^{3,18,19,20,21,22}. Septic permitting in those municipalities remains with the Florida Department of Health in Putnam County⁴. In unincorporated Putnam County, minimum lot area depends on district, use, utilities and subdivision rules; PUD zoning has no fixed minimum lot area, but its ordinance, development agreement and other dimensional rules still apply³. An R-1 lot has a 15,000-square-foot minimum area with 25-foot front, 10-foot side and 20-foot rear setbacks^3,23. Newly created lots generally need one-half acre and 100 feet of width for private well and septic, or one-quarter acre and 75 feet of width for central water and private septic; the stricter applicable standard controls³. Manufactured homes are allowed in AG, R-2 and RMH districts⁶. Ask Planning & Zoning to confirm the parcel's district and utility requirements⁶.

A septic permit is required before constructing, repairing, modifying, abandoning or operating an onsite sewage treatment and disposal system in Putnam County²⁴. Florida's Department of Environmental Protection implements the applicable statewide rules, while the Florida Department of Health in Putnam County continues local septic permitting and inspection⁴. A construction permit is valid for 18 months and may receive one 90-day extension; a repair permit is valid for 90 days²⁴. Contact Environmental Health at 386-326-3240 or visit 2801 Kennedy St. in Palatka²⁵. Only 5.2% of Putnam County soils are rated without severe limitations for a conventional septic drain field, so arrange the site evaluation before fixing the house location or assuming a conventional system will fit²⁶. We could not confirm a separate off-grid sanitation path; ask Environmental Health what permitted system can serve the proposed use²⁵.

Temporary RV shelter in unincorporated Putnam County requires a temporary use permit in AG, AE, RE, R-1, R-1A, R-1HA, R-2, R-2HA or RMH districts⁵. Land-clearing occupancy is limited to 60 days without outside utility connections; construction occupancy requires principal-dwelling permits and septic hookup, starts with 6 months and may extend to a maximum setup period of 12 months⁵. Extreme-hardship occupancy is limited to 6 months⁵. A small conventional, site-built or modular home may qualify as an accessory dwelling in unincorporated single-family residential, Agriculture or Agriculture Estate districts, but only for guests or family without a fee³. Only one accessory unit may serve the primary home; the parcel generally needs at least one-half acre unless central water and sewer serve it and district dimensional requirements are met³. The accessory unit must be at least 375 square feet and cannot exceed either 75% of the primary home's enclosed area or 2,000 square feet³. We could not confirm a general minimum size for a principal home; ask Planning & Zoning about the proposed dwelling^3,6. Mobile homes and park models cannot serve as guest houses³.

1. Ask Planning & Zoning to confirm whether the parcel is in unincorporated Putnam County and identify its zoning district, future land use, minimum lot size, setbacks and lot-coverage limit before designing the site^3,6,23.

1. Arrange the required septic site evaluation and permit with the Florida Department of Health in Putnam County if the site will use onsite sewage²⁴. Obtain the required well permit too if the property will use a private well⁸.

1. Secure a Putnam County driveway permit for a connection to the county road system; a state-road connection instead needs the separate state permit¹⁵.

1. Obtain a Floodplain Development Permit before the construction permit if the site is in Flood Zone A or AE¹⁵.

1. Submit the building application and supporting approvals to the Putnam County Building Department, using the owner-builder route only if the project qualifies^7,15.

1. Schedule applicable inspections as work proceeds⁹.

1. Apply for the certificate of occupancy or final inspection, as applicable, before occupying work authorized by a Development Permit or Development Order³.

Confirm the parcel's municipal jurisdiction, zoning district, future land use, legal lot status, minimum lot size, setbacks and lot-coverage limit before treating it as buildable^3,6,23. Minimum lot area is not countywide: the applicable district, proposed use, utilities and subdivision rules can change the requirement, and the stricter standard controls where requirements conflict³. Check road access too, because every connection to the Putnam County road system needs a driveway permit and an existing driveway may need owner-funded upgrades to current standards¹⁵. Review flood exposure before placing the home: construction in Flood Zone A or AE needs a Floodplain Development Permit before the construction permit¹⁵. A private well needs a permit for construction, repair or abandonment⁸. For carrying costs, the effective property-tax rate is about 0.8%, the median annual property-tax bill is about $1,196, and the typical home value is about $219,440²⁶.
