County profile
Partially sourcedDuval County
Duval County now has a first-pass Florida county-office routing anchor from the State of Florida county directory. Tiny home, RV, off-grid, container-home, ADU, water, septic, access, floodplain, wetlands, and building-permit feasibility should still be confirmed through county staff, municipality checks, subdivision rules, private covenants, and parcel-level research before purchase.

County Profiles Do Not Approve Parcels
This profile summarizes county-level signals. Before relying on a parcel, verify current rules with planning, zoning, building, environmental health, water, road, fire, title, and local professionals.

What Still Needs Confirmation
This profile has official source coverage for county-level discovery, but it still needs stronger current county-office confirmation before being promoted to verified. Treat it as a shortlist candidate, then confirm the exact parcel and intended use with local offices.
Exact intended use
Ask about the specific structure, RV or camper occupancy plan, water source, septic path, access road, and development sequence.

Best Fit
Pros
- https://www.coj.net/ provides a first-pass Florida county-government routing anchor listed from the State of Florida county directory
- Florida onsite sewage, private well, DEP, and building-code resources support statewide due diligence
- this record can be compared against climate, solar, broadband, public-land, tax, and land-market layers already collected
- Florida source route now separates county contact from DEP/DOH onsite sewage, Florida Building Code, Chapter 163 planning, zoning, or local permit follow-up.
Cons
- this is a county-directory routing pass, not a county-office confirmation or zoning interpretation
- county source depth still needs office confirmation and topic-specific planning, zoning, permit, floodplain, or health-department route review
- floodplain, wetlands, coastal construction, hurricane exposure, city jurisdiction, subdivisions, covenants, utilities, well/septic feasibility, and local code enforcement can change the parcel-level answer

Verified county-level discovery scores
Alternative Housing Notes
Tiny Homes
Use the listed Florida county, DEP/DOH onsite-sewage, Florida Building Code, and local planning/permitting routes to confirm tiny-home placement, zoning district if applicable, minimum dwelling or construction standards, permits, utilities, wastewater, floodplain exposure, and municipal or subdivision restrictions for the exact parcel.
RV Living
Long-term RV occupancy should be confirmed with the county or local jurisdiction because zoning, sanitation, camping, nuisance, floodplain, utility, coastal, and subdivision rules can differ by parcel.
Off Grid
Off-grid feasibility should be checked against Florida OSTDS rules, well or water access, road access, floodplain and coastal exposure, fire response, electric service choices, and any county or municipal permitting rules.
Container Homes
Container-home feasibility depends on zoning use classification, Florida Building Code review, structural documentation, wind/flood standards, foundation standards, inspections, and whether the jurisdiction treats the project as modular, manufactured, or site-built construction.
ADUs
ADU rules are often city, county-zoning-district, floodplain, coastal, or subdivision specific in Florida; verify accessory dwelling, guest house, and secondary residence rules before relying on county-level signals.
Land Affordability
sourced
Sourced market snapshot
Source: LandWatch snapshot from June 12, 2026. LandWatch county page snapshot. Active listing count is from the county page title/metadata; medianAcrePrice is the median asking price per acre from visible page listing data (25 nonzero sampled listings), not a full-market median or appraisal.
Population Context

Sourced Census estimate
Population uses 2024 U.S. Census county estimates. Density is computed from county land area in the imported GeoJSON boundary data.
Water and Septic
draft
Parcel-level verification needed
Water
Water availability in Duval County is parcel-specific. Florida private-well and environmental-health resources are useful starting points, but buyers should verify public-water access, private well feasibility, contamination risk, testing, saltwater intrusion, wetland limits, and subdivision-specific rules.
Septic
Septic feasibility in Duval County requires parcel-level review with the county health department or Florida DEP/OSTDS authority, including site evaluation, soils, setbacks, floodplain, water-source separation, system design, installation, repair rules, and county-specific requirements.
Climate, Utilities, and Access

Broadband source: Census Reporter ACS 2024 5-year table B28002 snapshot from 2024. Broadband score is a county-level ACS household broadband subscription proxy, not parcel-level service availability. Score is based on the percentage of households with broadband of any type.

Red Flags
- do not treat this Florida source pass as parcel approval
- verify jurisdiction, zoning district, building permits, sanitation, water well or water service, legal access, wetlands, floodplain, storm surge, wind load, fire response, covenants, easements, subdivision restrictions, and whether the parcel is inside a municipality, special district, conservation area, or private development

County-level profile reviewed; parcel-level confirmation still required
This profile is currently marked partially sourced. It is ready for county comparison and early research, but legal claims and parcel-specific decisions should still be verified against county code, planning offices, and local experts.
County FAQ
Frequently Asked Questions
Is Duval County a good county for alternative living?+
Duval County has a Freedom Score of 39, which makes it useful for county-level discovery. Treat that score as a shortlist signal, then verify zoning, building, water, septic, access, and covenant rules for the specific parcel.
Can you live in a tiny home in Duval County?+
Duval County has a tiny home score of 2/5. That score does not approve a tiny home by itself; it means the county is worth researching through planning, zoning, building code, sanitation, and parcel-specific rules.
Can you live in an RV on land in Duval County?+
Duval County has an RV living score of 1/5. RV rules often depend on duration, construction status, sanitation, water, zoning district, and whether the land is inside a subdivision or municipality.
Is Duval County good for off-grid living?+
Duval County has an off-grid score of 2/5. Off-grid feasibility still depends on legal access, septic or OWTS approval, water options, fire risk, winter access, and whether a lawful dwelling can be permitted.
How affordable is land in Duval County?+
Duval County has a land affordability score of 20/100 based on the current county-level dataset. Use this for comparison only, because actual parcel prices can vary by road access, utilities, terrain, water, covenants, and listing quality.
Who is Duval County best suited for?+
Based on the current profile, Duval County is best suited for Northeast Florida and First Coast rural land screening, Florida county-office due diligence, floodplain-aware parcel-level alternative living research. The best fit can change once you narrow from county-level research to a specific property.
What should I verify before buying land in Duval County?+
Before buying, confirm zoning, building permits, legal access, road maintenance, water rights or well eligibility, septic feasibility, wildfire requirements, floodplain issues, mineral rights, and any HOA, POA, subdivision, or covenant restrictions.
