Do you need a building permit in Nassau County, Florida?

Yes. Unincorporated Nassau County requires a permit from the local Building Department before repairs or new construction, although the available county material does not exhaustively identify every project-specific exemption¹. The department issues permits, reviews plans and inspects residential and commercial work throughout the unincorporated county¹⁰. Florida's statewide base code is the Florida Building Code, 8th Edition (2023), with later commission updates incorporated into the rule¹¹. Permit fees vary because the enforcing agency adopts the applicable reasonable fees¹². An owner-builder exemption is available under the cited Florida statute, but the owner must personally appear at the Nassau County office and sign the application; the exemption does not waive applicable building requirements¹³. Ask the Building Department whether the exact repair, outbuilding or other proposed work is exempt before starting.

Who is the Nassau County building department, and how do you reach them?

The Nassau County Building Department, at 96161 Nassau Pl. in Yulee, handles building permits, plan review and inspections; call (904) 530-6250 or email [email protected]¹⁰. The Nassau County Planning Department works from the same address and interprets the Land Development Code and comprehensive plan; call (904) 530-6320 or email [email protected]¹⁴. For written verification of a parcel's zoning status, Development Services accepts zoning-certification requests for a $42 fee per parcel and asks applicants to allow up to 14 days; call (904) 530-6249 or email [email protected]¹⁵. Flood-zone questions go to Floodplain Management at 904-530-6410 or [email protected]⁷. These county contacts cover unincorporated land; incorporated municipalities may administer their own local rules².

Does Nassau County have zoning?

Yes. Nassau County's Land Development Code and zoning atlas apply to unincorporated land; a municipality may administer separate rules inside its limits². The county publishes its zoning districts through the code and GIS zoning atlas, but the allowed uses and dimensional standards still depend on the parcel's district¹⁶. Minimum lot and yard requirements are district-specific, and a proposed lot split must also satisfy the applicable density and frontage rules⁵. Building setbacks, density and height likewise vary by zoning designation⁶. For a parcel-specific answer, ask Planning to identify the district and applicable code provisions, or request a zoning certification letter from Development Services¹⁴¹⁵. Do not treat a large or rural-looking tract as unrestricted: its district controls uses and dimensions, and an HOA may add private restrictions beyond county zoning¹⁷.

How do septic permits work in Nassau County?

Septic permits and inspections in Nassau County go through the Florida Department of Health in Nassau County's Environmental Health section, not Nassau County government³¹⁸. Florida requires the appropriate septic permit for a new system and for covered replacement, repair, modification or abandonment work; a site evaluation determines property conditions and system suitability¹⁹. The soil constraint is substantial: USDA survey data rates 0% of Nassau County soils as free of severe limitations for a conventional septic drain field²⁰. That rating does not decide a particular parcel's result, so obtain the site evaluation before fixing a house location or price. If public sewer later becomes available to a properly functioning septic system, Florida generally requires connection within 365 days after written notice, subject to the stated availability and waiver conditions²¹. For an accessory dwelling, public water and sewer connections are required when available; otherwise, its well and septic must comply with Department of Health rules²².

Can you live in an RV or tiny home on your land in Nassau County?

Nassau County prohibits using an RV or camper for living, sleeping or housekeeping on a residentially zoned lot or any location not approved for that use⁹. Designated RV campsites are the identified locations for an RV or camper stay²³. Storage is different from occupancy: recreational equipment may be stored in a required rear or side yard, and may be elsewhere on residential premises for up to 24 hours while loading or unloading, provided nobody lives in it there⁹. We could not confirm a distinct county occupancy rule for a tiny home. A code-compliant small dwelling still needs a use allowed by the parcel's zoning district, district-specific setbacks and height, and applicable permits¹⁶⁶¹. Nassau County does allow one accessory dwelling on a qualifying single-family parcel, but an RV, mobile home, manufactured home or storage shed cannot serve as that accessory dwelling¹⁷. Ask Planning about a proposed tiny home's classification before buying or ordering it¹⁴.

Building a home in Nassau County: the steps, in order

Ask Planning to confirm the zoning district, allowed residential use, lot size, setbacks and height standards¹⁶⁵⁶.
Check the parcel with Floodplain Management; the special flood-hazard area in unincorporated Nassau County consists of the A and V zones⁷.
Determine whether public utilities are available. If septic is needed, obtain a site evaluation and permit through the Florida Department of Health in Nassau County³¹⁹.
Submit the applicable building-permit materials to the Nassau County Building Department before beginning construction¹¹⁰.
If using the owner-builder exemption, appear personally and sign the application at the county office¹³.
Arrange the Building Department's required plan review and inspections as work progresses¹⁰.
Before relying on a new parcel division, obtain Development Services approval; further division of a parent tract is treated as a subdivision⁸.

What to check before you buy land in Nassau County

Confirm the zoning district and its permitted uses, minimum lot size, frontage, setbacks and height before treating a parcel as buildable¹⁶⁵⁶. Verify that the legal parcel history supports any promised split: a parent tract needs Development Services approval before a building permit, and a further division is a regulated subdivision⁸. Check septic feasibility before choosing the house site because 0% of Nassau County soils are rated free of severe limitations for a conventional drain field²⁰. Ask Floodplain Management whether the land lies in the A or V special flood-hazard zones⁷. We could not confirm the general county driveway-access rule, so ask the Road Department about a proposed entrance on a county-maintained road before closing²⁴. Finally, budget recurring costs: the effective property-tax rate is about 0.7%, the median annual property-tax bill is about $2,558, and the typical annual homeowner-insurance premium is about $2,306²⁵²⁶²⁷.

Watch-outs

Nassau County notes that Chapter 2026-63 (HB 803), effective July 1, 2026, updated Florida building-permit and inspection requirements; confirm the current procedure with the Building Department at (904) 530-6250¹⁰.
Minimum lot size, setbacks and building height depend on the zoning district, so acreage alone does not establish that a parcel is buildable⁵⁶.
A promised land split may require subdivision compliance; Development Services must approve a parent-tract split before a building permit is issued⁸.
