County rules: RVs, tiny homes, animals
Zoning: The county zones its unincorporated land. The Johnston County Development Ordinance (Code Ch. 14) applies throughout the county's planning jurisdiction (unincorporated land outside town jurisdictions); rural land is mostly Agricultural-Residential (AR). A replacement UDO was in final review in October-November 2026. Johnston County Code Ch. 14 Land Development Code, § 14-3 Jurisdiction (American Legal)
These are rules for county land outside town limits. Towns have their own. Read on 2026-11-13.
Living in an RV on your landRestricted
The definition bars RVs and camper trailers from permanent occupancy; temporary seasonal occupancy is allowed only in the Resort-Residential (RR) district, whose campgrounds need a site plan. The residential use table (§ 14-89) permits 'RVs/Camper Trailers/Tents' only in RR. No construction-period RV permit was found in Art. I-II.
“these unit are prohibited for the setup and use as permanent occupation. These units may be occupied temporarily within zoned resort-residential district”
§ 14-6 Definitions, "Recreational vehicles"; § 14-76; § 14-89 Table of permitted residential uses, read 2026-11-13
Confirm with Johnston County before you buy land or build.
Tiny house on wheelsRestricted
Tiny houses on wheels are not defined. A wheeled unit built as an RV or camper trailer falls under the RV definition: no permanent occupancy, and temporary use only in the RR district. This classification is inferred, not stated.
“Recreational vehicles and camper trailers are vehicular-type units designed for temporary living for recreation, camping, or travel.”
§ 14-6 Definitions, read 2026-11-13
Confirm with Johnston County before you buy land or build.
Small house on a foundationAllowed
Single-family and modular homes are permitted in AR at up to 1.45 du/ac with public water (lots over 30,000 sq ft) or 1.0 du/ac with a private well (lots over 40,000 sq ft). No minimum dwelling floor area found in Art. I-II.
“Single-family, or individual modular homes”
§ 14-75(b)(1) AR permitted uses; § 14-89 Table, read 2026-11-13
State law: farm buildings outside town limits skip the building code (N.C. Gen. Stat. § 143-138(b4)).
State law: homes on 10+ acres in farm districts (N.C. Gen. Stat. § 160D-903(b)).
State law: building permits (N.C. Gen. Stat. § 160D-1110).
Confirm with Johnston County before you buy land or build.
ChickensNot addressed
AR's permitted-use list (§ 14-75) and the use tables name no backyard poultry use; poultry appears only in the 'Agriculture farm, livestock' definition. § 14-73 says uses not expressly listed are prohibited, so treatment of non-farm hens is a staff call. The Animals chapter (Ch. 4) only defines fowl and regulates animals at large.
§ 14-73; § 14-75; § 14-89/14-90; Ch. 4 Animals, read 2026-11-13
State law: real farms are exempt from county zoning (N.C. Gen. Stat. § 160D-903(a), (a1)).
State law: right to farm (N.C. Gen. Stat. § 106-701(a)).
Confirm with Johnston County before you buy land or build.
Goats and livestockNot addressed
No livestock-keeping standard for non-farm AR lots; livestock appears in the agriculture definitions, in the bona fide farm exemption (§ 14-7), and as farm-type enterprises in AR conditional districts. § 14-73 makes unlisted uses prohibited, so confirm with staff.

Ch. 14 Art. I-II searched, read 2026-11-13

What we couldn't confirm
- A new Johnston County UDO (Proposed Draft Version 4) had meetings 'prior to UDO adoption' on Oct 20, Oct 26 and Nov 2, 2026 (https://www.johnstonnc.gov/planning/content.cfm?pageid=85). I did not confirm whether it has been adopted; if it has, every rule above may have changed.
- Only Ch. 14 Articles I and II and Ch. 4 (Animals) were read on American Legal; Articles III-XII (subdivision, special uses, design standards, administration) were not searched for temporary RV or construction-residence permits.
- The § 14-89 residential use table was read from the county-hosted PDF (https://www.johnstonnc.gov/files/planning/johnstoncounty-nc-2%20Table%20of%20Permitted%20Residential%20Uses.pdf); the RVs/Camper row's column position was read as RR.

Most of Johnston County is out of range. A solar repeater on high ground near the red X would cover the biggest gap. Solar repeater kits
