North Carolina County and Code Starting Points
Johnston County publishes separate official pages for the building-permit sequence, permit requirements, mobile-home applications, zoning questions, and manufactured-home footing, underside, and final inspections.
Manufactured Home Placement Questions
This page organizes source-backed topics for Johnston County. County and local AHJ sources are local process layers for permits, forms, inspections, zoning, environmental health, utility coordination, and office sequencing. They do not replace the NC Installation Manual, county staff, licensed professionals, utility providers, manufacturer instructions, or the authority with jurisdiction over the work.

Source Hierarchy
Use the NC Installation Manual as the primary statewide installation source. Use NC OSFM as the state manufactured-homes program authority and document hub. Use Johnston County and local AHJ sources for permit steps, forms, inspection procedures, zoning, environmental health, utility coordination, and office sequencing. Confirm project-specific questions with the county, AHJ, utility company, manufacturer instructions, licensed professionals, and the responsible provider.

Official NC OSFM manufactured building division page for manufactured and modular housing resources.
local process source
County and local AHJ sources explain local process layers; they do not replace statewide installation guidance or project-specific authority.
Johnston County Local Process Guide
These sections organize the public source links already reviewed for this page. Where a source does not answer a project-specific question, the item is framed as something to ask the county, AHJ, utility company, licensed professional, dealer, setup contractor, or responsible provider.
Local facts 1-2
Johnston County separates planning, utility or environmental-health, site-plan, and inspections work.
Local facts 3-4
The county inspection guide identifies when work must remain visible.
Local facts 5-6
The county guide connects concealment and final completion to later approvals.
County Links and Source Notes
Treat these county links as local process sources. For installation-specific requirements, confirm the NC Installation Manual, manufacturer instructions, licensed professionals, and the AHJ before relying on a county page alone.

Local Prerequisites To Verify
County sources often require septic approval, construction authorization, or existing-system authorization before or alongside manufactured-home permitting.
County sources may require well, public water, or water-sewer tap documentation before a permit can move forward.
Some county sources ask for sewer approval, tap receipts, or public water documentation when applicable.
Some county sources connect power release or final readiness to completed trade inspections or utility-provider steps.
County sources may require zoning, municipal zoning, watershed, floodplain, or land-use review before manufactured-home placement.
Driveway, access, or delivery-route questions belong in the library only where county or source-backed process notes make them relevant.
Inspection-Related Scopes
Use only where source-backed county or state guidance ties grading to pad, drainage, foundation readiness, access, footers, or setup readiness.
Several county sources reference site grading, drainage, footings, setup readiness, or documents needed before power or final signoff.
Core manufactured-home installation scope for delivery, setup, pier/blocking, anchoring, tie-downs, setup contractor information, and inspection readiness.
The NC Installation Manual is the primary statewide installation source; county manufactured-home process pages may add local setup contractor, permit, and inspection steps.
Electrical service, site-installed electrical work, utility handoffs, and inspection readiness when source-backed.
County sources commonly separate electrical permits or inspections for mobile/manufactured-home setup.
Plumbing connections, water and waste lines, pressure or water tests, and final readiness where source-backed.
County sources commonly separate plumbing permits or inspections for mobile/manufactured-home setup.
Mechanical systems, heat pump or air-conditioning work, ducting, and final readiness where source-backed.
County sources commonly reference mechanical permits or inspections for mobile/manufactured-home setup.
Use only when official guidance mentions gas service, gas appliance connections, LP systems, fuel-gas inspection, pressure testing, shutoffs, or installation-manual requirements.
Onslow County explicitly groups gas fuel work with prescriptive code and NC manufactured-home regulations for manufactured-home permits.
Egress, steps, landings, handrails, ramps, deck thresholds, and final access readiness where source-backed.
County manufactured-home guides may reference stoops, steps, landings, handrails, and deck-size thresholds.
Footings, piers, blocking, masonry skirting/foundation presentation, soil bearing, anchorage, and foundation readiness where source-backed.
County sources reference footings, piers, blocking, anchorage, soil bearing, tie-downs, or foundation-related items in inspection processes.
Skirting or underpinning only where source-backed guidance connects it to inspection timing, access, ventilation, appearance, or placement requirements.
County manufactured-home inspection documents may reference skirting timing, access panels, or underpinning requirements.
Use only where official guidance touches final trim-out, marriage line completion, close-up, access panels, finish details, weatherproofing, or readiness for final inspection.
Onslow County references marriage wall inspection for multi-wide homes and close-up type items within manufactured-home setup inspections.
Questions To Ask The County
Which Planning office controls zoning for the parcel, especially inside a town or extraterritorial jurisdiction?
What well, septic, public-water, or sewer approvals must accompany the building-permit application?
Which mobile-home and residential trade applications apply to the setup scope?
What must be complete and exposed for footing and underside inspections?
Which final-inspection and Certificate of Occupancy approvals precede permanent power or water under the current local process?
Johnston County uses mobile-home language on several official permit and inspection pages; the page preserves that source terminology where needed.
Parcel-specific zoning, setbacks, floodplain, septic, utility, and inspection results must be confirmed with the responsible office.
The page omits fees and timing claims that could change.
Helpful Next Steps
Use these pages to organize the next question by stage, responsibility, utility path, setup readiness, or private project summary. They do not replace county, utility, AHJ, or professional confirmation.
Prepare for footing, underside, marriage-line, trade, and final checkpoints.
Organize jurisdiction, zoning, environmental health, permit, trade, and utility-release questions.
Collect property, placement, access, utility, and environmental-health details before submittal.
Next Step
Use the planner, roadmap, provider type library, and project request path to connect local process questions back to the work you are trying to sort.
Land question first?
Review zoning, septic or sewer, water, access, utilities, site prep, dealer quote, and setup questions before assuming the land works.
Preparing land for delivery?
Organize clearing, grading, driveway access, septic or sewer, water, utilities, setup workspace, and dealer quote questions.
Delivery coming into focus?
Sort land-use, septic or sewer, water, access, site prep, utilities, dealer responsibility, setup, and local process questions.
Utility questions unclear?
Organize septic or sewer, well or water, electric, plumbing, HVAC, propane/gas, dealer scope, and local process questions.
Setup or final questions?
Organize setup contractor, foundation, utilities, decks, stairs, skirting, trim-out, inspection, and dealer-scope questions.
Checking NC guidance?
Understand how the NC Installation Manual, NC OSFM, county/local AHJs, manufacturer instructions, and licensed professionals fit together.
Not sure where to start?
Find your current stage, likely next steps, provider types, documents to gather, and delay risks.
Trying to see the whole path?
Review the stage-by-stage project sequence from planning and land through setup and move-in.
Reviewing a quote?
Separate what may be included, excluded, estimated, or assigned to another party before you sign.
Trying to understand who may help?
Learn the provider categories that may be involved without treating the guide as a public directory.
Need to explain your project?
Share the stage, ZIP, county, and question you are trying to organize for private review.
