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.
