North Carolina County and Code Starting Points

Guilford County Manufactured Home Starting Points

In the parts of Guilford County the county governs, a manufactured home is allowed by right in only one district: AG, Agricultural — about 41 in 100 acres of the land the county zones. In most other residential districts it takes a rezoning, and the rezoning needs ten neighboring lots or 2.75 acres of land. Every home also needs a masonry foundation or masonry curtain wall all the way around: vinyl skirting does not meet the rule. And about 87 in 100 Guilford addresses are under a town's rules instead.

Common Questions

Mobile homes in Guilford County, answered from the county's own sources.

Can I put a mobile home on my land in Guilford County?

Which zoning districts in Guilford County allow a mobile home?

Allowed by right in one district of twenty: AG. A site-built house is allowed by right in every residential district. A manufactured home is allowed by right only in AG, Agricultural — about 41% of the land the county zones. Source: Guilford County Unified Development Ordinance, reviewed 2026-09-10.

What permits does a mobile home need in Guilford County?

The overlay needs ten neighboring lots or 2.75 acres. Outside AG, the only way to place a manufactured home on a single-family lot is a rezoning to the Manufactured Housing overlay. A rezoning is a legislative decision, not a staff permit. Source: Guilford County Unified Development Ordinance, reviewed 2026-09-10.

Does Guilford County set rules on the home itself — width, skirting or roof?

Every home needs a masonry foundation or masonry curtain wall. The ordinance sorts homes into classes. The lowest allowed class, B, still requires a continuous masonry foundation or masonry curtain wall around the whole home, with openings only for vents and access. Source: Guilford County Unified Development Ordinance, reviewed 2026-09-10.

Can I put more than one mobile home on the land in Guilford County?

A second home on the lot has a class rule. When a mobile home is the second, accessory home on a lot, the main home must be a Class AA double-wide or a site-built house. Source: Guilford County Unified Development Ordinance, reviewed 2026-09-10.

Official-source-backed starting points and questions to verify.

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.

Where a home is allowed

Allowed by right in one district of twenty: AG.

A site-built house is allowed by right in every residential district. A manufactured home is allowed by right only in AG, Agricultural — about 41% of the land the county zones.

RS-40, RS-30, RM-18 and RM-26: only after a rezoning to the Manufactured Housing overlay.
RS-20, RS-3, RS-5, RS-7 and RM-8, and every business and industrial district: not allowed.
Land already granted the overlay shows on the county's zoning map with an -MH ending, such as RS-40-MH. That is about 4% of the county-zoned land.
AG and RS-40 have the same lot-size and setback rules, but only AG allows the home. The barrier is the district, not the lot.
A manufactured home park needs a special use permit, only in RM-8, RM-18 and RM-26.

The rezoning

The overlay needs ten neighboring lots or 2.75 acres.

Outside AG, the only way to place a manufactured home on a single-family lot is a rezoning to the Manufactured Housing overlay. A rezoning is a legislative decision, not a staff permit.

To apply, the land must be at least ten existing lots side by side covering 90,000 sq ft, or
at least 120,000 sq ft (2.75 acres) of land not yet divided into lots.
An owner with one ordinary lot cannot apply.
The ordinance's text says the overlay can go in any residential district. Its use table allows it in only four. WHICH ONE THE COUNTY FOLLOWS IS UNKNOWN. Ask before counting on it.

What the home must be

Every home needs a masonry foundation or masonry curtain wall.

The ordinance sorts homes into classes. The lowest allowed class, B, still requires a continuous masonry foundation or masonry curtain wall around the whole home, with openings only for vents and access.

Vinyl skirting does not meet this rule. The ordinance allows vinyl for the home's siding, not for the foundation wall.
Class B: towing hitch, wheels and axles removed; the masonry wall; siding of vinyl, aluminum, wood, pressboard, stucco, brick or stone.
Class A adds: at least 700 sq ft of heated space, length no more than 4 times the width, a roof pitch of at least 3.5 in 12, 6-inch eaves, and code-built steps and porches.
Class AA adds a 16-ft minimum width and a few more rules. The width rule applies only to Class AA.
A home that meets none of the classes (Class C) is not allowed anywhere, except as certified migrant farm-labor housing.

More than one home on the land

A second home on the lot has a class rule.

When a mobile home is the second, accessory home on a lot, the main home must be a Class AA double-wide or a site-built house.

A single-wide Class A or B home may never be the second home beside another Class A or B home.
In the Scenic Corridor Overlay, only a Class AA home is allowed.

Lot size and setbacks

In AG, the road decides the front setback.

The front setback in AG depends on the kind of road the lot faces. Ask the county which class your road is.

Local or collector road: 40 ft. Minor thoroughfare: 45 ft. Major thoroughfare: 50 ft.
Side: 15 ft. Rear: 30 ft.
Lot at least 40,000 sq ft, 150 ft wide, with 50 ft of road frontage.
The home and other buildings may cover no more than 30% of the lot.
A flag lot has its own limits: no more than 3 acres without public sewer, and a pole at least 25 ft wide and no longer than 300 ft.

Flood

In a flood zone, masonry needs flood openings too.

Guilford's masonry rule and its flood rules both apply, so a home in a flood zone needs both.

Masonry underpinning counts as an enclosure in a flood zone and needs flood openings.
In flood zones A, AE, AH, AO and A99, a home whose chassis sits more than 36 inches above the ground needs an engineered foundation certification.
Near Piedmont Triad International Airport, the airport overlay allows a single-family home only on a lot of at least 40,000 sq ft.

Trees

No county tree rule for one home on one lot.

Guilford's tree rules apply to required landscaping on business and multi-family projects, not to a single home.

No county clearing permit, tree survey or replanting rule for one home.
State erosion-control rules still apply to grading.

Who writes the rules for your address

About 87 in 100 Guilford County addresses are under a town's rules.

The county's rules cover about 40,000 of the county's 299,000 addresses — land outside every town and every town's ETJ.

Greensboro and High Point hold most of the rest. Summerfield, Gibsonville, Oak Ridge, Stokesdale, Jamestown and Pleasant Garden are among the other towns.
Inside a town or its ETJ, the town's rules decide. This page does not cover any town's rules.

Local Prerequisites To Verify

Environmental health, utilities, zoning, and access may shape the sequence.

Septic approval or existing-system review

County sources often require septic approval, construction authorization, or existing-system authorization before or alongside manufactured-home permitting.

Septic

Well or water availability

County sources may require well, public water, or water-sewer tap documentation before a permit can move forward.

Well Plumbing

Water/sewer availability

Some county sources ask for sewer approval, tap receipts, or public water documentation when applicable.

Plumbing Septic Well

Utility service availability

Some county sources connect power release or final readiness to completed trade inspections or utility-provider steps.

Electrical HVAC Propane / Gas

Zoning or land-use review

County sources may require zoning, municipal zoning, watershed, floodplain, or land-use review before manufactured-home placement.

Engineering

Driveway or access

Driveway, access, or delivery-route questions belong in the library only where county or source-backed process notes make them relevant.

Driveway Improvement Grading and Site Preparation Transport and Setup

Inspection-Related Scopes

Limited to source-backed manufactured-home scopes.

Grading and Site Preparation

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.

Transport and Setup

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

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

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.

HVAC

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.

Propane / Gas

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.

Decks / Stairs / Landings / Handicap Ramps

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.

Masonry / Block / Foundation

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.

Vinyl Skirting

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.

Trim-Out / Carpentry

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

Bring better questions to the right local office.

Is the parcel inside a town's limits or its ETJ, or under Guilford County's rules?

What is the parcel's zoning district? Is it AG, or does it already carry an -MH overlay?

If it is not AG, can the overlay be applied for in this district, and what does the rezoning take?

Which road class does the lot face — local or collector, minor thoroughfare, or major thoroughfare?

Which class of home — AA, A or B — will the county treat this home as?

Is any part of the parcel in a flood zone, a watershed critical area, the airport overlay or the scenic corridor overlay?

Will the parcel need a septic permit and a well permit?

Dealer Quote Responsibility Questions

Ask who owns each step before the project depends on it.

Has anyone confirmed the parcel is zoned AG or already carries an -MH overlay?

Is a masonry foundation or masonry curtain wall in the price? Vinyl skirting does not meet Guilford's rule.

Which class — AA, A or B — does this home meet, and has anyone checked it against the lot's rules?

If this is a second home on the lot, does the main home meet the class rule?

Is any part of the parcel in a flood zone, and are flood openings planned in the masonry?

What To Gather

Better details make county and provider questions clearer.

Property address and parcel identification number.

The zoning district, and whether it ends in -MH.

Whether the parcel is inside a town's limits or ETJ.

The home's width, length, heated square feet and roof pitch.

Any homes already on the land.

The FEMA flood zone for the parcel.

Source notes

The use table, overlay rules, home classes, setbacks, park, flood and tree rules are read from the Guilford County Unified Development Ordinance (adopted 2020-11-19, amended 2022-01-20), read in full 2026-09-07 and re-fetched unchanged 2026-09-10.

The district shares and the -MH overlay areas are measured from the county's zoning map layer, which the ordinance names as its official zoning map, 2026-09-07.

The share of addresses inside a town or ETJ is measured from the state address file and the state's town-limit and ETJ map, 2026-09-07.

The ordinance's text and its use table disagree on which districts can take the overlay. Which one the county follows is UNKNOWN until it answers.

Whether the county publishes each road's class for the AG front setback was not established. Ask the county.

No written answer from the county planning office is on file for this page.

Town ordinances were not read. Everything on this page applies outside town limits and ETJs only.

This page carries the offices, not staff names.

No zoning determination, permit outcome, flood determination, septic approval, or inspection result is implied.
