Prefab and modular homes in the USA: costs explained

1. The four kinds of factory-built home

The Census Bureau uses four terms for houses built partly or fully in a factory.[2]

The split that matters most is between manufactured homes and the rest. Census counts modular, panelized and precut homes as ordinary housing units, alongside site-built houses, and keeps manufactured homes in a separate survey with separate price data.[2]

"Mobile home" is the older, everyday name. HUD's construction standards apply to manufactured homes built after June 15, 1976.[3]

2. Manufactured homes and the HUD code

Manufactured homes are built to one national standard, the Manufactured Home Construction and Safety Standards, usually called the HUD code. Every manufactured home built in the US after June 15, 1976 must be certified by its manufacturer as meeting those standards, and each section carries a certification label, often called the HUD tag.[3] The standards cover the body and frame, thermal protection, plumbing, electrical systems, fire safety and more.[3]

HUD's Office of Manufactured Housing Programs enforces the code, working through private inspection agencies and state governments.[3] It also sets model installation standards for how homes are set up on site.[3]

Because the code is national, HUD's own fact sheet notes that its standards may preempt state and local laws that don't conform to them.[4] In practice, that means the structure of a manufactured home is approved before it leaves the factory, while your local government still controls things like zoning, the site, the foundation and utility connections.

The HUD tag is worth checking when you buy. Lenders and appraisers look for it, and a missing tag can make a home much harder to finance or insure.

3. Modular, panelized and precut homes

Modular homes arrive as finished boxes, often with walls, floors, wiring, plumbing and some finishes already installed. A crane sets the sections on a permanent foundation, and a crew joins them and completes the work on site.[2]

Since they aren't HUD-code homes, your local building department usually reviews them through its normal permit process, much like a site-built house. Ask your county how it handles modular plans and inspections before you order, because practice varies.

Panelized and precut homes leave more of the work to be done on site than modular homes do. Because the parts arrive cut and labeled, they can still shorten framing time and reduce waste.

There is no federal price series for modular, panelized or precut homes. Their costs depend on the manufacturer, the design, the distance from the factory, crane access and the amount of finishing work done on site. The only reliable way to price one is to get a written quote from a manufacturer and a separate quote from a local builder for everything the factory doesn't do.

4. What new manufactured homes cost, by region

The Manufactured Housing Survey, run by the Census Bureau and sponsored by HUD, tracks the average sales price of new manufactured homes every month.[5] Prices come from dealers, who report either the actual sales price or the intended sales price of each sampled home.[5]

In January 2026, the national average was $131,700. Single-section homes averaged $85,400 and double-section homes $160,100.[1]

The West had the highest average at $140,000, followed by the South at $131,600, the Northeast at $129,600 and the Midwest at $124,400.[1] Double-section homes were close in price across regions, between $151,700 in the Midwest and $161,500 in the South.[1]

Prices have been rising. The national average was $120,900 in January 2025,[1] so a year later it was about 9% higher.

For context, the median contract price for a site-built house built by a general contractor on the owner's land was $404,000 in 2025.[6] Neither figure includes land, but the homes differ in size and features, so use the comparison as a rough guide.

5. What the home price doesn't include

The price you see for a manufactured or modular home is rarely the price of a finished place to live. Before you compare it with anything else, add the costs that sit around it:

• Land, if you don't already own it, and its closing costs.
• Site work: clearing, grading, a driveway and drainage.
• The foundation. For federal loan programs, a permanent foundation has to meet HUD's Permanent Foundations Guide for Manufactured Housing.
• Delivery and installation. For modular homes, add crane time and the set crew.
• Utility connections: water or a well, sewer or septic, power and gas.
• Permits and inspections.
• Steps, decks, porches, a garage or carport.
• Finishing work on site, which on a modular home can be substantial.

Our guide to the hidden costs of building a house covers most of these in detail, and the same checklist applies to factory-built homes.

The QuickBuildCost calculator can help here too. Enter the home price as a lump-sum quote, then add your quotes for the foundation, site work and utilities to see the full total.

6. Financing a factory-built home

How you finance a factory-built home depends mostly on its type and whether it sits on land you own.

Modular, panelized and precut homes on a permanent foundation are generally financed like site-built houses, often with a construction loan that converts to a mortgage. Ask your lender how it handles factory payments, because manufacturers often want deposits before delivery.

Manufactured homes have more options, and more variation. The Federal Housing Administration (FHA) has insured manufactured home loans under its Title I program since 1969.[8] Title I can cover the home alone, the lot alone, or the home and lot together.[8] Under the federal rules, Title I loan money can also pay for a permanent foundation, a garage, carport or patio, and any permanent foundation must follow HUD's Permanent Foundations Guide.[7]

A manufactured home that's permanently attached to land you own may also qualify for a standard mortgage, depending on the lender and how the home is titled in your state. Ask lenders early whether they treat the home as real property or personal property, because that affects the loan type, the term and the rate you'll be offered.

Not every lender offers manufactured home loans. HUD keeps a list of approved lenders, and it's worth checking before you commit to a home.

7. Zoning, HOAs and where you can place it

A home that meets the HUD code can still be blocked by local rules about where it can go. Before you buy land or a home:

• Check the zoning for the lot. Some zones allow manufactured homes only in certain districts or in manufactured home communities.
• Read any deed restrictions or HOA covenants. Some ban manufactured homes or set minimum sizes, roof pitches or exterior materials.
• Ask the county about foundation, skirting and setback rules.
• For modular homes, check that a truck and crane can reach the site. Narrow roads, overhead lines and trees can make delivery harder or more expensive.

A phone call to the planning department costs nothing and can save you from buying a lot you can't use the way you planned.

8. How to compare prefab quotes

Factory-built quotes are easy to misread because each company draws the line in a different place. Ask every company to fill in the same list:

Then add the costs that nobody quoted, such as land, site work and utilities, so you're comparing full totals. Our article on the cheapest ways to build a house explains how factory-built homes compare with other ways to save.

9. Which type suits which buyer

A manufactured home makes the most sense when the lowest total price matters more than anything else, and you either own land where zoning allows it or plan to place it in a manufactured home community. It's also the quickest way into a new home of your own, because the house arrives finished.

A modular home suits buyers who want a house that looks and finances like a site-built one but would rather have most of the construction happen indoors, out of the weather. It works best on a lot that a truck and crane can reach, within a reasonable distance of the factory.

Panelized and precut kits suit owner-builders and small builders who want a predictable package of parts but plan to do most of the assembly and finishing themselves or with local trades. Log homes are a common example of the precut approach.

A site-built home is still the most flexible choice for an unusual lot, a custom design, or an area where no factory-built supplier delivers. If you're unsure, price the same floor plan as a modular home and as a site-built home, with identical finishes and the same site work. That comparison will tell you more than any national average.
