What is a prefab home?
A prefabricated home is a type of home built in a factory instead of on the lot where it would be placed. It can be constructed either entirely off-site and delivered in one piece to the place where it will stand permanently. Or, it may be built in sections that will be shipped and assembled by professionals.
There are different types of prefab homes, depending on how the home is constructed and assembled on the property. They include the following:
- Modular homes: These homes are built in modules at a factory and assembled on-site. They are positioned on a permanent foundation and allow the most customization. This makes modular homes the most luxe option among the prefab family.
- Manufactured homes: Also known as “mobile homes,” this type of prefab house can be transported as one piece or in a few large pieces that are put together at the assembly site. The main difference between manufactured and modular homes is a steel-beamed permanent chassis on the mobile home that cannot be removed even when the home is installed at its location.
- Kit homes: Similar to modular homes, kit homes are built in a factory, delivered as pre-cut materials, and put together on-site (similar to how you might purchase inexpensive furniture). These are easy enough for many homeowners to assemble without professional help and are usually the least advanced.
Prefab homes vs. traditional homes
Historically viewed as inferior (and with a stigma they’re still trying to shake off), the prefabricated homes of today are making a comeback as a worthy alternative to traditional (or “stick-built”) homes. Modern prefab homes can be high in quality, quick to construct, and extensively customizable. Also, they offer an excellent solution for those seeking to install an accessory dwelling unit (ADU) next to a primary property for an extra source of income or to increase their property’s resale value. According to a study, an ADU could increase property values by up to 35%.[1]
Are prefab homes cheaper than regular houses?
Short answer: often yes — but “cheaper” doesn’t always mean “everything included.”
When you compare a prefab home and a traditionally built (stick-built) house purely on factory component cost, prefabs tend to win. For example, one industry guide cites finished modular homes at roughly $80 to $160 per square foot, compared with typical site-built averages that can run much higher.[2] Constructing a new stick-built house can average $150 per square foot.[3]
That said, many prefab listings show only the factory-built portion of the build. The base price usually excludes land, foundation, delivery, utilities, permits and finishing. According to one walkthrough of “hidden costs,” a home that advertises $90 K factory price could end up costing $150-200 K once everything is added.
| Cost Category | Prefab Home | Typical Site-Built Home |
| Factory module or shell | Included in prefab quote | Assembly on-site |
| Land purchase | Required for most prefab builds | Required in nearly all cases |
| Site preparation & foundation | Often extra (grading, leveling, foundation) | Part of build cost |
| Utility hookups (water, sewer, electricity) | Often extra | Included |
| Delivery/on-site assembly | Extra | Included |
| Finishing, landscaping, exterior features | Extra | Included |
| Financing differences and resale impact | Can vary widely | More established paths |
Because of all these variables, a prefab home could cost 10-25% less than a comparable traditional home, but the gap varies dramatically by region, how much customization you want, land/site conditions and your chosen builder.
Bottom line: If your goal is to save money, a prefab home is promising — but only if you budget realistically for everything beyond the factory pieces. Before you commit, get a fully itemized quote, include land/site costs, and compare to similarly sized existing homes in your market.
Weighing the pros and cons of prefab homes
Prefab homes can be a wonderful alternative to traditional homes, but there are also some downsides to be aware of. Let’s take a quick look at prefabricated homes' benefits and drawbacks to see whether it’s the right choice for you.
Pros of prefabricated homes
Energy efficiency
Many modern prefab homes are designed with energy efficiency in mind. Prefab manufacturers opt for innovative techniques and sustainable materials, and it’s easy to find a company that produces ENERGY STAR-certified homes. Thanks to their tight seams and quality windows, prefab homes these days are often well-insulated and can help keep your utility costs down.
Sustainability
The construction process discussed above also impacts the eco-friendliness of prefab houses. The fact that all components are pre-built and manufactured at a factory means that unused materials can be recycled, reducing waste and lowering the carbon footprint of the home. Improved insulation can also allow you to depend less on your AC in the summer and heating in winter, reducing the negative impact on the natural environment.
High quality
While a traditional home is usually only inspected once upon completion, prefabricated home manufacturers have fierce quality control standards and ensure that all components are examined multiple times throughout the process. Manufacturing a home at a factory often allows for higher precision, the tighter joining of pieces, and avoiding weather conditions that may impact the final result.
Fast construction time
In traditional home construction, the start of one subcontractor’s work often depends on the timely completion of another subcontractor’s work — for example, an electrician can’t begin their job until the frame is finished. This dependency, along with weather delays and scheduling conflicts, can slow down the building process. In contrast, the ready-to-go nature of prefab components sidesteps this issue, allowing labor to be planned and carried out more efficiently.
Affordability
The cost is one of the major reasons why prospective homeowners turn their attention to prefab homes. Due to the reduced waste, streamlined production processes, significant automation, and faster build time compared to stick-built homes, prefabricated houses usually tout a lower price tag. Generally, they tend to be 10%-25% cheaper than traditional homes.[4]
Cons of prefabricated homes
Land and site preparation
When readying a prefabricated home for occupancy, you’ll need land to assemble it on. Aside from the cost of the land, you would also have to factor in the cost of site preparations and connecting utilities. Depending on the home’s location and the specifics of the site you’re building on, it could be challenging to set up water or arrange electrical connections. All this might offset potential savings from choosing a prefab, especially if compared to buying an existing home.
Zoning laws
Rules and regulations are important to consider when trying to decide whether you want to build a prefab home. Some municipalities and local governments might have restrictions on the placement of manufactured or kit homes. Even if it is allowed, your prefabricated home would have to meet established building codes.
Financing limitations
Depending on the type of prefab you’re building, it may be tricky to secure financing for your future home. Generally, modular homes can be financed through a traditional mortgage, and the cost of construction can be paid through a construction loan. But things get more difficult if you’re looking to obtain financing for a manufactured home. There are some specialized loans, such as FHA Title I and Title II loans or chattel mortgages, but not all lenders offer them.
Longer move-in time
Even though prefabs take a shorter time to construct than stick-built ones, if you want to move quickly, it’s better to purchase an existing home in most cases. While prefabs can be efficiently completed within a few months, buying a house that’s already constructed will almost always be a faster process.
Potential difficulty selling
Depending on the type of prefab you own, you might encounter some difficulty getting buyers interested. In the past, manufactured homes were almost always of a poorer quality and assembly than stick-built dwellings, which hurt their public perception. As a result, they often depreciate while traditional homes build value over time, so potential purchasers may be turned off when they see that your home is prefabricated. While the reaction may be unwarranted, it’s the reality of the market and a risk you’ll need to account for.
Tips for buying a prefab home
Buying a prefab home may look simpler than a traditional build — but it comes with its own unique checklist. Here are six key steps to help you avoid surprises and make a smart purchase.
Step 1: Clarify your goal and budget.
- Decide what type of prefab you’re aiming for (modular vs manufactured vs kit vs panelized) and how much customization you want.
- Build a realistic budget: Include land, site prep, foundation, delivery, permits and finishing, not just the “home” price.
- Check timeline expectations: While factory build goes fast, site prep and delivery still take time (sometimes months).
Step 2: Choose the right prefab type and builder.
- Evaluate several manufacturers — look at reviews, factory warranties, build quality and factory inspection history.
- Ask for detailed module specs (R-value insulation, structural code, finishes) and check whether your local zoning, insurance, and financing environment supports that type.
- Compare price transparency: Make sure you get a quote for “factory shell” vs “everything included.”
Step 3: Secure land + confirm site feasibility.
- Do a zoning, setbacks and permitted-uses check on your lot: some municipalities restrict manufactured homes or certain prefab types.
- Confirm utility access (water, sewer, power, internet) and estimate cost of hook-ups or well/septic if needed. Hidden costs can be significant.
- Perform a site survey/soil test so you understand foundation type and site preparation needs.
Step 4: Line up financing early.
- Understand financing differences: Modular homes built on permanent foundations often qualify for conventional mortgages; manufactured homes may require specialized loans or be classified as personal property.
- Ask lenders about construction-to-permanent loans (for prefab build), chattel mortgages (for personal-property homes), and whether your chosen structure qualifies under Fannie/Freddie, FHA or VA programs.
- Build in contingency for cost overruns or delays.
Step 5: Manage delivery, assembly and finishing.
- Check the delivery logistics: How far is the factory from your site? Will large transport or crane costs apply?
- Hire a local general contractor (or prefab installer) who understands prefab homes and works with your manufacturer.
- Monitor onsite finishing: Make sure the final home meets local code inspections, that the factory modules were transported without damage and that warranties are enforced.
- Ask for documentation: factory inspection reports, transportation logs, final local code approval.
Step 6: Plan your resale or exit strategy.
- Ask: How do homes of this type perform in your market? Will resale value track with stick-built homes? Some types (e.g., manufactured) may depreciate or have limited financing resale.
- Consider future flexibility: Will your land allow expansion, conversion, or resale easily? How does the builder’s warranty transfer to new owners?
- Keep detailed records (build specs, warranty, manufacturer info) to support future buyer confidence.
Common mistakes to avoid:
- Signing a “factory‐only” contract without budgeting for site and finishing costs.
- Assuming land purchase and site prep will be minimal — many buyers underestimate by tens of thousands.
- Choosing the cheapest builder without checking local permits, building code compatibility or warranty support.
- Overlooking resale or financing limitations — check with your real estate agent early.
- Rushing the timeline: Even “quick” prefab builds still depend on land, delivery, utilities and local inspections.
By following a structured process and asking the right questions, you’ll position your prefab home purchase to be smoother, better-budgeted and aligned with your long-term goals.
