What are panelized homes and how are they built?

Building a new home can be a dream for many home buyers, but it can also be expensive and takes a while to complete. A panelized home is a lower-cost, faster way to build a new home that meets your wants and needs.

Panelized houses are a type of prefab home, meaning they’re built in panels in a factory and assembled at your location. If you’re considering building a panelized home, here’s what you need to know to make a decision that works for you.

Key takeaways:

• Panelized homes are built in a factory, shipped to your location, and assembled on-site.
• These homes can be less expensive and faster to build than traditional stick-built houses.
• Some benefits of a panelized home include lower total costs, energy efficiency, and flexible designs.

What’s a panelized home?

A panelized home, sometimes called a kit home, is built in a climate-controlled indoor factory, shipped to its destination, and assembled on-site. Panelized homes take less time to build than traditional stick-built homes. The building method also limits the home’s exposure to outdoor elements before it’s completed.

Panelized home builders must follow local and state building code requirements, and the final product is still inspected like a traditional house. However, there is typically more quality control with panelized homes as they’re built in a factory, compared to building a house from the ground up.

While panelized homes aren’t that common, they offer an affordable alternative to building a new construction home. As of 2024, only 2% of homes in the U.S. were modular or panelized.

The building process for panelized home kits

Building a panel home kit has two main stages: the design and production phase, and on-site assembly. The total timeline, from ordering to move-in, can range from 3 – 7 months or longer.

Let’s look at each step in the process.

1. Finding land and securing permits: Before you can begin building, you’ll need to purchase land and secure permits for the home. The timeline can range from 6 – 9 weeks.
2. Preproduction: This phase involves deciding on layout, materials, and design choices. On the short end, it could be a few days, but if there’s a lot of back and forth with the architect, it could be several weeks.
3. Manufacturing: Once a design is confirmed, the panels are constructed in a climate-controlled environment in roughly 2 – 4 months. This step also includes prepping the site and securing financing.
4. Delivery: It can take 1 – 2 weeks, depending on your location, to deliver the panels to the site where the home will be built.
5. Construction: The panels are assembled on the construction site’s foundation and usually completed in about 1 – 3 weeks.
6. Finishing: The home interior is finalized; the final build is inspected, and any touch-ups are completed. This last step can be completed in about 2 weeks, but it can be longer if there are major issues to fix.

Cost of panelized homes

The cost of panelized home kits varies depending on the kit’s specifications, whether you assemble it yourself, and your location. On average, a panelized home kit can cost between $40 – $60 per square foot. If you choose to hire someone to assemble the kit, it can cost about $130 per square foot.

While some home buyers opt to pay cash for their panelized homes, many still finance their purchase. Some lenders offer mortgages for a panelized home, which are similar to manufactured home loans or construction loans. Rocket Mortgage offers conventional loans for qualifying manufactured loans but doesn’t offer construction loans.

Panelized homes vs. modular homes vs. manufactured homes

While you may hear these three home types used interchangeably, they have some key differences. Let’s take a closer look.

Benefits of panelized homes

Panelized homes offer an affordable alternative for a variety of home buyers, including those looking to buy their first home, downsize, or purchase a newly built property.

Here are some additional benefits to consider:

Flexible designs

Panelized homes offer a flexible home design and floor plans. For example, you can choose from various building materials, exterior designs, floor plans, and architectural styles. The panelized home company will likely use a blueprint, allowing you to work with architects and designers to customize your floor plan.

Energy efficient

If you want to build an energy-efficient home, a panelized home is a great option. Panelized homes typically have lower heating and cooling costs. Since the house components are built indoors, they have less exposure to the elements, reducing the risk of warping, mold, mildew, and other issues.

The controlled-building indoor environment keeps materials dry, which can reduce building waste. As a result, they often meet green building certification standards, like the ICC 700 National Green Building Standard, which aims to reduce overall construction material waste.

Cost and convenience

Usually, panelized kits are less expensive than traditional new builds. For example, the average cost per square foot for a panelized home is roughly $40 – $60. On the other hand, a custom-built home can range anywhere from $100 – $500 per square foot.

Since modules are built in a factory, it helps control construction costs, reduce potential delays, and additional material costs. You can choose to assemble the kit yourself or work with the company’s contractors to assemble it on-site for an additional cost, which is roughly $130 per square foot.

Drawbacks of panelized homes

While there are plenty of advantages to panelized homes, they aren’t for everyone.

Here are some of their main drawbacks:

Transportation fees

One cost to anticipate when buying a panelized home is the transportation cost from the factory to the build site. Depending on the transportation company you work with and how far your location is from the factory, the total amount could be costly.

Cost of buying land

Additionally, you still must buy the land for your home, pay for utility connections, and cover other expenses. The cost of land and utility hookups can vary widely depending on the size of your plot and where you live.

Assembly issues

While uncommon, there’s still a risk of problems during the assembly process. You could have issues with damaged panels, either during delivery or assembly. There could also be joint problems or leaks once the assembly has begun, which could cause delays.

The bottom line: Panelized homes can be an affordable alternative to stick-builds

If you’re looking for an affordable alternative to a new construction home, a panelized home can be a great option to consider. With its energy efficiency, customizable design, and shorter build time, buying a panelized home may check all your boxes.

Depending on whether you choose a panelized home or a traditional stick-built home, you can finance your purchase with a conventional loan. If you’ve decided on a home to buy, you can begin the mortgage application process with Rocket Mortgage.
