Some builders are willing to sell and deliver a pre-built house to a homeowner who will complete the rest of the work. Others arrange the construction and finishing through their own subcontractors. Decide which approach you prefer before talking to builders to make sure you are contracting with a partner who is aligned with your goals.

Transporting the sections from the warehouse to the property costs about $5 per square foot. Delivery charges often relate to the number of sections for the home. Floorplans under about 1,200 square feet may be built as one unit. Larger houses usually come in multiple shipments.

3. Average Cost to Build a Modular Home

In addition to the cost to purchase the modular home, you’ll pay about $52,000 to $167,000 to have it delivered and installed. The wide range accounts for variations in the land and the size of the home. Generally, the company providing the structure prefers to handle all of these tasks, giving you one grand total for the finished home. This estimate from an experienced builder should be highly accurate. Consult the sales contract for procedures concerning delays or damage prior to completion as they may differ between companies.

5. Factors that Impact the Cost of a Modular House

Additional cost factors may vary depending on your local ordinances and options. When planning your budget, be sure to consider:

  • Permits & fees
  • Regional size & design differences
  • Sales tax
  • Custom designs

a. Permits & Fees

The cost of permits and fees ranges from $500 to $5,000. The permits required for preparing the land and installation usually cost the most. Some municipalities may require impact fees for parks, roads or schools. Homeowners may need to obtain permission for:

  • Building
  • Utility Connection
  • Soil Testing
  • Construction of Additional Features

Ask your contractor which permits you need or consult your city's building department.

b. Regional Size & Design Differences

Although prices per square foot tend to be fairly standard nationwide, homeowners may notice regional differences in the size and design of homes available. Companies located in areas with bigger lot sizes may offer modular homes with larger footprints, particularly one-story ranch styles. Home manufacturers that serve urban clientele will most likely have a suite of compact two- and three-story designs that are appropriate for narrow lots.

c. Sales Tax

Homeowners may need to pay sales tax on the modular home components, which average about $5,000 to $10,000. Taxes are usually specific to the state but may also vary by city. The manufacturer of your modular home should be able to answer sales tax questions or contact your local tax office.

d. Custom-Design Prefabricated Home Prices

"If you find custom changes push you over budget, ask your builder to steer you toward a plan that meets your needs. You shouldn't be reworking large portions of the floor plan. Use your dollars for details like bumpouts or window placement changes."Cati O'Keefe, Expert Home Building & Sustainability Contributor.

For a custom modular house, you should plan to pay at least $200,000 to $400,000. Many builders are willing to customize a design beyond finishes like flooring or countertops. Some are able to adapt an existing design or even create a brand-new design. When choosing your modular home builder, ask about the level of design customization offered. If you add a lot of customization, be prepared to exceed the average price per square foot quoted here.

7. FAQs

a. What's the difference in cost between a modular and manufactured home?

Manufactured homes cost around $40 to $50 per square foot compared to $40 to $80 per square foot for modular home construction. The two types may look similar, especially for smaller sizes, but they have one main difference: Manufactured homes are built on a chassis to the national HUD standard. They are considered a vehicle for tax and zoning purposes and can be relocated. In contrast, modular homes are installed on a permanent foundation.

b. How much is a modular duplex?

The price of a modular duplex may not differ significantly from the $40 to $80 per square foot for a single-family home of a similar size, but not all builders offer duplex floorplans. Search for professional contractors who specialize in multi-family construction or ask a manufacturer if they can convert a floorplan from one to two units.

c. How much does it cost for a multi-family prebuilt home?

A two-story prefab home ranges from $84,000 to $168,000. Builders suggest separate floors for multiple generations living in a single house. Homeowners can also consider paying an additional $18,000 to $30,000 to install a walkout basement with a separate entrance.

d. Can you install a modular home on a basement?

Yes. Modular home installers know how to place the modules on top of a basement. When you are doing your research on potential builders ask them for information about including a basement.

e. Are modular homes a good investment?

Yes. According to the Appraisal Institute, modular homes and stick-built homes are appraised and valued using the same metrics. Modular homes have risen in quality in the past few decades, offering many features buyers want, such as:

  • High-end finishes
  • Quality exterior materials
  • 9-foot-plus ceilings
  • Open floor plans
  • Energy efficiency

If you are thinking about buying new construction, going with this type of house may help you save some money and finish the building process more quickly.

f. How long does it take to set up a modular home?

It takes about 4 to 6 weeks to complete the home from the time the sections are delivered to the final walk-through. Builders often quote around 4 to 6 months from the moment they receive a signed contract to a finished installation.
