How to choose a modular home builder

Not every company in prefab housing does the same job. Some sell floor plans or factory-built homes. Some handle land prep, permits, foundation work, delivery, crane set, and finish work. Some only do part of the job.

Ask a simple question early: What exactly do you do, and what do I still need to hire myself? This helps you compare companies fairly.

For example, modular homes are usually built to the IRC code used for site-built homes. Manufactured homes are built to the federal HUD code. ADUs can be modular, manufactured, panelized, or site-built, depending on local rules. If you are still comparing options, see /services/modular-homes/ or /services/adu-builders/.

A modular home price can leave out important parts of the project. The home itself is only one part. You also need to understand site work and finish work.

Ask for a written list of inclusions and exclusions. This should be plain and detailed enough that you can compare one builder to another.

• Home model and base specifications
• Delivery and crane set day
• Foundation type, such as slab, crawlspace, or basement
• Utility connections, driveway, grading, and drainage
• Permits and inspections
• Interior and exterior finish work after the modules are set
• Change orders and how they are priced

If a company gives only a rough verbal number, be careful. Confirm scope, price, and timeline in writing before you hire anyone. You can also review broader planning topics in /guides/ and budgeting topics in /costs/.

A builder may do great work in one area and still be a poor fit for your town or county. Local rules matter. Soil conditions, septic rules, road access, utility requirements, wind or snow loads, and permit processes can all affect the project.

Ask how many projects they have completed in your region. Ask who pulls permits, who coordinates inspections, and who handles problems if the site is not ready when the home arrives.

You should also verify the builder's license and insurance yourself. Ask for the legal business name, license number if required in your state, and proof of insurance.

Many problems happen because homeowners and builders are talking about different parts of the job. A modular home is built in sections, often called modules, in a factory. Then the modules are delivered to the site, set by crane, and finished on the foundation.

Ask the builder to walk you through the full sequence in order. A clear process usually looks something like this:

1. Plan, choose a model, and review your land or lot.
2. Confirm engineering, local code needs, and permit path.
3. Prepare the site, including foundation and utilities.
4. Build the modules in the factory.
5. Deliver and set the home by crane.
6. Finish the home on site, then complete final inspections.

Also ask how financing works for their projects. Some buyers use construction-to-permanent loans. Some manufactured home purchases may use chattel loans, depending on the home, land, and lender rules. The builder should explain what documents they provide, but your lender decides loan terms.

Try to interview at least a few builders using the same questions. That makes it easier to see differences in communication, scope, and experience. You are not just comparing a floor plan. You are comparing project management.

Good questions include: Who is my main contact? How often will I get updates? What site work do you manage? What happens if there is a weather delay or permit issue? How are change orders approved? What warranty applies, and who handles service calls?

Take notes and ask for everything important in writing. If something sounds unclear, ask again in plain language. A reliable builder should be able to explain the job simply. If you want a free way to start comparing companies near you, read /how-it-works/ or request matches at /get-matched/.
