We were really impressed with Dave Kinsella's design concepts and the workmanship was high quality even though we were on a tight budget. Dave comes from a big family so he understands money and time constraints plus he wants his projects to look as aesthetically pleasing to his clients as possible. We would definitely hire Dave again."

Custom Home Builders questions, answered by experts

Yes, home builders need to be licensed in every state and municipality in the country. The specific license required varies based on the location and the work, but most states require that the builder hold a general contractor’s license at minimum. Some states and cities also require that plumbing, electrical, roofing, and sewage system construction require individual licenses, in which case the builder may subcontract the work. You can use Angi’s contractor licensing tool to confirm that the builder you’re considering holds all the proper licenses.

In most cases, you should get an architect before you hire a builder. An architect will be the one to draw up formal plans for your project, including guidelines and even material lists for your builder to follow during construction. Many architects can even help you find builders, choose one for your project, and negotiate prices. Some are also willing to act as project managers throughout the process, working closely with a builder from start to finish.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.

Yes, a home builder should have a builder’s license and insurance. States have different requirements for builder’s licensing and certifications. Be sure to check our state licensing tool to review your local home builder licensing guidelines.

As you browse our pro listings, take note of the “Angi Certified” badge. Angi Certified businesses meet our standards for certification, which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Framing is often the most expensive phase of building a house because it’s time-consuming and requires a lot of materials. It costs between $20,000 and $50,000 on average, depending on materials and labor costs. Before construction begins, it’s possible that purchasing land is the priciest step in the process. Some plots of land sell for $3,000, while others cost upwards of $150,000.
