"service provider sent by American Home Shield was excellent. The only issue I have with home warranty services is that they do not send their repair companies out on the week-end, even in an emergency. The customer service personnel is less than enthusiastic or helpful."

Custom Home Builders FAQs, answered by experts

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.

The most significant expense when building a barndominium is constructing the metal shell, which includes the roof, doors, and windows. Additional exterior components impacting the overall cost include metal siding and the concrete foundation.

Yes, a home builder or contractor should have the proper licensing and insurance. Licensing requirements vary by state and municipality, but most states mandate that a builder holds at least a general contractor’s license. For specialized work such as plumbing, electrical, roofing, or sewage systems, individual licenses may be required, in which case the builder may subcontract the work. You can use Angi’s state licensing tool to review your local guidelines and confirm a builder's credentials. As you browse professionals, you can also look for the “Angi Certified” badge. This indicates the business meets our certification standards, which include passing a criminal background check, holding applicable state and local licenses, and maintaining an average rating of 3.0 or better.

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

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.
