"The project went really well and I'm super stoked. Some of my ideas changed as we went through the quote and planning process and Charlie went along with my ideas and gave me feedback. My driveway and yard are exactly how I wanted them. I have an amazing tiered front porch, new side patio and steps, and expanded driveway on both sides. I'm super happy with the work and how everything turned out!"

Custom Home Builders FAQs, answered by experts

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.

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

Handypeople usually don’t hold trade licenses, so they typically aren’t qualified to tackle projects involving installing or making alterations to plumbing or electrical lines. Below are some jobs that a handyperson usually won’t be able to complete:

  • Installing plumbing for a new kitchen or bathroom

  • Replacing plumbing pipes

  • Installing or repairing septic systems

  • Running new electrical wiring

  • Installing a subpanel

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.

It’s typically more cost-effective to move a building along with its accessories than to demolish and rebuild it from scratch. However, that’s only if you can move the accessories without damaging them. However, if you plan to demolish the accessories anyway, it is advisable to do so before the move to save costs.
