"I called Choice and reported my problems. They issued a work order and within the hour, I had been notified by S & J Plumbing that they would be here on Thursday. I could not make the time, so I called them and they politely scheduled for the next day. They showed up early, looked over the problems , called in the work to make sure it was covered and they repaired or fixed everything that was needed. They worked on my house like they were working on their own home. After done, they completely cleaned up, reminded me that they guarantee their work, and left. The gentleman who worked on my house was a professional and a credit to his company. I cannot say enough about the quality of work and their concern for everything. I will never forget such a wonderful experience and will not hesitate to recommend Choice Home Warranty. Thank you so much."

"Dennis Duran built our first home about 3 and 1/2 years ago. He was very easy to work with, produced a high quality build, and we are still in it today with no problems at all."

Home Building FAQs, answered by experts

Construction typically takes 3-6 months, including site preparation and assembly.

A custom home is one that you design from the ground up, allowing you to customize everything from the square footage to the interior layout to all of the materials used. A spec home is one that a builder has designed and gotten approvals for. Spec homes may give you some limited options for the layout and materials, but most of the build is pre-set. Custom homes cost more and take longer to build.

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.

Building a house without blueprints is not advised. It will prevent you from obtaining necessary building permits and meeting building codes and is likely to result in shoddy construction and unsafe living conditions. Detailed blueprints ensure that a house is built to exact specifications and is constructed safely and structurally stable.

It is a good idea to check in with your local city and state regulations before committing to building a shipping container home no matter where you live. This concept is pretty new across the country, and many places won’t let you build one.

The International Code Council (ICC) offers guidelines for home builders on the safe use of ISO intermodal shipping containers repurposed as building components, which can be helpful to review when planning or designing a shipping container home.
