First of all, the contractor that you choose needs to be a licensed one. After you discover that they are licensed, find out if there have been any lawsuits or claims filed against that license. They should also have the appropriate levels of insurance so if anyone is injured while they are on your property, you are not liable for their medical bills.

Second of all, you need to talk to each contractor you are considering in person and make sure that you can get along with this person. You both need to be able to get along so you can concentrate on the process of building the home instead of arguing about this or that. This person will be in your life for at least a few months, so hiring someone that you can tolerate is important.

Next, you need to get references from each contractor that you talk to and talk to those references at length and make sure that the contractor does good work. Ask if they have had any mold or water damage issues since their home was constructed or since their remodeling work was finished.

Mold may be the most important issue to look for, since this gets built into new homes more often than most people think due to materials being stored directly on the ground or because they have been rained on.

You should also consider what your contract with this person is going to have in it. You should schedule a date for when the project will start and an approximate date that you want it to have been completed by. If you are expecting a baby or any other major event that will require you to have the home completed, take this into account when hiring your contractor. Find out when they can start on the project and if you do not have any room to be flexible (this is rare), consider hiring someone else.

The contract also needs to contain exactly what materials you want your home to be built from, from the kitchen counter material to the type of finish you want on all the hardware. Be very specific and do not give room for any substitutions, since some contractors will substitute lower grade materials without you noticing if they can get away with it.
