Yes, there is a wide range of builder types and categories. AND, to make it even more confusing, a builder can float between a few different categories. To make it simple though, we like to break builders into three different categories:
Production Builders: These are your volume based builders, which can build 50+ homes a year. They typically build in specific communities (not necessary off-site) and have a variety of home plans to choose from.
Semi-custom Builders: Also known as Semi-production, these types of builders tend to offer a little more customization when it comes to plans and selections. They have their process and model, but might give you the leeway to change a plan or bring an outside selection in. They typically build anywhere from 20-75 homes per year.
Custom Builders: There's no restriction with most custom builders. In fact, we like to call these builders the "start from scratch option." They craft your vision by offering guidance and direction. Many custom builders have plans for inspiration (or as a starting point) while others have you sit down with an architect to design your home right in front of your eyes. Typically, custom homes come with a higher price and a little more ambiguity because the parameters aren't identified on day one.
Keep in mind that many builders don't fit perfectly into any category so interview each builder based on what you're looking for to see who might be the best fit.
