Building a modular home will take approximately half of the construction time of conventional construction. Because the modular home is built in the factory concurrently with the grading and construction of the foundation the overall construction schedule is sped up tremendously.
Prior to the building of a home, there is a process to prepare property-specific construction plans. After that, the permitting process takes over and the timeline is based upon their schedule and the number of revisions they require to the plans. The plan preparation and permitting process is a multi-month process that is done before you break ground on your property. Building a site-built home requires these same types of timelines for plans and permits though sometimes our process is faster.
Really though, it is the actual building of the home that is faster.
