What Does a Modular Home Budget Look Like?
When building a new prefab house and analyzing the project budget, we typically see modular home costs break down into 4 sections.
Modular Home Budget Categories
Design + Engineering + Permitting Cost
Modular home
Typically, companies communicate and bill this price as one line item. In general, this includes:
Framing
Internal systems (plumbing, HVAC, electric, sprinkler, fire sprinklers, etc)
Insulation
Windows, doors
Finishing materials
Painting
Transportation & Set
Crane
Transportation Company
Site Work
Decks
Foundation
Driveway
Seismic connections
Crossover connections (this covers connecting utilities and systems between modules and to the power, water, and sewage system)
Siding & Painting (this is typically completed on-site for multi-modular projects and off-site for single modular projects)
Solar
Garage construction [which is most frequently site built]
