Tips

  • Standard (block) sets require fewer inspections (excavation and final only) than permanent-set homes (excavation, footing, foundation, and final).
  • Confirm the required live snow load rating for your specific site (120 psf or 150 psf) with the Building Department before purchasing — a used home not rated for the site's snow load must have a compliant, freestanding snow roof built to current county code.
  • Any deck, entry, porch, or snow roof attached to the home requires its own separate permit and must be freestanding, not relying on the manufactured home for structural support.
