Tips

  • The manufactured home structure itself is exempt from the county's general Building Safety Code — but the electrical service, and any attachments or affixtures (decks, ramadas, skirting hardware, etc.) you add, are NOT exempt and must be separately permitted and inspected.
  • The county's published '1- and 2-Family Residential and Manufactured Home Permit Time Frames' document groups manufactured homes with standard residential review (30 working days combined) — this is the applicable timeframe for the parts of a manufactured-home project that do require Building Division review.
