Summary
Hooking up a mobile home's basic water and sewer riser connections in unincorporated Polk County doesn't need its own plumbing permit, but any plumbing work beyond that basic connection does. Polk County Code Sec. 5-170 requires the owner-occupant or a licensed, registered plumbing contractor to get a permit before starting that extra work.
Sec. 5-170. - Plumbing. Plumbing connections or piping other than the basic connection from the lawfully installed potable water supply connections to the mobile home and the connection from the lawfully installed sewer riser to the mobile home are outside the scope of service work and shall be performed either by a person who is both owner and occupant of that mobile home or by a licensed plumbing contractor properly registered with the building and zoning codes department. All work shall be done in accordance with the county plumbing code, and no work shall be done until a permit is obtained.

Full Breakdown
Polk County's Mobile Home Set-Up Code (Article V of Chapter 5, Ord. No. 74-9) requires a set-up permit before any mobile home is placed as a dwelling, per Sec. 5-150. Section 5-170 carves out plumbing specifically: connections or piping beyond the basic hookup from the lawfully installed potable water supply and sewer riser to the home are outside routine "service work," and can be performed only by a person who is both owner and occupant of the mobile home, or by a licensed plumbing contractor registered with the building and zoning codes department, done in accordance with the county plumbing code and only after a permit is obtained.
Section 5-152(c) doubles the applicable permit fee whenever set-up work, including this plumbing work, is started before a permit is obtained and only later gets permitted. Contractors performing this service work must first register annually under Sec. 5-156, posting a $5,000 bond and proof of liability insurance and workers' compensation coverage. Section 5-157 lets the building official demand corrections within 10 days of notice for nonconforming work, and the building board of review can suspend or revoke a contractor's registration for continued violations after 10 days' written notice.
Violations & Fines
Starting mobile home plumbing work before a permit is issued doubles the required permit fee under Sec. 5-152(c). Performing this work without being the owner-occupant or a properly registered, licensed plumbing contractor violates Sec. 5-170, and repeated nonconforming work can lead the building official to withhold further permits under Sec. 5-157(a) or trigger suspension of the contractor's registration by the building board of review.
