Plumbing plan review
DLI reviews plans for proposed plumbing projects to ensure compliance with the
Minnesota Plumbing Code (Minnesota Rules Chapter 4715). This applies to plans
for modifications to existing plumbing systems as
well as to plumbing plans for new
construction. The review is required for all facilities that serve the public or
that serve a considerable number of persons. Items reviewed include all interior
plumbing, building sewer and water service lines within the property boundary,
and storm water drainage systems. Plans must be designed and signed by either an
engineer licensed in Minnesota, or by a
licensed master plumber. For cities with a population of less than 5,000 people,
a licensed restricted master plumber may also design and sign the plans.
Manufactured structures plan review
DLI regulates manufactured housing (mobile
homes) and prefabricated buildings. It also reviews plans and specifications of
prefabricated buildings for compliance with the State Building Code to include
building, plumbing, mechanical, electrical and energy. The section maintains
installation seal requirements for installers of manufactured homes. It
periodically inspects manufacturers of housing and prefabricated buildings for
compliance with applicable, approved, quality-control procedures and the State
Building Code.
Building plan review
This section provides for the review and evaluation of construction documents
and site inspections to ensure conformance with requirements of the state
building code for buildings paid for by the state or a state agency, public
school district buildings, and buildings which are licensed by other state
agencies such as health care facilities or correctional facilities. The
buildings are reviewed for compliance with the provisions of the Minnesota State
Building Code.

There are two basic types of review the division will perform as a
