Plan review services

bullet Plumbing plan review
DLI reviews plans for proposed plumbing projects to ensure compliance with the Minnesota Plumbing Code (Minnesota Rules, Chapter 4714). 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.

bullet 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.

bullet 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.

Municipal requests for state plan review of buildings other than public buildings and state licensed facilities
There are two basic types of review the division will perform as a fee-for-service.

  • One is an SBC (State Building Code) plan review. If an SBC review is requested, the division will perform a plan review using State Building Code chapters of Minnesota Rules including 1305, International Building Code; 1306, Special Fire Protection Systems; 1341, Accessibility Code; 1346, Mechanical Code and the State Energy Code.
  • The other is an NFPA 13 fire sprinkler review. If this review is requested, the division will perform a plan review using NFPA 13 and/or other relevant referenced standards.
