Rules another office applies inside Delhi

Delhi does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • The code excludes agricultural buildings except for state inspections required or rulemaking authorized by Minnesota Statutes, sections 103F.141, 326B.36, and 326B.121, subdivision 1, paragraph (c), clause (2).

  “The State Building Code is the standard that applies statewide for the construction, reconstruction, alteration, and repair of buildings and other structures of the type governed by the code, except as provided in Minnesota Statutes, section 326B.121. The State Building Code supersedes the building code of any municipality.”
