Single-family dwellings of woodframe construction not more than two stories and basement in height.
Multiple dwellings containing no more than four dwelling units of woodframe construction not more than two stories and basement in height. However, this

complexes where the total exceeds four units on any lawfully divided lot.
Garages or other structures appurtenant to buildings described under subdivision (a), of woodframe construction not more than two stories and basement in
Agricultural and ranch buildings of woodframe construction, unless the building official having jurisdiction deems that an undue risk to the public health,

building code duly adopted by the local jurisdiction or the state, the building official having jurisdiction shall require the preparation of plans, drawings,
specifications, or calculations for that portion by, or under the responsible control of, a licensed architect or registered engineer. The documents for that portion
shall bear the stamp and signature of the licensee who is responsible for their preparation. Substantial compliance for purposes of this section is not intended to
restrict the ability of the building officials to approve plans pursuant to existing law and is only intended to clarify the intent of Chapter 405 of the Statutes of
