Design Professional Requirements

What is a design professional?

A design professional is licensed or certified by the Minnesota Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience and Interior Design (AELSLAGID) to practice their respective disciplines.  Plans must be prepared and certified by a design professional unless specifically exempted in state licensing rules.  The building code authorizes the building official to require plans to be prepared by a design professional for an exempt building if special conditions exist.

A permit application must include plans and specifications for the project with the name and address of who prepared the plans.  Plans must provide information that clearly shows that the project design complies with the building code and other laws and ordinances that apply to the project.  The plan preparer must certify that reasonable care has been given to compliance with applicable laws, ordinances, and building codes.

The requirement for quality and completeness of plans and associated documents is the same whether prepared by a design professional or not.

Construction Services Pre-Review Meetings

Construction Services’ preliminary review meetings are a free service provided to architects, engineers, owners, builders and others in the development community as an opportunity to introduce projects to Construction Services, Zoning and other city staff.  These meetings are a chance for questions and clarifications regarding code requirements and presentation of reasoning for alternate methods or modifications and for requests for code interpretations.  If you need a meeting that is primarily focused on stormwater management requirements, utilities or streets, contact Engineering at (218) 730-5200.  If you need a meeting primarily focused on UDC (zoning) issues or you need to schedule a Planning pre-application meeting, contact Planning at (218) 730-5580.

Designers can meet with plan review staff to review big-picture issues and address areas of specific concern at an early stage.  Preliminary review meetings are not a replacement for a detailed review of final plans, but if conducted in advance of completing the construction documents, can reduce time required to address major issues discovered during final plan review.

Preliminary review meetings are available on Wednesdays.  To schedule a meeting, complete the form in the link below and email it and items listed on the form to Construction Services:

The deadline to request a meeting is the Friday of the previous week.  When the complete request form and other information is received, you will be offered available meeting times.
