One of the questions I get asked the most about building a garage is how high can I build?

This is what the City of Minneapolis handout has to say;

Height, structure or building. The vertical distance from the natural grade measured either at the curb level or at a point ten (10) feet away from the front center of the structure or building, whichever is closer, to the top of the highest point of the structure, or to the top of the highest point of the roof on a flat or shed roof, the deck line on a mansard roof, or the average distance between the eaves and the ridge level for gable, hip and gambrel roofs. 

Accessory structures located in the residence and OR1 Districts. A detached accessory structure, accessory to a principal use located in a residence or OR1 district shall not exceed the height of the principal structure or twelve (12) feet, whichever is less. The maximum height may be increased to sixteen (16) feet or the height of the principal structure, whichever is less, where the primary exterior materials of the accessory structure match the primary exterior materials of the principal structure and the roof pitch matches the primary roof pitch of the principal structure, and provided the wall height shall not exceed ten (10) feet from the floor to the top plate. The zoning administrator shall conduct the administrative review of all applications to increase the maximum height of accessory structures. All findings and decisions of the zoning administrator shall be final, subject to appeal to the board of adjustment, as specified in Chapter 525, Administration and Enforcement

Got it? I didn't think so, allow me to translate in real world terms.

Most detached garages in the City of Minneapolis are built with a gable roof. A gable roof is where you have a peak in the front/back and the water drains off of both sides. If you find the middle of the gable and measure down to the slab that's your height.

Here's how you do it. A 22x22 detached garage with a 4/12 standard roof truss has 8' walls. Now we divide the 22' wide garage by 2 = 11 multiply by the roof pitch 4 = 44". Now we add the heel height of the truss and in this case it's 4" for a total truss and heel height of 48". Now we divide the 48" by 2 which gives us the mid point of 24" and divide that by 12" per 1' = 2'. Don't worry we're almost there. Now we add together the 8' wall height and 2' gable mid point for a total of 10' to the  average distance between ridge and eave.

Still confused? 

  • A 22x22 2 car detached garage with a 4/12 roof pitch = 10' to the mid point.
  • A 22x22 2 car detached garage with 7/12 storage trusses = 11.45 to the mid point.
  • A 22x22 2 car detached garage with 10/12 attic trusses = 12.91 to the mid point.

If you go over the 12' maximum height you can still build the garage of your dreams but you'll have some hoops and additional expense to go through first.
