Apartment Window Replacement Permit — Commercial Code and City License
Replacing windows in a house is a simple permit. In a twelve-unit building, the city may want a commercial permit, a city contractor license and sometimes a plan review first.

An apartment window replacement permit on a building of five or more units usually comes from the city's commercial side, because those buildings fall under the commercial building code. Some cities also require a city contractor license for that work. JMB Builders checks both, plus any plan review, and pulls the permit before the windows are ordered. Twin Cities metro to St. Cloud.

- City license and permit rules checked first
- Permit pulled before ordering
- Commercial code for 5+ unit buildings
A building with five or more units is not a house in the code's eyes. Minnesota applies the commercial building code to it and, for work on an existing building, the state's existing-building rules, not the residential code. In practice, a window replacement permit goes through the city's commercial permit desk, and the application can ask for more: window schedules, product data, sometimes a plan review. A few cities ask for drawings unless the replacement is the same size.
City contractor licensing is the second check. Minnesota has no state license for work on buildings over four units, and our state residential license does not cover that work. Some cities fill the gap with their own commercial contractor license; St. Cloud and Hopkins are examples, as we understand their rules, and others vary. So before we bid a building of five or more units, we check the city's contractor licensing and permit rules for that building.
The permit also drives the window choices. The building code generally requires bedroom windows below the fourth story to be emergency escape openings, and windows high above grade with low sills generally need opening-control devices. The building official decides how those rules apply to replacement windows. We review each opening before the order so the product fits the rules the city will inspect to.

Apartment Window Replacement Permit — Commercial Code and City License: questions, answered
Do I need a permit to replace windows in an apartment building?
Usually, yes. Most Twin Cities cities want a permit for replacement windows, and on a building of five or more units it is usually a commercial permit. We check the rules for that building and pull the permit before ordering.
Is an apartment window permit different from a house permit?
Often. Buildings of five or more units fall under the commercial building code, so the city may ask for a window schedule, product data or a plan review. Some cities want drawings unless the windows are the same size.
Does a contractor need a city license to replace windows in an apartment building?
In some cities. Minnesota has no state license for buildings over four units, and some cities, such as St. Cloud and Hopkins as we understand their rules, have a commercial contractor license. We check the city's licensing before we bid.
Does the state residential license cover apartment buildings?
No. The Minnesota residential license covers buildings of one to four units. Work on five or more units needs no state license, so the city's rules are what we check.
Do replacement windows in apartments have to meet egress rules?
The building code generally requires bedroom windows below the fourth story to be emergency escape openings, and replacement rules usually let a same-style window of the largest standard size that fits. The building official decides. We review each bedroom window before the order.
Who pulls the permit for apartment window replacement?
We do, with the owner's authorization, before the windows are ordered. Permit fees are a separate line on the quote.
