Automatic Door Installation in Lethbridge
In Lethbridge, a commercial alteration that touches a fire separation or a barrier-free route needs a building permit before work starts. We plan your automatic entrance around that, then install and test it.
Call our Calgary team403-650-5232What the City of Lethbridge asks for on a commercial alteration
The City requires a building permit before interior alterations in an existing commercial building, including alterations involving fire separations. Barrier-free design has to be considered and included where it applies, and the application needs three sets of construction drawings. Purely cosmetic work doesn't need a permit.
A new automatic entrance often touches all of that: the wall, the path of travel and sometimes a fire separation. We sort out what the drawings need to show before the install date is booked, so the permit doesn't hold up the job.

Does my Lethbridge automatic door project need a building permit?
If it involves interior alterations to a commercial building, such as wall changes or anything touching a fire separation, the City of Lethbridge requires a permit before work starts. A like-for-like operator swap on an existing door is less clear-cut, so check with the City's building permit office.
What drawings does the City of Lethbridge ask for?
Three sets of construction drawings for a commercial interior alteration, showing where barrier-free design applies. For a new business, an occupancy permit with a $250 base fee is also needed before the business licence is issued. We can supply the door and hardware details for your drawings.
Do you come to Lethbridge for installs and service?
Yes. Lethbridge work is planned from our Calgary head office, about two hours north. We book installs and service visits so the technician arrives with the parts and the door's records, and we can combine visits for buildings with several doors.
