Minimum Frost Depth Northern Michigan 3

[TBell47]

Can someone tell me either the minimum frost depth of footers and footings for northern Mighigan?
OR
An online site where I might find this information?

Thank you.

Your best bet is to contact your local building inspector, or building permit office. They will be able to give you the answer to assure compliance with local building code.

Anytime I've had the same question for various areas around the country, the local inspectors have been very helpful.

If you need "actual" frost line local plumbers or dirt work companies may help.

Good luck

Hi TBell47,

As a start, according to NAVFAC DM-7.1 pg 7.1-42 it's 5'.
