The name is identical with the word heimr which means "home", "homestead", or "farm".

The white design is reminiscent of boats, fjords, seeds, and church spires, all of which are a part of the culture of the municipality.

Heim Municipality is located along south side of the Trondheimsleia strait along the Trøndelag/Møre og Romsdal county border.

The rugged coastline contains many fjords including the Arasvikfjorden, Halsafjorden, Hemnfjorden, Skålvikfjorden, Snillfjorden, Valsøyfjorden, and Vinjefjorden.

The municipal council (Kommunestyre) of Heim is made up of 23 representatives that are elected to four year terms.
