Building a deck in Chanhassen

Chanhassen has more lake frontage than most suburbs its size: Lotus Lake, Lake Minnewashta, Lake Ann, Lake Riley and Christmas Lake. A deck on a lake lot is planned around the view and the slope to the water. See lake decks for how we approach them.

Chanhassen deck permits and code

Start with the city’s building and housing permits page. In the Twin Cities, deck footings go at least 42 inches deep to get below frost, and decks more than 30 inches above grade need guards.

Todd’s crew frames every deck the way they frame a house, so it stays solid and level year after year.

Straight answers.

Do I need a permit for a deck in Chanhassen?

Most decks in Chanhassen need a building permit. The city’s building permits page lists what to submit; it’s linked below.

Do you build patios?

Yes. We build patios on their own or alongside a new deck, and a Luxury Pergola can go over either one.

Do you build decks on Chanhassen lake lots?

Yes. Lakeside decks on Lotus Lake, Lake Minnewashta, Lake Riley and other Chanhassen lakes are a big part of what we plan for: sight lines, sun and materials that stand up to the weather.

Can you add a pergola?

Yes. Todd is the Midwest dealer for The Luxury Pergola and installs them himself, on a deck or a patio.

Is DecksMN.com part of Carstensen Construction?

Yes. All of Todd’s deck work is now part of one Carstensen Construction site.
