Before you get quotes
A full replacement is new construction, so plan on Madison’s deck permit and the inspection after the holes are dug. Do not assume old footings meet the 48-inch depth the city requires. If the new deck is taller than three feet, setbacks and a site plan apply.
- Inspection of old footings
- Permit for the new structure
- Demolition and disposal
- Same or new footprint

Questions about deck replacement
Are you the deck builder?
An independent builder you hire directly. This is a Madison-area referral site, so we pass your request along; we do not build, price or guarantee anything.
Will the old footings pass?
Only if they meet the current 48-inch depth and the inspector agrees. Plan for new ones if you are unsure.
Does a replacement need a site plan?
In Madison, a site plan is needed when the deck is over three feet high.
Is a permit needed?
In Madison, yes: the city says you need a permit to build a deck. Fitchburg requires one for decks 24 inches or more above grade, Sun Prairie wants a drawing and site plan, and Verona lists a $300 deck permit. Each Dane County community sets its own rules.
