Do you need a permit to build a fence in Milwaukee?
Yes. Milwaukee has no height below which a fence is permit-free: the Department of Neighborhood Services (DNS) checklist marks both new fences and replacement fences as needing a permit, at any height. The good news is the price. A one- or two-family fence permit is $60.40 in total: the $25 fence fee from MCO 200-33-14.5, a $0.40 training and technology surcharge, and a $35 processing fee. That figure comes straight from DNS's residential fence requirements sheet (updated March 2026).
Build first and apply later and the fee may be quadrupled, which turns the $25 line into $100.
How tall can a fence be in Milwaukee?
Heights come from the zoning code, MCO 295-505-4-f, and depend on which yard the fence is in:
- Front yard: 4 feet. An ornamental metal fence may go to 6 feet if it is at least 50% open overall.
- Side yard: 4 feet solid, or 6 feet if the whole fence is open (chain link, wrought iron) or the part above 4 feet is at least 50% open, such as 4 feet solid with 2 feet of lattice. A solid 6-foot fence is allowed more than 10 feet from the side lot line.
- Rear yard: 6 feet.
- Along a side or rear street: 4 feet, except 6 feet along the side street of a rear yard, or an ornamental fence that is 50% open.
Near a corner, alley or driveway, opaque fences drop to 3 feet inside the vision triangle; DNS says the triangle's legs run 10 to 25 feet depending on the zoning district. A 2-inch gap at the bottom for rot clearance does not count against the height.

What does Milwaukee require of the fence itself?
Construction rules are in MCO 239-2. The posts and rails face your own yard and the outside face must be the same grade or better than the inside. Opaque fences 4 feet or taller must be anchored at least 30 inches deep, and every fence must withstand 30 pounds per square foot of wind. Wood posts are limited to 6 inches nominal and boards to 1x8. Doors, plywood sheets, pallets, chicken wire, snow fence and thin plastic are banned. If you build a new fence parallel to and within 6 feet of an old one, the old fence must come down within 10 days.
The fence may go right up to the property line but no part of it may sit on the neighbor's land, and the city does not settle boundary disputes. Find the line from your closing survey, the county plat search or a surveyor before you dig, and call Diggers Hotline (811) at least three business days ahead.
