What size shed needs a permit in Milwaukee?
A tool or storage shed needs no building permit if its floor area is 150 square feet or less and it sits at least 3 feet from every property line. That exemption is written into the city code itself (MCO 200-24-1.5-c) and repeated on the Department of Neighborhood Services (DNS) shed handout. A common 10x12 shed (120 sq ft) qualifies; a 12x16 (192 sq ft) does not. Wisconsin's Uniform Dwelling Code does not cover detached accessory buildings, so these are city rules, not state ones.
Exempt does not mean unregulated. The zoning code still applies to every shed: it must sit in the rear yard, or in a side yard outside the house's required side setback, never in a front yard. A shed is capped at 14 feet overall with 8-foot sidewalls, all accessory structures together may cover no more than 15% of the lot, and a lot may have no more than 2 accessory buildings (a detached garage counts).
How much does a Milwaukee shed permit cost?
Fees are flat and come from MCO 200-33. A shed of 150 sq ft or less that needs a permit (for example because it sits closer than 3 feet to a lot line) costs a $175 permit fee plus a $50 plan review fee. Anything over 150 sq ft is treated like a garage: $0.45 per square foot plus a $75 plan review fee. Every permit adds a $20 processing fee, and DNS adds a 1.6% training and technology surcharge to its permit and review fees.
- 150 sq ft shed 2 feet from the fence line: $175 + $50 = $225, plus $3.60 surcharge and $20 processing = $248.60.
- 200 sq ft (10x20) shed: 200 x $0.45 = $90, plus $75 review = $165, plus $2.64 and $20 = $187.64.
- 400 sq ft workshop: $180 + $75 = $255, plus $4.08 and $20 = $279.08.
Yes, a 200 sq ft shed costs less than a permitted 150 sq ft one; that is how the per-square-foot line works out up to about 333 sq ft, where $0.45 per sq ft plus $75 catches up with $225. Running power to the shed is a separate electrical permit pulled by a licensed electrical contractor ($100 minimum fee plus $25 processing).

Where can a shed go on my lot?
The zoning table sets the shed's side setback in a rear yard at 1.5 feet and its rear setback at 4 feet, reduced to 1.5 feet where there is no alley or no alley access. The DNS handout puts it as 18 inches from the property line, measured from the shed wall. Remember that the permit exemption separately requires 3 feet from every property line, so a shed tucked closer than that is legal under zoning but needs a permit. The building code also keeps a wood shed 10 feet from the house unless the facing walls have one-hour fire-resistant construction, which allows 3 feet. Sheds must sit on an approved hard surface, such as 3 inches of concrete or patio block on 3 inches of gravel, and be anchored as DNS approves.
How to Get a Shed Permit in Milwaukee

Confirm the floor area and the distance to every lot line. At 150 sq ft or less and 3 feet or more from all lines, no building permit is needed.
Check zoning placement
Place the shed in the rear yard or outside the side setback, keep it under 14 feet tall, and check the 15% lot coverage and two-building limits.
