It depends
Sometimes, depending on the project

Quick answer
Madison requires a permit for a shed or accessory building that is over 150 square feet, heated, or less than ten feet from dwelling units on the same property. A shed that is 150 square feet or less, unheated, and ten feet or more from dwelling units needs no permit, but it still has to meet the city's size and placement rules. The Development Services Center permit chart answers "Maybe. See shed page." for "Shed - build or replace" and sends the question to Zoning. Construction documents are required if the shed is over 150 square feet, heated, within 10 feet of another structure, or more than one story.
Typical threshold: shed or accessory building floor area; heated sheds and sheds within ten feet of dwelling units on the property need a permit at any size.

How to apply in Madison
A residential shed permit application, once the shed is large enough to require one, is a set of construction documents that show what will be built and prove it meets the adopted residential code. In practice that means a written permit application, a scaled site plan locating the shed and its distances to the property lines, and construction documents covering the shed's foundation or anchoring system and its framing.
What most shed permit applications include:
- A written permit application identifying the proposed work and describing the property by its address or legal description, filed with the building department before construction begins (IRC R105.3).
- A scaled site plan showing the shed's size and location and its dimensioned distances to all property lines so required setbacks can be verified before the permit is issued (IRC R106.2).
- Construction documents showing the shed's foundation: freestanding accessory structures at or under the code's small-structure size and eave-height limits (600 square feet and a 10 foot eave height in the model code) are exempt from continuous footings but must still be shown supported on undisturbed soil or engineered fill and anchored to resist wind-induced uplift and overturning (IRC R403.1).
- Where the shed does sit on a continuous foundation with a wood sill plate, anchor bolt or approved strap details tying the sill plate to the foundation (IRC R403.1.6).
- Roof framing details showing the rafter-to-wall or truss-to-wall connections, since even a shed exempt from continuous footings must be anchored to resist wind-induced uplift and overturning (IRC R403.1; R802.11).

Inspections and closing out your permit
A permitted shed is inspected in stages as it goes up: the foundation or the anchors that hold it down before they are covered, the framing before it is enclosed, and a final inspection once the shed is finished. Each stage checks the items that would be hidden or unsafe if skipped.
- Foundation or anchor inspection: called after any required footings, piers, or ground anchors are set and any forms or reinforcing steel are in place, but before concrete is placed, so the foundation or anchoring system can be verified before it is covered (IRC R109.1.1).
- Frame inspection: after the shed is framed, sheathed, and braced, the inspector checks the framing, bracing, fasteners, and the roof connections that resist wind uplift, before those elements are covered (IRC R109.1.4 frame inspection; R403.1 anchorage).
- Final inspection: made after the permitted work is complete and before the shed is used; work may not proceed past any inspection stage without the building official's approval (IRC R109.1.6 final inspection; R109.4 approval required).
- For a pre-fabricated or kit shed, the manufacturer's installation instructions must be on site at the time of inspection so the inspector can confirm the anchoring and assembly match the design (IRC R106.1.2).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Madison permit portal or by phone at 608-266-4551.

- How long does a shed permit take in Madison?

- Where do you apply for a shed permit in Madison?
- You can apply through the Madison permit portal or contact the City of Madison Building Inspection Division, Department of Planning and Community and Economic Development directly. The links are listed on this page.
- Can a homeowner pull a shed permit themselves in Madison?
- Under Wisconsin law (Wis. Stat. 101.654(1)(a) and (1)(b); Wis. Admin. Code SPS 305.31(1), SPS 320.09(9)(a)2., 3. and 4.; Wis. Stat. 101.65(1m) and (1r); Wis. Stat. 101.862(4)(a); Wis. Stat. 145.06(4)(a)): A Wisconsin homeowner may pull the permit and do the work on their own dwelling. The general rule is that nobody may obtain a building permit for a one- or two-family dwelling without a DSPS dwelling contractor certification plus a dwelling contractor qualifier credential, but the statute exempts an owner of a dwelling who resides or will reside in the dwelling and who applies for a building permit to perform work on that dwelling. Neither the statute nor the implementing rule places any cap on how often that exemption may be used, and Wisconsin has no counterpart to Florida's one-year resale restriction. The trade-off is a disclosure: the permit issuer must have the owner sign a statement warning that if the owner hires a contractor who is not bonded or insured, the owner may be held liable for injury or property damage arising from the work and may be unable to collect damages from that contractor. Trade licensing carries its own homeowner carve-outs, both defeasible by local ordinance: a residential property owner may do electrical wiring on premises the owner owns and occupies as a residence, and a property owner may do plumbing work in a one-family building owned and occupied as the owner's home.
