Can I Build a Shed Next to the Property Line?
Sometimes — you can build a shed close to the property line, but almost never on it. Accessory setbacks are typically 3 to 5 feet from side and rear lines, reduced for small sheds in some jurisdictions, and zero-lot-line sheds are commonly prohibited outright. Two other systems narrow the space further: fire rules, which demand a 1-hour-rated wall when a shed sits within about 5 feet of the line, and easements, in which nothing may be built at all. The setback is zoning's question; the survey is how you know where the line actually is.

The setback rules
The typical accessory setback is 3 to 5 feet from side and rear property lines. Small sheds — commonly those at or under 120 sq ft — get a reduced setback (sometimes 2 feet) in some jurisdictions. Building directly on the line is usually prohibited for detached sheds, and building in an easement is prohibited always, whatever the setback table says. The front yard carries its own rule: a shed must generally sit behind the front face of the house, inside the front setback the house itself obeys. All of these numbers are local; the zoning office's accessory-structure sheet is the document to read.
Fire and utilities
Within about 5 feet of the property line, fire separation enters: the shed wall facing the line typically needs a 1-hour fire rating with no unprotected openings, because a shed fire that close is the neighbor's house-fire problem. Utility and drainage easements override everything — no structure at all, because the utility's access is a recorded right. Drainage runs the other direction: the shed's roof water may not be directed onto the neighbor's lot. Many HOAs add screening or appearance rules on top of the city's.
Size and permits
Sheds at or under 120 sq ft (a 10x12) are permit-exempt in many jurisdictions; larger sheds take a building permit, and accessory height limits typically run 12 to 15 feet. Because 'close to the line' is where neighbor disputes start, a survey that stakes the actual line is cheap certainty — sheds have been moved, and occasionally demolished, over a foot of encroachment that a survey would have caught for a few hundred dollars. The sequence that works: survey, zoning sheet, then concrete.
The bottom line
Sheds typically need 3-5 ft side/rear setbacks (reduced for small sheds in some jurisdictions) — never build in easements; provide 1-hour rating within 5 ft of the line and verify with a survey.
