What Is a Setback?
A setback is a minimum required distance between a structure or animal housing and a reference point โ typically a property line, neighboring structure, street, or your own dwelling. In livestock ordinances, setbacks serve two purposes: they create buffer space for odor and noise dispersion, and they prevent structures from being built so close to property lines that they create disputes or encroach on shared easements.
Setbacks are measured from the nearest point of the enclosure or coop to the reference point โ not from the center of the structure. A 10-foot setback means the outer wall of the coop must be at least 10 feet from the property line.
Types of Setbacks in Livestock Ordinances
Most livestock ordinances specify multiple setback types, each measured from a different reference point. You must satisfy all of them simultaneously:
- Property line setback: Distance from any property line โ front, rear, or side. Most common. Typically 10โ25 feet for chickens, 25โ75 feet for goats.
- Adjacent dwelling setback: Distance from the nearest wall of any neighboring house or occupied structure. Often 25โ50 feet. This can be more restrictive than the property line setback on small lots.
- Own dwelling setback: Distance from your own house. Less common but exists in some codes โ typically 10โ20 feet. Intended to keep odor away from your living space.
- Well/water source setback: In rural areas with wells, coops may need to be 50โ100 feet from any potable water source to prevent runoff contamination.
Shared Fence Lines and Zero-Lot-Line Properties
The most common setback confusion involves shared fence lines. If you and your neighbor share a fence on the property line, a 20-foot setback means the coop must be 20 feet from that shared fence โ not 20 feet from your neighbor's house. The property line is the fence line, and the setback is measured from there.
On zero-lot-line properties (where one side of your structure sits directly on the property line), the side setback is effectively zero โ but most livestock ordinances still impose a minimum setback from any lot line, which can make side-yard placement impossible. Rear yard is almost always the only viable option on zero-lot-line lots.
When the Math Doesn't Work
On smaller urban lots, satisfying all setback requirements simultaneously can be geometrically impossible. A 50ร100 foot lot with a 25-foot rear setback from the back property line and a 25-foot setback from the adjacent neighbor's dwelling (measuring from your fence to their house) may leave a corridor of 10 feet or less โ too small for any practical coop.
If you can't meet setback requirements with your current lot configuration, two options exist:
- Apply for a variance โ a formal request to reduce a specific setback requirement for your parcel. See our variance application guide.
- Redesign the enclosure โ some cities allow smaller "micro-coops" (under a certain square footage) to have reduced setback requirements. Check your code's definition of "accessory structure."

|---|---|---|---|---|
| Chickens | 10โ25 ft from lot line | 10โ20 ft | 25โ50 ft | 25โ50 ft typical |
| Ducks | Same as chickens | Same as chickens | 25โ50 ft | 25โ50 ft typical |
| Goats | 40โ75 ft | 25โ50 ft | 50 ft | 50โ75 ft typical |
| Rabbits | 10 ft (if applicable) | 10 ft (if applicable) | Rarely specified | Rarely specified |
| Beehives | 10โ25 ft + flyway fence | 10โ20 ft | 25 ft | Varies |
