Casa Grande, AZ Fence Regulations: Neighbor Fence Rules (2026)

Casa Grande Municipal Code § 17.52.140 requires that all fences be located entirely upon the private property of the person, firm or corporation constructing or causing the construction of the fence, unless the owner of the adjoining property agrees, in writing, that the fence may be erected on the division line between the two properties. That written-agreement requirement is the city's only mechanism for a shared boundary fence; absent it, a fence builder must keep the entire structure inside their own lot line. The same Article III of Chapter 17.52 that houses this rule also sets the height-measurement method in § 17.52.150(B), which allows the fence height on a property line to be measured from the finished grade of either side only when abutting property owners have made that same kind of joint written agreement.

Because both the location rule and the height-measurement exception hinge on a written agreement between neighbors, a homeowner planning a shared boundary fence should get the adjoining owner's consent in writing before applying for the building permit required under § 17.52.130, since the permit application is the point at which the city checks the fence's proposed location.
