Sahuarita, AZ Fence Regulations: Neighbor Fence Rules (2026)

Unlike states with mandatory fence-sharing statutes, Arizona leaves boundary fence costs and responsibilities entirely to private property owners. There is no Sahuarita Town Code provision requiring neighbors to split the cost of a shared boundary fence or to contribute to maintenance of an existing fence, even if both properties benefit from it. If a property owner in Sahuarita wants to build a fence on the property line, they should first obtain a survey to confirm the exact boundary location, then discuss plans with the adjacent neighbor as a courtesy. Building a fence entirely on one's own property avoids boundary disputes but may sacrifice usable yard space. A fence built directly on the property line without the neighbor's agreement may create conflicts if the neighbor later disputes the boundary or objects to the fence's appearance on their side. The Sahuarita Building Safety Division requires permits for masonry block walls exceeding six feet in height, and all fences must comply with zoning setback requirements. In HOA communities like Rancho Sahuarita, boundary walls are typically installed by the developer during subdivision construction using a uniform block-wall design. Maintenance of these developer-installed walls may be addressed in the CC&Rs, often assigning responsibility to the homeowner on whose lot the wall sits or splitting responsibility where the wall is on the property line.
