Arizona follows a permissive approach to boundary fences. Under Arizona law (ARS 33-1261), adjoining landowners share the cost of maintaining boundary fences equally when both properties benefit from the fence. Glendale does not mandate which direction a fence faces. The finished or good side is customary but not legally required to face the neighbor.

Glendale regulates fence heights through the Unified Development Code (Chapter 35). Fences over 6 feet tall generally require a building permit. Front yard fences are typically limited to 3 feet in residential zones to maintain visibility. Side and rear yard fences may be up to 6 feet without a permit. Taller fences may be allowed with a permit and design review.

Glendale enforces strict pool barrier requirements under Chapter 32 (Swimming Pools) of the City Code and Arizona state law (ARS 36-1681).

Pool barriers are inspected during home sales and building permits.

Glendale requires building permits for retaining walls over 4 feet in height (measured from the bottom of the footing to the top of the wall).

Attached ADUs cannot exceed half the size of the primary dwelling or 1,200 square feet, whichever is smaller. ADUs must meet the same setback requirements as the primary single-family dwelling on the lot.
