Glendale FAQ
Does Glendale charge an ADU impact fee?
Streets impact fees do not apply to ADUs because state law (Ariz. Rev. Stat. 9-461.18) prohibits requiring street improvements. Glendale does charge standard building permit fees scaled to construction valuation, and unlike many cities, requires a separate water meter and new tap for every ADU, which generates meter and connection fees.
Why is Glendale's ADU water fee higher than other Arizona cities?
Glendale uniquely requires every ADU to have its own city water meter with a new tap to the water main in the street or right-of-way. Most Arizona cities permit ADUs to share the primary dwelling's meter and service, avoiding new connection fees. Plan for separate water meter and tap charges in your Glendale ADU budget.
