Jurupa Valley FAQ
Will I pay impact fees on a 700 sq ft ADU in Jurupa Valley?
No. Sec. 9.240.290(H)(2)(a) exempts all ADUs under 750 sq ft from impact fees, conforming to Cal. Gov. Code Sec. 66314(f).
How are fees calculated for a 900 sq ft ADU?
Impact fees are proportional. If your primary dwelling is 1,800 sq ft and the ADU is 900 sq ft, you pay 50% of the impact fee that would apply to the primary (per Sec. 9.240.290(H)(2)(b) and Cal. Gov. Code Sec. 66314(f)(1)).
Do I need a new water meter for my ADU?
Not if the ADU converts existing space — Sec. 9.240.290(H)(1) allows shared water and sewer connections. New detached construction may require a separate connection subject to a proportionate fee per Cal. Gov. Code Sec. 66324.
