Stockton is bound by Cal. Gov. Code §65852.2(f)(3)(A), which prohibits any local agency — including Stockton — from charging impact fees on an ADU under 750 square feet. ADUs of 750 sf or greater may be charged impact fees, but the amount must be proportional in square footage to the burden the primary dwelling unit imposes. Pre-2020 unpermitted ADUs being legalized are also exempt from impact and connection fees except where utility infrastructure is actually required.

Stockton FAQ
Do I pay impact fees on a Stockton ADU under 750 sf?
No. Cal. Gov. Code §65852.2(f)(3)(A) prohibits Stockton from charging impact fees, connection fees, or capacity charges on any ADU under 750 sf. Standard building permit and plan check fees still apply, but the impact-fee waiver is absolute and not within the city's discretion.
What if my Stockton ADU was built before 2020 without permits?
Stockton has a legalization program for ADUs and JADUs built before January 1, 2020 under Health and Safety Code §17920.3 authority. Homeowners legalizing those units are exempt from impact fees and from connection or capacity charges, except where new utility infrastructure (e.g., a larger sewer lateral) must actually be installed.
