Vallejo updates ADU ordinance; city lists October 8 effective date

See the dated update below for the reported milestone and timing.

Source: City of Vallejo, ADU Ordinance Update · checked Oct 10, 2026 · Coverage updated Oct 10, 2026

Vallejo adopted Ordinance 1890 N.C.(2d), replacing Municipal Code Chapter 16.303 for accessory and junior accessory dwelling units. The city lists October 8, 2026 as its effective date and says it sent the ordinance to the state housing department on September 11. The signed ordinance certifies adoption on September 8; the city's project page instead says September 9. That one-day difference remains unresolved. The ordinance sets local standards and review procedures; it does not approve an individual home. Residents considering a project should consult the adopted text and city planning staff.

How we know (2 sources)

Dated source evidence; the project may have changed since then. An approval does not establish construction or an opening.

Summary

City project page reports adoption, October 8 effective date and September 11 HCD transmission. It states September 9 adoption, one day later than the signed ordinance.
