What to check on your notice
If your 2026 notice shows a higher value than last year, ask why. The typical Union City home lost 6.4% over the same stretch. A higher number can still be right for a specific home, for example after a remodel, but the county board of tax assessors should be able to explain it.

Deadline and where to file
Union City values are set by the local county board of tax assessors. 45 days from the date the assessment notice was mailed. Mailing dates vary by county, so the deadline does too.
Reading this in fall 2026? Most counties mailed 2026 notices in spring or summer, so the 45-day window has closed for nearly everyone. A few counties mail late, so check the mailing date on any 2026 notice you hold. Otherwise your next realistic chance is the 2027 notice, mailed in spring or summer 2027 for January 1, 2027 values. Watch your mail and count 45 days from the date on the notice, not from when you open it.
