Property Assessments in Concord

The Contra Costa County Assessor values all Concord properties each year. When you buy a home, the purchase price becomes the assessed value. Each year after that, value can increase up to two percent under Proposition 13. This protects homeowners from big tax spikes.

New construction adds to your assessed value. If you build an addition, remodel, or add structures, the Assessor increases your value. Building permits trigger reassessments. You get a supplemental tax bill for the added value mid-year.

Some transfers avoid reassessment. Parents can transfer a primary residence to children without a new value if they file within three years. Grandparent to grandchild transfers also qualify in certain cases. This keeps the old assessed value.

Homeowners over 55 can transfer their base value to a new home. Buy within two years of selling. The new home must cost the same or less. File the claim within three years of purchase. This prevents a tax increase when you downsize.
