No. Bakersfield has no mandatory foundation-bolting ordinance for existing single-family homes. Foundation anchoring is required for new construction and substantial alterations under the California Residential Code (CRC R403.1.6), which BMC Title 15 adopts by reference.

Yes. Voluntary retrofits follow CRC Appendix Chapter A3, the state's prescriptive cripple-wall and sill-plate anchorage standard. A building permit from the city is required, and a licensed contractor or engineer is recommended.

Voluntary cripple-wall and anchor-bolt retrofits under Appendix A3 are highly cost-effective; California's Earthquake Brace + Bolt grant program may apply.
