Understanding Vault & Liner Requirements at California Cemeteries
Understanding Vault & Liner Requirements at California Cemeteries
Are burial vaults or grave liners required by law in California? The short answer is no—state law does not mandate the use of a vault or liner for burial.
However, there is a crucial distinction: most cemeteries DO require them as part of their specific rules and regulations.
Why Do Cemeteries Require Them?
Cemeteries typically require an outer burial container (vault or liner, also known as an OBC) for one primary reason: to maintain the integrity of the ground.
- Ground Stability: As a casket naturally decomposes over time, the earth above it can settle and cave in, creating an uneven, unstable, and unsafe grave site.
- Groundskeeping & Safety: A settled grave creates hazards for visitors and can damage the heavy equipment used for routine grounds maintenance.
- Appearance: Outer burial containers keep the landscape level, ensuring a well-maintained, dignified environment across the cemetery grounds.
Vault vs. Liner: What is the Difference?
While both options support the weight of the earth and groundskeeping machinery, they differ in construction and level of protection:
- Grave Liner: A basic outer structure (usually made of concrete) that covers the top and sides of the casket, resting on the bottom of the grave.
- Burial Vault: A fully enclosed container lined with materials like steel, bronze, or water-resistant resins. It seals the casket completely, offering reinforced structural strength and protection against water and soil intrusion.
Check with Your Chosen Cemetery
Because outer container requirements are determined by individual cemetery policies rather than state legislation, it is essential to review the regulations of your selected burial site beforehand. Note that this requirement often applies to the in-ground burial of cremated remains as well, which may require a specialized, smaller urn vault.
Key Takeaways
- State Law vs. Cemetery Rules: California law does not require outer burial containers, but private and municipal cemeteries almost universally mandate them for ground stability.
- Structural Differences: A grave liner provides basic structural support, whereas a burial vault offers a sealed enclosure for enhanced protection.
- Applies to Cremation: If you choose in-ground burial for an urn, the cemetery may require an urn vault to prevent ground settling.
