Entombment is the practice of placing a deceased person’s remains inside a sealed, above-ground chamber instead of burying them in the ground. The chamber is called a crypt when it holds a casket and a niche when it holds an urn of cremated remains, and the building that houses crypts is a mausoleum. A single crypt in a shared community mausoleum typically costs between $4,000 and $8,000, while a private family mausoleum can run from $50,000 into the millions depending on size and materials. Families often choose entombment because it keeps the memorial accessible year-round, protected from weather, and permanent in a way a grave plot sometimes is not.
Types of Entombment Structures
The most common choice is a community mausoleum, a shared building containing rows of individual crypts used by many unrelated families. Indoor community mausoleums have climate-controlled hallways you can walk through to visit. Outdoor or garden mausoleums set their crypts into landscaped walls that face open air. Both styles are built around single crypts sized for one casket.
Couples who want to stay together often buy a companion crypt, which holds two caskets arranged end-to-end or side-by-side behind one shared faceplate. Some designs allow the first casket to be placed without disturbing future access for the second.
A private family mausoleum is a freestanding structure built for one family. A small two-crypt building starts around $50,000. A larger walk-in design with room for multiple generations can exceed $250,000, and the largest reach several million. Each one is essentially a custom construction project, so price reflects architectural design, stone selection, and site work on top of the crypts themselves.
Lawn crypts sit at or slightly below ground level under a thin covering of earth and grass. From the surface, they look like an ordinary grave, but the casket rests inside a pre-installed concrete chamber rather than directly in the soil. It is a hybrid that gives families above-ground containment without a visible structure.
A sarcophagus is a heavy stone container resting on a base, placed either inside a larger mausoleum or standing alone as a monument. These are the least common and most expensive option, generally reserved for prominent memorials.
Niches for Cremated Remains
Families who choose cremation first have a smaller-scale option. A columbarium is a structure built from small individual compartments called niches, each sized to hold one or two urns. Each niche is sealed with a faceplate of granite, marble, bronze, or glass, and the faceplate can be engraved with the person’s name and dates. The vocabulary is easier to keep straight once you remember that a niche holds an urn, a crypt holds a casket, a columbarium is a structure of niches, and a mausoleum is a structure of crypts. Many buildings contain both.
What Entombment Costs
A single crypt in a public indoor mausoleum averages $7,000 to $8,000 nationally. Public outdoor or garden mausoleum crypts tend to run cheaper, roughly $4,000 to $5,000. Both figures are in the same range as a traditional burial plot plus a grave marker, so the choice between ground burial and a community crypt is usually about preference rather than price.
Private mausoleums are a different financial category entirely. A basic two-crypt freestanding structure typically ranges from $50,000 to $125,000. A large walk-in family mausoleum can cost $250,000 to well over $3 million. Those figures cover construction and initial use but do not always include land, permits, or ongoing care.
Beyond the crypt purchase, expect a separate opening and closing fee each time the crypt is used. That charge covers the labor of sliding the casket in and sealing the chamber, and it commonly falls between $2,500 and $3,500. Engraving the faceplate, endowment care contributions, and administrative processing are usually billed on top of that.
Federal Protections When You Buy
The FTC’s Funeral Rule requires any funeral provider to give you a General Price List when you ask in person about goods, services, or prices. The list must itemize costs so you can compare options and pay only for what you want. A cemetery is a funeral provider under the rule whenever it sells both funeral goods and funeral services to the public, which many do.1Federal Trade Commission. Complying with the Funeral Rule
The rule’s main protection is simple. A provider cannot force you to buy items or services you do not want as a condition of getting the ones you do. The only non-declinable charge is a basic services fee that covers the funeral director’s overhead. Everything else, including the casket and the entombment service, must be available on an itemized basis. A cemetery that tries to bundle crypt purchase, opening fees, and a specific casket into one non-negotiable package is violating the rule.1Federal Trade Commission. Complying with the Funeral Rule
One detail catches families off guard. You can buy a casket from any seller, and the provider cannot add a handling fee or surcharge for accepting it. A “casket handling” charge imposed because you shopped outside the cemetery is specifically prohibited.1Federal Trade Commission. Complying with the Funeral Rule
One practical note on caskets. Some families assume they need a “sealer” casket with a rubber gasket for above-ground entombment, but many mausoleum operators actually break or remove the gasket seal before placing the casket in the crypt, because a hermetic seal in an above-ground environment can accelerate anaerobic decomposition and create pressure problems. Ask the specific cemetery about its casket requirements before buying one.
Paperwork the Cemetery Will Require
Before any entombment happens, the funeral director has to secure an authorization for final disposition from the appropriate authority. Most states follow the CDC’s Model State Vital Statistics Act, which requires the funeral director or whoever first takes custody of the body to obtain this authorization before any final disposition. It will not be issued until a physician or medical examiner has completed and signed the death certificate. The cemetery cannot accept the remains for entombment without that document.2Centers for Disease Control and Prevention. Model State Vital Statistics Act and Regulations
Separately, the cemetery will ask for proof that the family owns the specific crypt. That document is usually called a Right of Interment or Certificate of Ownership. Before scheduling, the cemetery matches the deceased’s legal name, date of birth, and date of death against its ownership record.
Who Has the Right to Decide
When the deceased left no written instructions about final disposition, the right to make entombment decisions follows a priority order rooted in common law. The surviving spouse holds first authority. If there is no surviving spouse, the right passes to adult children, then to parents, then to siblings. This order, sometimes called the right of sepulcher, can be overridden if the deceased named someone through a durable power of attorney or similar instrument that specifically grants control over final disposition. Family disputes over this authority are more common than people expect, and they can hold up the entire process. Settling it in writing while the person is still alive prevents most of the trouble.
How the Entombment Itself Happens
Once the paperwork is complete, the casket is transported to the mausoleum, usually by hearse. Families often hold a brief committal service at the crypt. Cemetery technicians then use mechanical lifts or rollers to slide the casket into the crypt opening, moving slowly to keep it level and centered.
Sealing happens in two stages. First, an inner seal closes the opening and provides primary containment. Second, the outer shutter, a heavy slab of marble or granite, is secured over the front. That faceplate is the visible surface families see on visits.
Engraving the name, dates, and any chosen inscription usually happens after the entombment, since the stone has to be in position before the engraver can work on it. Turnaround depends on the cemetery and the engraver’s workload. Temporary nameplates are common in the meantime.
Perpetual Care and the Long View
Most states require cemeteries to put a percentage of every crypt sale into a perpetual care fund, sometimes called an endowment care fund. The money is invested, and the returns pay for structural maintenance, grounds upkeep, and repairs. Required deposits vary by state but commonly fall between 8 and 15 percent of the sale price. The fund has to be held separately from the cemetery’s operating accounts so it cannot be spent on day-to-day expenses.
The system works while a cemetery is still selling plots and crypts, because every new sale adds to the fund. The math gets harder once a cemetery is full. From that point on, maintenance depends entirely on investment returns, and returns do not always keep pace with the real cost of stone repair, roof replacement, and landscaping over decades.
If a cemetery is abandoned or becomes insolvent, most states allow a county or municipality to take over the property, though local governments are often reluctant because abandoned cemeteries bring no income and ongoing costs. Cemeteries owned by religious organizations, families, or individuals are frequently exempt from state perpetual care requirements, so their long-term upkeep depends entirely on the owner’s resources.
If you are buying a crypt, ask the cemetery directly how much is in its perpetual care fund, who manages it, and what maintenance it covers. A well-funded endowment is one of the better signs that the structure will still be cared for long after the people who built it are gone. In many jurisdictions, a trustee who fails to maintain an adequate balance can face personal liability, and operating a cemetery without the required endowment is treated as a strict liability offense.
Estate Tax Treatment
Entombment and mausoleum costs can be deducted from a decedent’s gross estate for federal estate tax purposes on Form 706. The IRS allows a deduction for funeral expenses actually paid by the estate, including a “reasonable expenditure for a tombstone, monument, or mausoleum, or for a burial lot,” plus reasonable future care costs.3eCFR. 26 CFR 20.2053-2 – Deduction for Funeral Expenses
The deduction only exists on the estate tax return. Funeral and entombment costs cannot be deducted on the deceased person’s final individual income tax return (Form 1040) and are not deductible on the estate’s income tax return (Form 1041) either.4Internal Revenue Service. Publication 559 – Survivors, Executors, and Administrators
Two limits apply. The expense must be reasonable, so an estate claiming a $3 million mausoleum for a modest estate can expect IRS scrutiny. And the expense must be allowable under the law of the state where the estate is being administered.3eCFR. 26 CFR 20.2053-2 – Deduction for Funeral Expenses For most families, the deduction only matters if the estate exceeds the federal estate tax exemption, which is $13.99 million per individual in 2025. Estates below that threshold owe no federal estate tax regardless, so the deduction has no practical effect for them.
