Can You Bury Your Pet in Your Yard in Washington State?

You can bury a pet in your yard in Washington state, as long as the grave meets the conditions in WAC 246-203-121: at least three feet of soil cover, at least 100 feet from any water source, out of flood-prone ground, and sited so it will not contaminate groundwater or a public drinking water supply.¹ A few other steps, like calling 811 and checking with your landlord or HOA, also apply before you dig.

What the State Rules Require

WAC 246-203-121 sets five conditions for burying an animal on your property:

Every part of the animal must be covered by at least three feet of soil.
The site must be at least 100 feet from any well, spring, stream, or other surface water.
You cannot bury in a low-lying area prone to seasonal flooding or in a 100-year floodplain.
The burial cannot be done in a way likely to contaminate groundwater.
Burial is prohibited within the sanitary control area of a public drinking water source.

The three-foot depth is the condition most often shortchanged, and it matters. A shallow grave invites raccoons, coyotes, and other scavengers to dig up the remains, which creates a health hazard and an experience no one wants to come home to.¹

The 300-Foot Figure Is for Livestock, Not Pets

If you search for Washington burial rules you may see a 300-foot setback cited. That number comes from WAC 16-25-025, which governs disposal of dead livestock: horses, cattle, sheep, goats, swine, poultry, and similar farm animals. Dogs, cats, and other household pets are not livestock, and the livestock rule does not apply to them.²

The livestock chapter also imposes a 300-foot setback from any residence you don’t own, a 50-foot setback from property lines, and a 72-hour disposal window. None of those apply to a pet burial. The 100-foot water setback is a floor, though, not a target. Burying farther from wells, streams, and property lines is always a safer practice.

Call 811 Before You Dig

This is the step most pet owners overlook. Digging anywhere in Washington without first requesting a utility locate is against state law under RCW chapter 19.122, including digging on your own property for any reason.³ Hitting a gas line, electrical cable, or water main can cause injury, property damage, or an outage for your neighborhood.

At least two business days before you plan to dig, call 811 or submit a request through the Washington Call Before You Dig website. Outline the dig area with white paint beforehand and describe the work. Utility companies will send someone to mark the approximate location of underground lines using color-coded paint. The service is free. Skipping it can bring fines, charges for repair costs, and criminal liability.³

Two business days is a hard wait when you are grieving. The alternative is worse: a damaged gas line alone averages $400 to $800 in repair costs and can run far higher if a break causes a fire or evacuation.

Extra Care if Your Pet Was Euthanized

Most veterinarians euthanize pets with sodium pentobarbital, a barbiturate that remains in the body after death. If a coyote, eagle, or neighborhood dog digs up and consumes any of the remains, the drug can kill them. The FDA requires pentobarbital products to carry a label warning that euthanized animals be disposed of by deep burial, incineration, or another compliant method specifically to prevent wildlife poisoning.⁴

The three-foot depth helps, but add precautions when burying a euthanized animal. Choose firm, compactable soil, place heavy stones or pavers over the filled grave, and consider laying chicken wire a few inches below the surface. These steps protect wildlife and any pets your neighbors let outside.

When Local Rules, HOAs, or Landlords Say No

State law sets the floor. Local governments in Washington can adopt stricter rules, and the state regulation itself acknowledges that more stringent federal, state, or municipal standards take precedence.⁵ Some cities and counties increase setback distances, restrict burial in certain soils, or prohibit backyard burial in densely populated zones. Check with your city or county health department before you dig. Local health officers also have authority to require a specific disposal method if the animal died with a communicable disease that can affect humans.¹

Private agreements can block a legal burial too. If you live in a community with a homeowners’ association, the CC&Rs may prohibit burying animals on residential lots. Violations typically bring fines, and some associations will place a lien on your property for unpaid penalties.

Renters have a separate problem. Washington’s Residential Landlord-Tenant Act requires tenants not to intentionally or negligently destroy, damage, or remove any part of the property, and requires restoring the premises at move-out.⁶ Digging a three-foot grave in a landlord’s yard without permission is a clear violation. Get written consent first, or you risk your security deposit and a damage claim.

If Burial Isn’t an Option

Backyard burial is not workable for every property or every owner. Yards can be too small, soil too rocky, landlords unwilling. Several other options exist in Washington:

Private cremation returns your pet’s ashes to you individually, typically $200 to $600 or more depending on size.
Communal cremation groups multiple animals together without returning ashes and is the most affordable professional option, generally $50 to $200.
A pet cemetery handles burial in full compliance with regulations and provides a permanent, marked plot, with total costs for plot, casket, and services generally $300 to $2,000 depending on location.

Your veterinarian’s office is usually the best starting point. Most clinics work with local cremation and cemetery services and can walk you through the choices. Many will hold your pet’s remains in cold storage for a day or two while you decide, so the decision does not have to be made under pressure.
