Can I Subdivide My Property in Puyallup?

If you own a large lot, you have probably looked at the back half and wondered whether it could be a second lot. Land is valuable here, and the state has spent the last few years making it easier to create more housing on existing lots. Whether your lot qualifies comes down to a handful of facts you can check before spending much.

The four questions that decide it

1. Zoning and lot size. Every zone has a minimum lot size. Both the new lot and what remains of the old one have to meet it. Puyallup's single-family zones run from RS-04 to RS-35, each with its own minimum.
2. Access. Each lot needs legal access to a public road, by frontage or a recorded easement of adequate width.
3. Utilities. Each lot needs water and sewer, or enough room and suitable soil for a septic system and a well or water connection.
4. Constraints. Steep slopes, wetlands, streams, and floodplains reduce the buildable area. A lot that is mostly buffer may not count.

If any one of these fails, the answer is usually no, or not without real expense.

Step one: who has jurisdiction?

Many properties with a Puyallup address are in unincorporated Pierce County. The city and the county have separate codes. Look up your parcel in the county's About My Property tool to see the jurisdiction, the zoning, and any critical areas.

• City of Puyallup: the municipal code is published at ecode360.com/PU4601, and applications go through the city's permit portal.
• Unincorporated Pierce County: the county's page on what is allowed in a zone links to the zoning code, and the Development Center information line is (253) 798-3739.

The ways to divide land

The new lot-splitting law

In 2025 the Legislature passed House Bill 1096, titled "Increasing housing options through lot splitting." It directs cities to create an administrative process for dividing one residential lot into two.

As summarized by a Washington chamber of commerce review of the law:

• Only one new lot can be created
• Both lots must meet the minimum size requirement
• The parent lot cannot itself be the result of an earlier split under this process
• The planning director decides, using clear and objective standards
• Utilities must be available, and access must be secured
• Lots that cannot be built on because of critical areas do not qualify

Cities have until May 20, 2027 to adopt it, or sooner if their comprehensive plan update comes first. Ask Puyallup's planning staff where the city stands. If you are not in a hurry, this may be the easier path once it is available.

What the process involves

For a short plat, expect roughly this sequence:

1. Pre-application conversation with the planning office.
2. Survey by a licensed land surveyor.
3. Preliminary application with a map of the proposed lots, access, and utilities.
4. Agency review: planning, engineering, fire, and the health department if septic is involved.
5. Conditions: required improvements such as utility extensions, frontage work, or drainage.
6. Final map prepared by the surveyor and recorded with the county.

It takes months, and sometimes more than a year. Costs add up from the survey, engineering, application fees, and any utility or road work the approval requires. Get estimates for each before you commit.

The alternatives to subdividing

Sometimes you can get what you want without creating a new lot.

• Build an ADU. Puyallup allows up to two on a qualifying lot, and state law says a city cannot bar selling an ADU as a condominium just because it was built as an ADU.
• Middle housing. State law now requires many cities to allow more than one home on a residential lot. Ask planning staff what your zone permits.
• Sell to a builder. A builder may pay more for the whole property than you would net from doing the split yourself.

Does it pay?

Run it like a business decision.

The piece people miss is the third line. Taking 8,000 square feet off your lot can lower the value of the house that stays. Sometimes the new lot is worth far more than that loss. Sometimes it is a wash.

Talk to a tax professional before you sell a lot you have split off. The tax treatment is not the same as selling your home.

What I would do first

Before paying a surveyor:

1. Look up your zoning and minimum lot size.
2. Measure whether two conforming lots fit.
3. Check for critical areas and floodplain.
4. Call the planning office with your parcel number and ask, "Is a split feasible here, and what would stop it?"
5. Ask a broker what a finished lot in your area sells for.

Those five steps cost almost nothing and answer most of the question.

Frequently asked questions

Can I split my lot in Puyallup?

Possibly. Each resulting lot must meet the zone's minimum lot size and have legal access and utilities. Critical areas and floodplains can reduce what is buildable.

What is a short plat?

A short plat is a small subdivision reviewed administratively. State law sets the default limit at four lots and allows cities to raise it to nine.

What is Washington's new lot-splitting law?

House Bill 1096, passed in 2025, requires cities to create an administrative process for dividing one residential lot into two. Cities must adopt it by May 20, 2027 at the latest.

Is subdividing worth it?

It depends on the value of the new lot compared with the cost of creating it and the value your remaining home loses from a smaller yard.
