When you are buying from another state, you might see a house once, on a weekend trip, with good light coming through the trees. The listing sheet you rely on is a marketing document, not a disclosure. The good news is that most of what you need to know about a property in Kitsap, Pierce, or Mason County is public, free, and searchable from your couch. Here are the six records to pull before you book the flight or write the offer, and the one place where the free maps stop being trustworthy.
Start with the parcel number, not the listing
Every piece of land in Washington has a parcel number, sometimes labeled a tax account number. That one string of digits is the key to every other search in this article. Start at the county assessor's parcel search or GIS map rather than a listing portal, enter the street address, and copy the parcel number into a note. You will paste it into several more searches.
Raw land and rural listings often come with only a parcel number and no street address. That is not a dead end: the county portals search by parcel number or owner name as well.
What the assessor screen quietly tells you
Read the legal description first. A short reference to a lot and block number means the land sits in a recorded plat, laid out by survey when the subdivision was created. A paragraph of compass bearings and distances is a metes-and-bounds description, which usually signals older, rural land with less certain edges.
Then look at the sales history. Frequent turnover, such as several sales in a few years, is not necessarily a problem, but it is a question worth asking. Finally, read the shape of the assessed value over time rather than the dollar amount. A sudden jump often reflects an addition or upgrade the assessor finally recorded, and that improvement is exactly what you will want to match against the permit record.
Zoning: can you do what you're planning?
Many people relocating here have a plan for the land: a shop, a second dwelling for a relative, space for an RV, a rental unit. Far fewer confirm the zoning permits that plan before closing. On the county GIS map, turn on the zoning layer and note the designation and its minimum lot size. That minimum tells you whether five acres could ever be split into two.
A common example right now is Washington's rural ADU law. House Bill 1345, Chapter 231, Laws of 2026, took effect June 11, 2026 and lets counties allow one detached accessory dwelling unit on rural land within strict limits. It is opt-in by county, and Kitsap, Pierce, and Mason each have their own existing ADU rules. Do not buy acreage on the assumption that a second home is allowed. Call the county planning department and ask about that specific parcel.
Permits: did anyone ask permission?
The finished basement, the converted garage, the deck: someone built them, and the question is whether the county knew. Each county has a permit search, usually under community development or planning and public works, and the parcel number pulls up the history. You are matching records to what you saw. A listing that advertises more bedrooms than the septic design on file, with no permit for the addition, is a conversation to have before the offer.
Learn the status column. Final means the work was inspected and signed off. Expired means a permit was pulled and the final inspection never happened. Open or active on a project finished years ago tells the same story with a friendlier label. Work done without permits can leave the owner on the hook to open it up and brought to current code at the current owner's expense, and it can complicate financing, insurance, and your eventual resale.
No permits at all on a recently built house is not proof of anything. Smaller counties digitized records at different times, and some older paper files never made it online. Call rather than assume.
Septic and well files live somewhere else
Buyers relocating from urban areas often have never owned the systems that bring water in and take waste out. On many properties here, both are yours to maintain and eventually replace. Septic records are not kept by the assessor. They sit with the local health jurisdiction: Kitsap Public Health District, the Tacoma-Pierce County Health Department, or Mason County Public Health.
Pull three things: the as-built diagram that locates the tank and drain field, the number of bedrooms the system was designed for, and when it was last inspected or pumped. Adding a bedroom to the house does not add capacity to the septic system. For wells, the Washington Department of Ecology keeps a searchable database of well reports with the original depth, drilling date, and tested yield. Treat an old yield figure as history, not a promise, and test the well during your inspection period.
Is the property in a flood zone?
This is the record to check first if you only have ten minutes. Enter the address in FEMA's Flood Map Service Center to get the flood zone. Zone X is outside the special flood hazard area. Zones A and AE are inside it, the area with a 1% annual chance of flooding, and a federally backed or regulated lender will require flood insurance there, which changes your monthly payment.
Then go back to the county GIS map and turn on the hazard layers: landslide, steep slope, liquefaction, wetlands and critical areas, and tsunami inundation if you are near the water. Critical areas and wetlands can limit where you are allowed to build or add on. Hazard modeling gets updated, so make sure you are looking at the current layer.
Washington now treats flood risk as something even renters should hear about. Under Substitute Senate Bill 6237, leases entered into after December 31, 2026 must include a disclosure that the property may be in a flood hazard area. If renters get that notice, a buyer spending several hundred thousand dollars should look for themselves. A flood zone is not automatically a no. It is an insurance quote, possibly an elevation certificate, and sometimes a negotiating point.
Why the county map isn't a survey
County GIS parcel lines are administrative drawings made for assessment and taxation. They are not legal boundaries, the portals usually say so on the page, and they can be off by several feet or more. The classic mistake is closing, building a fence on the line the map shows, and learning from the neighbor's survey that the real corner is somewhere else.
The map also rarely shows easements: a utility corridor, a shared driveway, or a neighbor's recorded right to cross your land. Those live in recorded documents that appear in the title commitment once you are under contract. Use the free maps to find questions, then use a survey and the title commitment to get answers.
The four-minute call, and what to do next
One step is not in any database: call the county planning department and ask whether anything is open on the parcel, such as a permit, a code enforcement case, or a violation. It takes minutes and costs nothing. Taken together, these six records take about 45 minutes on a property you are serious about, and they turn your first visit into a confirmation trip instead of a discovery trip. Use the map to see where a property sits relative to towns and services, check connectivity at the address in the internet guide, and add the records check to your moving checklist before you browse current listings.
