King County reaches from the Seattle urban core out to the Cascade foothills, and King Conservation District covers most but not all of it. Its own service area is 34 cities plus unincorporated King County, excluding Enumclaw, Federal Way, Milton, Pacific and Skykomish, which do not take part in the district. It runs free wildfire assessments of its own on top of the usual free technical help and property visit. WSU Extension is at Renton, and coached planning courses have run at Skykomish and Preston. DNR's South Puget Sound Region at Enumclaw covers forest practices.

Why Sierra Log & Timber cares about your vacant land
Sierra Log & Timber mills cedar log and timber home packages in Chico, California. A good part of our working week is spent with people who have just bought land, and the same thing happens every time: the grants, the chipping days, the defensible space visits and the permit desks are all real, and all scattered across a dozen county websites that do not link to one another. So we put them in one place and left it open. You do not have to be building a log home to use this, and reading it signs you up for nothing.
Nothing local is recorded for King County yet. What is on this page reaches it from the Washington and national listings above, which is worth knowing before you ring anybody: the help is real, but the desk answering is not in the county. We would rather say that than pad the page. If you know of something here that belongs on it, the second panel below is the fastest way to tell us.
Building on rural land in King County
What applies here, in Washington and in this county, each line with the source it was read from.
Where the building permit comes from
King County Permits (Department of Local Services) issues building permits here.
Washington has adopted the 2021 Washington State Residential Code, the 2021 International Residential Code with state amendments, effective March 15, 2024.
A county or city issuing a residential building permit for a parcel mapped as high or very high wildfire hazard must apply Washington's wildland-urban interface code, which the State Building Code Council adopted as the 2021 Washington Wildland-Urban Interface Code effective March 15, 2024.
Counties and cities enforce the state building code under RCW 19.27.050, so a dwelling on unincorporated land is permitted by the county building department, and a county without one must contract with another county, city or approved inspection agency.
A person working on property they own, or on their own residence, is exempt from contractor registration under RCW 18.27.090(12), unless the work is done in order to sell, demolish or lease the property.
Does Sierra Log & Timber run any of these programmes?
No. Every organisation and programme on this page is run by somebody else: a county office, a state agency, a nonprofit, a utility or a tribe. We collect them, check them and publish them, and that is the whole of our part in it. What we do ourselves is mill cedar log and timber home packages in Chico, California.
Is this free to use, and does using it sign me up for anything?
The directory is free and reading it signs you up for nothing. The two panels below are the only places on this page that ask for an address, both are optional, and they do different jobs: one tells you when this county's listings change, the other tells us that something here is already wrong.
Numbers change and programmes run out of money. Leave an address and it is held against the King County page so you can be told when a listing here is added, changed or removed. No account.
What is stored is your address and which county page you left it on, and nothing else: no name, no location, nothing about what you read. It is used for that one notification and for nothing else, it appears nowhere on this site, and this site cannot read the list back. Nothing has been sent to any address yet, because the notices are not built; when they are, every message will say how to stop them.
Something on this page is wrong?
Numbers change, offices move and programmes run out of money. If something on this page is wrong, tell us and a person will check it.
What you send goes to the people who maintain this directory and appears nowhere on this site. Your email is used to reply to you and for nothing else.

The phone is the California state office in Davis. Programmes are applied for at the county NRCS Service Center, and enrolment requires a farm or tract number via the Farm Service Agency.
Free topographic maps and downloads through topoView and The National Map. Worth an hour before you buy or rebuild: contours, watercourses, roads and the shape of the slope a house would sit on, at no cost and without asking anyone's permission.
There are three kinds and they answer different questions. The historical collection is scanned quadrangle maps published between 1884 and 2006, which is how you find the old track, the old ditch and the building that is no longer there. US Topo is the current national series. OnDemand topos you build yourself, choosing the area, the scale, the format and what goes on the map. Historical maps and current US Topo sheets from 2009 onward download free through topoView in several formats, and if you would rather have paper, maps can be printed to order.
Free, from USDA Natural Resources Conservation Service
Free soil and parcel mapping tool for any parcel: septic suitability, building limitations and vegetation.
The way it works is that you draw an area of interest on the map and everything then reports against that shape, so you get the soils under your own boundary rather than a county average. Behind it is the full soil survey report rather than a summary, kept current, and it is meant for land use and management decisions, which is the question you are asking when you wonder whether a septic system or a foundation will work where you want it. You can take the spatial and tabular data away for use in mapping software. NRCS publishes a short four step guide, a guide to the maps, reports and tables it can produce, and a separate note on drawing your area of interest on a phone, which is the one to have with you when you are standing on the ground.
