Three Yelm rules that shape a remodel early

  1. The Yelm rule

    Gopher soils and a summer survey window

    The Mazama pocket gopher has been protected under the federal Endangered Species Act since April 2014, and Yelm screens applications on soils tied to it, such as Nisqually loamy fine sand and Spanaway gravelly sandy loam. Field visits count only between June 1 and October 31, two of them at least 30 days apart, and they cover the whole parcel. Building inside the footprint of an existing structure, or more than 300 feet from mapped gopher soils, can release a project from review.

    What we do

    When an addition or ADU steps outside the existing footprint, we schedule the design around the June 1 to October 31 survey season.

  2. The Yelm rule

    Yelm Creek, Thompson Creek and high groundwater

    Yelm's critical areas code sets a riparian habitat area 150 feet wide along Yelm Creek and Thompson Creek, and structures stay outside it unless the chapter allows otherwise. Frequently flooded areas cover both the FEMA flood maps dated October 19, 2023 and the zones Thurston County maps as high groundwater flood hazard; no development may sit within 50 feet of a high groundwater area's outer edge, or below a ground elevation two feet above its base flood elevation, whichever is less.

    What we do

    We check the city's critical area maps, the FEMA flood map and the county's high groundwater layer for your address before design.

  3. The Yelm rule

    A city over its own aquifer

    The code designates all of Yelm and its urban growth area as a highly susceptible critical aquifer recharge area. New development connects to city water and sewer, and each dwelling has a STEP tank that feeds the collection lines to the city's reclaimed water plant. The residential permit application asks for a site plan that shows where the septic or STEP tank sits.

    What we do

    Your STEP tank and water service go on the site plan we prepare for the permit.

All three are worked out on paper and in the schedule before a crew is booked.

Volcano did a master bath remodel for us. The project was completed efficiently and on time. All of their workman were courteous and hard working. When we had a couple of material delivery delays they kindly adjusted their schedules. Their pricing was fine and the terms of the contract were fulfilled. We highly recommend Volcano Building.

I recently hired Bar from Volcano Builders to remodel my bathroom. Overall, the experience was satisfactory. Bar was professional and communicated well throughout the project. The work was completed on time and within budget. The quality of the remodel met my expectations, though there were a few minor details that could have been improved. I would recommend Bar for anyone looking for a reliable contractor for bathroom renovations.

Bar Unger, founder of Volcano Builders

I'm Bar, founder of Volcano Builders. I have been building for 20+ years, and our main office is in Bellevue. Most remodeling problems start before any work does: a vague price, a missed permit step, nobody answering the phone. So every project we take on gets a written, itemized price before work starts, a design and permit plan built around your city's rules, and one project manager you can actually reach.

    One project manager runs the build through the final walkthrough.

Guide

Remodeling in Yelm: permits, prairie habitat, creeks and ADUs

How a building permit works in Yelm

Permits come from the Planning and Building Division of Yelm Public Services, whose staff work weekdays from 7 a.m. to 5 p.m. The building permit application is an online form on the city's forms site: it asks for the Thurston County parcel number, the project type (remodel, addition, plumbing or mechanical work among them) and the plans, uploaded as PDF, TIF or image files. The city's residential application also asks every contractor for a state registration card and a current City of Yelm business license.

Construction permits are ministerial in Yelm, which means clear, objective standards and no public notice or hearing. Plans are reviewed under the International Building and Residential Codes as amended by the state, and the city's adoption includes the appendix for tiny homes. Electrical permits and inspections come from the Washington State Department of Labor and Industries rather than the city.

The plan review fee is set at 65 percent of the building permit fee, and building values come from the International Code Council's valuation tables. A permit expires if work has not begun within 180 days of issue or stops for 180 days. The city publishes no review times, so the start date is set once the permit is in hand.

Creeks, flood maps and the drinking water below

Yelm Creek, Thompson Creek, the Centralia Canal, McKenzie Lake in Cochrane Park and Stolberg Lake all lie in or next to the city, and the Nisqually River runs just outside it from the southwest around to the northwest. The city's climate vulnerability assessment notes that FEMA maps put parts of Bald Hill Road, First Avenue, Stevens Street and Crystal Springs Street NE inside 100-year flood zones and regulatory floodways. The state Department of Ecology lists no Yelm shoreline master program, so the creeks are handled through the critical areas code.

Where a lot touches a special flood hazard area, the application records the lowest floor elevation on an elevation certificate. On the rare slope steep enough to count as a landslide hazard, the code keeps a buffer at least as wide as the slope is tall and limits clearing to May 1 through October 1.

All of Yelm's drinking water comes from three city wells drawing on aquifers between 61 and 633 feet deep, and the city's stormwater system relies on its high infiltration soils, with ponds and catchment basins spread across town. The code asks all new development, redevelopment and small parcel development to meet the water quality requirements of the city's stormwater manual, so runoff from a new roof or driveway is part of the plan.

Prairie habitat and the gopher review

Yelm grew up on a glacial prairie in the shadow of Mount Rainier, and the city describes the South Puget Sound prairie as a rare and declining natural community. The Mazama pocket gopher lives in those soils, which is why the city screens projects on mapped gopher soils. Even the local Yelm fine sandy loam is on the protocol's list of soils the gopher uses.

City staff or a qualified consultant trained by the US Fish and Wildlife Service walk the parcel for mounds, and a negative finding stays valid for the life of the underlying city permit. Foundation repair and heating oil tank removal are among the jobs the protocol releases from screening.

Accessory dwelling units in Yelm

Yelm's low-density residential zone lists secondary dwelling units as a permitted use and allows one on a single-family lot. The unit, whether a conversion or an addition, may reach 1,000 square feet on a lot under one acre and 1,500 square feet on a lot of an acre or more.

To help owners start, the city offers a library of pre-approved ADU building plans for lots inside the city limits. An owner picks a design and sends in the application, and city staff then check it against that lot's setbacks, utilities and shape.

State law, Engrossed House Bill 1337, requires cities to allow at least two ADUs on lots in an urban growth area and a size limit no smaller than 1,000 square feet, and it overrides conflicting local rules. We confirm with the Planning and Building Division which limit applies to your lot before design.

Yelm houses by the numbers

Yelm is a young city in housing terms. The Census Bureau's 2020 to 2024 American Community Survey puts the median home at 2004, with about six in ten built since 2000 and the 2000s alone accounting for roughly a third. About three in four homes are detached houses, and about two in three occupied homes are lived in by their owners. Older houses are a minority: roughly one in seven predates 1980.

In a house built in the early 2000s, original kitchens, bathrooms, flooring and fixtures are the usual things to replace. The older ones can hold original wiring and plumbing behind the walls. Either way, the written price lists what we expect to find before work starts.

Questions

Yelm remodeling questions

How do I apply for a building permit in Yelm?

Through the City of Yelm's online Building Permit Application, which takes the parcel number, the project type and the plans as uploaded files. The Planning and Building Division reviews it, and electrical work goes separately to the state Department of Labor and Industries. On our projects we prepare the drawings and submit both.

Will my Yelm remodel need a pocket gopher survey?

Only some projects do. The city screens applications on soils mapped as gopher habitat, and work inside the footprint of an existing house, foundation repair, or a project more than 300 feet from those soils can be released. When a survey is needed, the visits count only from June 1 to October 31.

Can I build an ADU on my Yelm lot?

Yelm zoning allows a secondary dwelling unit on a single-family lot, up to 1,000 square feet on lots under an acre, and the city offers pre-approved ADU plans with a site review. State law asks cities to allow two units, so we confirm the limit that applies with the city first.

My property is near Yelm Creek. What changes?

More review before an addition or deck. The critical areas code sets a 150 foot riparian habitat area along Yelm Creek and Thompson Creek, and parts of town sit in FEMA flood zones or county high groundwater areas, where the lowest floor and setbacks from the hazard edge are controlled.

What will a remodel in Yelm cost?

That depends on the scope and on what the house shows once it is opened: moving plumbing, walls or a STEP tank line costs more than updating a room in place. You receive a written, itemized price before work starts, and typical ranges by project type are in our Remodeling Pricing Guide.
