Mold Removal in Tualatin and Sherwood, OR: Homes Built Since the 1990s

Two cities built since the 1990s, with different housing mixes

The American Community Survey (2020 to 2024) counts 11,303 housing units in Tualatin, with a median build year of 1992, and 7,055 in Sherwood, with a median of 1997. Tualatin built 3,393 homes in the 1990s and another 2,782 in 2000 or later, and only 396 predate 1970. Sherwood built 2,710 in the 1990s, 38 percent of its homes and the largest share of any city we serve, and 2,832 in 2000 or later. The census counted 3,093 residents in Sherwood in 1990 and 11,791 in 2000.

The two cities differ in who lives in the housing. Nearly 45 percent of Tualatin households rent, and 30 percent of its homes, about 3,400, are in buildings with five or more units. In Sherwood, 72 percent of households own their home, 72 percent of homes are detached houses, and only 14 percent are in buildings with five or more units.

Tualatin: condominiums, apartments, and shared walls

Tualatin Commons, a three-acre man-made lake, was established in 1994 as a downtown redevelopment. Buildings with five or more units, which hold three in ten Tualatin homes, put several households under one roof structure and on shared plumbing, so a leak in one unit can reach another. Responsibility depends on where the water began and on the association's governing documents.

Dated photos, written notice, and moisture readings taken before drying begins help everyone involved. Owners and managers can read about our property manager and landlord services, and renters can find the landlord's duty under ORS 90.320 summarized on our Beaverton page.

Sherwood: homes in their second and third decades

A house finished in the late 1990s has outlived Oregon's ten-year limit on residential construction claims (ORS 12.135), so claims against the builder are generally out of time and the questions are about maintenance. Roofing, exterior caulk, and window seals installed three decades ago commonly need attention at this age, and a small failure at any of them lets water into a wall for months before it shows. A moisture-focused inspection looks at those points before it looks at any visible growth.

The Brookman Road area, about 235 acres of rolling hills, floodplains, and secondary forest, was brought into the urban growth boundary in 2002 and planned in a concept plan the city adopted in June 2009. Until a piece of it is annexed, it remains unincorporated Washington County. A house in the area completed within the last ten years may still be inside ORS 12.135's window.

The Tualatin River in February 1996

The Tualatin River flows along most of Tualatin's northern boundary. In February 1996, after a January snow and ice episode, heavy rain on saturated ground pushed the river at Farmington, upstream, to 37.2 feet, above the previous record of 37.0 feet set in 1933 and well over the 32-foot flood stage, according to the Oregon Climate Service. A hydrologist with the Oregon Department of Forestry rated the river's floods at two gauges as equivalent to events of 75 years or more in a preliminary review.

FEMA's flood maps show which parcels are in the mapped floodplain, and a property's flood zone affects insurance options. Standard homeowners policies differ on water coverage, so the policy itself is the place to check. After any flooding, the EPA advises drying water-damaged areas within 24 to 48 hours.

How the work is planned for Tualatin & Sherwood homes

In Tualatin, 45 percent of households rent and 30 percent of homes share a building with five or more units. In Sherwood, 72 percent of households own a detached house, and 79 percent of homes were built in 1990 or later. Scopes are written for either: shared-wall documentation in the first case, and an inspection that starts with the building envelope in the second.
