Mold Removal in Beaverton, OR: Apartments, Condos, and 1980s Homes

Beaverton grew from about 5,900 residents in 1960 to nearly 97,500 in 2020, and its housing shows it: 29 percent of homes were built in 2000 or later, and 38 percent are in buildings with five or more units, the largest share of any city we serve.

Built out between the 1970s and the 2000s

The American Community Survey (2020 to 2024) counts 42,771 housing units in Beaverton with a median build year of 1987. About 8,500 date to the 1970s, 6,700 to the 1990s, and 12,400 to 2000 or later, while only 18 percent were built before 1970. The census counted 5,937 residents in 1960, 31,962 in 1980, and 97,494 in 2020. Rental housing is part of that growth, and 49.5 percent of households rent.

The metro's largest share of apartments and condominiums

About 16,000 Beaverton homes, 37.8 percent, are in buildings with five or more units. In a multifamily building, one failed supply line, drain, or window seal can reach several homes, and responsibility depends on where the water started. For renters, Oregon law (ORS 90.320) requires a landlord to keep a dwelling habitable, including effective waterproofing of roof and exterior walls and any ventilation the landlord supplies. The statute does not name mold, and a local tenant legal aid office can explain how it applies to a given case.

Written notice and dated photographs help whoever ends up resolving the claim, as do moisture readings taken before anything is dried or removed. Owners and managers can read about our property manager and landlord services, and our water damage and moisture control page covers drying after a leak.

Rainfall and Fanno Creek

NOAA's 1991 to 2020 normals record 39.2 inches of precipitation a year at the Nature Park station in Beaverton, between Portland International Airport (36.9) and the volunteer stations north and south of downtown, which record 41.8 and 42.1 inches. The drier Hillsboro airport station records 35.9, so rainfall here runs a few inches above the valley-floor airports.

Fanno Creek runs through Beaverton on its way past Tigard to the Tualatin River. Clean Water Services notes that flooding is natural along the creek in the wetter months, especially in winter, and raised the Fanno Creek Trail under Scholls Ferry Road after flooding in 2022.

Beaverton, Cedar Mill, and Raleigh Hills

Cedar Mill, Cedar Hills, and Raleigh Hills are census-designated places in unincorporated Washington County rather than parts of the city of Beaverton, and we serve them along with the city. The city's own neighborhoods include Central Beaverton, Greenway, Vose, Sexton Mountain, South Beaverton, West Slope, Highland, and Five Oaks-Triple Creek. Hillsboro lies to the west.

How the work is planned for Beaverton homes

Thirty-eight percent of Beaverton homes are in buildings with five or more units and half of households rent. A scope for that kind of job records where the water began, which units and common areas it reached, and what was removed, so the owner, the manager, and any tenant can read the same record.

Mold removal in Beaverton: questions

Do you serve Cedar Mill, Cedar Hills, and Raleigh Hills?

Yes. Those areas are unincorporated Washington County rather than part of the city of Beaverton, and they are part of our service area.

A leak in the unit above mine caused mold. What should I do first?

Report it to the landlord or association in writing, take dated photos, and keep any affected materials as they are until moisture readings are recorded. The EPA advises drying water-damaged areas within 24 to 48 hours, so the report should go out quickly. Our property manager page explains the documentation involved, and a tenant legal aid office can advise on rights under ORS 90.320.

How much rain does Beaverton get?

NOAA's 1991 to 2020 normals record 39.2 inches a year at the Nature Park station, and 41.8 and 42.1 inches at two nearby volunteer stations. That is more than Portland International Airport (36.9) or the Hillsboro airport (35.9).
