Keizer, Oregon, is a city in Marion County, located immediately north of Salem along the western bank of the Willamette River, with a 2020 census population of 39,376 and an estimated 2024 population of 39,152. Keizer is known as the Iris Capital of the World for the iris farms that once defined its agricultural landscape. The city’s civic biography is distinctive: it required seven separate attempts spanning decades before residents finally voted to incorporate on November 2, 1982, when the Oregon Legislature changed the minimum population threshold to allow communities of 20,000 or more to incorporate. At the time of incorporation, Keizer became the 12th-largest city in Oregon with a population of 19,650. Pacific Building Solutions holds Oregon Contractor License #215897 and serves Keizer and the northern Salem Metro corridor.

Keizer’s incorporation in 1982 with a population of 19,650, and its rapid growth through the 1990s, produced the multi-family and HOA housing inventory that now defines the city’s residential character. Properties built in the years immediately following incorporation and through the 1990s growth period are now 25 to 40 years old, which falls within the active and deep remediation window for Pacific Northwest construction from that era. The city’s position immediately north of Salem, bounded by the Willamette River on the west and Interstate 5 on the east, creates a compact, dense residential geography where multi-family properties are closely concentrated along the River Road and Chemawa Road corridors.

We do not perform small residential repairs or new construction. Our practice is focused on large-scale commercial and multi-family envelope remediation for HOA boards, property managers, construction attorneys, and ownership groups.

• 1982-2000 Construction Era Now in Active Remediation: Keizer incorporated in 1982 and grew rapidly through the 1990s, earning it a reputation as one of the fastest-growing cities in Oregon during that decade. The multi-family and attached housing properties built during this growth wave are now 25 to 40 years old, in the active and deep remediation window for Pacific Northwest construction from those eras. LP siding, early weather barriers, and original window systems from this period are consistent findings in our assessments throughout the Keizer corridor.
• Willamette River Corridor Moisture Context: Keizer’s western boundary is the Willamette River, and the city sits at an elevation of 128 feet in the flat Willamette Valley. The river’s proximity and the valley’s documented 40 to 50 inches of annual rainfall create ambient moisture conditions that compound the vulnerability of the building envelope for older properties in the western and riverside portions of the city.
• Adjacent Salem Metro Coverage: Keizer is immediately adjacent to Salem, and our coverage of both cities allows ownership groups managing properties in both communities to work with a single contractor relationship without geographic handoffs.
• Oregon State Licensing: We hold Oregon Contractor License #215897 as our primary license for all work in Keizer and Marion County. We also hold Washington License #PACIFBS831MK for ownership groups managing cross-state portfolios.

LP Siding and Multi-Family Siding Replacement

Keizer’s 1982-2000 construction era falls within the LP Outer-Seal siding installation window. Multi-family properties in the River Road and Chemawa Road corridors that have not undergone siding replacement are likely carrying LP siding at or past its failure threshold. We execute LP replacement programs, including full substrate assessment, weather-barrier restoration, and installation of James Hardie fiber-cement or Cedar systems.

Exterior Envelope Remediation

Full building envelope assessment and remediation for multi-family and commercial properties throughout Keizer. Our assessments are calibrated to the 1982-2000 construction profile and the moisture conditions of the Willamette River corridor, identifying the failure mechanisms specific to Keizer’s primary housing era.

Water Intrusion Repair and System Restoration

Keizer’s position along the Willamette River corridor and the valley’s sustained annual rainfall create a consistent risk of water intrusion for older building envelopes throughout the city. We trace the system-level cause, restore the building envelope, and document every phase.

Construction Defect Repair and Forensic Consulting

When litigation or forensic consultant oversight applies, Pacific Building Solutions brings the documentation protocols and scope discipline required by those environments. We work alongside construction attorneys, owner representatives, and forensic consultants throughout Keizer and Marion County.

Window System Replacement

Phased window replacement in occupied multi-family buildings using Andersen, Jeld-Wen, Marvin, Cascade, Milgard, and triple-pane systems. LP siding removal in Keizer’s 1982-2000 buildings frequently reveals failed window systems, and we coordinate window replacement with siding programs for a complete envelope solution.

Exterior Capital Improvement

For Keizer HOA boards managing reserve-funded capital improvement programs, Pacific Building Solutions provides phased scheduling, documentation, and reserve study reporting across multiple construction seasons, aligned with the 1982-2000-era properties that define the city’s primary remediation inventory.

Does Pacific Building Solutions serve Keizer, Oregon?

Yes. Pacific Building Solutions serves Keizer and Marion County for commercial and multi-family exterior envelope remediation, siding replacement, water intrusion repair, and related services. We hold Oregon Contractor License #215897 and Washington Contractor License #PACIFBS831MK, and have operated throughout Oregon for nearly 30 years.

Why is Keizer’s 1982 incorporation and 1990s growth era particularly relevant to envelope remediation today?

Keizer was incorporated in 1982 with a population of 19,650 and grew rapidly through the 1990s. The multi-family and attached housing built during this growth period is now 25 to 40 years old, exactly in the active and deep remediation window for Pacific Northwest construction from those eras. LP siding, early weather barriers, and original window systems installed during the 1982-2000 period are consistent remediation findings. Keizer’s concentrated construction era means that a large share of its multi-family inventory faces the same envelope issues simultaneously.

Does Pacific Building Solutions cover both Keizer and Salem, so we can use one contractor for properties in both cities?

Yes. Keizer and Salem are adjacent communities, and our coverage of both cities allows HOA boards and ownership groups managing properties in both to work with a single licensed contractor relationship. We do not require separate contractor relationships for properties on different sides of the Keizer-Salem boundary.

How does the Willamette River affect building envelope conditions in Keizer’s riverside neighborhoods?

Keizer’s western boundary is the Willamette River, and properties along River Road and in the city’s western portions experience elevated ambient moisture levels from the river corridor. The Willamette Valley’s documented 40 to 50 inches of annual rainfall compounds those conditions. Our assessments account for each property’s proximity to the river when identifying failure mechanisms.

Is Pacific Building Solutions licensed to work in Keizer and Marion County, Oregon?

Yes. We hold Oregon Contractor License #215897, which covers the full state of Oregon, including Marion County and Keizer. We also hold a Washington Contractor License #PACIFBS831MK. Both are active and current.

Keizer is a city in Marion County, Oregon, located immediately north of Salem along the western bank of the Willamette River. The community is named after Thomas Dove Keizur, a pioneer settler who arrived via the Wagon Train of 1843 and filed a donation land claim in the area; the city’s name uses the Americanized spelling ‘Keizer’ rather than the family’s original ‘Keizur.’ Frequent Willamette River flooding hampered the area’s development for decades: in 1917, more than 70 years after the first settlement, fewer than 70 families lived in the entire Keizer area. Major floods in 1943, 1945, 1946, and 1948 reinforced developers’ reluctance to build in the low-lying floodplain.

Incorporation attempts failed repeatedly before the Oregon Legislature changed the minimum population threshold to 20,000, enabling a seventh and final attempt in 1982. On November 2, 1982, Keizer residents voted 4,440 to 3,341 to incorporate, making the new city the 12th largest in Oregon with a population of 19,650. Known as the Iris Capital of the World for the iris farms that once defined its agricultural character, Keizer grew rapidly through the 1990s. With a 2020 census population of 39,376, Keizer has doubled in size since its incorporation. The city hosts KeizerFEST, an annual community celebration featuring the Bloomin’ Iris Parade. Volcanoes Stadium in Keizer is home to the Salem-Keizer Volcanoes minor league baseball team.
