Aloha, Oregon, is an unincorporated census-designated place in Washington County with a 2020 census population of 53,828 residents and an estimated 2026 population of approximately 54,271, making it the largest unincorporated community in Oregon by population. Located approximately 11 miles west of downtown Portland along Tualatin Valley Highway (TV Highway), Aloha has no municipal government and falls entirely under Washington County permit jurisdiction. The community was named in 1912, though the name is pronounced locally as ‘A-LOW-wa’ rather than the Hawaiian ‘A-LOH-ha.’ Pacific Building Solutions holds Oregon Contractor License #215897 and serves the Aloha multi-family and commercial property market within our established Washington County coverage area, adjacent to Beaverton and Hillsboro.

Aloha’s median construction year of 1984 makes it one of the most concentrated LP siding markets in the Portland Metro region. The vast majority of the community’s multi-family and residential stock was built between the mid-1970s and the late 1990s, falling squarely within the documented installation window for LP Outer-Seal siding, the wood composite product that was the dominant low-cost cladding choice in Pacific Northwest construction during those decades. LP siding is a documented failure product that absorbs moisture, swells at joint lines, and deteriorates from the inside out. Multi-family properties in Aloha with original LP siding still in place are carrying a known-failure product at or beyond its expected service life.

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.

• Concentrated LP Siding Era: With a median construction year of 1984 and most of the housing stock built between 1975 and 1998, Aloha’s multi-family inventory is heavily concentrated in the LP Outer-Seal siding installation window. Properties that have not undergone siding replacement are almost certainly carrying LP siding. Our assessments confirm product type, document failure extent, and scope of the replacement program.
• Washington County Unincorporated Permitting: Aloha has no municipal government. All permits and inspections fall under Washington County jurisdiction. Our project teams handle county-level permit coordination in unincorporated communities as standard project management, without the delays that affect contractors unfamiliar with unincorporated county oversight.
• TV Highway Corridor Coverage: Aloha’s multi-family and commercial inventory is concentrated along Tualatin Valley Highway and the surrounding corridors. Our project management teams access the area efficiently from our Portland Metro base, and our established presence in neighboring Beaverton and Hillsboro makes Aloha a natural extension of our Washington County coverage.
• Oregon State Licensing: We hold Oregon Contractor License #215897 as our primary license for all work in Aloha and Washington County. We also hold Washington License #PACIFBS831MK for ownership groups managing cross-state portfolios.

LP Siding Replacement and Multi-Family Siding Programs

LP Outer-Seal siding replacement is the primary remediation scope for Aloha’s multi-family inventory. Full LP removal, substrate assessment and repair, weather barrier restoration, and replacement with James Hardie fiber cement, Cedar, or Craneboard systems. LP removal consistently reveals failed window systems and flashing deficiencies, which we address during the same mobilization.

Exterior Envelope Remediation

Full building envelope assessment and remediation for multi-family and commercial properties throughout Aloha. Our assessments are calibrated to the 1970s-1990s Pacific Northwest construction profile that defines Aloha’s housing stock, identifying the specific failure patterns common in LP siding buildings of this era.

Water Intrusion Repair and System Restoration

LP siding failure and inadequate weather barriers are the primary drivers of water intrusion in Aloha’s older multi-family stock. We trace the system-level cause, restore the building envelope, and document every phase for HOA boards, property managers, and legal oversight teams.

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. LP siding installation during the 1990s is a documented context for construction defects in Oregon. We work alongside construction attorneys, owner representatives, and forensic consultants throughout Aloha and Washington County.

Window System Replacement

LP siding removal in Aloha’s 1980s and 1990s buildings reliably reveals failed window systems at rough openings. We replace window systems in occupied multi-family buildings using Andersen, Jeld-Wen, Marvin, Cascade, Milgard, and triple-pane systems, coordinating window replacement with siding programs for a complete envelope solution in a single mobilization.

Mold Remediation and Structural Repair

LP siding failures and sustained water intrusion in Aloha’s older multi-family stock frequently lead to secondary mold growth and structural compromise. We integrate mold remediation and structural repair into our siding replacement scopes rather than leaving those elements to separate contractors.

Does Pacific Building Solutions serve Aloha, Oregon?

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

How do I know if my Aloha multi-family property has LP siding?

Aloha’s median construction year of 1984 places most of the community’s multi-family inventory squarely within the LP Outer-Seal siding installation window. LP siding is a wood-composite panel product that typically shows early failure at the bottom panel edges, horizontal joints, and around window and door openings. Signs include swelling, soft spots on probing, deterioration along joint lines, and paint failure that recurs after repainting. A full envelope assessment will confirm product type, document the extent of failure, and scope the replacement program.

How does Aloha’s unincorporated status affect building permits for envelope remediation?

Because Aloha has no municipal government, all building permits and inspections fall under the jurisdiction of Washington County. Our project teams handle county-level permit coordination as standard project management. This does not create delays or complications on our projects.

Can Pacific Building Solutions work alongside construction attorneys on LP siding claims in Aloha?

Yes. LP siding installation during the 1990s is a documented construction defect context in Oregon, and working alongside construction attorneys and forensic consultants on LP-related remediation programs is a standard part of our practice. We provide the documentation, scope discipline, and field reporting that those environments require.

Is Pacific Building Solutions licensed to work in Aloha and Washington County, Oregon?

Yes. We hold Oregon Contractor License #215897, which covers the entire state of Oregon, including unincorporated communities in Washington County, such as Aloha. We also hold a Washington Contractor License #PACIFBS831MK. Both are active and current.

Aloha is an unincorporated census-designated place in Washington County, Oregon, located approximately 11 miles west of downtown Portland along Tualatin Valley Highway. The community was named in 1912, with local tradition holding that Robert Caples, a railroad worker, named the post office after the Hawaiian greeting, though the community has always pronounced the name ‘A-LOW-wa’ rather than the Hawaiian ‘A-LOH-ha.’ With a 2020 census population of 53,828, Aloha is the largest unincorporated community in Oregon by population, larger than most of the state’s incorporated cities.

Aloha has never been incorporated as a city and falls entirely under the Washington County government for permitting, zoning, and public services. The community’s development occurred primarily during the second half of the 20th century, with the median construction year of 1984 reflecting the concentrated 1970s-1990s suburban expansion that produced the community’s current housing inventory. Aloha is bordered by Beaverton to the east, Hillsboro to the west, and unincorporated Washington County communities to the north and south, and is served by TriMet bus routes along Tualatin Valley Highway.

If you represent an HOA board, multi-family property management group, construction attorney, building envelope consultant, or commercial ownership group with a property in Aloha or Washington County, Pacific Building Solutions welcomes the opportunity to discuss your project.
