Portland closed out the year with stories that captured the city’s ongoing effort to expand housing thoughtfully—balancing historic preservation against current demand, adaptive reuse of industrial landmarks, and incremental regulatory changes to enable more homes. From supportive towers built with sustainable mass timber to statewide zoning tools re-legalizing neighborhood apartments, and creative transformations of obsolete sites, the week reflected a market navigating caution while pursuing infill and affordability in established areas.

Downtown Portland marked a milestone with the opening of Julia West House, a 12-story mass timber tower providing permanent supportive housing for seniors who had experienced homelessness. Built on a former parking lot at 580 SW 13th Avenue, the project delivers 90 units—60 studios and 30 one-bedrooms, with 89 deeply affordable at 30% or less of area median income, plus one unrestricted manager unit. On-site services from partners like Northwest Pilot Project focus on aging in place, addressing the reality that nearly a quarter of the city’s unhoused population is age 55 or older.

As Oregon’s tallest mass timber residential building at 145 feet, it employs cross-laminated timber floors and glulam beams above a concrete podium, shortening the construction schedule by about 14 weeks and incorporating biophilic elements like exposed wood ceilings. Adjacent to another supportive building, it forms a concentrated hub in the West End.

Developments like this expand deeply affordable rental supply in central locations with strong transit access. They provide market evidence of efforts to address affordability and homelessness, informing highest and best use considerations for nearby properties and enhancing neighborhood marketability.

In multifamily assignments, mass timber construction sets emerging precedents for sustainable practices, potentially affecting future replacement costs, capitalization rates, and development feasibility in urban zones. Restricted units supported by tax credits require careful isolation of encumbered interests from hypothetical fee simple value.

Monday, December 15: Fannie Mae Expands ADU and Renovation Eligibility

Fannie Mae updated its guidelines with significant expansions to renovation lending and accessory dwelling unit eligibility, offering more options for homeowners in the Portland region. HomeStyle Renovation loans now allow upfront disbursements of up to 50% of renovation costs at closing, while removing prior caps on manufactured home improvements—now up to 50% of as-completed value.

Effective in 2026, single-unit properties can include up to three ADUs if zoning permits, with total units capped at four even on two- to three-unit homes. These changes align manufactured housing more closely with site-built and build on local incentives like temporary system development charge waivers.

The updates heighten reliance on as-completed valuations for loan-to-value ratios and eligibility. Appraisers may see increased demand for projected-value analyses on properties with multiple ADUs or extensive renovations, requiring solid review of local zoning and market acceptance to support highest and best use conclusions.

These provisions complement Portland metro efforts to encourage middle housing, providing alternatives to jumbo financing alongside rising FHA limits.

Tuesday, December 16: Oregon Model Code Enables Neighborhood-Scale Apartments

Oregon adopted a statewide model zoning code under the Oregon Housing Needs Analysis framework, shifting from unit caps to form-based standards that re-legalize small apartment buildings in residential zones. The rules permit duplexes through fourplexes, townhouses, and cottage clusters outright, with bonuses for accessibility or affordability, while slashing parking mandates.

Affected cities—primarily Oregon’s larger municipalities, including Portland, Beaverton, Gresham, Hillsboro, and others in the metro area—must align zoning with the model code if they fail to meet production targets, though implementation timelines vary by jurisdiction and can extend several years. Form-based limits keep development neighborhood-scale, typically supporting 6–12 units on a standard lot.

These rules expand as-of-right development options on residential lots, particularly corner or larger parcels in single-family zones. Highest-and-best-use analyses may now reflect stronger redevelopment potential for small multifamily or middle housing types in cities subject to the model code.

Although the model code removes unit-count caps, form-based limits on height, coverage, and floor area ratio maintain neighborhood character. While larger projects, such as a 16-unit building, are now more feasible, they remain a different undertaking involving complex regulatory review, commercial-grade construction, specialized financing, and contractor expertise.

Market activity will likely continue to favor rehabilitation of existing homes alongside gradual small-scale infill—many builders focus on single-family with ADUs. Appraisers need to be mindful of what is possible under the new zoning allowances while analyzing what the market is actually doing.

Form-based standards and reduced parking mandates lower barriers to small apartment or townhouse projects, with affordability bonuses providing quantifiable incentives. Over time, this may broaden comparable selection for emerging middle housing.

Wednesday, December 17: Reviving Portland Development: Design Review Reforms, Bureau Cuts, and the Push for More Housing

New construction slowed markedly in the Portland region, with Q3 2025 single-family sales dropping 25% year-over-year and comprising just 9% of transactions—steeper in Multnomah County at roughly 48%. Reduced activity contributed to monthly shortfalls at the Bureau of Development Services, leading to 72 staff cuts.

City Council advanced studies on design review exemptions and moratoriums for housing, alongside the Unified Housing Strategy’s focus on streamlining, consolidated processes, and incentives like extended state tax exemptions for mixed-use.

Short-term staffing reductions may prolong timelines, impacting feasibility in proposed construction assignments.

Longer-term reforms could boost multifamily supply, expanding comparables for vertical mixed-use or conversions—though gains may lag into 2026–2027 amid ongoing caution.

Thursday, December 18: Portland’s Historic Homes and the PSU Demolition Debate

Portland State University’s plan to demolish two early-20th-century residence halls on the Historic Resources Inventory for new student housing spotlighted preservation challenges. The buildings lack full landmark status, limiting delays, yet advocates highlight rehabilitation benefits for carbon and culture.

In the private market, only 15 verified registered historic single-family sales occurred in Portland from 2023 through Q3 2025, averaging $1,256,588 in premier neighborhoods like Irvington. These reflect premiums for authenticity offset by maintenance and review burdens, with incentives available.

Due diligence via Portland Maps or title reports is essential to confirm designation—many older homes lack it.

Designations influence marketability through higher costs and restrictions, balanced by tax benefits for qualifying owners.

Friday, December 19: 1803 Fund Unveils Adaptive Reuse Plans for Portland’s Historic Grain

The 1803 Fund detailed plans to preserve Portland’s 1914 grain silos on the Willamette east bank as a cultural waterfront hub with galleries, event spaces, and mixed-use additions. The $70 million acquisition covers the three-acre silo site plus about 20 tax lots in The Low End (seven acres), totaling roughly 10 acres.

The silo site’s history illustrates functional obsolescence: after $21.5 million modernization in 2013, it sold for $164,000 in 2019 post-rail loss, then $2.9 million in 2021, with a recent $6.5 million listing. Assembly unlocked plottage for master-planned redevelopment, including multi-million remediation of brownfield contamination and a projected $700 million economic impact.

This demonstrates highest and best use shifts in industrial zones—from obsolete terminal to cultural anchor—with rezoning needed for proposed hospitality elements.

Plottage and stigma removal can lift land values in obsolescent corridors, creating uplift via public amenities.

Saturday, December 20: Alberta Alive Townhomes Rise Opposite Historic Alberta Abbey

Construction began on Alberta Alive Townhomes in Northeast Portland’s Alberta Arts District, delivering eight permanently affordable three-bedroom units via Proud Ground’s community land trust. Opposite the historic Alberta Abbey, these all-electric, Earth Advantage-targeted homes prioritize families with local ties.

Nearby market-rate three-bedroom attached homes averaged $574,900 over four years (1,650 square feet, $355 per square foot), highlighting the premium these restricted units address through public funding. Local families will be able to enjoy quality townhome units that would otherwise be unaffordable.

Community land trust units—with resale caps—are not directly comparable to unrestricted sales. Appraisers generally omit affordable housing units from analyses involving unrestricted properties.

High-quality infill can stabilize neighborhoods and anchor upward pressure on conventional properties nearby.

Julia West House Opens in Downtown Portland

The Julia West House, a 12-story mass timber apartment tower in downtown Portland’s West End, officially opened in late 2025, delivering 90 units of permanent supportive housing targeted at formerly unhoused seniors. Located at 580 SW 13th Avenue on a former surface parking lot owned by First Presbyterian Church—the site of a historic home previously used for church programs—the project provides 90 total units: 89 regulated affordable units (60 studios and 30 one-bedrooms) reserved for individuals earning 30% or less of area median income, with the remaining unit serving as an unrestricted on-site manager apartment.

The tower retains the name Julia West House in honor of Julia West Lindsley, wife of the church’s first pastor, continuing a legacy of community service at the address. Situated directly across SW 13th Avenue from the Sam Galbreath Alder House—a renovated income-restricted single-room occupancy building also offering supportive services—the location creates a concentrated hub for permanent supportive housing in the West End. This focus addresses a critical segment of need: nearly a quarter of Portland’s unhoused population is age 55 or older, with BIPOC communities disproportionately represented.

On-site wraparound services, delivered by Northwest Pilot Project, Native American Rehabilitation Association of the Northwest, and Community for Positive Aging, include case management, health support, and programs to promote aging in place and housing stability. As Oregon’s tallest mass timber residential structure at 145 feet, the building utilizes cross-laminated timber floors and glulam beams above a concrete podium, enabled by Type IV-B heavy timber provisions. This construction method reduced embodied carbon, shortened the schedule by approximately 14 weeks, and incorporates biophilic and trauma-informed design elements—such as exposed wood ceilings—for resident well-being.

Financing combined public and private sources, including 4% Low-Income Housing Tax Credits and contributions from the Portland Clean Energy Community Benefits Fund, demonstrating a viable model for deeply affordable urban infill.

Appraisal Implications

Residential Properties

Developments like Julia West House expand the supply of deeply affordable and supportive rental housing in the Portland metro area, where single-family inventory remains limited. These projects provide market evidence of ongoing efforts to address affordability and homelessness in central locations with strong transit access, informing highest and best use considerations for nearby properties and enhancing neighborhood marketability.

Multifamily Properties

Mass timber construction in high-density supportive projects sets emerging precedents for sustainable building practices, potentially affecting future replacement costs, capitalization rates, and development feasibility in urban zones. Restricted affordable units, supported by Low-Income Housing Tax Credits and similar programs, require appraisers to carefully isolate restricted interests from fee simple value. While challenges persist—as illustrated by the 1,863 vacant regulated units reported earlier this week—successful openings like Julia West House highlight effective delivery models for mission-driven housing with integrated services.

Market Context

Q3 2025 median prices for detached single-family homes stood at $600,000 regionally and $555,000 in Multnomah County, reinforcing the ongoing need for affordable alternatives beyond the for-sale market. Purpose-built supportive housing adds targeted supply that supports broader regional stability without directly competing in the single-family segment.
