Mass timber is great, but it will not solve the housing shortage

Mass timber vs. other construction

• Many note mass timber is intended to replace steel/concrete mid‑ and high‑rise, not stick‑built single‑family homes.
• It uses more wood volume than light framing; some see this as acceptable for taller buildings with long spans, stiffness, and aesthetic appeal, others see it as wasteful and expensive.
• Several argue the real comparison is cost and performance against reinforced concrete, not studs and trusses; evidence from specific projects is mixed and context‑dependent.
• For low‑rise housing, most agree mass timber won’t be cost‑competitive soon and thus can’t “solve” the shortage.

Root causes of the housing shortage

• Broad consensus: the shortage is mostly political and regulatory, not technological.
• Repeated themes: restrictive zoning (especially single‑family only), lengthy and subjective permitting, NIMBY lawsuits, parking minimums, and infrastructure constraints.
• Some emphasize under‑building relative to population growth; others stress maldistribution (jobs and people clustered in a few metros while other areas have excess housing).
• There is disagreement about how much vacant units, corporate ownership, Airbnbs, and immigration contribute; some call them major drivers, others say data shows their impact is secondary to zoning/supply.

Density, urban form, and lifestyle

• Strong current arguing for more “missing middle” housing (3–5 story walkable, mixed use) rather than only SFH or towers.
• Many describe US suburbia as space‑ and infrastructure‑inefficient and implicitly subsidized, though some dispute the subsidy evidence.
• Others insist most Americans still prefer detached homes and privacy; they see apartments as noisy, fragile, and socially risky.
• Post‑Soviet, European, and Asian cities are cited as counterexamples where dense multifamily is normal and walkable, but critics point to differing culture, climate, and transit quality.

Construction costs and industry realities

• Multiple practitioners say materials are only part of the cost; land, labor, permits, and code requirements dominate.
• Construction is conservative because failures are catastrophic and warranties long; innovation is slow and path‑dependent.
• Examples of costly requirements: insulation standards, seismic/fire codes, road/utility upgrades, asbestos abatement, impact fees.

Environment and materials

• Debate over timber as a carbon sink vs. current unsustainable forestry and pellet use.
• Concrete’s CO₂ emissions are acknowledged; some note longevity and innovations (e.g., alternative reinforcement, “self‑healing” mixes).

Policy ideas (contested)

• Proposals include: zoning reform/upzoning, taxing vacant or non‑primary homes, limiting corporate ownership, land value tax, promoting ADUs and SROs, better transit, and reusing offices.
• Strong disagreement on punitive landlord/vacancy taxes, rent control, and extreme anti‑investor measures; many warn they’d backfire or be politically impossible.
