Edition: Weekly Update – March Housing Data Release, Tariff Cost Persistence, and AB 2166 Momentum (Covering Past 7 Days: approx. April 23–30, 2026)
This week’s scan is dominated by the April 29 release of March 2026 national housing starts and permits data (catch-up after prior delays), ongoing tariff effects on input prices, and continued legislative movement on factory-built housing via AB 2166. No major new California-specific statewide permit aggregates dropped, but broader trends and local analyses provide directional signals for bidding and budgeting.
Building Permits & Construction Starts (Past 7 Days)
- National March 2026 data (released April 29): Housing starts rose 10.8% month-over-month to 1.502 million (SAAR), with single-family starts up 9.7% to 1.032 million (13-month high) and multifamily also gaining. However, building permits plunged 10.8% to 1.372 million (SAAR), with single-family permits down and multifamily permits dropping sharply. This suggests near-term construction momentum but weaker forward-looking activity.
- California context: The state ranked No. 3 nationally in total housing permits issued over the 2016–2025 period (1.1 million units), behind Texas and Florida. January 2026 private housing units authorized remained around 9,598 (SAAR). Wildfire recovery areas continue with faster local permitting; broader jurisdictional delays persist.
Financial Decision Implications: Stronger March starts signal some resilience in single-family activity, but the sharp permits drop warns of potential Q2/Q3 softening. Prioritize segments with momentum (multifamily recovery, infrastructure) and prepare for variability. Monitor May releases for April data.
Material Cost Increases/Decreases (Past 7 Days & Recent Trends)
- Tariff pressures on steel, aluminum, copper, and related inputs remain elevated, with nonresidential construction input prices showing strong annualized gains early in 2026. Recent estimates (as of early April) project current tariff rates adding ~6% to materials costs vs. 2024 baseline (down from peak summer 2025 estimates of 9%), translating to ~3% total project cost increases. Copper products +25% YoY, steel mill products +21% in recent snapshots.
- Forecasts for 2026 overall material inflation remain in the 2–4%+ range, with tariffs and supply chain factors as key variables. Some seasonal lumber softening noted earlier, but volatility persists.
Trends from Previous 2–3 Months: Materials costs have stayed elevated due to tariffs (metals most impacted), with no significant relief in the past weeks. Annualized input price surges (e.g., 7–12%+ in nonresidential segments earlier) have prompted more firms to pass costs through (nearly half in some surveys), raise bids, or seek alternatives. Escalation clauses and hedging are standard practice.
Labor Increases/Decreases & Shortages (Past 7 Days & Recent Trends)
- Structural shortages continue as a top concern, with national needs in the 349,000–500,000 range for 2026 and California facing a disproportionate share. AGC surveys highlight rising direct labor costs (wages, benefits, taxes) cited by ~50% of respondents as a major issue, alongside supply constraints.
- No new weekly wage statistics, but immigration enforcement, retirements, and demand in growth sectors sustain upward pressure.
Trends from Previous 2–3 Months: Labor has consistently outpaced materials as a cost driver for many firms, leading to project delays and 4–8%+ escalation needs. While overall hiring demand has moderated somewhat, gaps remain acute, driving retention investments, training, and productivity tools. Surveys show two-thirds of California contractors flagging skilled labor as a challenge.
Other Key Information for Financial Decisions
- AB 2166 Update: The bill proposing state-backed credit backstops via the California Housing Finance Agency for factory-built (offsite) housing advanced in committee (amended and re-referred to Appropriations on April 22–23). It aims to reduce risk for developers and lenders, potentially cutting costs 20–25% and timelines significantly. Hearings and debate continue, with some criticism over taxpayer exposure versus benefits for wildfire recovery and affordability.
- Regulatory/Other: 2026 laws (e.g., 5% private retention cap under SB 61, Title 24 updates, AB 253/AB 1308 permitting reforms) continue implementation, improving cash flow and plan review timelines while adding compliance layers. AGC surveys show ~62% of contractors expecting growth/moderate activity increases, strongest in infrastructure, data centers, and power, with tariffs, labor, and costs as top headwinds.
Overall Trends (Previous 2–3 Months): Residential activity shows mixed signals—national starts rebounding in March after softer starts to the year, with California maintaining strong longer-term permit rankings but facing jurisdictional hurdles. Multifamily has been relatively resilient. Material costs remain tariff-driven and elevated (metals leading), while labor shortages drive faster wage growth and capacity issues. New laws and factory-built pushes (AB 2166 progress) offer potential efficiency gains and cash-flow improvements. Nonresidential/infrastructure segments appear more stable. For your company: Build wider contingencies for tariffs/labor (often 4–8%+); leverage retention cap benefits on new private work; assess modular/offsite opportunities amid AB 2166 developments; target resilient sectors; and use the recent starts/permits data for Q2 pipeline adjustments. Watch May housing releases and AB 2166 next steps.
