US Housing Starts and Building Permits: Single-Family Still Moving Sideways

核心结论

April data confirm residential construction remains in a grinding sideways pattern. Single-family starts (930k) are stuck inside a two‑year range (~830–1020k), and the 5.8% m/m rise in total building permits is entirely a volatile multifamily bounce. Permits do not signal a start pickup. With units under construction still elevated, real residential investment is tracking just 1.0% q/q saar in 2Q—well below any implied recovery.

证据链

Single-family starts show no breakout. April’s 9.0% m/m decline followed a strong March (+10.7%), leaving the average inside the 2024–2025 range. Year‑on‑year, single-family starts fell 2.4%. The South, which accounts for nearly half of national starts, dropped 11% m/m. Investment implication: without a sustained decline in mortgage rates, the range is likely to persist, capping upside for homebuilder equities and residential commodities.

Building permits are a misleading signal. Headline permits rose 5.8%, but single-family permits fell 2.6%. Multifamily permits (+21.8%) only reversed a 23.4% plunge in March—a noise event. The report explicitly notes to “take less signal from the gain.” Moreover, units authorized but not started remain elevated at 254k, reflecting supply‑side frictions (labor, materials, financing). Investment implication: extrapolating the headline permit gain into a start recovery is a mistake. Focus on the drifting‑lower single‑family permit trend instead.

The construction pipeline favours completions, not new starts. Units under construction (1,275k) are still near pre‑GFC highs despite declining from the pandemic peak. Single‑family under construction have fallen for six consecutive months, and single‑family completions also declined for the sixth month. This suggests builders are working through backlog rather than accelerating new activity. Investment implication: run‑off of under‑construction units will add supply, pressuring home prices and margins, but does not represent fresh GDP contribution from new starts.

关键分歧与风险

• Higher‑for‑longer mortgage rates could push single‑family starts below the current range floor, especially if builder confidence (NAHB index) slips again.
• Persistent supply constraints (labour shortages, rising material costs) may prevent “authorized but not started” units from converting to actual starts.
• Multifamily volatility risks misinterpretation: one strong month does not signal a structural upturn, yet it could lead to over‑optimistic positioning in REITs or related sectors.

估值或交易含义

Maintain a cautious stance on residential construction exposure. Avoid chasing multifamily‑related equities or high‑beta homebuilder names on headline permit strength. The 1.0% 2Q residential investment forecast implies negligible GDP contribution, reinforcing that housing will not offset other macro headwinds. Key leading indicators: 30‑year mortgage rate trajectory and NAHB Housing Market Index. Only a sustained rate decline or a material easing of supply constraints would justify a constructive re‑rating of the sector.
