Housing Supply, Zoning and the YIMBY Fight — 2026-09-11
Housing supply debates have intensified globally this week, with French media reporting a sharp divergence between falling building permits and rising construction starts in July, while in the US, legal challenges threaten the implementation of San Francisco's new Family Zoning rules. Meanwhile, France's presidential campaign has seen housing affordability rise to the top of the political agenda as new home sales hit historic lows.

San Francisco Family Zoning faces immediate legal hurdles
Just days after San Francisco expanded its "Family Zoning" rules to allow for greater density and multi-unit structures on previously single-family lots, the city is facing dueling lawsuits. Pro-housing advocates are challenging environmental review requirements (CEQA), while opponents are suing over implementation details. This litigation highlights the friction between state-level pro-housing mandates and local enforcement mechanisms, potentially delaying the release of thousands of new units.
French construction starts rebound despite permit slump
In France, official data for July 2026 reveals a puzzling trend: while building permits (permis de construire) fell by 2.5%, actual construction starts (mises en chantier) surged by 8.9%. This divergence suggests that developers are finally breaking ground on projects approved during earlier quarters, offering a glimmer of hope for a sector that has been in deep crisis. However, industry analysts warn that the continued decline in permits signals a future slowdown if regulatory uncertainty persists.
Housing crisis dominates French presidential campaign
According to Le Figaro, the housing shortage has climbed back to the top of the political agenda in France’s presidential race. With real estate developers selling fewer units than ever before, candidates from both the right and left are proposing diametrically opposed solutions. The debate centers on whether to deregulate construction standards further or increase state intervention in land use, reflecting the global tension between market-led supply responses and state-directed planning.
Local view
In Normandy, local authorities are experimenting with "soft densification" (densification douce) to bypass traditional zoning bottlenecks. Saint-Lô Agglo is exploring policies that allow homeowners with large gardens to subdivide lots or convert existing oversized homes into multiple units. This grassroots approach aims to increase housing supply without the political backlash associated with high-rise developments, offering a model for other mid-sized European cities struggling with NIMBYism.
Context & numbers
- US Housing Completions: The US Census Bureau reported that privately-owned housing completions in July were at a seasonally adjusted annual rate of 1,212,000 units.
- French Permit Trends: Building permits in France declined by 2.5% in July 2026 compared to the previous period, marking a continued downward trend in new approvals despite the rebound in starts.
- Shortage Estimates: While specific new reports from this week are scarce, recent baseline estimates from the NAHB (Feb 2026) suggest the US needs approximately 1.2 million additional units to restore equilibrium vacancy rates, a figure likely exacerbated by current supply constraints.
On the radar
- Upcoming Census Data: The next major release of New Residential Construction data is expected in October, which will provide updated figures on building permits and starts for August 2026. Analysts will be watching to see if the US trend mirrors the French "permit decline/start rebound" pattern.
- California SB 79 Implementation: Cities across California continue to navigate the wiggle room offered by SB 79, with local governments actively seeking ways to comply with or delay the law's mandates. Legal challenges similar to those in San Francisco may emerge in other jurisdictions as enforcement mechanisms are tested.
