Light signal day — a single data point from Potter, but it cuts to the heart of why US construction costs remain structurally elevated.

[CONSTRUCTION COSTS: The Regulatory Weight Nobody Measures]

Brian Potter's reading list surfaces a UCLA Lewis Center paper that deserves attention from anyone trying to understand why American housing is so expensive to build. The core finding: building code provisions are routinely added with no formal cost-benefit analysis — and the compounding effect over decades is substantial.

The paper's sharpest example: a stretcher-size elevator mandate proposed by an Arizona fire marshal roughly 20 years ago. The reported cost impact at adoption? "None." The actual cost impact today? A basic 4-stop elevator runs ~$158,000 in New York City versus ~$36,000 in Switzerland — a 4.4x price premium traceable in part to that single uncosted provision.

The downstream consequence matters as much as the number itself. That cost burden is a direct driver of the prevalence of 5- and 6-story walk-up construction in US cities — buildings that sidestep elevator requirements entirely, but in doing so produce units inaccessible to elderly and disabled residents. Potter notes this design is "unheard of in most" comparable countries.

This is the structural affordability problem in miniature: individual code provisions, each defensible in isolation, accumulate into a regulatory load that inflates per-unit costs, shapes building typology, and ultimately restricts supply. The Strait of Hormuz dominates Potter's reading list this week for good reason, but this housing item is the durable signal.

TL;DR - Building code costs are largely untracked at adoption — a UCLA paper finds provisions routinely pass without cost-benefit analysis, with elevator mandates a vivid case study - US elevator costs run ~4x Swiss equivalents (~$158K vs. ~$36K for a basic 4-stop), a concrete example of how regulatory layering inflates construction costs - The affordability loop closes through building typology: high elevator costs push developers toward walk-up construction, reducing accessibility and constraining unit mix - No rate, inventory, or demand signal today — thin content cycle
