Why Fair Market Rents Vary So Much Between Cities

If you look at FMR data across the country, the range is striking: a 2-bedroom unit in San Francisco has an FMR of $3,135, while the same bedroom size in rural West Virginia has an FMR of $660. That's nearly a 5x difference — and both numbers represent "modest" housing in their respective markets.

Labor Markets Drive Housing Costs

The single biggest driver of rent variation across US metros is the strength of the local economy, particularly wages and employment. High-wage cities attract workers; more workers competing for housing means higher rents. San Francisco, New York, Seattle, and Washington DC all have high FMRs because they have concentrated, high-paying industries.

Geographic Constraints

In coastal cities, you often can't just build outward — land is surrounded by water or mountains. San Francisco is famously constrained by peninsulas and hills. This physical scarcity amplifies the price effects of high demand. Cities with more buildable land — like Phoenix or Dallas — tend to have somewhat lower rents even with significant population growth.

Zoning and Land Use Restrictions

Even where land is available, local zoning laws can severely restrict new housing construction. Single-family zoning in desirable areas limits supply, driving up prices for existing units. Studies consistently show that cities with more permissive zoning have lower rents relative to income levels.
