Housing and zoning
Supply, permitting, tenant protection, and who decides what gets built.
Briefing
What this room is about
Housing costs a large share of income for many renter households, and supporters of more building argue that this is because too few are built where jobs are. The argument here is less about whether to build and more about where, how fast, who decides, and who carries the disruption.
Source for the opening clause (US, data year 2023): in 2023, 49.7% of the 42.5 million US renter households for whom rent burden is calculated spent more than 30% of their income on housing costs (Census, 2023 American Community Survey 1-year estimates, press release of Sept. 12, 2024).
High housing costs are not only a US issue. OECD data (mostly 2022; US 2021) show that in eight countries, including the United States, Spain, Sweden and Switzerland, median housing costs exceed 40% of income for low-income renters. In many Central and Eastern European countries, fewer than 20% of low-income private renters spend that much (OECD Affordable Housing Database, HC1.2). We have not yet written a global comparison of zoning systems.
Strongest case for action
Supporters argue that rules that ban anything but detached houses on most residential land keep supply short and push prices up. They argue that allowing duplexes, townhouses and apartments near transit is one of the few levers that lowers rents over time.
Supporters of social and subsidized housing point to the OECD data. In almost all countries, people in subsidized rentals are less likely to be overburdened by housing costs than private renters, often by a wide margin. In Israel, for example, the figures are 2% and 54% (OECD HC1.2).

Strongest case for caution
Those urging caution argue that new building can arrive faster than schools, sewers and transit can absorb it, and that early projects often land in lower-income areas first. Upzoning without affordability or tenant protections can raise land values before it lowers rents.
Cross-country comparisons are rough. The OECD uses gross rather than disposable income for the US, and country data years range from 2017 to 2022 (OECD HC1.2). Borrowing costs are also shifting: in June 2026 the OECD reported that mortgage costs in the US and Europe "have increased markedly" as bond yields rose (OECD Economic Outlook).

What locally changes the answer
Vacancy rate, how much land is already zoned for more than one home, whether infrastructure has spare capacity, and how many residents rent rather than own.
For comparisons, use the OECD Affordable Housing Database, which covers housing costs, social housing, rental regulation and housing allowances by country (OECD). Then check the country's national statistics office. Things to compare: how much housing is social or subsidized, the mix of renters and owners, whether mortgages are mostly fixed or variable rate, and whether zoning is set nationally, regionally or locally.

Notes at global scope
- ▸Housing costs have outpaced incomes in most large cities worldwide since 2010.
- ▸Places that built steadily (Tokyo, parts of Texas) saw slower rent growth.
- ▸Social housing models differ widely: Vienna and Singapore are the usual references.
