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).
Zoning codes are local, written under state enabling laws (GovInfo, ROAD to Housing Act, sec. 107 definitions), so this is where the trade-offs are settled. Starting in the law's third full fiscal year (by our reading, FY2029), many cities' block grants will be adjusted based on how fast their housing stock grows (GovInfo).
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 local reform point to the tools the new federal law lists for HUD's model guidelines: cutting parking minimums, allowing accessory dwelling units and by-right duplexes to fourplexes, adding homes near transit, and standardizing impact fees. Under the law, an eligible city whose housing growth improves by less than the median can have its block grant cut by 10% (GovInfo).

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.
The Chicago upzoning study found that property values rose near transit while new permits did not (Freemark). The federal law asks HUD's guidelines to include "mechanisms to preserve affordability, limit disruption of low-income communities, and prevent displacement of existing residents". They will also cover reforms to "protest petition statutes" and faster by-right review (GovInfo), which could change how much say neighbors have over individual projects.

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.
Where to look: the Census Building Permits Survey for permits by city or county (Census); HUD Fair Market Rents for your metro (FY2027 figures are published) (HUD USER); American Community Survey 1-year data for places of 65,000 or more (Census, guide to ACS 1-year and 5-year data); and your city's zoning map, comprehensive plan and permit dashboard.

Notes at city scope
- ▸Most of the decision sits in the local zoning code and permit process.
- ▸Ask how long a typical permit takes here, not just what is allowed.
- ▸Tenant protections are usually set at this level too.
