119-HR-5907 Investigative Journalist Impact Analysis

Summary

What the bill does. H.R. 5907 authorizes HUD grants to help localities select and publish pre‑reviewed designs (“pattern books”) for duplexes to small multiplexes (≤25 units), prioritizing high‑opportunity/infill areas, with a 10% rural set‑aside, public reporting, and potential grant clawbacks if designs aren’t adopted within five years. A Senate companion (S.2361) sets similar parameters and explicitly allows technical assistance. [1]Congress.gov / Library of Congress — Text - S.2361 - Accelerating Home Building…

Why it matters. Streamlined approvals can trim months from project timelines and lower regulatory soft costs; pre‑approved ADU and standard‑plan programs show same‑day to weeks‑long plan checks versus months under traditional review. But pattern books don’t override zoning, infrastructure, or financing bottlenecks, so realized effects will vary widely by local context.

Context metrics above come from Up for Growth’s 2023 report; NAHB/NMHC’s multifamily cost survey; and Pew’s analysis of California’s SB 35 streamlining.

Economic Effects

• Permitting time savings: Pre‑reviewed designs can cut plan‑check to same‑day issuance in programs like San José’s, and four weeks for county pre‑approved plans—reducing carrying costs and uncertainty. [6]City of San José — Preapproved ADUs | City of San José[7]County of Santa Clara — Pre‑Approved ADU Program | County of Santa Clara
• Regulatory soft‑cost relief: With regulations averaging 40.6% of multifamily development cost, any reduction in design review iterations and permitting steps targets a large cost driver. [4]NAHB / NMHC — New Research Shows Regulations Account for 40.6 Percent of Apartm…
• Supply‑side price effects: New market‑rate construction tends to ease nearby rents (≈5–7% reductions near new buildings), suggesting that faster approvals enabled by pattern books could modestly dampen local rent growth where projects proceed. [9]The Review of Economics and Statistics (MIT Press) — Local Effects of Large New…
• Selection levers: The bill directs HUD to weigh whether applicants have also reduced land‑use and permitting barriers—linking grants to broader pro‑supply reforms that are often necessary for uptake (e.g., allowing middle housing by‑right). [1]Congress.gov / Library of Congress — Text - S.2361 - Accelerating Home Building…
• Macroeconomic context: The U.S. remains millions of homes short; accelerating small‑scale infill can incrementally close gaps without large infrastructure outlays. [8]Up for Growth — 2023 Housing Underproduction in the U.S.

Social Effects

• High‑opportunity siting: Prioritization of “high opportunity areas” aligns with evidence that children moving to lower‑poverty neighborhoods experience higher adult earnings and college attendance; siting matters as much as unit count.

• Mixed‑income outcomes: Reviews find consistent gains in perceived safety and housing quality for low‑income residents, but limited evidence of direct employment or income gains absent additional supports; design alone won’t deliver mobility. [11]Web search · turn 13 #1
• Definition alignment: The bill’s use of “high opportunity area” is consistent with FHFA duty‑to‑serve usage, aiding administrative clarity when targeting sites. [12]LII / Cornell Law School — 12 CFR § 1282.1 - Definitions (incl. High Opportunit…
• Equity guardrails: Public posting of pattern books and best‑practice dissemination can lower informational barriers for small/minority developers and residents—if implemented with accessible licensing and outreach. [1]Congress.gov / Library of Congress — Text - S.2361 - Accelerating Home Building…

Environmental Effects

• Infill and VMT: Compact, infill housing reduces vehicle miles traveled (VMT) by roughly 20–40% versus conventional sprawl patterns, lowering transportation emissions when projects locate near jobs/services. [5]U.S. EPA — Smart Growth and Climate Change
• Regional air‑quality benefits: Case studies show redirecting households/jobs to infill sites cuts congestion and emissions—pattern books can help standardize such infill typologies at scale. [13]U.S. EPA — Measuring the Air Quality and Transportation Impacts of Infill Devel…
• Material/energy co‑benefits: Standardized plans can simplify compliance with energy codes and enable repeatable, efficient assemblies—though realized GHG gains depend on local grid mix and retrofits. (Generalizable from EPA smart growth findings.) [5]U.S. EPA — Smart Growth and Climate Change

Temporal Analysis

• Immediate (0–2 years): Faster plan review for shovel‑ready small projects; limited by existing zoning, staffing, and utility hookups. [6]City of San José — Preapproved ADUs | City of San José
• Near term (2–5 years): If paired with by‑right entitlements, streamlining can compress approvals from ~7–12 months to 2–4 months in jurisdictions using state‑level tools (e.g., CA SB 35), improving pro formas during volatile rate cycles. [3]The Pew Charitable Trusts — Reforms Spur Faster Housing Approvals in California
• Long term (5+ years): Potential cumulative infill supply increase, modest rent moderation near added units, and reduced transport emissions—contingent on sustained adoption and siting in opportunity‑rich areas.

Unintended Consequences

• Design lock‑in vs. flexibility: Some standard‑plan programs restrict modifications; if local pattern books become de facto design mandates, they can stifle innovation or add soft‑cost friction via stylistic requirements. [14]City of Los Angeles (LADBS) — ADU Standard Plan Program | LADBS[15]Montgomery Planning (MD) — Community invited to learn about the Planning Board…
• Not a zoning override: Pattern books cannot legalize housing types where zoning still bans them; HUD’s scoring for jurisdictions that reduce regulatory barriers partially mitigates, but uptake will lag without parallel reforms. [1]Congress.gov / Library of Congress — Text - S.2361 - Accelerating Home Building…
• Utility/coordination bottlenecks: Even with plan approval, grid upgrades and service connections can delay delivery (e.g., PG&E delays for ADUs), limiting the realized speed gains. [16]San Francisco Chronicle — PG&E is delaying ADU construction in California, buil…
• Cost risk from design standards: If pattern books layer on prescriptive façades/materials, they can function like added design standards—an identified contributor to higher development costs. [4]NAHB / NMHC — New Research Shows Regulations Account for 40.6 Percent of Apartm…
• Capacity gaps in rural areas: The 10% rural set‑aside and technical assistance authority help, but thin staffing and contractor scarcity may blunt near‑term production. [1]Congress.gov / Library of Congress — Text - S.2361 - Accelerating Home Building…
