YIMBY#California

The term started being used in the 1980s as a position in opposition to NIMBYism. By 1991, YIMBY was already an established term and had been since the 1980s, understood to mean "Yes-in-many-backyards".{{cite book |last1=DiMento |first1=Joseph F. |last2=Graymer |first2=LeRoy |format=Paperback |title=Confronting Regional Challenges: Approaches to LULUs, Growth, and Other Vexing Governance Problems : the Sixth Annual Donald G.

A 1993 essay published in the Journal of the American Planning Association entitled "Planners' Alchemy, Transforming NIMBY to YIMBY: Rethinking NIMBY" used 'YIMBY' in general reference to development, not only housing development.{{cite journal |first=Robert W. |last=Lake |date=Winter 1993 |title=Planners' Alchemy Transforming NIMBY to YIMBY: Rethinking NIMBY |journal=Journal of the American Planning Association |volume=59 |issue=1 |pages=87–93 |doi=10.1080/01944369308975847}}

The pro-housing YIMBY position emerged in regions experiencing unaffordable housing prices. The Guardian and Raidió Teilifís Éireann say this movement began in the San Francisco Bay area in the 2010s due to high housing costs created as a result of the local technology industry adding many more jobs to the region than the number of housing units constructed in the same time span.{{cite news |url=https://www.theguardian.com/cities/2017/oct/02/rise-of-the-yimbys-angry-millennials-radical-housing-solution |title=Rise of the yimbys: the angry millennials with a radical housing solution |first=Erin |last=McCormick |location=San Francisco |date=October 2, 2017 |newspaper=The Guardian}}{{Cite journal |last=Whelan |first=Sean |date=2021-02-25 |title=Yimby movement aims to solve housing woes in London |url=https://www.rte.ie/news/uk/2021/0225/1199455-yimby-movement/ |journal=RTÉ |language=en}}

California YIMBY, the first political YIMBY group, was founded with the funding of Bay Area tech executives and companies. Dustin Moskovitz (Facebook, Asana) and his wife Cari Tuna donated $500,000 via their Open Philanthropy foundation; Nat Friedman (Xamarin, GitHub) and Zack Rosen (Pantheon Systems) donated another $500,000. Another $1 million donation came from the online payments company Stripe.{{cite web |last1=Bronstein |first1=Zelda |title=California's Yimby's |url=https://www.dollarsandsense.org/archives/2018/0918bronstein.html |website=Dollars and Sense |publisher=Economic Affairs Bureau |access-date=12 June 2024}}

The YIMBY movement consists of various factions with differing motivations, the debate over YIMBY policies is not limited to a single political line, with YIMBY activists aligning from across the political spectrum.{{cite web |last1=Schuetz |first1=Cassidy Pearson and Jenny |title=Where pro-housing groups are emerging |url=https://www.brookings.edu/blog/the-avenue/2022/03/31/where-pro-housing-groups-are-emerging/ |website=Brookings |date=31 March 2022}}

Surveys of both the public and elected officials show that Democrats are more likely than Republicans to support dense, multifamily housing.{{Cite journal |last1=de Benedictis-Kessner |first1=Justin |last2=Jones |first2=Daniel |last3=Warshaw |first3=Christopher |date=2024 |title=How partisanship in cities influences housing policy |url=https://onlinelibrary.wiley.com/doi/10.1111/ajps.12856 |journal=American Journal of Political Science |language=en |doi=10.1111/ajps.12856 |issn=0092-5853|url-access=subscription }} A 2024 study of mayors and city councils shows that "electing a Democrat as mayor leads to increased multifamily housing production. These effects are concentrated in cities where councils have less power over land use changes."

A major part of the political coalition aligned with the movement includes environmentalists and proponents of sustainability who support measures to legalize higher density. Urban development with higher density reduces the population’s need to travel by automobile, and thus, cities’ need to develop car-based infrastructure, which in the United States accounts for 29% of all greenhouse gas emissions.{{Cite web |last=US EPA |first=OAR |date=2015-09-10 |title=Carbon Pollution from Transportation |url=https://www.epa.gov/transportation-air-pollution-and-climate-change/carbon-pollution-transportation |access-date=2024-03-15 |website=www.epa.gov |language=en}}{{cite web |title=A Vision for the Future of Cities |author=Sage Van Wing |date=May 27, 2022 |website=OPB |url=https://www.opb.org/article/2022/05/27/a-vision-for-the-future-of-cities/ |access-date=September 13, 2024}}

Proponents of free market economics back zoning deregulation from a different perspective. They see increased housing density as a way to stimulate economic growth, foster innovation, and improve productivity by encouraging the free flow of people and ideas. In their view, deregulated housing markets enable more efficient land use, reduce housing costs, and enhance individual property rights.

A 2019 study by Chang-Tai Hsieh and Enrico Moretti in the American Economic Journal found that liberalization of land use regulations would lead to enormous productivity gains. The study estimated that strict land use regulations "lowered aggregate US growth by 36 percent from 1964 to 2009."{{Cite journal |last1=Hsieh |first1=Chang-Tai |last2=Moretti |first2=Enrico |date=2019 |title=Housing Constraints and Spatial Misallocation |journal=American Economic Journal: Macroeconomics |language=en |volume=11 |issue=2 |pages=1–39 |doi=10.1257/mac.20170388 |issn=1945-7707 |doi-access=free}}{{Cite news |date=2019-05-23 |title=How Housing Supply Became the Most Controversial Issue in Urbanism |url=https://www.bloomberg.com/news/articles/2019-05-23/why-urbanists-are-arguing-about-housing-supply |last=Florida |first=Richard |journal=Citylab |publisher=Bloomberg |access-date=2020-06-19}}{{cite web |title=Hsieh-Moretti on Housing Regulation: A Gracious Admission of Error |website=Econlib |last=Caplan |first=Bryan |date=2021-04-05 |url=https://www.econlib.org/a-correction-on-housing-regulation/ |access-date=2022-01-03}}

Similarly, a study conducted by the National Bureau of Economic research also estimated that deregulating land use in the United States would lead to productivity gains, with domestic output projected to increase between 3–6% and economic well-being lifted by 3–9%.{{Citation |last1=Babalievsky |first1=Fil |title=The Impact of Commercial Real Estate Regulations on U.S. Output |date=November 2023 |type=Working Paper |url=https://www.nber.org/papers/w31895 |access-date=2024-03-15 |series=Working Paper Series |doi=10.3386/w31895 |last2=Herkenhoff |first2=Kyle F. |last3=Ohanian |first3=Lee E. |last4=Prescott |first4=Edward C.|publisher=National Bureau of Economic Research |location=Cambridge, MA }}

The free market faction, unlike liberals, believes that while higher-density housing should be allowed, it shouldn't be forced within existing cities solely for environmental reasons, with figures like libertarians,{{cite web |last=Murphy |first=Timothy |title=To Make Housing Affordable, Prioritize Abolishing Growth Boundaries, Not Ending Density Restrictions |url=https://reason.com/2023/04/25/to-make-housing-affordable-prioritize-abolishing-growth-boundaries-not-ending-density-restrictions/ |website=Reason |publisher=Reason Foundation |date=2023-04-25 |access-date=2024-09-13}} and moderate free-market advocates like Matt Yglesias{{cite web |last=Yglesias |first=Matthew |author-link=Matthew Yglesias |title=Ten years of YIMBYism have accomplished a lot |url=https://www.slowboring.com/p/ten-years-of-yimbyism-have-accomplished |website=Slow Boring |publisher=Substack |date=2023-09-07 |access-date=2024-09-13}} opposing urban growth boundaries.

Similarly, requiring a very high inclusionary (i.e., subsidized) percentage for new construction can result in less housing development, as subsidized homes are often more expensive to build than market-rate ones.{{cite web |title=Affordable housing can cost $1 million in California.

Evidence from California suggests that support for development is often higher when the development is less local. For example, a statewide upzoning bill will have more popular support statewide than a new apartment building will have from the immediate neighbors.{{sfn|Dougherty|2020|loc=chapter 2}} This can vary by state.

In recent years similar platforms EHVXL in Eindhoven, DHXL in The Hague and UTRXL in Utrecht were founded.

Other YIMBY groups have been set up in individual London boroughs and in cities suffering similar housing shortages, such as Brighton, Bristol and Edinburgh. The town-builder Create Streets has also argued for intensification of existing streets, for reducing planning risk to enable a more diverse range of housebuilders and for more popular design to discourage NIMBY opposition to homes.

Since 2014, in response to California's housing affordability crisis, several YIMBY groups were created in the San Francisco Bay Area.

The New York Times explained about one organization: "Members want San Francisco and its suburbs to build more of every kind of housing. More subsidized affordable housing, more market-rate rentals, more high-end condominiums."

In 2017, YIMBY groups successfully lobbied for the passage of Senate Bill 35 (SB 35), which streamlines housing under certain criteria, among other "housing package" of bills.

From 2018 to 2020, the lobbying group California YIMBY joined over 100 Bay Area technology industry executives in supporting state senator Scott Wiener's Senate Bills 827 and 50. The bills failed in the state senate after multiple attempts at passage.{{ r | SFC_Yelp_CEO | p=1 | q=Stoppelman gave $100,000 to California YIMBY, a grassroots pro-housing group that sponsored Wiener's bill, SB827.

YIMBY groups in California have supported the split roll effort to eliminate Proposition 13 protections for commercial properties, and supported the ballot measure known as Proposition 15, which would implement this change but failed to pass in 2020.

Since 2012, several YIMBY groups were established in the greater Boston area. One group argues that "...more smart housing development is the only way to retain a middle class in pricey cities like Boston and Cambridge."

Several YIMBY groups, chiefly Open New York, have been created in New York City; according to an organizer: "In high-opportunity areas where people actually really want to live, the well-heeled, mostly white residents are able to use their perceived political power to stop the construction of basically anything," adding that low-income communities don't share that ability to keep development at bay: "Philosophically, we think that the disproportionate share of the burden of growth has been borne by low income, minority or industrial neighborhoods for far too long."{{ r | Curbed_NY_YIMBY }}.

In September 2018, the third annual Yes In My Backyard conference, named "YIMBYTown" occurred in Boston, hosted by that area's YIMBY community. The first YIMBY conference was held in 2016 in Boulder, Colorado and hosted by a group that included Boulder's former mayor, who commented that: "It is clearer than ever that if we really care about solving big national issues like inequality and climate change, tackling the lack of housing in thriving urban areas, caused largely by local zoning restrictions, is key." The second annual conference was held in the San Francisco Bay Area city of Oakland, California. These conferences have attracted attendees from the United States, as well as some from Canada, England, Australia, and other countries.{{ r | NextCity_Stephens }}
