Recreational marijuanalegalization is a hot-button topic, and the debate is now entering the real
estate industry. With more states legalizing recreational use, every home buyer needs to know
how housing markets are affected by this cultural shift. Opponents of legalization stress increases
in crime that lead to lower property values, while supporters highlight the potential economic
benefits. We decided doing a deep dive into the available MLS data and combining it with
dispensary license data was the only way to settle the debate.
Three pivotal questions guided our research:

2. How does marijuana legalization impact crime rates, and how do changes in crime impact
home values?
3. How do retail dispensaries impact local home values?
Digging into Zillow's historical home price indexlrl we can shed some light on these questions
(more information on our methodology can be found here).
Key Insights
Cities that allow retail dispensaries saw home values increase $22,888 more than cities
where marijuana is illegal from2014 to 2019 (controlling for population and initial home
values)
CATO research supports our findings, suggesting homes close in proximity to marijuana
retail dispensaries increase in value
For cities where only medicinal marijuana is legal, home values increased at a
comparable rate to cities where marijuana is illegal; a statistically significant increase in
home values could not be attributed to medicinal marijuana legalization
States that legalize recreational cannabis see an immediate bump in home values
following legalization, even without retail dispensaries opening up. From 2017 to 2019,
cities where recreational marijuana is legal saw home values increase $6,337 more than
cities where marijuana is illegal (controlling for population, initial home values, and
GDP).
Recreational Dispensaries Lead to Higher Local Home Values
Public concern around legalizing recreational marijuana usually focuses on elevated crime rates
Elevated crime rates lead to lower property values and poor real estate investments, so the
narrative goes. In fact,42%o of Canadian's believe a cannabis dispensary will have a negative
impact on local home values according to a2018 studyt2l.
Our research reveals the opposite is true: On average, in states where recreational marijuana is
legal, cities with retail dispensaries saw home values increase $22,888 more than cities where
marijuana is illegal from2014 to 2019. Per a CATO Institute study[3], homes close to retail
dispensaries (within 0.1 miles) increased in value approximately 8.4 percent compared to those
further away. This effect appears to bring up the entire city's home values at a rate higher than
the national average. Real estate agents can use this data to encourage home buyers that are
scared off by retail dispensaries near their homes; based on the research, retail dispensaries don't
impact home values like liquor stores.
Colorado's first retail dispensaries opened in January 1,2014, and medical and recreational sales
have generated over $948,000,000 in tax revenue[4]. Denver has 180 dispensariet[sl, the most of
any Colorado city, and its housing market has seen unprecedented growth since recreational
legalization in2012.
Since Denver retail dispensaries opened their doors in January 1,2014 residential property
values have increased 67.\Yo, the most significant growth in over a two decades.

Denver is a clear-cut example of dispensaries raising residential property values, but dispensaries
have helped bring up property values all around Colorado. Cities in Colorado with dispensaries
have higher than average property value growth compared to the national average.
Colorado and Washington, the first states to legalize cannabis for recreational use, have both
seen above average home values since opening their first dispensaries in2014. Colorado homes
have increased by 58o/o, and Washington home values have increased 57Yo in the five years since
legal commercial sales began.
While there are tax benefits to legalizing marijuana medicinally, there was not a statistically
significant increase in cities where only medicinal marijuana is legal.
So, why does recreational legalization and retail dispensaries lead to homing price boosts?
According to a2017 study from the University of Mississippi, recreationallegalization "attracts
more home buyers, including marijuana users as well as entrepreneurs and job seekers."
Businesses start to pop up, and job seekers flock to these cities, driving up the demand for
housing and retail space.
Takeaway #2: The Connection Between Cannabis Legalization and Crime is Still
Hazy
There's no denying it: Colorado has seen a steady uptick in crime since 2072t61. Violent crimes in
Colorado have increased 25 percent since 2013 after an initial bump in crime in2012.
Similar violent crime trends can be seen in Washington since recreational marijuana was
legalized. And at first glance, these statistics are disconcerting.
However, these graphs are meaningless without national context. A closer look at nationwide
crime statistics reveals a more nuanced picture. The crime rate (crimes per 100,000 citizens)
increases in Washington and Colorado are consistent with nationwide violent crime trends since
2014.In fact, Washington and Colorado both have below average violent crime rates.
While the changes in crime rate are consistent with national averages, one point worth noting is
both Washington and Colorado saw increases in violent crime from 2016 to 2017, where the
crime rate slightly dropped nationwide. 2018 will be a pivotal year in the debate over whether
legalizing cannabis has an impact on crime rates, but more data is needed.
The increase of crime in these areas (regardless of attribution) does not have an impact on
housing prices. Legalizing cannabis for commercial sale allows for taxation and measurable
economic growth, and investors and the housing markets respond accordingly.
Using Colorado and Washington as case studies, it's clear that the market benefits from
marijuana legalization outweigh the potential costs in terms of home values. Further research in
different markets over longer time tables is needed to determine true causality between
marijuana legalization and crime (this study will be updated when 2018 crime statistics are
released).
While the correlation between cannabis and crime remains hazy,the positive effect on housing
markets can't be denied.
In addition to higher home values, home sellers in Colorado and Washington have enjoyed fewer
days on market compared to the national average, particularly in the last few years. Following
legalization in2012, there was a significant decrease in days on the market for both states.
Recreational Cannabis Legalization Leads to an Initial Bump in Home Values,
Even Without Commercial Sales
Another key finding is that marijuana has a clear impact on property values immediately after it's
legalized for recreational use. Given the slow nature of the American political system, bills take
time to become law, and it can be years before the first recreational dispensaries open their
doors. Many states that approved recreational marijuana still haven't passed measures to have
regulated and legal markets for commercial sales.
California, Maine, Massachusetts, Michigan, and Nevada all approved recreational marijuana
legislation in2016, but only California, Nevada, and Maine allow for commercial sales.
Interestingly, all of the states thatlegalized in 2016 saw above average home values immediately
after their respective bills were passed.
This suggests simply legalizing marijuana recreationally leads to an initial bump in home values,
regardless of the economic and tax benefits. States thatlegalize recreational cannabis see an
immediate bump in home values following legalization, even without retail dispensaries opening
up. From 2017 to 2019, cities where recreational marijuana is legal saw home values increase
$6,337 more than cities where marijuana is illegal. Investors see the opportunity to enter a new
market, and home values respond.
Digging into specific housing markets, San Jose (Zillow's hottest housing market two years
running) saw its sharpest historical two-year increase in home values, a $303,200 increase,
following legalization in November 2016. Sales of recreational marijuana didn't begin until
January 2018, but the housing market responded immediately.
Silicon Valley's housing market has been red hot for years, but after legalizing recreational
marijuana, Silicon Valley experienced the highest percentage growth in years. Cities like Los
Altos, Palo Alto, and Saratoga that experienced minor home value declines in20l6 rebounded in
2018 with record breaking home sale prices. 2018 saw the highest percent increase across the
valley since 2014.
Silicon Valley's innovative tech companies are the primary driver of its housing market,
recreational marijuana's impact on home prices can't be ignored. But booming tech cities aren't
the only ones seeing home values rise. Even more modest cities with smaller economies like
Redding, CA have seen home values jump after recreational legislation was passed. Home values
increased 3.75% from November 2015 to November 2016. After the bill was approved, home
values jumped7.35oh from November 2016 to November 2017.
One outlier worth discussing is Washington D.C. While the capital legalized recreational
cannabis with Initiative 7l in2014, commercial sales are not legal. Residents are allowed to
grow and maintain up six plants and carry up to two ounces of marijuana, but no exchange of
money or goods is allowed. There are restrictive laws on consuming marijuana: smoking in a
public space is a $100 fine and smoking in a parked car can result in a DUI.
The lack of a regulated market has resulted in slower growth for the D.C. area compared to the
national average. If cannabis sales aren't legal, money won't flow back into the market, and
housing prices won't respond over the long term. Investors might initially jump at the
opportunity, but until a legitimate market is established, true market gains can't be realized.
Conclusion
Investing in a housing market after recreational legalization is a safe bet. Real estate investors
should look for areas where commercial licenses for marijuana have been requested, as homes
within close proximity to dispensaries tend to have higher home values. Of course, bureaucratic
red tape can slow progress and delay property value growth.
Homeowners and buyers might become spooked by cherry-picked statistics about rising crime
rates in areas where cannabis is legal, but rising crime rates haven't impacted home prices in the
states where marijuana has been legal the longest.
The data suggests real estate investors can find blazinghousing markets in cities where
recreational cannabis is legalized.
Methodology
Using housing data from Zillow and the state population estimates in 2018 from the U.S. census,
we ran a multiple regression analysis to determine the relationship between legalizingmarijuana
and housing prices. We compared the home value increase from 201 7 to 2019 between cities
where marijuana is legalized recreationally, cities where marijuana is legalized medicinally, and
cities where marijuana is illegal, while controlling for population and initial home value for each
city in 2017.
Using housing data from Zillow for all cities where recreational marijuana is legalized and the
state population estimates in 2018 from the U.S. census, we ran a multiple regression analysis to
determine the relationship between dispensaries and housing prices. We compared the home
value increase from 2014 to 2019 between cities where dispensaries can sell recreational
marijuana and cities where recreational selling from dispensaries is illegal, while controlling for
population and initial home value for each city in2014.
