This page provides an overview of recreational and medical cannabis (marijuana) laws and regulations that impact local and state government agencies in Washington State, including a map of local regulatory approaches and examples.
With the passage of Initiative 502 in 2012, the state of Washington moved to a comprehensive regulatory approach on cannabis (marijuana), with state-licensed producers, processors, and retailers.
As of July 1, 2016, the production and marketing of medical cannabis was incorporated into the same regulatory framework as recreational cannabis, with some variations such as the allowance of medical marijuana cooperatives. The state Liquor and Cannabis Board (LCB) has a Cooperatives FAQs page.
In 2022, the state legislature passed 2SHB 1210, a law that replaces all references to "marijuana" in state statutes (RCWs) and regulations (WACs) with the word "cannabis." Cannabis is a more scientific word, and its use is consistent with the current regulation of this substance.
All cannabis licensing is regulated and enforced by the Washington State Liquor and Cannabis Board (LCB).
Any sale of recreational or medical cannabis other than by a state-licensed retailer is criminal, as is the production or processing of cannabis for sale outside the state-licensed regulated system.
The primary statutes for recreational cannabis are codified in chapter 69.50 RCW, beginning with RCW 69.50.325; the medical cannabis statutes are located in chapter 69.51A RCW. The Liquor and Cannabis Board regulations for cannabis are found in chapter 314-55 WAC.
Cities, towns, and counties in Washington State can choose to prohibit or to designate appropriate zones for state-licensed cannabis businesses because Washington local governments have authority to enact legislation regulating land uses within their jurisdictions. However, LCB has final authority over whether to grant or deny a state license to operate a cannabis business in Washington State.
Cities, towns, and counties may also file objections to the granting of a state license at a particular location and the Liquor and Cannabis Board must “give substantial weight to objections,” but it is still up to the LCB to make the state license decision. See RCW 69.50.331(10).
This section provides an overview of the land use related statutes regulating cannabis businesses.
Minimum Buffer Distance
RCW 69.50.331(8) requires licensed cannabis producers, processors or retailers to be located at least 1,000 feet from the following entities:
- Elementary or secondary school;
- Recreation center or facility;
- Child care center;
- Public park;
- Public transit center;
- Library; or
- Any game arcade (where admission is not restricted to persons age 21 or older).
The 1,000 feet buffer distance must be measured as the shortest straight line distance from the property line of the proposed business location to the property line of any of the entities listed above. See WAC 314-55-050 (10). Definitions for the entities are found at WAC 314-55-010.
Local governments may reduce the 1,000 feet buffer to 100 feet around all entities except elementary schools, secondary schools, and public playgrounds by enacting an ordinance authorizing the distance reduction. See RCW 69.50.331(8)(b).
Residential Properties and Small Rural Parcels
The State Liquor and Cannabis Board (LCB) will not issue licenses for cannabis producers, processors, and retailers on property that is used as a residence because law enforcement officials must have access to the premises for inspections without a warrant (WAC 314-55-015(5)). However, note that state law still allows a medical cannabis patient or caregiver to have a designated number of cannabis plants located within a residence (RCW 69.51A.040).
Local governments are specifically authorized to prohibit licensed cannabis businesses on lands zoned for residential use or rural use with a minimum lot size of five acres or smaller (RCW 69.50.331(9)).
Medical Cannabis Cooperatives
The statutes on “collective gardens” were repealed effective July 1, 2016 and replaced by a statute authorizing “cooperatives” for the growing of cannabis for medical use (RCW 69.51A.250). The statutes on cooperatives are more restrictive than the prior collective gardens provisions. Below is a list of some of these restrictions:
- Cooperatives must be located in the domicile of one of the participants (RCW 69.51A.250(7)).
- Cooperatives may have up to a maximum of four qualifying patients or providers as members (RCW 69.51A.250(1)).
- Participants may grow up to a maximum of 60 plants and possess up to 72 ounces of usable cannabis (RCW 69.51A.250(6)(a)).
- None of the cannabis from a cooperative can be sold to others (RCW 69.51A.250(6)(e)).
Local governments are authorized to prohibit medical cannabis cooperatives (RCW 69.51A.250(3)(c)).
City and county zoning measures adopted since cannabis was legalized are diverse. Some jurisdictions have enacted total prohibitions, while others have allowed cannabis businesses in appropriate zoning districts (retail cannabis businesses in retail zones, outdoor cannabis production in agricultural zones, and indoor cannabis production and processing in industrial zones).
The state map below contains information regarding how local governments across the state have zoned for state-licensed cannabis businesses. MRSC attempts to provide accurate and complete data from all jurisdictions in Washington. For questions or comments regarding this map, please email MRSC.

Limit Number of Retail Cannabis Businesses Allowed
Through the state agency rulemaking process the Liquor and Cannabis Board has adopted regulations on the maximum number or retail store licenses that will be issued for each county, and for some of the cities and towns in each county.
Some jurisdictions, such as the ones below, have adopted ordinances that limit the number of retail cannabis business licenses/stores at a number below what the LCB allows. There are varying viewpoints about whether state law allows such regulations.
- Everett Ordinance No. 3486-16 (2016) – Limits the number of retail stores allowed in the city to a maximum of five. The city shall review the maximum number of retail stores allowed before June 1, 2018, to determine whether this maximum number should be changed.

All licensed cannabis businesses operating in Washington State must comply with a wide range of local, state, and federal regulations and codes. To ensure and enforce compliance, local government officials and building inspectors must understand which regulations and codes apply and which agency has the authority to enforce them.
The Interagency Resource for Achieving Cooperation and a partnership of Washington Municipalities and industry representatives have created some guidelines to facilitate the process of understanding these regulations in the document Regulatory Guidance for Cannabis Operations (2015). With the same goal, MRSC prepared the following list of applicable regulations and codes clarifying which government agency is responsible for enforcing them.
- Building, plumbing, electrical and fire codes are enforced by the local government jurisdiction where the business is located.
- Smells and fumes are generally a nuisance issue handled by local government.
State and Local Government
- Wastewater discharge is managed through the agency operating the local treatment plant. Procedures used for disposal of cannabis solid waste that is not "dangerous waste" must be handled properly (WAC 314-55-097(4)). Disposal of solvents, pesticides, fertilizers and materials classified as "dangerous waste" will need to be done in accordance with state regulations (WAC 314-55-097).
- Exterior signage is normally a matter of local concern, but state law places strict limits on signage for cannabis businesses (WAC 314-55-155). The local government will enforce local signage requirements. Violations of state signage regulations should be brought to the attention of the Liquor and Cannabis Board. Local governments could adopt the WAC signage requirement as a local regulation and then also enforce that stricter standard. There are also state regulations for signs that must be placed within cannabis businesses (WAC 314-55-086). Enforcement is the responsibility of the Liquor and Cannabis Board.
- Fencing is normally a local concern, but state law places special requirements for cannabis producers who grow plants outside (WAC 314-55-075). Enforcement of the WAC fencing requirement is the responsibility of the Liquor and Cannabis Board, though a local government could adopt the WAC standard and also enforce that regulation.
- Security requirements for licensed cannabis businesses are set out in state regulations (WAC 314-55-083). Liquor and Cannabis Board staff will inspect and make sure that all requirements are met.
- Safety issues raised by the use of volatile compounds by processors will be dealt by the Occupational Safety and Health Board Administration (OSHA).
The State imposes a 37% cannabis excise tax at the time of retail sale (RCW 69.50.535). In addition, most cannabis sales are subject to normal retail sales taxes, and cannabis businesses are subject to business and occupation taxes. However, RCW 82.08.9998 exempts sales of certain medical cannabis products and high CBD/low THC products from retail sales tax. For more information, see the Department of Revenue page on Taxes Due on Cannabis.
The revenue from the 37% excise tax is shared with cities, towns, and counties (RCW 69.50.540), with some of the revenues distributed on a per capita (population) basis and the rest distributed based upon actual cannabis retail sales. Cities, towns, and counties that prohibit cannabis producers, processors, or retailers are not eligible for per capita distributions.
The portion of state distribution attributed to retail sales is certified by the LCB by September 15 of each year for distribution in the forthcoming state fiscal year. The state treasurer will make the transfers to local governments in four installments, by the last day of each fiscal quarter.
Washington State legalizes the possession of specified amounts of cannabis and the private recreational and medical use of cannabis. Under state law licensed cannabis businesses can grow, process and sell cannabis. Police officers may arrest individuals for driving under the influence of cannabis (RCW 46.61.502) and they may issue citations for consuming cannabis in public (RCW 69.50.445).
Employers' rights to enact drug policies prohibiting cannabis use in and outside the workplace under Washington law did not change after the adoption of Initiative 502 in 2012. Except for persons with commercial driver's licenses, state law is silent on the topic of cannabis use and testing in the workplace, and cannabis remains illegal under federal law. Where in force, federal regulations may still prohibit use and mandate testing for cannabis.
For more information on employment-related issues regarding cannabis, see Cannabis in the Workplace FAQs.
In 2020, E2SHB 2870 passed and created a social equity in cannabis program. The program included the establishment of a Social Equity in Cannabis Task Force, responsible to develop policies and recommendations for additional state licenses based on equity. In 2022, the Task Force released their final report.
