Cannabis is legal in California, but the rules that govern how, where, and how much you can buy, possess, and consume it are layered and specific. In San Diego, those rules have evolved significantly over the past year. Whether you are a longtime local consumer, a first-time visitor, or a business owner, here is what you need to know about cannabis law in San Diego in 2026.
State Law: The California Framework
California legalized adult-use recreational cannabis under Proposition 64, which voters approved in November 2016. Under state law, adults 21 and older may legally possess up to one ounce (28.5 grams) of cannabis flower and up to 8 grams of concentrated cannabis at any given time. You may also cultivate up to six plants for personal use at a private residence, provided local ordinances permit it.
Purchasing cannabis must happen through a licensed retailer. It is illegal to buy cannabis from unlicensed sources, regardless of how the transaction is framed. California maintains a comprehensive licensing system through the Department of Cannabis Control, and all licensed businesses are listed on the state's public database.
San Diego City Rules: Retail Limits and Zoning
The City of San Diego caps the number of cannabis retail locations at a maximum of 36 citywide, with no more than four dispensaries permitted per City Council district. This cap has created a competitive licensing environment and kept the total number of retail outlets relatively limited for a city of San Diego's size.
Dispensaries must meet strict zoning requirements, including minimum distance buffers from schools, parks, and other sensitive uses. They must also obtain both state licenses and city permits, satisfy annual inspections, and comply with security, labeling, and inventory tracking requirements.
In August 2025, the San Diego City Council extended operating hours for cannabis retailers, allowing dispensaries to open as early as 6:00 a.m. and operate until 10:00 p.m. The extended hours apply across most of the city, with slight variations for properties within the Coastal Overlay Zone.
National City and the County: A Different Landscape
Each city and unincorporated area within San Diego County sets its own cannabis rules. National City, for example, was an early adopter of consumption lounge permits, enabling Sessions By The Bay to become the first licensed cannabis consumption lounge in the entire county. The unincorporated areas of the county are still working through a new Socially Equitable Cannabis Program, with full implementation expected after the Board of Supervisors certifies the Final Program Environmental Impact Report, anticipated in summer 2026.
Other cities in the county have taken different approaches, with some permitting only delivery, others allowing retail but not consumption, and a few maintaining prohibitions on cannabis business altogether. If you are planning to visit a specific area, it is worth checking local rules in advance.
Where You Can and Cannot Consume Cannabis in San Diego
This is where many consumers run into trouble. Even though cannabis is legal in California, consuming it in most public spaces is illegal. The rules mirror those for tobacco and alcohol in many ways, but with some additional restrictions.
You may consume cannabis on private property with the owner's permission. You may not consume it in any public place, including parks, sidewalks, beaches, or restaurants (unless the establishment is specifically licensed for consumption). You may not consume it in a vehicle, whether you are driving or a passenger. Hotel rooms and short-term rentals vary by property policy.
The opening of Sessions By The Bay's consumption lounge in National City created a licensed, legal alternative for consumers who want to enjoy cannabis socially outside of their home. That option simply did not exist in San Diego County before 2025.
Cannabis Delivery: What Is Legal
Licensed dispensaries in San Diego may offer delivery services. Under California law, delivery must originate from a licensed retail storefront, must be received by the purchaser at the address provided at the time of the order, and cannot be redirected after dispatch. Delivery drivers must carry manifests and follow strict track-and-trace requirements.
Consumers should always use licensed delivery services and verify the license status of any delivery operator. Unlicensed delivery is not only illegal but also exposes consumers to unregulated products.
Penalties for Violations
Consuming cannabis in a public place in California is an infraction punishable by a fine of up to $100. Possessing more than the legal limit is a misdemeanor. Selling cannabis without a license is a felony. Providing cannabis to a minor carries significant criminal penalties and can result in civil liability as well.
For businesses, operating without a proper license, failing to maintain required records, or violating track-and-trace requirements can result in license suspension, revocation, and substantial fines.

One of the most significant policy developments in San Diego cannabis is the rollout of the county's Socially Equitable Cannabis Program. Designed to address the historical harms of cannabis criminalization, the program offers grants, technical assistance, and priority licensing to applicants who were disproportionately impacted by the War on Drugs.
Grant recipients in the first round received $28,000 each, funded through California's Governor's Office of Business and Economic Development. The program represents a genuine effort to ensure that the legal cannabis economy does not simply replicate the inequities of the past, and that the communities most harmed by prohibition have a real opportunity to participate in the regulated market.
Key Takeaways for 2026
To summarize the most important points: adults 21 and older may possess up to one ounce of flower or 8 grams of concentrate. Purchases must be made through licensed retailers. Consumption is permitted on private property and in licensed consumption lounges. Public consumption remains illegal. Delivery is available from licensed retailers. The dispensary cap in the city limits retail options, so knowing your nearest licensed shop matters.
