Thinking about growing industrial hemp in California?
Learn the questions to ask, the official starting points to consult, and what to investigate before buying seed or planting.
Fiber & grain focusPartial official-source reviewCounty research follows state approval
Official state starting points reviewed October 10, 2026: This guide now includes agency, licensing, and cost information from linked government pages. It is not a complete compliance determination. County requirements, planting-year changes, and full application details still require confirmation.
STEP 1 · BEFORE YOU SPEND A DOLLAR
Check whether your growing plan is feasible.
Identify your proposed location, whether you intend to grow fiber or grain, and who may buy your crop. Before committing funds, verify the licensing program that applies to your location and planting year.
First official starting point
USDA Agricultural Marketing Service — Domestic Hemp Production Program
STATE-SPECIFIC RESEARCH · EARLIER SOURCE REVIEW OCTOBER 10, 2026
Start with the responsible agency
California Department of Food and Agriculture (CDFA); county agricultural commissioner handles cultivation registration
industrialhemp@cdfa.ca.gov · (916) 518-3283
California requires industrial hemp growers to register with the county agricultural commissioner before cultivation; confirm local restrictions and approved sites/cultivars with that office.
What to do first
Find your county agricultural commissioner and submit the appropriate grower registration before planting.
Published fees and costs
CDFA currently lists a $900 annual grower registration fee; a county may assess additional local fees. Confirm current amounts with the county commissioner.
This is a source-reviewed starting point, not an exhaustive list of requirements. Confirm current rules with the licensing authority for your crop year.
USDA lists a state hemp production plan for California. Start with the state program, but verify the responsible licensing authority for your specific parcel, particularly on tribal land.
Contact details were published in USDA's March 2025 directory and have not been re-confirmed directly with the state for 2026. Check the linked agency page for changes.
Scope: The plan designation and directory contact are supported by USDA listings; they do not verify application forms, fees, deadlines, county zoning, or the latest agency personnel. Those items remain subject to direct confirmation.
YOUR LOCATION
Where in California will you grow?
Local zoning, land use, and municipal requirements can depend on your specific parcel. HempHQ has not verified county ordinances for this state. Enter a county to see a research reminder, not a zoning determination.
STATE REQUIREMENTS · ADDITIONAL ITEMS TO CONFIRM
What you'll need to confirm
01
Identify the licensing authority
Use USDA's state and tribal plan directory to determine the relevant licensing program, then confirm directly with the agency that handles your location.
Ask the licensing authority about application requirements, deadlines, eligibility, background checks, growing-site registration, and approvals needed before planting. Confirm the latest California requirements directly with the licensing authority; this checklist does not cover every rule.
03
Check planting and reporting rules
Confirm which varieties and seed records are required, how lots and growing locations are reported, and any applicable USDA Farm Service Agency reporting obligations.
Ask the applicable licensing authority how pre-harvest sampling, laboratory testing, harvest windows, handling, and recordkeeping work for your planting year.
FEES · SEE SOURCE-REVIEWED DETAILS ABOVE
What might the process cost?
Some published fees are summarized in the state-specific section above. Other costs remain unverified. Obtain the current fee schedule directly from the responsible authority. Also budget for land, seed, labor, equipment, testing, storage, transport, and a realistic buyer or processor.
We do not publish estimated government fee totals without a dated official source; see the source-reviewed section where available.
