A small west-Fresno County oil town turned early-mover cannabis city — Coalinga famously converted the former Claremont Custody Center into a large cannabis manufacturing facility through Ocean Grown Extracts and has permitted cultivation, manufacturing, and distribution since 2016. Here's the local pathway.

These aren’t hypothetical. These are the engagements we’re called in on — usually after someone tried to save $30,000 by doing it themselves.
Coalinga is a city of roughly 17,000 on the west side of Fresno County, historically built on oil production (the original 1860s coal-and-oil discovery that gave the city its name still echoes in the economy) and later hit hard by the closure of the Claremont Custody Center in 2011. In 2016 the city made national cannabis-industry news when it approved the sale of the vacant 77,000-square-foot prison facility to Ocean Grown Extracts, which converted the building into one of California's largest indoor cannabis manufacturing and cultivation operations. That decision signaled Coalinga's intent to use commercial cannabis as an economic-development tool, and the city has since built out a comparatively deep local program for its size.
Coalinga permits cannabis cultivation (indoor and mixed-light), manufacturing (both non-volatile and volatile extraction), distribution, and testing under its local ordinance. Retail storefronts are permitted under a separate, smaller-scale framework, though the city's market identity has always been industrial rather than retail. The local pathway runs through the Coalinga City Clerk (Cannabis Business Permit) and the Planning Department (Conditional Use Permit), with zoning confined to designated industrial and heavy-commercial districts. Sensitive-use buffers follow standard 600–1,000 foot requirements from schools, day cares, and youth centers, with additional setbacks from residential zones for volatile-extraction operations.
The Ocean Grown Extracts conversion remains the flagship Coalinga cannabis project and a frequent case study in how a small city can use an industrial cannabis footprint to create local employment, tax revenue, and facility-lease income. The 77,000-square-foot former prison houses cultivation rooms, extraction suites, manufacturing lines, and distribution staging in a single tightly-secured facility — a vertically-integrated configuration that matches how Coalinga's ordinance is structured. Several other smaller cannabis operators have located manufacturing and distribution operations in the city's industrial zones since 2017, drawn by the permissive ordinance, low land and lease costs, and the west-Fresno logistics advantage along I-5.
For county context outside city limits (unincorporated Fresno), see the Fresno County page. Enforcement in Coalinga is handled by the Coalinga Police Department in coordination with Fresno County Sheriff and DCC investigators. The dominant compliance friction for Coalinga cannabis operators is METRC reconciliation across high-volume manufacturing workflows, CUPA/CERS hazardous-materials management for extraction facilities, fire-code compliance on closed-loop extraction systems, and CDTFA cannabis-tax reporting on cross-jurisdictional transfers. PSI (pressure system inspection) requirements are a recurring issue for volatile-extraction operators. Before filing a Coalinga application, verify current zoning overlays, buffer posture, and tax rates — the city's program is mature but specific parcel and ordinance details still move.
These details change. Verify current posture with Coalinga Planning or the City Clerk before filing.
Operators underestimate Coalinga because the ordinance reads welcoming — every license type permitted, low land cost, a city council that wants the tax base. The actual work is sequencing eight different agencies through a manufacturing-scale build: PSI for closed-loop extraction, CUPA/CERS hazmat for the solvent program, Fire on California Fire Code Chapter 39, Building & Safety on the pressure-vessel plan review, Planning on the CUP, the City Clerk on the Cannabis Business Permit, DCC on the state license, and CDTFA on the cross-jurisdictional tax reconciliation.
The Ocean Grown Extracts prison conversion is useful context but misleading as a template. A 77,000-square-foot retrofit at that scale hides the ordinary friction points: M-1 parcel verification, residential-zone setback re-triggering when a daycare opens mid-engagement, the I-5 logistics advantage that becomes a CDTFA transfer-tracking liability when flower moves from cultivation to manufacturing to distribution inside the same campus under shared ownership.
None of this is hidden. It’s in the Coalinga Municipal Code, in the PSI inspector’s reference sheets, in CCR Title 4 §15048. But threading it into a single coherent submission, across a single coherent timeline, across all eight parallel review tracks — that’s the work most operators didn’t scope when they signed the industrial-shell lease.
