No. There are a number of models out there, but the definition of "Club" is a 501(c)(3) that is registered as a "Club" with Cal South and/or the gaming leagues. The two basic models are:
The "Company" Club, where there is a single entity with multiple locations/branches: Arsenal, Legends,
The "Franchise" Club, where there is a "brand" that is licensed to multiple entities: Surf, LA Galaxy, Slammers, etc.
To compound the matter, sometimes a "Company" club has a few "Franchise" locations. For example, Legends and Arsenal both have North and South under the Company umbrella and the other Legends/Arsenal's are franchises (although Legends has a few more company clubs). CDA Slammers have a regions under a single entity and then there are other entities for some of the other locals.
You have to trace it all back to the "entity" operating the club. When looking at the Club Info on the SCDSL site or CSL site, if the names for the DOC are basically the same, then you likely have a "Company" club and "club passing" would be allowed between different locals because the core business unit is the same. If the leadership names are different, then you likely have a "Franchise" club system (e.g. San Diego Surf, Murrieta Surf, OC Surf, etc.) and club passing would not be allowed.
On the CSL side of the fence, the problem can be even more difficult to ascertain because there are/have been a number of CSL "clubs" that were proxy's for other clubs. Thus, a particular club registered with CSL might have multiple team brands playing under its entity. These clubs exist to allow the myriad of small clubs (just a few teams) to enter a gaming league and in theory club passing would be allowed. I've seen this occur most frequently in sparsely populated locations.
