Pasadena has no cryptocurrency-mining ordinance. A commercial mining facility is treated like any data center - no zoning use category, classified case-by-case into the IG industrial zone, and bound by the Chapter 9.36 ambient-plus-5-decibel noise limit on its cooling equipment.
Pasadena's Municipal Code contains no crypto-mining, bitcoin, or blockchain use category and no energy cap targeting mining. A warehouse of mining rigs draws power and produces heat and noise like a data center, so Planning would classify it into the closest listed use - Industry or Communications facilities - and site it in the IG (Industrial, General) zone, reviewed case-by-case. Continuous cooling noise must stay within Section 9.36.090: no more than 5 decibels above ambient at the property line, plus a 5-decibel penalty for the steady tone. Home mining is ordinary residential use, subject to the same property-line noise limit. Pasadena Water & Power's limited grid capacity constrains any large load.
There are no crypto-specific penalties. A commercial mining operation outside the IG zone, or without a required Conditional Use Permit, is a zoning violation, and cooling noise over the Chapter 9.36 ambient-plus-5 limit is enforced by the city.
