Fremont has no cryptocurrency-mining ordinance. A commercial mining operation is treated as data processing and hosting - permitted by right in the I-S, I-T, and I-G industrial districts and bound by the Section 18.50.040 property-line noise standards, design review, and hazardous-materials review.
Fremont's Municipal Code has no crypto-mining, bitcoin, or blockchain use category and no mining-specific energy cap. A warehouse of mining rigs produces heat, power draw, and continuous noise like any data center, so it is classified as "data processing and hosting" within the Information use and permitted by right in the I-S, I-T, and I-G industrial districts, subject to design review and hazardous-materials review under Section 18.190.220. Cooling and generator noise must meet the Section 18.50.040 limits - Ldn 70 dB(A) beside industry, Leq 50/45 dB(A) beside homes. Home mining is residential accessory use bound by Chapter 9.25 nuisance limits.
No crypto-specific penalties exist. A commercial mining operation outside an industrial district or without design review is a zoning violation, and noise over the Section 18.50.040 limits is abated by the building official.
