Bostonia's Relaxed Approach to Data Centers & Crypto Mining: What's Allowed

Every city handles data centers & crypto mining a little differently. In Bostonia, California, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Data Center Noise Limits

Bostonia has no city noise ordinance. San Diego County Code Sec. 36.404 governs: 50 dBA from 7 a.m. to 10 p.m. and 45 dBA overnight at residential zones, 70 dBA in M52 and M54 industrial zones.

Key details: Code: San Diego County Sec. 36.404. Residential limit: 50 dBA day, 45 night. Industrial M52/M54: 70 dBA anytime. City noise ordinance: None - unincorporated. Measured at: Property line or receiving property.

Noise over the Sec. 36.404 limits is enforced by San Diego County, and a permitted data center also breaches the noise conditions attached to its Major Use Permit.

If you are coming from a city with tighter rules, you will find Bostonia gives residents more flexibility on data center noise limits.

Data Center Zoning & Siting

Bostonia is an unincorporated census-designated place with no city council, no city zoning code, and no city noise ordinance. San Diego County's Zoning Ordinance governs it entirely. A large data center needs a discretionary Major Use Permit in county industrial zones.

Key details: Local government: None - unincorporated CDP. Governing body: San Diego County Board of Supervisors. Use category: Major Impact Services and Utilities. Permit: Major Use Permit, discretionary. Community plan: Lakeside Community Plan area.

Building a data center without the required county Major Use Permit is a county zoning violation, enforced by San Diego County Planning & Development Services through stop-work orders, civil penalties, and abatement.

If you are coming from a city with tighter rules, you will find Bostonia gives residents more flexibility on data center zoning & siting.

The Bottom Line

Compared to many U.S. cities, Bostonia gives residents more room on data centers & crypto mining. 2 of the 2 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Bostonia's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
