Acworth's Data Centers & Crypto Mining: The Rules That Matter

Every city handles data centers & crypto mining a little differently. In Acworth, Georgia, there are 3 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.

Crypto Mining Rules

Acworth's Zoning Ordinance sets hard technical standards for cryptocurrency mining operations, server farms, and data centers: an active clean-agent fire suppression system, a 30-minute fire-rated metal containment structure, and a 120-degree Fahrenheit ceiling on containment-space temperature, with entry barred above 90 degrees. The rules sit in Section 73-7.4.3 alongside the use's Heavy Industrial-only siting limit.

Key details: Governing section: § 73-7.4.3(A)-(B). Fire suppression: Active clean-agent system required. Containment fire rating: Resists fire 30 minutes minimum. Max containment temp: 120°F; no work entry above 90°F. Winter heat dump cap: 20% max released outside below 40°F.

Noncompliant fire suppression, containment construction, or heat controls at a data center or mining facility trigger the same Zoning Ordinance enforcement track as any other use violation: a Development Director notice of violation under Section 73-10.2.1, potential stop-work order or special-use-permit revocation under Section 73-10.2.2 through .3, civil penalties up to $1,000.00 per day, and criminal fines up to $1,000.00 or 60 days imprisonment under Section 73-10.2.4.

Data Center Zoning & Siting

Acworth's Use Table permits crypto mining operations, server farms, and data centers in exactly one zoning district, Heavy Industrial (HI), and even there only as a Special Use requiring Mayor and Board of Aldermen approval. Every residential, commercial, office, and Light Industrial column in the table shows the use as flatly not permitted.

Key details: Permitted district: Heavy Industrial (HI) only. Approval type: Special Use, Mayor and Board of Aldermen. Use table section: § 73-4.4. HI district list: § 73-5.11(D)(3), item 3. All other districts: Not permitted (dash in Use Table).

Operating a data center, server farm, or crypto mining facility outside the Heavy Industrial district, or without the required Special Use permit inside it, is an unpermitted use under Section 73-10.2: the Development Director can order the use to cease, withhold a certificate of occupancy, or revoke any permit issued, and the operator faces civil penalties up to $1,000.00 per day and criminal fines up to $1,000.00 or 60 days in jail under Section 73-10.2.4, with each day a separate offense.

This is not one of those rules that cities tend to ignore. Acworth actively enforces its data center zoning & siting requirements.

Data Center Noise Limits

Acworth's Zoning Ordinance bars a cryptocurrency mining operation, server farm, or data center from producing more than 90 decibels measured 25 feet from the outside of its containment structure. The limit sits in the same nuisance-abatement subsection that bars any adverse effect diminishing neighbors' quality of life or raising their costs.

Key details: Noise limit: 90 decibels (dB). Measurement point: 25 feet from containment structure. Governing section: § 73-7.4.3(C)(2). General nuisance standard: No effect diminishing neighbors' quality of life. Enforcement lever: Special Use permit condition, § 73-5.11(D)(3).

A containment structure that tests above 90 dB at 25 feet violates Section 73-7.4.3(C)(2) and is enforced like any other Zoning Ordinance violation under Section 73-10.2: a Development Director notice of violation, potential suspension or revocation of the facility's Special Use permit, civil penalties up to $1,000.00 per day of continued exceedance, and criminal fines up to $1,000.00 or 60 days in jail under Section 73-10.2.4.

The Bottom Line

Acworth's data centers & crypto mining rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Acworth is broadly strict or permissive.

Keep in mind that Acworth can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
