Summary

Renton has no standalone data-center use category; RMC 4-11-040(D) folds data centers into "Warehousing" under RMC 4-11-230(D). The zoning use table permits Warehousing, and therefore data centers, only in the Light, Medium and Heavy Industrial zones through an Administrative Conditional Use Permit, and prohibits it everywhere else in the city.

D. WAREHOUSING: A use located wholly within a building engaged in the storage of goods and/or materials characterized by infrequent pick-up and delivery. The definition includes data centers, but excludes bulk storage, hazardous material storage, self-service storage, warehousing and distribution, fulfillment centers, wholesale retail, and vehicle storage.

Full Breakdown

RMC 4-11-040(D) defines DATA CENTER as "a facility used primarily for off-site storage of computer systems and associated components including applications and secure data" that "may include maintenance areas and a small office," then directs readers to "RMC 4-11-230, WAREHOUSING" for its zoning treatment. " In Renton's Zoning Use Table (RMC 4-2-060), Warehousing carries an "AD" marker, Administrative Conditional Use Permit, only in the Light Industrial (IL), Medium Industrial (IM) and Heavy Industrial (IH) columns; every residential zone (RC, R-1 through R-10, RMH, RMF, RMF-2) and every commercial zone (CN, CV, CA, CD, CO, COR, UC-1, UC-2) carries no permit symbol at all for Warehousing, meaning the use, and by extension a data center, is prohibited there outright.

" Because data centers are legally warehousing, a Renton data center is confined to the three industrial zones, subject to administrative discretionary review, the 200,000-square-foot cap, and the two-year trip-monitoring reporting duty.

Violations & Fines

Siting a data center outside the Light, Medium or Heavy Industrial zones, or without the required Administrative Conditional Use Permit, is a misdemeanor under RMC 1-3-1(A)(2) for using land in violation of an approved permit. The City may instead charge a class 1 civil infraction of up to $250 under RMC 1-3-1(D), with each day of continued noncompliance a separate offense under RMC 1-3-1(E), and may suspend or revoke the permit under RMC 1-3-1(F).

Frequently Asked Questions

Can a data center locate in a Renton commercial zone?

No. Renton's zoning use table lists no permit symbol for Warehousing, the category that legally includes data centers under RMC 4-11-040(D) and 4-11-230(D), in any commercial or residential zone. It carries an Administrative Conditional Use Permit marker only in the Light, Medium and Heavy Industrial zones.

Is there a size limit on a Renton data center?

Yes. Because data centers fall under Warehousing, Condition 11 in RMC 4-2-080 caps warehousing facilities at two hundred thousand (200,000) square feet of gross floor area and requires the operator to monitor and report vehicle trip counts to the Administrator for at least two years after operations begin.

Does building a Renton data center require a public hearing?

Not automatically. The zoning use table marks Warehousing "AD" in the industrial zones, meaning City staff review it as an Administrative Conditional Use Permit rather than sending it to the Hearing Examiner, though Condition 11's size cap and trip-monitoring duty still apply.

What happens if a data center is built without the required permit?

Using land in violation of an approved permit is a misdemeanor under RMC 1-3-1(A)(2). The City can pursue a civil infraction up to $250 under RMC 1-3-1(D), count each day of noncompliance as a separate offense under RMC 1-3-1(E), and suspend or revoke any permit already issued under RMC 1-3-1(F).
