What happened
San José's draft standards define Large Load Data Centers and Large Load Research and Development Facilities as 20 MW or greater. Proposals include City Council hearing of land-use and CEQA appeals above 20 MW; cooling with 100% recycled water or low-water closed-loop or air-cooled systems, banning potable open-loop cooling; 100% carbon-neutral electricity; EPA Tier 4 generators with testing limited to 25 hours a year; annual sewer-discharge and noise monitoring; third-party verification of actual energy and water use against environmental-clearance assumptions; a 1,500-foot notification radius; and an anticipated $4-5 per square foot housing linkage fee and about $50,000 per MW reliability fee, both under study. The Planning Commission is due to review them Nov 18, with council readings Dec 8 and 15; they would apply to applications still under review when they take effect.
Why it matters
Newly relevant because the council's Oct 20 Holger Way decision concerned an NVIDIA-leased R&D building permitted at 20 MW, the threshold the draft uses, and because the standards cover R&D facilities, not only data centers. A detailed local template for any city, county or university district reviewing GPU facilities.
Evidence and measured results
Official city release describing draft standards subject to change; no adopted text, no enforcement record, fees still under study. Retrieved via a fetch tool after curl received HTTP 403.
Limitations and uncertainty
Draft only; a critic quoted in separate local coverage says the standards rely on words like 'encourage' and 'monitor'; generator limits do not apply during outages.
Put this evidence to work
Lighthouse Advisory interpretation, grounded in this source. Enriched 2026-10-24; this does not change the original publication date. Each role follows the same checklist so takeaways compare across sources.
Sales
Role takeaway
- Customer problem
- Hosts of large GPU facilities face new local conditions on water, power, generators and audits.
- Stakeholders
- City planning and sustainability staff
- Facility owners and tenants
- University facilities offices
- Utilities
- Community groups
- Discovery questions
- Does the planned facility reach 20 MW?
- Can it use recycled water or closed-loop cooling?
- Is carbon-neutral supply available through the local clean-energy provider?
- Who will produce annual reports?
- Value hypothesis
- Interpretation: designing for these standards early could avoid redesign and appeal delays; no adopted rules yet.
- Potential engagement
- Compliance readiness review of a planned GPU facility against San José's draft standards.
- Unsupported claims
- Standards are adopted
- Fees are final
- Standards will end community opposition
Pre-sales engineering
Role takeaway
- Fit
- GPU facilities near or above 20 MW in San José or cities adopting similar rules.
- Architecture and integration
- Cooling, power supply, backup generation and metering designed to meet draft requirements and third-party verification.
- Prerequisites
- Recycled water access or low-water cooling design
- Carbon-neutral electricity supply
- Tier 4 generators
- Energy and water metering
- Constraints
- Draft text may change
- Generator limits exclude outages
- Fees under study
- Security
- Not addressed by the source.
- Proof of value
- Model annual water loss under chosen cooling
- Demonstrate metering accuracy for third-party verification
- Test generator schedule against the 25-hour cap
Delivery
Role takeaway
- Work
- Build compliance reporting and metering into commissioning and operations.
- Dependencies
- Final ordinance text
- Utility and water-recycling availability
- Third-party verifier
- Ownership
- Facility operator's environmental compliance lead.
- Skills and adoption
- Operations staff need reporting and audit-preparation routines.
- Governance checkpoints
- Planning Commission review (Nov 18)
- Council readings (Dec 8 and Dec 15)
- Annual reports and verification
- Acceptance criteria
- Proposed: annual energy and water use within environmental-clearance assumptions
- Proposed: no potable open-loop cooling
- Proposed: generator testing logged under 25 hours per year
- Risks
- Rules tightened before adoption
- Verification findings requiring retrofits
- Fee levels higher than budgeted
Implementation considerations
Lighthouse Advisory interpretation across the operating dimensions a public-sector buyer must settle before this evidence becomes a design. Each note answers the question under its heading for this specific source.
Architecture and integration
What must connect, and where does the AI sit in the workflow?
Pushes designs toward recycled-water or closed-loop/air cooling and clean-energy supply; requires metering sufficient for third-party verification.
Governance
Who approves, reviews and stays accountable for outcomes?
Moves large-project appeals to the council, adds inspection and enforcement authority, expands public notice, and applies to pending applications once effective.
Security and privacy
What data, permissions and controls need testing?
Not addressed.
Accessibility and workforce
Who is affected, and what skills or accommodations follow?
Includes prevailing wage and skilled-workforce requirements and encourages local hiring and apprenticeships.
Procurement
What should contracts, pricing and exit terms secure?
Fees (linkage, reliability) and labor standards add cost that hosts must budget; the city seeks use-tax attribution on equipment purchases.
Operating model
Which teams own the service once it runs?
Operators would carry annual reporting and third-party verification duties for the life of the facility.
