NIMBY opposition stalls US datacenter expansion as community concerns mount

New datacenter capacity under construction in primary US markets declined in the second half of 2025, marking the first contraction since 2020 as community opposition increasingly disrupted planning approvals - a dynamic commercial real estate firm CBRE says is reshaping the industry.

According to CBRE's North America Data Center Trends H2 2025 report, the primary-market pipeline shrank to 5,994.4 MW at year-end, down from 6,350.1 MW at the close of 2024. This decline comes despite surging demand for compute power to support AI development, which has driven the overall vacancy rate to a record low of 1.4 percent. Supply still increased by 36 percent year-on-year to 9,432 MW, but the mismatch between demand and available capacity has pushed average monthly rental rates for a 250 to 500-kilowatt (kW) requirement up by 6.5 percent to $195.94 per kW/month - the fourth consecutive annual increase.

Community involvement has emerged as a critical factor in permitting and zoning approvals. In markets like Loudoun County, Virginia, where there is a high concentration of server farms, public sentiment and workforce impacts are having repercussions for development timelines. Local opposition is a growing issue that datacenter developers face. It was a hot topic of discussion at the Datacloud Global Congress in France last year.

Communities fear the effect that facilities might have on energy prices, water supplies, and the environment through noise and pollution from generators. Projects in the US face lengthy delays and even cancellations amid growing grassroots opposition across the states. In response, zoning requirements may mandate the inclusion of green spaces or barriers to reduce visual and noise pollution. Authorities may also impose noise regulations to limit disturbance and protect quality of life for nearby residents.

The tension between datacenter growth and community acceptance reflects broader challenges in balancing technological infrastructure needs with local quality of life concerns. As AI workloads continue to drive demand for massive compute capacity, the physical footprint of these facilities and their resource consumption have become increasingly visible and controversial in local communities.

CBRE notes that at least 36 US states now offer targeted incentives for datacenter developers, including tax exemptions and abatements, which are becoming significant factors in site selection as states dream of AI-driven growth. This is also a bone of contention for communities, with nonprofit Good Jobs First highlighting last year that taxpayers are kept in the dark about the incentives on offer, while states that calculate their returns find they are losing money on the deals.

Other trends listed by CBRE include on-site power generation becoming routine in large-scale datacenter planning, and the shift from AI training to inference workloads driving demand for more regional, distributed facilities closer to end users. That pull is reshaping site strategy and accelerating growth in previously overlooked secondary markets.

CBRE says vacancy rates are likely to remain at all-time lows for the near future due to limited new supply. It does not expect the number of datacenters under construction to increase much this year, with projects stalled at the planning stage due to permitting, zoning, and power procurement challenges.

The datacenter industry now faces a critical juncture where technological demand collides with community resistance. As AI infrastructure requirements continue to grow exponentially, developers must navigate an increasingly complex landscape of local opposition, regulatory requirements, and community expectations. The industry's ability to address these concerns through sustainable design, transparent operations, and genuine community engagement will likely determine the pace and geography of future expansion.

This shift represents more than just a temporary slowdown - it signals a fundamental change in how datacenter infrastructure must be planned and deployed. The days of rapid, unchecked expansion may be giving way to a more deliberate approach that balances technological progress with community well-being and environmental sustainability.
