Rule Changes Salt Lake City, UT local

New commercial buildings limited to 200,000 gallons a day; council signals stricter limits ahead

Today: Council makes water cap permanent

Overview

Updated 10 minutes ago

Salt Lake City's council voted Tuesday to make permanent a rule capping daily water use for new nonresidential buildings at 200,000 gallons. The limit, an emergency measure in place since March, was set to expire Sunday.

The vote comes with the city deep in drought. Two-thirds of Salt Lake County is in extreme condition, precipitation is 4.61 inches below normal, and August brought a record 109°F. Council members called 200,000 gallons a starting point; several want it lower.

Why it matters

With two-thirds of Salt Lake County in extreme drought, this cap sets how much water new businesses can use—and may go lower.

Scenarios

1

Salt Lake City tightens water cap below 200,000 gallons

Possible Resolves by Q1 2027

Discussed by: KSL.com and FOX 13 reporting; Councilwoman Victoria Petro publicly favored stricter limits

Council members, led by Petro, vote to lower the cap for new nonresidential buildings. Planners would set a new threshold, possibly in the 100,000 to 150,000-gallon range suggested at the August hearing. The council could also cut exemptions, closing a "social services" loophole that data centers might exploit. A lower cap would bind more industries, since most already operate under 200,000 gallons.

2

Cap holds at 200,000 gallons, exemptions redefined

Likely Resolves by End of 2026

Discussed by: Council Chairman Alejandro Puy; city planners tasked with clarifying 'social services'

The council keeps the 200,000-gallon limit but revises the exemption definitions. Planners tighten "social services" so data centers and other water-hungry uses can't claim it. The cap stays, but its practical reach widens. This is the path if the council decides lowering the number isn't politically or technically feasible yet.

3

Developer or federal government challenges the cap

Unlikely Resolves by Q2 2027

Discussed by: The ICE detention center dispute; potential takings claims by affected landowners

A landowner, developer, or the federal government files suit arguing the cap is an unlawful taking or exceeds the city's authority. The ICE detention center, which would need 1 to 2 million gallons a day, is the most likely challenger if the federal government revives the project. A court could strike the rule or force the city to pay compensation.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2017-2018

Cape Town 'Day Zero' (2017-2018)

Cape Town came within weeks of turning off municipal taps after a three-year drought dried its reservoirs. The city imposed strict caps of about 50 liters per person per day on residents.

Then

The shutdown never happened; rationing cut the city's water use roughly in half.

Now

The crisis became the global cautionary tale of a modern city nearly running dry, prompting permanent desalination and reuse projects.

Why this matters now

Cape Town's limits were crisis-enforced; Salt Lake City is imposing its cap preemptively, while it still controls the pace and scope.

July 2021

Southern Nevada decorative grass ban (2021)

The Southern Nevada Water Authority voted to ban ornamental grass across the Las Vegas Valley, phasing out an estimated 4,000 acres of turf. The rule targeted Colorado River use as Lake Mead sank toward record lows.

Then

The ban took effect for new homes in 2022 and phases out existing decorative grass over years.

Now

It became a model for Western cities using land-use rules, not just emergency orders, to enforce permanent water conservation.

Why this matters now

Salt Lake City is following the same playbook: a desert city making drought restrictions permanent through building code.
