Emergency repairs to water, gas, or power lines are allowed outside normal hours under the Chapter 18 nuisance exception.
San Bernardino FAQ
Can contractors work on Sunday?
No. Sunday and federal holiday construction is prohibited except under special permit for emergency or critical infrastructure work.
Why do crews start so early?
Inland Empire summer heat often exceeds 100 degrees, so contractors use the 7 AM start to protect workers under Cal/OSHA heat-illness rules.
