Permits & Authorization
City encroachment / public works permit
Most cities require an encroachment or public works permit for work in city streets and sidewalks, issued by the city's public works or engineering department. The permit types, hours, notice, fees, and conditions vary from city to city and must be confirmed with the specific city — they are not stated here.
How to Verify Requirements
- Confirm which city the work is in, and that the road is a city street rather than a county road or state highway.
- Find the city's public works or engineering department and confirm its current permit types, application process, and conditions.
- Confirm device and setup standards against the current California MUTCD and the city's standard plans.
