City Buildings to Open for Public Access

Starting Monday, June 14, Diamond Bar City Hall and the Diamond Center will open for public access during normal operating hours. At this time, City staff will continue wearing face masks or coverings regardless of vaccination status, and visitors are strongly encouraged to do the same.

Alternatives to In-Person Visits to Remain

Individuals looking for a convenient and time-saving alternative to visiting in person can take advantage of expanded service options available through the City’s recently-implemented appointment scheduling system.

The system, available by visiting, allows individuals to schedule a phone, video or in-person appointment for a variety of services ranging from building permits to picnic rentals.  Appointments may be booked as soon as the same day or as far out as 12 months.

Scheduling an appointment in advance of visiting City Hall or the Diamond Bar Center is highly encouraged as walk-ins are welcome but may experience longer wait times, particularly during periods of higher demand.

Examples of Services Available for Appointment Scheduling

  • Simple Permits for Residential Projects
    • air conditioner and water heater replacements, re-roofing, and other miscellaneous electrical, plumbing or mechanical projects
  •  Engineering Services
    • services for grading plans, sewer/storm drains, sewer lateral locations, soils/geotechnical reports, NPDES or storm water quality projects/programs, address changes, lot line adjustments, encroachment activities (construction, placement of a temporary dumpster within public right-of-way), temporary closures of public streets, and street improvements including driveway and sidewalk construction
