Mechanical Code Requirements

General Information

  • Permits are required before starting work.
  • Permits become void if the work authorized is not commenced within 180 days of permit issuance, or if the work is suspended or abandoned at any time for a period of 180 days or more after the work first begins.
  • All work must comply with the Uniform Mechanical Code and the Mechanical Regulations of the Long Beach Municipal Code.
  • No work is to be covered or energized without first having been inspected and approved by the City.
  • It is recommended that spare electrical capacity be installed initially to allow for the addition of future electrical appliances at minimum costs.
  • California licensed contractors
  • Homeowners of one- or two-family dwellings, accessory buildings, and facilities, if:
    • The owner resides or intends to reside in the dwelling and can show proof of residence
    • The mechanical work is performed by the owner
    • The owner signs a statement that they will not employ an individual who is subject to California workers’ compensation laws

When a permit is issued, the signature and identity of the applicant will be verified — a California Driver’s License, a State of California Identification Card, or other positive identification will meet this requirement.

Contractors working in the City of Long Beach are required to have a Long Beach business license. If a contractor has employees, proof of Workers’ Compensation Insurance must be shown when the permit is issued. Contractors working alone may waive this requirement, but they must show a pocket copy of their State Contractor’s License.
