Alterations of Existing Parks

Requirements for Alterations of Existing Park Utility Systems, Facilities and/or Permanent Buildings

Prior to altering an existing utility system, facility or permanent building within a park, you must obtain a permit to construct from the enforcement agency. Where the Department is the enforcement agency, a Permit to Construct using Form HCD 50 (PDF) must be accompanied with appropriate plans depicting the proposed construction project and appropriate fees.

Plan(s) must be drawn to scale on substantial paper or cloth and be of sufficient clarity to indicate the nature and extent of the construction proposed. Provide detailed plan(s) conforming to the provisions of the California Code of Regulations, Title 25, and all applicable laws, ordinances, rules, and regulations. The first sheet of each set of plans shall give the location of the proposed construction, name and address of the owner and name of the person preparing the plans.

The public may call either our Northern Area Office at (916) 255-2501 or our Southern Area office at (951) 782-4420 to obtain additional information concerning plan and permit requirements.
