Permits & Reservations

Any activity in a Jeffco Open Space park that conflicts with the Park Regulations requires a permit. Such activities include hosting an event, organized activity, or commercial activity. See below to determine the category into which the activity will fall. View the Jeffco Open Space System Map to ensure accurate park location for the activity.

Commercial Activity

A Park Permit may be obtained from Jeffco Open Space to authorize companies or individuals to conduct business within Jeffco Open Space managed lands. A Park Permit provides a group with a non-exclusive license to offer services to park visitors.

An organization is considered a business if it provides goods, services, or activities to the public using Jeffco Open Space managed lands. If an individual receives any form of compensation for what they are providing they are considered to be conducting a business or commercial activity.

Permitted activities must be appropriate to the mission of Jeffco Open Space; complement resource protection, visitor protection and interpretation goals; and not pose any potential for derogation of values or purposes for which Jeffco Open Space was established.
