Rules and Regulations

OSMP facilities are patrolled by local law enforcement agencies. All applicable rules and regulations, including state statutes and city ordinances, are enforced.

  • The applicant is prohibited from raising funds, charging admission, or providing private training for pay unless combined with an OSMP Commercial Use Permit.
  • Glass containers are prohibited in any areas of OSMP, pursuant to section 8-3-9, B.R.C. 1981 (wine glasses, champagne bottles and vases included). The use and breaking of glass for religious ceremonies will be permitted only if done on a sturdy tarp and all glass is contained and removed.

If it is determined that noise is disturbing other visitors, the persons responsible will be asked to lower the noise and/or terminate the event and may be charged an additional fee for the services of the noise control officer(s) and will be responsible for any violations of city regulations.
  • Destruction, damage, or removal of any vegetation or defacement of property is prohibited. Permit holders will be charged for the cost of repairs, and any violator of city regulations will be prosecuted.
  • Loading and unloading of vehicles must be done from designated parking lot areas. Vehicles are prohibited from idling. 
  • No person shall start or maintain, or cause to be started or maintained, any fire on any public property, park, parkway recreation area, open space, street, or public way, unless confined within a fireplace or grill permanently erected by the city for such purpose. No person shall place, erect, build, or construct a fireplace, stove, or other fire container in any public property, park, parkway, recreation area, open space, or public way, except pursuant to a written permit from the city manager, pursuant to section 5-4-10, B.R.C. 1981.
  • All firewood and charcoal to be used in a permanent fireplace or grill on site must be furnished by the person(s) reserving the facility.

Fireplaces and associated grills must be left in a clean condition, and fires must be fully extinguished and cold before leaving the area. Collecting wood or creating ground fires is strictly prohibited.
  • Please note: Fire bans may be in effect at any time that prohibit fires or ignition sources of any type, including what has been allowed in a permit. Check in advance of the event for any fire bans.
  • Facilities must be left in a clean and orderly condition. Tables and other equipment must be replaced in their original location. Additional chairs, tables or equipment will not be furnished by OSMP. For enclosed facilities, windows and doors must be closed and locked.

Arches used in religious ceremonies will need to be held by participants.

Rental Time Blocks

The three primary rental periods are three-hour time blocks, beginning at 10 a.m. and ending at 9 p.m. Time blocks are separated by a mandatory hour between reservations, which is not reservable and is designated for the coming and going of parties. There are also early morning, one-hour time blocks beginning at 6 a.m. and ending at 9 a.m. Early morning time blocks do not have the non-reservable hour in between reservations.

One-hour time blocks

  • 6 a.m. to 7 a.m.
  • 7 a.m. to 8 a.m.
  • 8 a.m. to 9 a.m.

Three-hour time blocks

  • 10 a.m. to 1 p.m.
  • 2 p.m. to 5 p.m.
  • 6 p.m. to 9 p.m.

Alcohol Permits

Alcohol permits are required at all OSMP shelters/facilities for groups of 15 or more people when alcohol is being consumed. Alcohol permits will be granted to City of Boulder residents only and proof of residency will be required before an alcohol permit will be issued. Learn more about the requirements and conditions for Alcohol Permits.

Alcohol permits are issued pursuant to chapter 5-7, B.R.C. and all permit holders must comply with all state and local alcohol laws.


Posting any type of sign on OSMP property is prohibited. The regulation states, "Under no circumstances are signs, balloons, or any other items to be nailed, pinned, stapled or otherwise attached to any tree, park sign, facility, and/or along the roadways." Signs will be removed by OSMP personnel. OSMP suggests the following:

  • Provide guests with a good map when mailing the invitations.
  • Post members of the party at critical junctions in the road to direct incoming guests.


Dogs are allowed at the facilities as long as they are in compliance with the current dog regulations. The Stone and Wood Shelters require dogs to be on leash at all times. The Green Mountain Lodge, Halfway House, Sunrise Amphitheater, and Bluebell Shelter allow dogs as long as they are on leash or if guardians are participants of the Voice and Sight Control Program.

Fire Bans

It is the responsibility of all permit holders to check in advance of their event for any fire bans. Fire bans may be in effect at any time that prohibit fires or ignition sources of any type, including what has been allowed in a permit.


If there are no reservations before the scheduled event, permit holders may use the facility on a first-come, first-served basis to decorate. The hour between time blocks is meant for the coming and going of parties. Be aware that there may be overlap between parties. Under no circumstances are signs, balloons or any other items to be nailed, pinned, stapled, or otherwise attached to any tree, park sign, facility and/or along the roadways. No rice, confetti, birdseed or straw shall be used at events. Doing so is considered littering. Glass and open flames are prohibited, including unity candles.


Please be aware that the only restrooms available are pit latrines. There are no other structures (changing rooms) available for event parties to use in preparation for events.

Advance Facility Rentals

You can reserve a shelter or facility up to two years in advance of the event date.


You may bring a battery-operated portable player or have acoustic music. Use of live bands and amplification is restricted. Applicants must comply with noise ordinance as defined in Chapter 5-9, B.R.C. 1981 and section 8-3-13, B.R.C 1981. There is no electricity at any of the facilities. Tents, nets and canopies are prohibited, so please advise musicians to plan accordingly.
