Updated Montgomery County Public Pool Guidelines as of 5/12

All spas / hot tubs, spray pools, lazy rivers, and kiddie and wading pools may open May 29, 2021 at the designated occupancy level.

To schedule a pre-opening inspection, contact Licensure & Regulatory Services at 240-777-3986 or call 311.

How to determine occupancy

  • Pools may currently open at 50% total pool capacity.
  • When the Health Officer determines that 60% of County residents have received their first dose of a vaccine, total capacity may increase to 75%.
  • When the Health Officer determines that 50% of the general population has been fully vaccinated, pools may return to total capacity under COMCOR.

Determine pool occupancy by


If the water surface in the shallow area is 1000 sq ft:

  • divide 1000 by 12 to get 83.
  • reduce 83 by 50% to get an occupancy of 42 persons.

If the water surface area in the areas exceeding 5 feet of water depth is 1000 sq ft:

  • divide 1000 by 20 to get 50
  • reduce 50 by 50% to get an occupancy of 25 persons.

The combined total occupancy of the pool and enclosed area would then be 67 persons.

Facilities must also:

Lap lanes

More than one patron per lane is allowed with applicable social distancing.

Indoor pools

Indoor pools should open windows and doors, or use fans or other methods, to increase the circulation of outdoor air as much as possible.  Windows and doors should not be open if doing so poses a safety risk to staff or patrons.

Prepare your Patrons

Face coverings

  • At indoor pools, patrons should wear face coverings, unless swimming or showering.
  • At outdoor pools, patrons not using the pools or water features should wear face coverings per CDC guidance.
  • Patrons should not wear face coverings in the water.

Shared items

  • Discourage patrons from from sharing objects that are difficult to clean, sanitize, or disinfect or that are meant to come in contact with the face (for example, goggles, nose clips, and snorkels).
  • Also discourage them from sharing items such as food, equipment, toys, and supplies with those they don’t live with.

Post signs

Clean and Disinfect

  • Maintain daily cleaning of the facility (floors, toilets, etc.) with soap and water.
  • Maintain daily cleaning log.
  • Train staff on guidelines and product instructions for cleaning and disinfecting.
  • Follow instructions for use and storage on the product label.
  • Disinfection products must be appropriate for the intended use.
  • The pool may need to temporarily close if the CPO on duty must clean and disinfect the pool area.
  • Clean/brush pool tile and wall at the water line to reduce slime and biofilm once a week or more if needed.

Facility operation

  • Maintain chlorine and pH levels per current regulation, including shock or super chlorination as needed.
  • Notify the local health department that the pool will open. Annual operation license is required per current regulation.

COMCOR pool capacity calculation

COMCOR calculates pool capacity like this:

  • Public Pools – After deduction of the 300 square feet for each diving board or platform, one person is allotted for every 20 square feet of Deep Area and one person for every 12 square feet of shallow area.  One additional person is allotted for each diving board or platform.
  • Public Spas – One person is allotted for every 9 square feet of total water area.

COMCOR requires that all pool and enclosure capacities “be conspicuously posted by the owner at the pool.”
