Occupancy and Fixture Count for Pool

[Kevin]

I have a country club pool and I'm looking at IBC and the ISPSC code. I think a country club pool fall under a Class C designation (semi-public related to lodging). I'm thinking that fits the most since you have to be a member. ISPSC has toilet fixture counts for Class A, B and Aquatic Recreation Facilities (splash parks)

IBC 1004 has a pool deck occupant load of 15 sf per person which is translating into over 1000 people. The actual furniture (chaise lounges) accommodates around 150 people.
Counting the pool, I'm looking at about 1500 people, and I'm thinking A-5 is the closest occupancy for fixture counts, but the fixture counts are excessive IMO. Any thoughts on this? I feel like I'm always falling into grey areas with code...

A few questions.

ISPSC has occupancy by water depth and ratio of pool deck to water surface. Water depths are wading or instructional, depth over 5ft and diving.
Not sure what swimming lanes should be. Competitive swim only requires 4ft depth per state guidelines, but I'm using that for the calcs. thoughts?

Since ISPSC code has toilet count requirements for Class A, B and the Splash parks, is it even required for other classes?

Thank you!

When you add up the fixtures don't forget to include the pool.... once for each sex.

Yes, thank you.

ugh. I'm going up with over 20 fixtures for women when I'm using the last row of the assembly fixture count. That can't reflect reality...

I'm looking at about 1500 people

That number seems unreasonably high. There would have to be a parking lot with room for 750 autos. How about showers? When I was a kid we were required to shower before entering the pool and then again before getting dressed.... the last part was a mom rule.

Some states have addressed that, with amendments:

It's interesting that Note F under IPC only refers to PUBLIC pools. ISPSC 2018 Chapter 4 Public Swimming Pools scoping mentions Class C, but there's no mention of Class C when you get to Section 410.1 Toilet Facilities. The local codes consider country clubs as private clubs too.

ISPSC - Chapter 1 Scope and Application
101.2 Scope
The provisions of this code shall apply to the construction, alteration, movement, renovation, replacement, repair and maintenance of aquatic recreation facilities, pools and spas. The pools and spas covered by this code are either permanent or temporary, and shall be only those that are designed and manufactured to be connected to a circulation system and that are intended for swimming, bathing or wading.

ISPSC - Chapter 3 General Compliance
301.1 Scope
The provisions of this chapter shall govern the general design and construction of public and residential pools and spas and related piping, equipment, and materials. Provisions that are unique to a specific type of pool or spa are located in Chapters 4 through 10.

ISPSC - Chapter 4 Public Pools
401.1 Scope
The provisions of this chapter shall apply only to Class A, Class B, Class C, Class E and Class F public swimming pools.

410.1 Toilet Facilities
Class A and B pools shall be provided with toilet facilities having the required number of plumbing fixtures in accordance with the International Building Code or the International Plumbing Code.

I think I'll still follow Section 609 for now, but the lack of any mention of private pools other than residential in ISPSC is confusing.

I did see this under the definitions:

RESIDENTIAL SWIMMING POOL (Residential Pool). A pool intended for use that is accessory to a residential setting and available only to the household and its guests. Other pools shall be considered to be public pools for purposes of this code.

The other confusing thing is that IBC Table 1004.5 does address outdoor pool occupancy loads at 50 gsf per occupant, which is giving me and occupant load of about 140 people inside the pool as opposed to the occupant load per ISPSC which is about 600.


This issue was mentioned in a post here from 2021, so hopefully it will be addressed in the future:
