There is no "gender-neutral" restroom provision in the plumbing (IPC) or building (IBC) codes. The closest thing that these codes have to a "gender-neutral" restroom is the family or assisted-use toilet room. These are only required for Group A and M occupancies and when the aggregate number of water closets for those occupancy groups is 6 or more.

You did not say where the project is located.
In California, the IBC has been modified such that any single-occupancy restroom (intended for one user at a time) is designated "gender neutral".
But that doesn't affect the number of fixtures; it only affects the labeling on the door of the restroom.

this is in California it is in a county park, it is a two story building with an A3 and a single restroom upstair accessible via an elevator occupant load for the building is 229 they have 5 rest rooms all single usage. one of our inspectors ask (what I thought was a good question for this forum)what would be the required number of toilets based on geneder nutral occupancy.

There seem to be several issues inherent in your question:
1. How many fixtures are required to serve 229 occupants?

a) if it was previously legally permitted with the existing # of fixtures you described, and you are not changing the use or occupancy, then the inspector's question about # of fixtures is irrelevant. It "is what it is". Skip to #3 below.
b) if it is a new building, or a change in occupancy or # of users, then you first look to the CPC to determine # of fixtures for male and # of fixtures for female.​

2. If the answer is 1(b) and you have decided to meet the requirements via 100% single occupancy restrooms, then total up the number of required fixtures (male + female), and that's how many single-occupancy (gender neutral) restrooms you will need.

3. See also https://www.documents.dgs.ca.gov/dsa/bulletins/BU_17-01-01.pdf

4. FYI, if new construction, see also CBC 11B-213.2 exception #4, which says 50% of the cluster of single user restrooms must be accessible.
