We have a two-phase project: Phase 1 and Phase 2.

Phase 1 was built and completed many years ago, and it earned LEED certification.
Phase 2 is currently under development and does not have any parking spaces. However, we plan to install EV chargers in Phase 2.

The Question is:

Can we use the existing parking spaces in Phase 1 (which were already used for obtaining LEED certification for Phase 1) to install EV chargers for Phase 2?

We are incredibly grateful for your willingness to share your knowledge.

It sounds like the parking area serves both buildings. I don't see any issue with using the lot to add chargers for Phase 2 and earn the credit. I recommend:

Draw the LEED boundary to exclude all the parking, since it is already part of a certified project and not under construction in Phase 2. Unless some part of Phase 1 is being renovated as part of Phase 2, keep Phase 1 out of your LEED boundary.
Use the total parking count to determine the number of chargers to provide, OR reserve the chargers for the Phase 2 occupants if you are installing a smaller number. You might end up having to decide how many parking spaces "belong" to Phase 2 occupants.
If you want to achieve LTc Reduced Parking Footprint, the phasing shouldn't interfere with that. Again, you could either use the whole lot or decide on a number of spaces to allocate to Phase 2. Just keep everything consistent between the two parking related credits.
