We are pursuing SSc1 Option 2 Path 10 for a CI project within a CS registered building.

My question is, do I need the Tenant Lease Agreement from the CS project in order to document this credit? The CS base building did not include office fixtures in scope but all the office suites are/will be using fixtures consistent with what the CS scorecard notes. Does LEED require an official document or framework for the credit to be met?
