Rental property improvement project across multiple years

We made an improvement on our rental property. It started from 2021 and just finished in 2023 since we had some troubles to get the permit from the city.

 

How should I report this case?

1. Should the city permit fees also go into the capital improvement and be depreciate in 27.5 years?

2. Should we count all expenses related to this project as capital improvement in the tax year 2023 (even though some of them occurred in 2021 and 2022) since the project was not put in service prior to that?
