This project is located on Regent Street, which is a very famous, historical shopping street in London. Due to the heritage nature, the design guidelines for the facade of all stores along this street are very strict. For this reason, the landlord is unable to install no smoking signage at the entrance.
In addition, smoking is prohibited indoors across the whole of the UK too.

I’ve found LEED Interpretation ID #10435 however this does not help as the landlord has refused to install signage at the tenant entrance.

With this in mind, can an exception be granted here and if so, what documentation would be adequate to demonstrate credit compliance?
