Owen:

Weren’t you the one complaining that a couple hundred dollar flow test was 
causing significant problems. 

Now you want to make a detached garage in a 13D system to have NFPA 13 
densities. Wouldn’t that require a full flow test there?

That meter upsize is likely far more expensive than the flow test. 

13D is about making the systems cost effective to get them into homes with less 
resistance. 

Pure 13D says no sprinklers in the garage when it is attached. By making it 
detached, there would be a more solid argument for not putting sprinklers in 
it. 

To the original question: If you have to protect the detached garage, I would 
follow the requirements of 13D as modified by the local fire code when 
applicable.
