So I'm going 12 rounds with a local fire marshal who wants to define what
temporary parking means, under a drive through canopy. His logic is that he
doesn't know how long a vehicle will be parked. His exact concerns are as
follows: "Our answer was yes do to deliveries made and not knowing how
e was arguing that it didn't require
sprinklers because it was still under the original year of building code as
a remodel. Letter or spirit?

John,
I'm also in Florida and we struggle with the same when it comes to sign and
seal. Project engineer of record doesn't want to sign our shops, AHJ demands
signed shops ... always a point of contention.
In your instance, I agree with you and Buddy that technically you are doing a

We're protecting (4) rows of townhomes per NFPA 13D. Between buildings are
small common areas such as trash storage (132sqft) and mail room (260sqft).
Providing protection in these rooms would come at an additional expense because
the units being protected are fee simple and each has it's own l
I have done a lot of these in many jurisdictions and never protected the
lockers. I have not been asked about it yet.
I do protect the 4x4 or 5x5 lockers that are full height.

Nobody has an informal code interpretation on this? I don't believe we're all
just putting 200 psi on other people's pipe. Anything saved from AFSA, NFSA or
NFPA would be great. Thanks

Does anyone have a release of liability form for when the owner does decide to

We're doing a 200+ sprinkler add and relocate and the new fire marshal has
decided that 200 sprinkler relocates is a lot and that I should put 200 psi on
the existing piping. So we're playing the game of escalation and code
interpretation.

I have a 3-story, 13R building. Type IIB construction. On the "engineered" bid
set, no sprinklers are shown in the covered parking area. This area is inside
the footprint of the first floor, with 2nd floor units being located above the
parking area. There are no garage doors and the parking spac

Where you live does the AHJ have the authority to write his own fire code? In
Florida we would say "that's great that you want that, but no."
13D is two sprinklers. Do you even have 4 sprinklers in a single compartment?
This kind of thing makes me crazy.

I would guess some of you are pretty familiar with fire alarm code as well as
sprinkler code. Our fire alarm division falls under my purview and I really
don't know the first thing about them. They certainly don't seem to follow the
