The 2009 edition of the IBC added the balcony must have a roof or deck
above regarding required sprinkler protection. Nothing regarding
whether the overhang on the top floor is a driver. Additionally, the
2013 edition of NFOA 13R finally acknowledge the supremacy of the code
over standards in driving such matters and added the below text.
6.6.5* Except as provided for in 6.6.5.1, sprinklers shall not be
required in any porches, balconies, corridors, carports, porte
cocheres, and stairs that are open and attached.
6.6.5.1 Where a roof or deck is provided above, sprinklers shall be
installed to protect attached exterior balconies, attached exterior
decks, and ground floor patios serving dwelling units in buildings of
Construction Type V.
6.6.5.1.1 Where sidewall sprinklers are installed beneath decks or
balconies constructed with open wood joists, sprinklers shall be
permitted to be installed with deflectors not less than 1 in. (25 mm)
or more than 6 in. (152 mm) below the structural members, provided
that the deflector is not more than 14 in. (356 mm) below the
underside surface of the deck. systems, or other reliable means
capable of maintaining a minimum temperature between 40°F and 120°F
(4°C and 48.9°C).

The Connecticut Fire Safety Code (at least the part that is based on
the IFC) includes a requirement that exterior balconies and patios
be sprinkelred in 13R occupancies. However, this is being
interpreted that they have to be protected regardless if there is
any structure above or not. Consequently, we have to install
sidewall sprinklers under 9" door moldings because they open on to a
patio or deck (just got a plan rejected for this). This make no
sense to me because they would most likely never activate, but this
is being enforced as the law. Anybody else run into this?
