NFPA 13: Non-combustible Balconies with Gas Outlets

NFPA 13: Non-combustible Balconies with Gas Outlets

NFPA 13: Non-combustible Balconies with Gas Outlets

(OP)

Is sprinkler protection required for an NFPA 13 residential building with non-combustible balconies equipped with gas outlets for BBQ's? If so, where is the requirement stated in the Building Code or NFPA 13?

RE: NFPA 13: Non-combustible Balconies with Gas Outlets

2009 ibc



903.3.1.2.1 Balconies and decks. Sprinkler protection shall be provided for exterior balconies, decks and ground floor patios of dwelling units where the building is of Type V construction, provided there is a roof or deck above. Sidewall sprinklers that are used to protect such areas shall be permitted to be located such that their deflectors are within 1 inch (25 mm) to 6 inches (152 mm) below the structural members and a maximum distance of 14 inches (356 mm) below the deck of the exterior balconies and decks that are constructed of open wood joist construction.

Plus nfpa 13 may kick in if the balcony cover is over four feet

Need to check wording on that

Type V construction is combustible. I'm talking about non-combustible construction.

The answer to this question depends on the jurisdiction's code.

RE: NFPA 13: Non-combustible Balconies with Gas Outlets

from NFPA "13R" 2013 edition



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.


FROM NFPA "13" 2013 edition

8.15.7* Exterior Projections.

8.15.7.1 Unless the requirements of 8.15.7.2, 8.15.7.3, or 8.15.7.4 are met, sprinklers shall be installed under exterior projections exceeding 4 ft (1.2 m) in width.



8.15.7.2* Sprinklers shall be permitted to be omitted where the exterior projections are constructed with materials that are noncombustible, limited-combustible, or fire retardant–treated wood as defined in NFPA 703.



8.15.7.3 Sprinklers shall be permitted to be omitted from below the exterior projections of combustible construction, provided the exposed finish material on the exterior projections are noncombustible, limited-combustible, or fire retardant–treated wood as defined in NFPA 703, and the exterior projections contain only sprinklered concealed spaces or any of the following unsprinklered combustible concealed spaces:


(1)
Combustible concealed spaces filled entirely with noncombustible insulation


(2)
Light or ordinary hazard occupancies where noncombustible or limited-combustible ceilings are directly attached to the bottom of solid wood joists so as to create enclosed joist spaces 160 ft3 (4.5 m3) or less in volume, including space below insulation that is laid directly on top or within the ceiling joists in an otherwise sprinklered attic [see 11.2.3.1.4(4)(d)]


(3)
Concealed spaces over isolated small exterior projections not exceeding 55 ft2 (5.1 m2) in area





8.15.7.4 Sprinklers shall be permitted to be omitted from exterior exit corridors when the exterior walls of the corridor are at least 50 percent open and when the corridor is entirely of noncombustible construction.



8.15.7.5* Sprinklers shall be installed under exterior projections greater than 2 ft (0.6 m) wide over areas where combustibles are stored.

RE: NFPA 13: Non-combustible Balconies with Gas Outlets

(OP)

The local building code is silent on balcony sprinklers as it relates to gas outlets. Some jurisdictions - without documentation in the form of bylaws - are making it a requirement. In my mind there should be something specific requesting it. The local building code has confirmed sprinklers are not required on non-combustible balconies. But like I said, it is silent on the gas outlet variance. The way I see it, if non-combustible balconies are viewed differently when it is equipped with a gas outlet than that should be addressed formally via the building code or AHJ.
