Rural, and Suburban Areas (2017).
AHJ Authority Having Jurisdiction.
Adjacent Ground Elevation The reference plane representing the average elevation of the finished ground
level measured at a distance of 10 ft (3 m) from all exterior walls of the building.
Built-Out Area Those portions of a development that have been populated to planned
capacity with structures.
Building A structure, usually enclosed by walls and a roof, constructed to provide
support or shelter for an intended occupancy.
Combustible A material that, in the form in which it is used and under the conditions
anticipated, will ignite and burn; a material that does not meet the definition of
noncombustible or limited-combustible.
Fire Flow The flow rate of a water supply, measured at 20 psi (138 kPa) residual pressure,
that is available for fire fighting.
Fire Hazard Any situation, process, material, or condition that, on the basis of applicable
data, can cause a fire or explosion or that can provide a ready fuel supply to
augment the spread or intensity of a fire or explosion, all of which pose a threat
to life or property.
Fire Protection System Any fire alarm device or system or fire-extinguishing device or system, or
combination thereof, that is designed and installed for detecting, controlling,
or extinguishing a fire or otherwise alerting occupants, or the fire department,
or both, that a fire has occurred.
Land Development The change of use of a parcel of land or contiguous parcels of land controlled
by a single landowner or by a group of landowners with or without a common
agreement to control the land so as to provide the buildings and infrastructure
for residential and/or commercial purposes.
Land Use The type or degree of activity occurring or intended to occur on a piece of
land.
Means of Access The method by which vehicles travel to or from structures, including but not
limited to roadways, driveways, fire lanes, and parking lots.

Rural Those areas that are not unsettled wilderness or uninhabitable territory but are
sparsely populated with densities below 500 persons per square mile.
Suburb or Suburban Those moderately inhabited areas with population densities of at least 500
persons per square mile but less than 1000 persons per square mile.
Building Access Requirement Means of access shall be provided to all buildings more than 400 ft2 (37 m2) in
ground floor area and to public occupancies with structural components.
Gate Location Requirement Any gates shall not be located closer than 30 ft (9.144 m) from an intersection
and shall open in the direction of emergency vehicle travel unless other
provisions are made for safe personnel operation.
Gate Width Requirement The clear opening through gates shall have a usable width at least 2 ft (0.6 m)
wider than the means of access it controls.
Mandatory Requirement 'Shall' indicates a mandatory requirement.
Recommendation 'Should' indicates a recommendation or that which is advised but not required.
Conflict Resolution When a conflict between a general requirement and a specific requirement
occurs, the specific requirement shall apply.
Less Restrictive Requirement When a requirement in a referenced document is less restrictive than this
standard, the requirements of this standard shall apply.
Access routes in mixed areas The minimum number of access routes shall be determined by calculating five
parking spaces for each dwelling unit, adding that number to the parking
spaces count for the nonresidential area, and using Table 5.1.4.1(b).
Minimum roadway width Roadways shall have a minimum clear width of 12 ft (3.7 m) for each lane of
travel, excluding shoulders and parking.
Vertical clearance requirement At least 13 ft 6 in. (4.2 m) nominal vertical clearance shall be provided and
maintained over the full width of the roadway.
Minimum turn radius Turns in roadways shall be constructed with a minimum radius of 60 ft (18.2 m)
to the outside of the turn.
