(10) Group J — Accessory. — Group J Occupancies shall

include:

Division

1.

—

Private

garage,

carports,

sheds

and

agriculture buildings.

Division 2. — Fences over 1.80 meters high, tanks, and

(b) Other subgroupings or divisions within Groups A to J

may

be

determined

by

the

Secretary.

Any

other

occupancy not mentioned specifically in this Section, or

about which there is any question shall be included in the

Group which it most nearly resembles based on the

existing or proposed life and fire hazard.

SECTION 702. Change in Use . — No change shall be made

in the character of occupancy or use of any building

which would place the building in a different division of

the same group of occupancy or in a different group of

occupancies, unless such building is made to comply

with the requirements of this code for such division or

group of occupancy. The character of occupancy of

existing

buildings

may

be

changed

subject

to

the

approval of the Building Official and the building may be

occupied or purposes set forth in other Groups: Provided,

the new or proposed use is less hazardous, based on life

and fire risk, than the existing use.

SECTION

703.

Mixed

Occupancy .

—

(a)

General

Requirements. — When a building is of mixed occupancy

or used for more than one occupancy, the whole building

shall be subject to the most restrictive requirement

pertaining to any of the type of occupancy found therein

except in the following:

(1) When a one-storey building houses more than one

occupancy, each portion of the building shall conform to

the requirement of the particular occupancy housed

therein and;

(2) Where minor accessory uses do not occupy more than

ten percent of the area of any floor or a building, nor more

than ten percent of the basic area permitted in the

occupancy requirements, in which case, the major use of

the building determine the occupancy classification.

(b)

Forms

of

Occupancy

Separation

—

Occupancy

separations shall be vertical or horizontal or both, or when

necessary, of such other forms as may be required to

afford

a

complete

separation

between

the

various

occupancy divisions in the building.

(c)

Types

of

Occupancy

Separation

—

Occupancy

separation shall be classified as "One-Hour Fire-Resistive",

"Two-Hour Fire Resistive", "Three-Hour Fire-Resistive" and

"Four-Hour Fire-Resistive:

(1) A "One-Hour Fire-Resistive Occupancy Separation"

shall

be

of

not

less

than

one-hour

fire-resistive

construction. All openings in such separation shall be

protected

by

a

fire-assembly

having

a

one-hour

fire-resistive rating.

(2) A "Two-Hour Fire-Resistive Occupancy Separation"

shall

be

of

not

less

than

two-hour

fire-resistive

construction. All openings in such separation shall be

protected

by

a

fire-assembly

having

a

two-hour

fire-resistive rating.

(3) A "Three-Hour Fire-Resistive Occupancy Separation"

shall

be

of

not

less

than

three-hour

fire-resistive

construction.

All

openings

in

walls

forming

such

separation shall be protected by a fire assembly having a

three-hour fire-resistive rating. The total width of all

openings

in

any

three-hour

fire-resistive

occupancy

separation wall in any one-storey shall not exceed 25 per

cent of the length of the wall in that storey and no single

opening shall have an area greater than 10.00 square

meters. All openings in floors forming a "Three-Hour

Fire-Resistive Occupancy Separation" shall be protected

by vertical enclosures extending above and below such

openings. The walls of such vertical enclosures shall be of

not less than two-hour fire-resistive construction, and all

openings therein shall be protected by a fire-assembly

having a three-hour fire-resistive rating.

(4) A "Four-Hour Fire-Resistive Occupancy Separation"

shall have no openings therein and shall be of not less

than four-hour fire resistive construction.

(d) Fire-Rating for Occupancy Separation — Occupancy

Separations

shall

be

provided

between

groups,

subgroupings, or divisions of occupancies. The Secretary

shall promulgate rules and regulations for appropriate

occupancy separations in buildings of mixed occupancy:

Provided,

that,

where

any

occupancy

separation

is

required,

the

minimum

shall

be

a

"One-Hour

Fire-Resistive Occupancy Separation"; and where the

occupancy separation is horizontal, structural member

supporting

the separation shall be protected by an

equivalent fire-resistive construction.

SECTION 704. Location of Property . — (a) General — No

Building shall be constructed unless it adjoins or has

direct access to a public space yard or street on at least

one of its sides.

For the purpose of this Section, the center line of an

adjoining street or alley shall be considered an adjacent

property line.

Eaves over required windows shall not be less than 750

millimeters from the side and rear property lines.

(b) Fire Resistance of Walls .— Exterior walls shall have fire

resistance and opening protection in accordance with the

requirements

set

forth by the Secretary. Projections

beyond the exterior wall shall not exceed beyond a point

one-third the distance from an assumed vertical plane

located where the fire-resistive protection of openings is

first required to the location on property whichever is the

least restrictive. Distance shall be measured at right

angles from the property line. When openings in exterior

walls are required to be protected due to distance from

property line, the sum of the areas of such openings in
