|SECTION 345B -LOCATION ON PROPERTY|
For an F-7 JLWQ, the fire resistance of the exterior walls and
openings may comply with the provisions for an R-1 Occupancy when
the entire use of an existing building or a portion of an existing
building which is being converted to F-7 JLWQ has been for commercial
or industrial purposes. See Section 503 and Chapter 6. Provided
that the requirements for an R-1 Occupancy does not create a more
hazardous condition to fire and life safety than the existing
condition of the walls and openings. Otherwise, requirements for
an F-1 Occupancy shall apply to commercially/ industrially-oriented
F-7 JLWQ Occupancy.
In general, a residential building is permitted to have openings (i.e. doors and windows) closer to an interior property line that is, a property line shared with another parcel than a commercial building. Typically the distance required in residential is at least 5 feet and in commercial occupancies is at least 10 feet. This provision permitsunder most circumstances live/work buildings to use the less restrictive multi-family residential (R-1) requirements. i.e. five feet. In either case, openings of any kind are not permitted within five feet of an interior property line; windows perpendicular to the property line, however, are not subject to the requirement.
