SECTION 345B -LOCATION ON PROPERTY
Code Plain English

345B.1 General.

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.
Exception: When a building complies with the allowable area requirements as for an R-1 occupancy and the F-7 Occupancy is fire-sprinklered the fire resistance of the exterior walls and openings may comply with the provisions for an R-1 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 permits–under 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.
