    How many stories before elevator required?

    I am thinking that a three story building does not require an elevator but a four story office building would require an elevator. I've searched IBC and NFPA but can not seem to find anything that would require an elevator. Once I introduce an elevator, there are several requirements. But nothing to say that I must have an elevator - regardless of height and building area.

    Thanks

    Check Section 1007.2.1.

    Accessibility.

    1007.2.1 is the section but you also need to know the proposed tenants. ADA will kick in on the type of tenants. I think the ICC/ANSI A117.1 also addresses type of tenants.

    Basically 1007.2.1 will be a 5-story building if the level of Exit discharge is the 1st floor (ground). The thing to remember its 4 or more stories above or below a level of exit discharge. The level of exit discharge is a separate story.

    ACCESSIBLE ROUTE. A continuous, unobstructed path that complies with this chapter.
    That can be a ramp or an elevator

    1104.4 Multilevel buildings and facilities.
    At least one accessible route shall connect each accessible level, including mezzanines, in multilevel buildings and facilities.
    Exceptions:
    1. An accessible route is not required to stories and mezzanines above and below accessible levels that have an aggregate area of not more than 3,000 square feet (278.7 m2). This exception shall not apply to:1.1. Multiple tenant facilities of Group M occupancies containing five or more tenant spaces;
    1.2. Levels containing offices of health care providers (Group B or I); or
    1.3. Passenger transportation facilities and airports (Group A-3 or B).
    2. In Group A, I, R and S occupancies, levels that do not contain accessible elements or other spaces required by Section 1107 or 1108 are not required to be served by an accessible route from an accessible level.
    3. In air traffic control towers, an accessible route is not required to serve the cab and the floor immediately below the cab.
    4. Where a two-story building or facility has one story with an occupant load of five or fewer persons that does not contain public use space, that story shall not be required to be connected by an accessible route to the story above or below.

    Our state has accessibility regs that trump ICC. Those regs exempt buildings "under three stories", "unless the building is a shopping center". Why they couldn't just say three or more stories I don't know.

    If it's a healthcare provider, ADAAG 1994 requires an elevator as well.

    After taking into consideration IBC 1007.2.1 and realizing that not all floors are required to be accessible, then I look at IBC 1104.4 to see the long list of exceptions.

    Theoretically, I can design a 20 story sprinkled building with my elevator going directly from ground floor to fourth floor and providing access to no other floor.

    Floor 20: Group "R2" Penthouse apartment (no elevator)
    Floor 19: Group "S1" Mechanical & Storage
    Floor 18: Group "R2" Residential apartments
    Floor 17: Group "R2" Residential apartments
    Floor 16: Group "R2" Residential apartments
    Floor 15: Group "R2" Residential apartments
    Floor 14: Group "R2" Residential apartments
    Floor 13: Group "R2" Residential apartments
    Floor 12: Group "R2" Residential apartments
    Floor 11: Group "R2" Residential apartments
    Floor 10: Group "R2" Residential apartments
    Floor 9: Group "R2" Residential apartments
    Floor 8: Group "R2" Residential apartments
    Floor 7: Group "R2" Residential apartments
    Floor 6: Group "R2" Residential apartments
    Floor 5: Group "R2" Residential apartments (no elevator)
    Floor 4: Group "A2" Restaurant with elevator access
    Floor 3: Group "M" Retail with five tenants (no elevator)
    Floor 2: Group "M" Retail with five tenants (no elevator)
    Floor 1: Group "I2" Health care provider


    My tenant living on the 20th floor would need to be very strong and healthy!

    Re: How many stories before elevator required?

    Well, the ICC/ANSI A117.1 and Section 1107.6.2.1.1 requires 2% (If more that 20 units total per structure) of the residential units to meet Type A accessibility. That means unless you can get all of the necessary units on the ground floor on an accessible route you will need an elevator.

    This creates another issue. Emergency power is required for elevators used for emergency egress.

    Section 3003.

    Typically structures greater that 3 stories shall have elevators with emergency power.

    At least one elevator w/ standby power is required for buildings with a floor 75 feet above lowest fire equipment access (high rise 403.9). Granted, it is for fire department use, but, the tenants could pay extra rent to use it. :P
