Code: The building code in effect at the time of the house construction would have been the l955Uniform Building Codes (UBC)(attached). The minimum headroom cleararce in 1955 was 6'6^ Research shows the minimum requirement for stairway headroom clearance did not increase to6'8^ until the early 90's and rernains that today. The City of Louisville is currently urider the adopted 2012 lnternatiorial Residential Code (IRC). Ir your Appeal Application you quoted R311.7.2 and R102.7 This requirement, R311.7.2 is for new construction and is more restrictive than tbe requirement iri 1950 wben tbe horne was built. Issue: The existing horne has a stairway leading to the basement. Attbe bottom ofthe stairway is a structural existing steel girder witb a head cleararice height oF E (72"). The applicant bas submitted a permit to remodel/finisb the basernent. The BuFldirig Official will not approve ari existing 6 stairway head height. Summary As stated in the home history portion of this report, the home at 1610 Circle Drive was built in 1960. The miriimum building code stairway headroam clear.ance requirement in 1960 when the home was constructed was 6'6" (attached). That said, along with our records showing no permits for the basement area, I will assume the 6' stairway headroom clearance violation has always been there from the beginning ofthe homes existence. |nyour application, you have provided (1)section and (1) suhsection to the (IRC)International Residential Code which] have addressed above. As for any IBC references in your Appeals App|[catinn'thep|annaverereviewedandthepermitwasissuedumderthe|RC.|fvvevvereto review and issue the permit underthe adopted IBC, based ori IBC 903.Z.8you would be required to provide a sprinkler system in both the proposed basement finish project and the existing house and there are no exceptions. It is for that reason we review one and two family residential applicatioris urrderthe IRC as there is ari exceptiori to tlie residential requirement for existing structures (R3I3.2). Final Decision: The minimum allowable stairway headroom clearance allowed for this existing structure is 6'6" based nn20lZIRC RI027/l02II(shown be|ow)and the l955U0C3D05(U (attached)
