I am replacing a poured concrete stair to eliminate tripping hazards/spalls. The existing stair has 3 risers, each about 6" high, and there is sloped grass on both sides of the stair. The new stair will be replaced identical to the existing. Will the new "replaced" stair require handrails? The site is an apartment complex and the stair connects the public sidewalk with a concrete stoop that leads to one apartment unit only. It is not ADA. Pennsylvania, R-2 Use, 2009 codes. Thanks in advance!
