Parma, OH Building Safety: Door Locking Hardware (2026)

40(d) sets Parma's residential locking-hardware standard as part of its Security Safeguards for Dwellings chapter. Paragraph (1) requires every outside side-mounted swing door to have two mortised locking devices: one may be a traditional spring-loaded dead latch, but the second must be a dead bolt without spring action, actuated by a key from outside and a knob or thumb turn from inside; if the door has an integrated glass panel, the dead bolt must have double-cylinder actuation requiring a key on both sides. Paragraph (2) requires Dutch or horizontally divided doors to have a strike plate mortised into the lower door and a dead bolt mortised into the upper door so the two segments lock together.

Paragraph (3) requires sliding glass doors to carry two locks, a standard drop lock at the closing edge plus a separate dead bolt at the top or base strong enough to secure the door even if the drop lock is defeated. Paragraph (4) sets a distinct, stricter rule for rental housing: every entryway door into a rental unit must have at least two mortised locking devices, one of which is a dead bolt with a throw of at least one inch, and all such doors must be readily openable from inside without a key.

40 standards for doorjambs (subsection (c), requiring metal jambs with mortised strike plates), viewing devices (subsection (e), a 175-degree peephole on doors without glass), and security lighting (subsection (f), at least one 100-watt exterior fixture at every entryway except an attached-garage door).
