Window size regulations coming

The Planning Department will begin to enforce the required size of at least one window in sleeping rooms beginning 1 September

The move is in accordance with the Cayman Islands Building Code.

The code requires that at least one window in a sleeping room can be used as an emergency exit, explains the department’s Chief Building Control Officer Emerson Piercy, state a press release.

Therefore, section 1005.4 of the code sets the measurements for the minimum amount of space through which a person can climb out of this window. In the code, this is called the minimum net-clear opening.

‘For upper-story windows, the revised regulations require a minimum net-clear opening of 20 inches in width, 24 inches in height and 5.7 square feet in total area,’ Mr. Piercy said. ‘Meanwhile, at least one window in a ground-floor sleeping room must have a minimum net-clear opening of 5 square feet.’

After 1 September 2006, all plans must specify the larger net-clear openings.

‘To comply with the code, contractors will be expected to meet all of the new requirements,’ Mr. Piercy said, noting that several commonly used windows no longer meet the requirements.

To ensure that the window is the correct size, a sheet from the window manufacturer’s catalogue, showing the actual dimensioned clear opening for each type of exit window, should be provided with building-permit applications submitted after 1 September. Copies of such sheets can be requested from window suppliers.

The Cayman Islands Building Code is a revision of the 1994 version and consequently contains several amendments. To minimise the difficulties and hassle that industry personnel may face in adopting these revisions, the CI Planning Department has been phasing in the new sections, one at a time, over the past few years.

Section 1005.4 is just the most recent of the amendments to be phased in.
