Information sheet
Version: 5
Date: November 2019
Code: IS-115
The following are guidance notes for assessing compliance with the NZ Building Code and Approved
Documents. They include provisions from Acceptable Solutions and NZS 4121:2001. Reference should be
made to these publications for full details, as only a summary of the main items is given below. Refer also
to the Building Act 2004, Section 118 and Schedule 2 of the Act to determine which buildings require
accessible facilities.
Some features are covered by two Acceptable Solutions (e.g. NZBC D1/AS1 and NZS 4121:2001). In such
cases, either may be used as a means of compliance, and both are currently acceptable. However, the
latest version will usually more accurately reflect current thinking and practice.
These guidance notes are subject to ongoing review, and may not cover every requirement. They are
offered on a “no liability” basis.
