Making alterations to an existing building
WHAT is a change of use of an existing building?
Where an owner is proposing to change the use of an existing building (or part of a building) there are some circumstances, where an owner must give notice in writing to Council of their intention.
A change of use occurs when a building's (or part of a building's) use, as defined in the regulations, changes and the new use has more onerous or additional Building Code requirements than the old use. The additional or more onerous requirements will usually mean that the fire hazard or the risk to life has increased in the building's new use.
Building uses are grouped into four broad categories;
- Crowd activities
- Sleeping activities
- Working activities
- Business or storage activities and intermittent activities.
These four broad categories each have a number of uses and overall there are a total of 15 different uses. Definitions and examples of the uses can be found at www.legislation.got.nz.
Council can be notified of a change of use to a building or part of a building either through the following:
- A building consent application, where the work triggers the requirement to obtain a building consent; or
- Written notification, when a building consent is not required, the notification will need to include documentation outlining compliance with Section 115 of the Building Act and the appropriate clauses of the Building Code.
If your proposed project includes the change of use of a building or part of a building, Council recommends you seek professional advice and organise a pre-application meeting with a member of our building control team prior to submitting an application or notification.
Building Code Compliance requirements for subdivision
It is Council’s role to ensure
individually-owned, multi-unit developments meet minimum Building Code compliance levels. This is to ensure that the people using them can do so
safely and keep them healthy.
This applies to all unit titles,
cross-leases and company lease subdivisions.
If you are proposing to subdivide a
building or part of a building you will need to provide Council with
information on how the building complies. This information can be
provided through a compliance report and a compliance statement. The
report and the statement must demonstrate that the legal requirements of the
Building Act are met and that the subdivided building complies as closely as
possible with the Building Code.
The evidence for compliance may
require you to engage professional consultants to prepare information such as
means of escape from fire, access and facilities for people with disabilities,
surface water, internal moisture, structural stability during a fire and fire
protection to other property etc.
If your proposed project includes the
subdivision of a building or part of a building, Council recommends you seek
professional advice and we would recommend a pre-lodgement meeting with a
member of our building control team prior to lodging an application or
Extending the life of a building
Some buildings have a specified
intended lifespan, either due to Code Compliance inadequacies or because they
were constructed to be temporary buildings. When a building consent is issued
on a building like this, it is subject to the condition that it be altered,
demolished or removed before the end of its life.
However, Council can approve an ‘extension of life’ if we are
satisfied the building can continue to perform for a longer period.
If you would like to extend the life of a building you will need to
provide us with written notice.
We recommend you seek professional
advice and organise a pre-lodgement meeting with a member of our building
control team prior to submitting a notification.
