The process for making the application is the same as the residential process, but commercial consents are more complex than residential consent applications. All applicants for commercial buildings should make an appointment with a duty building control officer by phoning 03 543 8400.
You'll need to consider some specific issues if you're altering a commercial building, changing its use, or subdividing it.
When an alteration is done to a building, Section 112 of the Building Act 2004 has to be considered.
This section of the Act requires a Building Consent Authority (Tasman District Council) to be satisfied that after the alterations the building will comply, as nearly as is reasonably practicable, with the provisions of the building code that relate to:
For Council to be satisfied that consideration of Section 112 has been undertaken, it requires an evaluation to decide that the extent of the proposed upgrade will be effective.
The evaluation should contain:
The building code clauses that the evaluation should consider:
The evaluation should also look at the benefits and sacrifices so Council can consider what is ‘reasonably practicable.’
Please complete the Building score sheet on page 11 of the guidance document and submit this with your building consent application.
When the use of a building changes, Section 115 of the Building Act 2004 has to be considered.
To determine if the building is a change of use, see Sections 5, 6 and Schedule 2 of Building Regulations 2005 (Specified Systems, Change the Use, and Earthquake-prone Buildings) for use of all or parts of the building. If part of the building changes use then the building needs to be considered under Section 115. Section 115 is in the Act to ensure the current building stock is being upgraded toward the current provisions of the building code.
An owner of a building must not change the use of the building:
For the Council Building Consent Authority to be satisfied consideration of Section 115 has been undertaken we require an evaluation to decide that the extent of the proposed upgrade will be effective. The evaluation should contain:
The evaluation should also look at the benefits and sacrifices so we can consider what is ‘reasonably practicable’.
If you want to subdivide an existing commercial building, you must consider Section 116a of the Building Act 2004.
As a Territorial Authority, Council must not issue a certificate unless we are satisfied that the building will comply, as nearly as is reasonably practicable, with every provision of the Building Code that relates to:
The building must also continue to comply with the other provisions of the Building Code to at least the same extent as before the subdivision application was made. This often requires a building consent application to undertake any necessary work to upgrade a building.
Note that since 2012 some consents require referral to Fire and Emergency New Zealand.
Where a building with a specified intended life is issued with a building consent that is subject to the condition that the building be altered before the end of its life, an 'extension of life' can be obtained.
An owner of a building must give written notice to the council if it proposes extending the life of a building.
