LET’S GETIT RIGHT!

This is intended as a guide only to help you prepare for inspections by Nelson City Council Building Inspectors.

Page 2 Nelson City Council • INSPECTION BOOKINGS: 03 546 0334 • [email protected]

INTRODUCTIONThis information will be updated when requirements change so please ensure you have the most recent version.

The latest version is available for download from the Council website (nelson.govt.nz).

Each building site is unique and will have its own individual requirements so it’s important you read the consented documents and pay particular attention to any conditions or endorsements and your site inspection schedule.

Prior to starting any building work you need to ensure the consent has been issued and paid for and your consented documents are printed and on site.

It is your responsibility to determine if a resource consent is required and, if so, that the resource consent has been applied for and approved prior to starting any work.

All consented documents and plans must be printed in colour (if on original), to scale and available on site at all times. If not, the inspector may be unable to undertake the inspection until these are available and you will require a re-inspection which will incur an additional cost.

To help inspectors identify your particular site, please ensure adequate signage is in place, especially in remote or rural locations.

WHEN BOOKING AN INSPECTIONPlease phone: 03 546 0334 - leave a message giving 2-3 working days’ notice where possible. We will generally ring back and confirm your booking within 4 hours.

Please leave the following information:

• Your Name

• Telephone contact number

• Building consent number

• Address of property to be inspected

• Type of inspection required

Refer to the site inspection schedule for the inspection code number and the order in which the inspections are listed in the consent documents.

NB Colour ‘As Built’ Truss plans must be provided to Council (preferably via email to [email protected]) prior to booking a structural inspection.

• Your LBP number

• Day you would like the inspection & specify morning or afternoon

• Contact name and phone number of the person on site, and lock box (or gate) code

Any amendments relevant to the inspection being booked must be approved by Council before the inspection can be accepted (see page 23-25 for guidance on amendments).

In some circumstances you may need to provide scaffolding, a ladder or scissor lift in order for difficult building elements to be inspected e.g. a chimney back flashings or roof gutter.

Rural properties can be difficult to locate – signs at the gate (or directions in the message) are helpful.

A complete & legible copy of all the current issued building consent documents must be printed to scale, in colour (if on original) and be on-site at all times.

If these are not available it will affect our ability to carry out the inspection, result in a failed inspection and incur additional charges that must be paid prior to your Code Compliance Certificate being issued.


PLEASE NOTE: For residential building consents, the Inspection Code may be suffixed with the letter R – signifying Restricted Building Works.

DEALING WITH AMENDMENTSGetting amendments approved quickly is essential otherwise your job might grind to a halt.

Helpful HintsArrange written approval from the owner or agent when changes from the building consent are being proposed. Often a seemingly simple building material change can cause issues if the designer/agent/owner is unaware of it.

To avoid delays, it is vital that the following documentation is provided:

• Amendment application signed by owner/agent.

• Specific installation/construction details.

• Amended plans using the most recently consented drawings.

• Highlight or ‘cloud’ the specific changes for ease of processing.

• Ensure original design memorandum is still applicable. This may require the applicant to provide a revised memorandum specific to the amendment. If in doubt, please consult the original designer.

• Applicants should be aware that, under the Building Act, amendments may take 20 working days to process. The size of the amendment in no way relates to the amount of time it may take to be processed.


KEY TERMSFor the purposes of this guide, a ‘variation’ refers to any proposed or agreed change to consented building work.

An ‘amendment’ means a change made to the original building consent, be it a simple alteration like a handwritten note on the consented plans by the consent applicant, builder, designer (informal), or through a formal amendment as set out in the Building Act 2004 and Building (Forms) Regulations 2004.

All amendments must be approved and recorded by the building consent authority.

Application forms can be downloaded from Nelson City Council’s website as follows:

• Building Consent / Amendment application form: http://nelson.govt.nz/building-and-property/building-consents-2/building-consent-applications/apply-for-building-consent/

Variation identified

Minor variation Major variation

Informal amendment possible.

Note made on consent file. May include amended drawing or updated site record memorandum.

Formal amendment required.

Requires owner/applicant to complete a building

consent application form and lodge with BCA.

Do not carry out building work that is a variation from the approved consent until the proposed variation has been discussed and approved (whether formally or informally) by the building consent authority.


HOW DO YOU ASSESS WHAT IS A MINOR OR MAJOR VARIATION?As noted, it is very common for variations to consented building work to take place during a construction project. The question to consider is whether the change is considered minor or major in nature.

The following explanations of ‘minor’ and ‘major’ variations are to assist us to more effectively determine what is considered to be ‘minor’ or ‘major’ variations, and then consistently handle each of these.

Minor variationsA variation that is minor is a change that does not usually affect compliance with the Building Code – for example, the type of taps used or positioning of kitchen joinery or non-structural walls or door.

Most often the minor variation does not affect the level of Building Code compliance; it simply achieves the same outcome in a different way.

A building consent authority must still be notified about any proposed variation so it can confirm the change is minor; advise how they will deal with it and record the minor variation in writing. Minor variations shouldn’t usually require a Form 2 and, if approved, do not require the issue of an amended building consent. However, all minor variations that are approved must be recorded in writing (e.g. a handwritten note on the consented plans and inspection record note).

Examples of variations that are minor to building consents include:

• substituting one internal lining for a similar internal lining

• substituting the type of timber treatment

• minor wall bracing changes

• a change to a component (e.g. fixing bracket)

• a construction change (e.g. the framing method around a window when the window is changed to a door)

• changing a room’s layout (e.g. the position of fixtures in a bathroom or kitchen)

• changing one brand of insulation for another

• building work described in schedule 1 of the Building Act 2004.


The plans and specification specify wire dog purlin fixings, but the builder wants to use a screw instead. In this case the same level of compliance would be achieved.

This is a minor variation. The building inspector simply records on an inspection report or memorandum that the purlins are screw fixed from the top rather than wire dogged. This note then goes on the consent file.

A bathroom is approved to be laid out in a particular way. During the project it becomes necessary to move the vanity along the wall to accommodate the door opening and rotate the toilet 90 degrees. In this case, the changes are within the scope of the approved building consent.

This is a minor variation that the building inspector could receive via another drawing showing the new location.

This drawing would be added to the consent file as as-built documentation prior to the issue of a code compliance certificate.

The following scenarios outline proposed variations that are minor and require an informal amendment to consented building work:


The building inspector visits the site for the foundation inspection prior to pouring the perimeter foundation. On arrival the inspector is told the foundation is to be changed from slab on ground to a pile foundation.

This would be a major variation because it is a significant departure from the approved building consent and the change could significantly affect the structural integrity of the building. The inspector requests that work on site stops until the applicant has applied for a formal amendment to the issued building consent (providing new plans, detailing the construction change) and the amendment has been granted.

The plumbing inspector visits a site to undertake a pre-line plumbing inspection for a new two-storey dwelling. At the inspection, the inspector identifies that although the specification details a G13/AS1 graded stack compliant system, the plumber is about to install an AS/NZS 3500 elevated drainage system.

Because this is a completely different design principle at play, with different plumbing from the approved building consent, the inspector considers this a major variation and requires that a formal amendment to the consent be made. The plumbing work ceases until the new design has been documented, submitted to the BCA and the amendment is granted.

Major variationsGenerally, where the work is outside the scope of the original consent (e.g. additional footprint or increases in floor area, construction method, or significant changes to the layout), this would be considered a major variation. A formal amendment would be required for the new work to be undertaken.

Variations that are major often result when the variation impacts on a number of Building Code clauses.

The following examples demonstrate where compliance with the Building Code will be significantly affected (a major variation), therefore providing a trigger that a formal amendment is required. If approved, any amended application becomes part of the approved building consent documents file for that building project.

Examples of major variations:

• A deck or carport shown on the building consent drawings is no longer to be built.

• The applicant wants an en-suite bathroom to be installed instead of a walk-in wardrobe shown on the building consent drawings.

• A change to the assembly (e.g. acrylic shower unit to a tiled shower unit)

• Timber joists complying with NZS 3604 are shown on the building consent drawings, but the applicant is advised by the builder to change to a manufactured proprietary joist system.

• The applicant wants to change part, or all, of the proposed cladding system from that approved in the original consent.

• A new house is approved with a perimeter foundation wall and ordinary internal piles, but it is decided instead to construct a complete timber pile foundation.

The following scenarios outline situations of proposed variations that are major and require a formal amendment to consented building work:
