We are here to help make sure you meet any legal requirements and get through the building consent process.
If you are not sure whether you need building consent, contact us on 03 941 8999 to discuss this with a duty building consent officer. You may also need to talk to a planner to see if you need resource consent.
You may also want to check out Ministry of Business, Innovation and Employment’s (MBIE)(external link) for advice and guidelines on building regulation.
A building consent is a formal approval to undertake building work in accordance with approved plans and specifications. A building consent establishes that the Council has reasonable grounds to believe that your proposed building work complies with the building code(external link) and therefore meets the safety standards set out in the Building Act 2004(external link).
The Building Act (administered by MBIE(external link) sets out the rules for the construction, alteration, demolition and maintenance of new and existing buildings in New Zealand. These rules ensure that:
The building code sets the mandatory standards for building work. All building work in New Zealand must comply with the building code. The building code states the performances a building and its components must meet.
It's an offence to build without a building consent if one is needed. It could result in fines and possibly the removal of the building work. It may also make it difficult for you to sell the building or get insurance.
Working through the building consent process provides building owners with documented assurance that they have taken all the right steps.
In general, you must have building consent before you start any building work.
Some types of building work that is considered low risk may not need building consent under the Building Act.
Visit the MBIE’s website for information on building work that does not require building consent(external link) or use MBIE’s Buildit tool(external link) to answer a few questions about your upcoming project to see if it needs building consent, or could qualify as exempt building work.

Sections 71-74 of the Building Act 2004 are concerned with building on land which is subject to natural hazards, such as flooding, slippage and erosion. There are risks in building on land subject to natural hazard for both the owner and Council. Under the Building Act, natural hazard means any of the following:
When there is the construction of a building, or major alterations to a building, on land subject to a natural hazard, section 72 allows a building consent to be granted in certain situations but requires a notice to be placed on the property title. This notice warns future property owners of the natural hazard and takes away Council liability if there is damage as a result of the natural hazard.
While in almost all cases the granting of the building consent will have decided that the building work will comply with the building code, the natural hazard notice is still required to recognise that the land is subject to a natural hazard.
Natural hazard notices may affect the value of your property and your insurance cover, including disaster insurance provided by the Earthquake Commission (EQC). If you think natural hazards may apply to your project the Council recommends you seek professional or legal advice so you can make fully informed decisions.
We also recommend that you book a pre-application meeting(external link) to help you understand how the natural hazards provisions may affect your project.
Where Council considers that the land is subject to a natural hazard we are required to grant the building consent under section 72. Before we do this, we will ask the owner to acknowledge in writing that they are aware of the implications of the notice and have taken the opportunity to seek advice.
Building work affecting the primary structure or weather-tightness of a residential building is restricted building work under the Building Act 2004.
The rules mean you must employ a licensed building practitioner to design, carry out or supervise this kind of building work.
The rules make sure that critical design and building work is carried out or supervised by competent practitioners. It also makes sure there is accountability if the restricted building work does not meet the required standards.
Visit MBIE’s website for information on restricted building work(external link).
While most building work will need building consent, you can do some building work without building consent. You do not need a building consent to carry out building work that is either:
The LBP scheme was launched in November 2007 following an amendment to the Building Act 2004. Its purpose is to encourage competent building practitioners to build homes right the first time. The scheme also gives consumers the necessary information to make informed decisions about the competence of building practitioners they may engage
The LBP scheme is structured into seven licensing classes(external link), each based on a specific role or occupation that is crucial to a building's performance.
LBPs are designers, carpenters, brick and block-layers, roofers, external plasterers, site and foundations specialists who have been assessed as competent to carry out work affecting the primary structure or weather-tightness of a residential building. Chartered professional engineers, registered architects, plumbers and gasfitters are treated as LBPs and can carry out some restricted building work.
If your building project needs building consent from the Council, it may be restricted building work. Visit MBIE’s website for more information on choosing the right people for your type of building work (external link)for restricted building work.
Your building consent application must include details of the LBPs involved in your project. Your designer must be an LBP and must include a memorandum from a licensed building practitioner: Certificate of design work(external link), stating the design work complies with the building code.
Each licensed building practitioner who is subsequently involved in the project (e.g. foundation specialist, carpenter, bricklayer, external plasterer and roofer) must provide their LBP number and a record of work(external link) to the owner and Council. These records of work must be submitted with the application for a code compliance certificate.
To find who is a licensed building practitioner, go to MBIE’s webpage on licensed building practitioners(external link).
To avoid delays in processing your building consent, be sure your application includes a certificate of design work from all LBPs involved with designing the restricted building work. The details of other LBPs can be added as they are engaged to do the building work if you do not know them at the time of application.
As an owner-builder, you can carry out restricted building work on your own home. You are responsible for ensuring that restricted building work carried out under the owner-builder exemption complies with the building consent and the relevant plans and specifications.
You are an owner-builder if you:
Visit MBIE’s website for information on obligations and responsibilities of owner-buildings and their building project (external link)and the required forms to use the owner-builder exemption.
A project information memorandum (PIM) is a report issued by the Council under Section 31 of the Building Act 2004 at the request of an applicant that contains information known to the Council about your property and may be relevant to your building project.
View project information memorandum (PIM) for further information, what is contained in a PIM, how to apply or withdraw, and fees.

In-person: deliver your application to the Council office at 53 Hereford Street, Christchurch.
All building and land-use projects must comply with the rules in the Christchurch District Plan(external link).
If your project does not comply with the district plan you’ll need to get a resource consent(external link) approved under the Resource Management Act 1991 before some or all of the building work can commence. The extent of work that can be carried out will be detailed in a certificate attached to the building consent (section 37 of the Building Act).
A producer statement is a document where the author declares a professional opinion based on sound judgment and specialist expertise that the design or the building work complies with the building code.
A producer statement, along with appropriate supporting documentation, may provide a building consent authority with good evidence so that they are satisfied on reasonable grounds to grant a building consent or issue a code compliance certificate.
Producer statements are typically used for specialist work, such as the design and review of building work that requires specific engineering design.
There is also a type of producer statement for construction. These statements are typically provided by contractors who have installed a product or system.
There are four types of producer statements:
In considering what weight to give to a producer statement, Council will assess the qualifications of the author to ensure that person has the appropriate experience and competence in their area of practice to design or review the building work.
For a producer statement to be appropriate, the author should be currently registered with a professional body, the scope of the statement must be within the practice area of the author and all the fields on the Council’s producer statement template completed.
If the author is a member of Engineering New Zealand, NZIA, or ACENZ, the statements can be submitted on the relevant professional body's standard template. If the producer statement does not meet these requirements the Council may place little reliance on it and require further evidence of compliance.
Alterations to an existing building (section 112)
If your application is for an alteration to an existing building, you need to consider section 112 of the Building Act 2004 and provide supporting information on:
Change of use of a building (section 115)
If a building owner intends to change the use of a building (or part of a building) they must first give notice in writing to the Council of that intention and have received confirmation from the Council that the change is approved.
Buildings with specified intended lives (section 116)
If your building is intended to have a life of less than 50 years, you must state the intended life of the building on your application form.
A specified intended life applies to the whole building, not a building element (such as a solid fuel burner) or a building system (such as a cladding system).
When we assess your application, we will decide if it is applicable to grant the building consent with a specified intended life subject to the conditions required by section 113, Building Act 2004(external link).
The standard condition will state that the building must be altered, removed or demolished on or before the end of the specified intended life. Council will also add to the condition that, should an application to alter the building to extend its life be made under section 116, the durability of the building must be shown to be of a standard appropriate to the extension of life requested.
If you want to extend the life of your building that has a specified intended life, section 114(external link) requires that you must give written notice to Council. For Council to be able to give written consent it will require a building consent application to assess the building has been altered as per section 116(external link).
Subdivision of an existing building (section 116A)
The Council cannot issue a subdivision affecting a building or part of a building unless it has considered section 116A of the Building Act 2004. This will be assessed with your application for unit title subdivision(external link).
Commercial applications with specified systems
If your application is for a commercial project, you need to include a list of all specified systems for a new building or the specified systems being altered, added or removed as a result of the building work for a building with an existing compliance schedule.
The application needs to also include the proposed inspection, maintenance and reporting procedures for those specified systems. More information can be found on the specified systems guidance - Form B-068 [DOCX, 94 KB].
Fees vary for building consent applications depending on the type of project.
Refer to the building consents fee schedule(external link), which also outlines further detail on how to pay including levies to be paid.
Also, refer to our guide to building consent fees and charges for estimated building consent fees based on a project value.
If you wish to make changes to your building consent, you can apply for a minor variation or an amendment. A minor variation or amendment must be granted before the building work is carried out.
See minor variations or amendments to a building consent (external link)to check if your change is a minor variation or an amendment, including information on how to apply and associated fees.
Building consents are valid for 12 months from the date of issue.
Building work must have commenced within 12 months or the building consent will automatically lapse unless an extension of time to start work has been requested.
If the building consent has lapsed you will need to apply for a new building consent if you want to proceed with the building work.
To apply for an extension, please either:
Your letter needs to include the following information:
A fee applies for the extension, please refer to the Notice to fix section under building inspection fees(external link).
Once the building consent is issued the building work may begin, but in some circumstances, resource consent approval(external link) may still be required.
In these circumstances, a certificate attached to your building consent (section 37 of the Building Act) will restrict the starting of building work until resource consent is obtained.
If you are a commercial building owner where the public is to be admitted, and you want to start using premises before a code compliance certificate is issued, you must apply for a certificate for public use. This certificate enables members of the public to use the premises until a code compliance certificate is issued.
Certificates for public use can be used only where a building consent has been granted for the building work, but a code compliance certificate has not been issued yet.
View certificate for public use(external link) for further information including how to apply, what information you need to supply, statutory timeframes, fees etc.
