Consent & compliance
When a renovation needs an LBP
Restricted building work is the main trigger for needing a Licensed Building Practitioner. It covers residential work on the primary structure, weathertightness and the design of certain fire safety systems, where a building consent is required. This work must be designed, carried out or supervised by an LBP holding the right licence class. Ask your designer which parts of your project fall into this category.
Check that the licence matches the task. Licence classes include design, carpentry, site, roofing, foundations, external plastering and bricklaying and blocklaying. A roofing licence does not cover structural carpentry, for example. Search the public LBP register by name or licence number and confirm the licence is current. Do this before signing a contract, not after work has started.
Collect the paperwork that LBPs must provide. Designers provide a certificate of work with the consent documents, and builders provide a record of work when they finish their restricted building work. The owner should receive copies, and the council needs them for the final sign-off. Put these documents on your handover checklist so they are not forgotten when trades leave site.

Cost and time
How to build a more reliable budget and programme
A fixed price or completion date needs a measured scope and a site visit. This content is general information only. Confirm requirements with Auckland Council and appropriately qualified professionals before work starts.

Risk control
Common mistakes to avoid
- Using a general trade title does not prove the required licence class for specific work.
- assuming consent-exempt means code-exempt
- relying on general online advice instead of checking the actual scope

Common questions
Frequently asked questions
How do I check if my builder is a Licensed Building Practitioner?
Search the public LBP register on the Licensed Building Practitioners website using the builder's name or licence number. The register shows the licence class and whether it is current. Ask for their licence number before you sign anything, and check that the class suits the work they will carry out.
Can I do restricted building work myself as a homeowner?
There is an owner-builder exemption, but it has strict conditions and must be applied for through the consent process. Owner-builders carry the responsibility for the quality and compliance of the work. Check the current criteria on the Building Performance website and think carefully about the risks before choosing this pathway.
What is a record of work from an LBP?
A record of work is a document an LBP must provide when they finish restricted building work, stating what they did or supervised. It goes to the owner and the council. It helps show who was responsible for each part of the work, which matters for compliance sign-off and any future questions about the building.
