Choosing the right people for your type of building work
Last updated: 16 March 2018
Make sure your building professionals are right for your project and can confidently meet Building Code requirements.
Before you start your building project
The rules about building change for different types of buildings, what they’re used for and how they’re built. You will need to hire people with suitable skills and experience for your job. You must use licensed people for some residential building and design work.
Most plumbing, electrical and gasfitting work must be undertaken by licensed or certified people.
Think about whether your project:
- is simple, average or complex
- needs a building consent
- needs a licensed building practitioner (LBP), ie involves restricted building work
- is a renovation or new build
- has more than one ‘use’ (such as a shop, with an apartment attached).
A complex project could mean one with innovative design, techniques or products. It can also refer to a difficult site or renovation. Renovations often pose more challenges than new builds.
It makes sense to use practitioners with suitable experience and skills. They key things are to:
- ask for references
- get more than one quote
- get a contract (or at least an agreement in writing).
Use licensed people for restricted building work has more information on why you need an LBP.
Work on a home
A safe, healthy and durable home is important – to your family, finances and future. Some design work and building work to a house, townhouse or small apartment building is so important it must be done or supervised by an LBP.
Restricted building work sets out which projects you must hire an LBP for. Generally, this will be work to the structure or weathertightness of a home. It also covers fire safety design in smaller apartment buildings.
LBPs are designers, builders, roofers, external plasterers, brick and blocklayers, foundation and site workers. LBPs are licensed and their skills and knowledge are regularly assessed for currency.
Work on other buildings
Commercial and other buildings are likely to need the services of design professionals, or engineers where a building consent is required. The plans and specifications in the building consent need to demonstrate how the proposed work meets the requirements of the Building Code.
You can choose to use builders or tradespeople who are LBPs whether or not one is required.
If you are planning work to an existing building with a specified system (certain safety and essential systems), the compliance schedule may need to be amended.
Amendments to compliance schedules has more information.
