In both planning and building contexts, a “change of use” means a building or site is proposed to be used for a different purpose than it was previously approved for.
In planning terms, this relates to whether the new activity is permitted under the District Plan. For example, turning a retail shop into a café, converting an office into a daycare, or using a warehouse as a gym may trigger planning considerations such as parking demand, noise, traffic, or operating hours. If the new use is not permitted by the District Plan, a Resource Consent may be required.
Under the Building Act 2004, a “change of use” has a specific legal meaning and applies when a building changes between defined use categories (for example, from a household unit to an early childhood centre). When a change of use occurs under the Building Act, Council must be satisfied that the building will comply, as nearly as is reasonably practicable, with the Building Code provisions relating to:
- means of escape from fire
- access and facilities for persons with disabilities (where required)
- protection of other property, sanitary facilities, and structural performance.
As a result, a change of use may require building upgrades. For example, a building that was previously a shop may need additional fire safety measures, accessibility upgrades, or upgraded services to operate as a food business. Converting a house into a preschool or gym may require changes such as accessible toilets, additional exits, fire separation, or seismic improvements.
Because a change of use can involve both planning approvals and building compliance obligations, it is important to check with Council before committing to a new use. In some cases, a Building Consent may be required for associated building work or upgrades, even where the physical changes are internal.
Council staff can advise whether your proposal constitutes a change of use under the Building Act, whether Resource Consent is required under the District Plan, and what approvals or assessments are needed to ensure the building can be lawfully and safely used for its new purpose.
