Class 7 Buildings

Overview

This article outlines the classification of Class 7 buildings under the National Construction Code (NCC), including their sub-categories and special requirements such as solar panel allowances.

Why This Is Important

Helps identify when a structure is classified as Class 7a or 7b.
Ensures compliance with NCC 2022, including solar panel allowances.
Clarifies the difference between wholesale and retail structures.

Understanding Class 7 Classifications

1. Subclassifications

Class 7 buildings include two sub classifications:

Class 7a buildings are carparks.
Class 7b buildings are typically:
- Warehouses
- Storage buildings
- Buildings for the display of goods (or produce) for wholesale purposes.

2. Solar Panel Requirement

Under NCC 2022, Class 7 buildings now require allowance for solar panels.

3. Wholesale Definition

Did you know?
The term wholesale refers to the “sale to people in the trades or in the business of ‘on-selling’ goods and services to another party (including the public)”.

Tips, Best Practices & Troubleshooting

Confirm if the building’s purpose is car parking (Class 7a) or storage/wholesale (Class 7b).
Check with your engineer or supplier if solar panels need to be factored into the design.
Avoid confusing wholesale display buildings (Class 7b) with customer-facing retail environments (Class 6).
