Building Plans

Frequently asked questions
What kinds of building activities require building plans to be submitted for approval?
A building plan application must be submitted for any structure, whether this is of a temporary or permanent nature and irrespective of the materials used to build it. This includes alterations or extensions to existing structures. The only exceptions are buildings smaller than 5m², a pergola (without a permanent roof), wire fence or open-side fabric-covered shelter for a car, boat or caravan.
Who may prepare building plans?
In terms of the Architectural Profession Act (Act 44 of 2000), architects, technologists and draughtspersons who are registered with the South African Council for the Architectural Profession may prepare building plans.
How long does a building plan take to be approved?
In terms of the National Building Regulations and Building Standard Act, the City has 30 days to approve or refuse a building plan application for buildings smaller than 500m² and 60 days for buildings larger than 500m².
Do I need to inform my neighbour of my proposed building works?
No (although it is considered good practice), unless the application also includes departure from the zoning scheme regulations (such as building line relaxation, increased bulk/coverage/height etc.) or similar proposals, in which case formal consultation is required.
How do I complain about illegal building work?
Deliver your complaint in writing to your nearest district planning office, by hand, fax or post. No anonymous complaints are accepted, as you may be required to give evidence. The written complaint must include your name and address, the name and address of the alleged offender and a detailed description of the alleged contravention.
What are the consequences of building without approved plans?
A building inspector may serve an order to stop any illegal building work immediately, which if ignored may lead to a fine or even further prosecution and a court order to demolish the structures concerned.
