If a garage, carport, flatlet or extension does not match the approved plans, first establish what was approved and how the property is being used. Missing building approval and a land-use contravention are different problems, and both can apply to the same structure.
1. Obtain the records before deciding on the remedy
Request copies of approved building plans and available land-use decisions from the municipality. Find the title deed, survey diagram and any estate or homeowners’ association approvals. Ask an architectural professional to compare the records with the building on site. An old drawing, rates valuation or description in a sale agreement is not by itself proof of approval.
2. Separate the issues
| Possible problem | What needs investigating |
|---|---|
| Work is absent from the approved plans | The building-plan submission, technical compliance and any required inspections or remedial work. |
| A structure crosses a building line or exceeds another parameter | Whether an exemption, permission, departure or another planning process is applicable. |
| A garage is now a separate flat or business | Whether the use is lawful, as well as whether the building is suitable and approved for it. |
| The title deed or estate rules restrict the work | The separate legal or private approval requirements, with the appropriate professional advice. |
3. Agree a coordinated regularisation route
A planner identifies the land-use applications and planning constraints. An architect or registered draughtsperson prepares the building documentation, with engineering or other input where necessary. The municipality assesses the required applications. An as-built plan records what exists; it does not make the structure lawful simply because it has been drawn.
Where the municipality uses administrative penalties or another enforcement process, establish the required sequence and respond to notices within the stated period. Penalties and procedures vary. Paying a penalty or lodging an application does not guarantee that the building or use can remain. Design changes, a reduced proposal or removal may be necessary if approval cannot be obtained.
What if I bought it this way?
The fact that a previous owner constructed or used the building does not establish approval. Ask your conveyancer or attorney about the contract, disclosures and any potential claim. At the same time, investigate the planning and building position so you understand the practical options. A planner cannot determine your contractual remedies, and a contractual dispute does not resolve municipal compliance.
A practical example
An owner discovers that a garage has been enclosed and fitted with a kitchen. The investigation should check the original garage approval, the rules for a separate dwelling, parking lost through conversion, building lines and building compliance. The solution may require both planning and building work; submitting the existing floor plan alone may not address the change of use.
Send the address and erf number, approved plans if available, photographs, a rough description of the changes and all municipal notices. Ask for a scope separating records investigation, planning applications, building submissions and any work needed after a decision.
