From the outset it must be clearly stated that not all businesses being operated from a residential property is illegal and unlawful. There are a number of aspects that must be considered to determine whether or not the business may be operated from a residential property or not.
A first aspect is the title deed of the property which needs to be assessed to determine whether there are any restrictive conditions registered against the property which may prohibit the property being used for business purposes. A further aspect to be considered is the zoning of the property and whether such property is zoned for residential use or also for business use – and then further also what type of business use. You can determine the title conditions of a property at the Deeds Office, or with the assistance of an attorney and the zoning of a property through an enquiry at your local municipality.
Should there be a restrictive condition or the property be zoned for residential purposes making it unlawful for a business to operate from the property, you will have to consult your attorney to consider obtaining an interdict prohibiting the use of the property for business purposes. In a situation where a final interdict is sought you will have to prove the following: 1) you as owner have a clear right; 2) that the conduct of operating the business from the property is causing prejudice or an infringement of your rights (injury) and; 3) the absence of an alternative remedy.
Our courts have found that if a property is used in contravention of its zoning rights, the use is unlawful and therein lays the injury/prejudice. When considering an alternative remedy, it must be adequate in the circumstances and must reasonably afford similar protection as an interdict. As the infringement of using the property in breach of the zoning restrictions is ongoing and an offence in law, an interdict has been found to in certain circumstances be the only effective remedy available. That said, each and every situation must be assessed on the merits thereof.
A last point that should be mentioned is where consent from the local authority is obtained to use the property for another purpose than what it is zoned for. Even if such consent has been obtained but the restrictive condition remains in place on the title deed, the use of the property will still be unlawful if it is not in line with the restrictive condition on the title deed, at least until such condition has been amended or lifted.
So in your case, it does appear that if the businesses are operating from residential properties, there could be grounds to bring an interdict to stop such businesses should they be in conflict with either their title conditions and/or zoning. My advice is to contact your attorney and determine whether there are grounds to bring an application against these businesses. You may even consider involving some of your neighbours who are also concerned about the businesses opening up in you neighbourhood.
If you are faced with a situation where you live in a residential area and businesses are opening up around you, consult an attorney to assist with the appropriate action.
