Buying a fixer-upper can be an excellent way to enter the property market or unlock long-term value, but homeowners often underestimate the approvals required before renovation work begins.
According to Meridian Realty principal Antonie Goosen, not every improvement requires municipal permission, but structural changes almost always do. "Many buyers believe that once the property is theirs they can immediately start renovating. In reality, certain alterations require municipal approval before any work begins," he says.
He explains that cosmetic improvements such as painting, replacing flooring, installing new kitchens or renovating bathrooms can usually proceed without formal approval. "Purely cosmetic work generally doesn't require building plans," says Goosen. "However, the situation changes when you're altering the structure of the building."
Removing walls, extending rooms, adding garages, building entertainment areas, installing new roofs or making other structural modifications will often require approved building plans from the local municipality.
"Starting structural work without approval can become very expensive," he warns. "Municipalities can require work to stop, impose penalties or insist that non-compliant alterations be corrected before the property can be sold."
He says buyers should also remember that additional approvals may be needed if the property is located within a homeowners' association or sectional title scheme. "Estates and sectional title developments often have architectural guidelines that owners must follow in addition to municipal regulations," he explains. He recommends that buyers investigate renovation requirements before making an offer if major improvements form part of their plans.
"Understanding the approval process upfront helps buyers budget accurately and avoid unnecessary delays once transfer has taken place," he says. Proper planning, he adds, often saves considerably more time and money than trying to correct unauthorised work later.

According to Skoko Sebola, Principal at Leapfrog Midrand, preparation is important. "We often see homeowners dive into projects based on emotion, but the legal framework is what ensures your investment is actually protected," he explains. "Being ready for a renovation isn’t just about having the budget in place. It means being legally compliant."
Sebola emphasises the transactional risks. "We regularly see sales fall through or prices drop significantly when unapproved building work is discovered during the transfer process. It's much easier to get it right from the start than to fix it later."
Minor works vs major renovations
The regulatory requirements depend entirely on the scope of your project. Minor works include internal changes that don't affect the building's structural integrity or its external footprint. These typically don't require municipal approval. Replacing kitchen cupboards, updating bathroom fixtures, or repainting falls into this category.
Major renovations trigger regulatory requirements. The moment you alter load-bearing walls, change the building's footprint, modify the roof structure, or convert a room's intended use, you've entered regulated territory. Converting a garage into a flatlet, for instance, constitutes a major renovation requiring full approval.
The distinction matters because unapproved major work creates serious consequences. "Trust your agent's market analysis; unapproved structures often hold no legal value in a transaction," Sebola warns. "Buyers view properties with unapproved structures as high-risk, frequently demanding substantial price reductions or walking away entirely."

Navigating municipal plan approval
The National Building Regulations and Building Standards Act requires municipal approval for major construction. The process begins with engaging a registered architect or senior draughtsperson from the South African Council for the Architectural Profession (SACAP).
Every property has building lines. These are invisible boundaries determining how close you can build to property boundaries and the street. If your project extends beyond these lines, you must apply for a departure or relaxation, which is a formal municipal application that allows you to build closer to your property boundary than zoning rules normally permit. This adds significant time and typically requires neighbour consent.
Sebola advises patience during this stage. "Homeowners often want to rush the municipal approval process, but cutting corners here creates legal complications that can take years to resolve. The waiting period is frustrating, but it's protecting your property rights."
