Understanding Sectional Title: The Basics

Before 1973, buying a flat in South Africa was legally tricky — you couldn't register title to just a portion of a building. The law has come a long way since then.

For most of South Africa's legal history, the Deeds Registry could only deal with land — and land was treated as a flat, two-dimensional surface. A diagram showed your erf, its boundaries, its beacons. It said nothing about what stood on top of it. This meant there was no clean way to give someone legal ownership of, say, apartment 7B on the third floor of a building sitting on a single piece of land.

That changed in 1973, when South Africa's first Sectional Titles Act came into force, introducing a three-dimensional concept of property ownership. For the first time, a building could be officially divided into individually owned "sections" — each with its own title deed, each capable of being bought, sold, bonded, and inherited independently. The current governing legislation, the Sectional Titles Act 95 of 1986, replaced that original Act and remains the foundation of sectional title law today.

The term "sectional title" covers a surprisingly wide range of property types. A high-rise apartment block in Cape Town's CBD qualifies. So does a cluster of six semi-detached townhouses in Somerset West, a retirement village in the Winelands, or even a row of detached chalets where each chalet forms its own numbered section. The common thread is that multiple people share both individual ownership of their sections and collective ownership of the land and shared spaces around them.

When you buy a freestanding house on its own stand, you get full title. When you buy into a complex or apartment block, you almost always get sectional title. The legal implications are very different.

When someone owns a property in "full title" (also called freehold), they own both the land itself — as surveyed and registered in the Deeds Registry — and everything permanently attached to it. The boundaries go down to the centre of the earth (in theory) and up into the air above. Your title deed describes your erf number, its dimensions, and its registered owner. You're in charge. No body corporate tells you when to paint your fence.

Sectional title is a fundamentally different animal. You don't own the land beneath your unit — that land belongs collectively to all the owners in the scheme. What you own is a defined, three-dimensional space within or alongside a building, as shown on an officially approved plan. Your rights, obligations, levy contributions, and voting power in the scheme are all linked to the size of that space relative to the whole.

Without the sectional plan, there is no scheme. It is the single most important document in any sectional title development — the architectural and legal blueprint that brings the whole arrangement into legal existence.

Think of the sectional plan as the master map of the entire scheme. It is prepared by a qualified land surveyor or architect and, once completed in draft form, must be submitted to and approved by the Surveyor-General. Once the Surveyor-General's stamp of approval is on it, the draft becomes an official sectional plan — and only then can the Registrar of Deeds register it and formally open a sectional title register for the scheme.

A properly completed sectional plan consists of at least four separate sheets, each serving a distinct purpose:

A section on the plan may consist of non-adjacent parts of a building — imagine a section whose lounge is on the ground floor and whose main bedroom is on the second floor of the same building. And in some schemes, an entire detached building (like a standalone chalet or cottage within a development) may form a single numbered section on its own.

The short answer: you own a "unit." And a unit is more than just the physical space you live in — it's a bundle of rights with two inseparable parts.

When people talk about owning a flat or a townhouse in a sectional title scheme, they often think of it simply as owning the physical space — the walls, the floor, the ceiling of their apartment. But the legal answer is richer than that.

In sectional title law, you own a unit. The unit has two indivisible components:

This is not just a technicality. It has real practical consequences. Your ownership of the common property is not a vague, informal arrangement — it is a formally registered real right. It appears in the Deeds Registry. It is recognised by the courts. And it comes with both benefits (the right to use and enjoy the common areas) and obligations (the duty to contribute to their upkeep through monthly levies).

The participation quota is the mathematical formula at the heart of sectional title. It determines your share of the common property, your voting power, and your monthly levies — all in one number.

A "section" is simply the specific part of the building shown on the floor plan with your assigned number. A section can be almost any shape or size — a studio apartment, a three-bedroom penthouse, a garage, a storeroom, or even a detached building in a development. The key is that it is shown on the plan, it has a number, and its floor area can be measured.

A "unit" is the section plus its undivided share in the common property. Think of it this way: you cannot legally own just the section without also owning a slice of the common property. They come as a package.

How the Participation Quota Is Calculated

For a scheme used exclusively for residential purposes, the participation quota of your section is calculated as follows:

Total scheme floor area: 400m². Your 80m² section ÷ 400m² = 20.0000% participation quota.

For non-residential schemes (office parks, retail centres), the developer has the flexibility to determine participation quotas based on factors other than floor area — though no section may be allocated a quota of zero or a negative amount.

The quota also determines your vote weight in certain body corporate resolutions where votes are counted by value rather than by the number of owners. And when a building is catastrophically damaged or deemed destroyed, the participation quota determines each owner's share of the land that reverts.

The swimming pool. The entrance lobby. The garden. The roof. In a sectional title scheme, anything that isn't part of a numbered section is common property — and it belongs to everyone.

Common property is defined by what it is not: anything in the scheme that is not included within the boundaries of a numbered section on the sectional plan. This creates a neat rule of thumb — if it's shown as a section on the plan, it belongs to the owner of that section; if it isn't, it belongs to all owners collectively.

Common property has three distinct elements:

Common Examples of Common Property

Your covered parking bay, your private garden, your storeroom — these feel like yours. And in a well-run scheme, they are. But the legal mechanism behind this is more nuanced than most people realise.

Here is the counterintuitive truth: your parking bay, your back garden, your storage cage in the basement — these are all technically common property. They sit on the scheme's land and form part of the building's shared areas. But the law allows the developer (and in certain circumstances the body corporate) to reserve portions of the common property for the exclusive use of the owner of a specific section.

These designated areas are called exclusive use areas. They must be shown on the sectional plan and their permitted purpose must be declared — "parking area," "garden area," "store room," and so on. The exclusive nature of the right is what distinguishes them from the common property available to all owners.

Two Very Different Types of Exclusive Use Rights

Not all exclusive use arrangements are equal. There is a critical legal difference between registered exclusive use areas (which are real rights) and those created merely by the scheme's rules (which are personal rights only):

Buying into a complex with 20 units doesn't mean you'll always live in a complex of 20 units. Under certain circumstances, the developer — or the body corporate — can extend the scheme and add more. Here's what you need to know.

When a developer first opens a sectional title register and begins selling units, they often don't build everything at once. A developer may sell Phase 1 of a development first, and reserve the right to add Phase 2 (more sections, more buildings) at a later stage. The legal mechanism for this is called a real right of extension, provided for under section 25 of the Sectional Titles Act.

From a buyer's perspective, a registered right of extension means that the complex you are buying into may look quite different in five or ten years' time. More buildings, more units, and more owners could be added — which affects everything from traffic in the estate to the use of communal facilities to the calculation of levies. This is why the law requires disclosure, and why your conveyancer will check the scheme's register carefully before you sign.
