The Site That Tells You All About The Building Regulations In South Africa
SANS10400.org.za Introduction
The Building Regulations are a set of guidelines and standards that govern the construction of buildings, ensuring the safety and well-being of those who use them. In South Africa, the primary Building Regulations are contained within the SANS 10400 series, which are developed and maintained by the South African Bureau of Standards (SABS). These building standards cover a wide range of topics, from fire safety and electrical installations, to energy efficiency and accessibility for people with disabilities.
SANS 10400 provides the framework for building regulations in South Africa, and it is essential that all construction work adheres to these standards. The aim of SANS 10400 is to ensure that buildings are safe, healthy, and sustainable, while also protecting the environment and preserving our natural resources.
Construction laws in South Africa are also closely tied to building regulations, and it is a legal requirement that all buildings be constructed in accordance with the SANS 10400 series. This includes both new builds and renovations, as well as extensions and alterations to existing buildings. Building contractors, architects, and engineers are all responsible for ensuring that their work meets these regulations, and failure to do so can result in legal action and penalties.
The SANS 10400 series covers a wide range of topics, including the construction of walls, roofs, and foundations, as well as the installation of electrical and plumbing systems. It also covers fire safety, ensuring that buildings are equipped with fire alarms, smoke detectors, and fire-resistant doors, among other things. Additionally, the series provides guidelines for energy efficiency, ensuring that buildings are designed and constructed in a way that minimizes their energy consumption and reduces their carbon footprint.
Another important aspect of SANS 10400 is accessibility for people with disabilities. The regulations outline the minimum requirements for buildings to be accessible, such as ramps, wide doors, and grab rails in bathrooms, making it possible for people with disabilities to use and enjoy the building.

Building regulations and standards play a vital role in ensuring the safety, well-being, and sustainability of buildings in South Africa. The SANS 10400 series provides the framework for these regulations, and it is the responsibility of all those involved in the construction industry to ensure that their work meets these standards. By adhering to SANS 10400, we can help to create buildings that are safe, healthy, and sustainable for everyone.
South Africa’s National Building Regulations (NBR) were originally produced as a set of functional guidelines for anybody building any type of structure. They were not intended to be prescriptive in terms of what people should build, but they do stipulate important dos and don’ts – many of which are in fact mandatory. So if you are planning to build, this is a document you should familiarise yourself with.
While the NBR are only available from the South African Bureau of Standards (SABS), sans10400.org.za has a mission to make it easier for the general public to understand what these regulations are and how they affect us all. If you want to know more about these important regulations, have a look at the drop-down menu under SANS 10400-NBR (SA). Each of the regulations listed here is published as a separate document by the SABS. The size of each published document and its cost can be found at the SABS Online Standards Webstore.
Please be aware that while the topics featured on sans10400.org.za are those found in the regulations, we have not duplicated the regulations. Instead, we have discussed the issues the regulations cover in easy-to-understand pages. Also, note that we are in no way associated with the SABS.

Construction Elements & more
We are constantly adding blog posts that relate to these chapter headings to provide our readers with further information. You will find these under the drop-down menu Construction Elements. Some of these posts include personal experience and/or case history-type articles that share what others have experienced in terms of the regulations. We have also included an A to Z Glossary of Definitions and Terms used in the NBR to help you understand the meaning of the various terms used in the context of the legislation and national standards.
We have a free downloads page where you can access various documents, including a variety of Department of Public Works Guidelines:
- The National Building Regulations and Building Standards Act. This is the original legislation published in 1977 that governs all building and construction work in South Africa. Various updates have been made since this time, and these are also available for download.
- Guide for Architects Concerning Drainage Water and Storm-water Drainage.
- Standard Electrical, Mechanical & Architectural Guidelines for the Design of Accessible Buildings including Facilities for Disabled Persons.
- Hardware sample list (guidelines for the required finishes etc. of hardware when submitting tenders).
- A “Norms Calculator” for quantity surveyors.
- Drainage Details that provide guidelines in the form of technical drawings covering most aspects of drainage.

Hi Koketso,
Yes you can have individual title deeds for houses that are built on one single foundation slab. These could be part of a Sectional Title or a Freehold agreement and each has their own set of rules. It depends on how the property is developed.
Single slabs are common in townhouse as well as for semi-detached houses. There a few factors that affect the decision to use a single slab; one is cost. If the developer is building a few units then it will be cheaper for him to throw a single slab and build the houses progressively. There is also a safety and stability factor. If the houses are close together and, if he were to throw the slabs at different times, he might undermine the first foundation slab when placing the second. So your foundation slab might be more stable as a single slab than if it is constructed seperately.
With a freehold property you own the house as well as the land it is built on, and each house has an individual erf number. The freehold owner has to pay his or her own rates and taxes, insurance, maintenance, and services including water and electricity. The scenario as far as a sectional title property is concerned is very different. Here you only own the house, and all outside areas are common property, even if it is fully walled. A freehold complex has a homeowners’ association that is set up to look after maintenance of the roads, security and communal areas within the complex. In addition to the laws and guidelines in the National Building Regulations, homeowners’ association normally have their own sets of rules that all homeowners are obliged to abide by.
Hi Prudence,
Even though there are National Regulations each local authority has it’s own way of handling applications. Here is a link to Cape Town’s “Land Use Management” page and here is the Joburg link to their “building_plans_approval.pdf”
I act on behalf of a client who is currently obtaining SDP approval
for a new development.
Part of his obligations are to produce a section 4 certificate
Please advise me exactly how to go about this and who will issue the
certificate.
Kindly let me have a copy of one if you have one.
Thank you. This matter is one of great urgency.
Regards
Prudence Miller
How do we go about obtaining a copy of the registered approved plans
of our house? We bought a house (in JHB) 1.5years ago and the plans
the previous owners gave us, does not seem to be up-to-date. It is
also not 100% complete, as it was plans prepared for building
alterations done in the ’70s, so certain areas are demarcated as
“existing building” only with no further details.
Secondly, if the registered plans are not the same as what the house
looks like now, what should we do? Do we have any recourse to the
seller?
good morning,everyone,
can anyone help…
We bought a house about 16 years ago and about 4 years ago had plans made up as the existing plans did not show the swimming pool,lappa and a tiny rondavel used as a laundry.
We have now been told.,,4 years after submitting the plans..(the council having lost our submitted plans on 2 occasions) (thank heavens I had receipts)… that we must destroy the rondavel and the lapa as they are too close to building line.
We were aware of this and had the request for relaxation letters from all neighbours signed and submitted with the plans.
A site inspector came and told me he didn’t foresee any problems.
To date other than the site visit we have not been contacted by council. We have been advised of their decision by the lady who did our plans.
She also told me that the person refusing to pass the plans said he is sick of people building and then trying to get plans. We bought this house with the problem buildings already there 16 years ago!!!! . (We were first time buyers and didn’t even think to ask for plans and the estate agent never suggested it eithor….i can only presume that legislation has changed as plans were not an issue on purchasing our home.
What is your opinion on this…do we have to comply and destroy these buildings or is there another route we can follow? I would really appreciate some advice.
The property was built about seven years ago and has been occupied by
the owner-builder for approximately five/six years as can be shown by
a study of the electricity account.
What regulations apply with respect to the sale of the house?
Can one give individual title deeds to houses build on one foundation
slab? with seperate but closely built walls? as well as seperate
roofs? MY CONCERN IS THE SINGLE SLAB? Please help.
The legislation is downloadable from our downloads site. You will have to download the original law + the amendment. You can also download the old SANS 10400. NOTE that the original legislation is incorporated in this document; you will need to compare the legislation (which is shown at the top of each part with the amendments – it’s a bit laborious, but it works). The new SANS are, I am sorry to say, only available for purchase from the SABS. I hope you come right – and apologies it has taken so long to get back to you. The glitch in our system is thankfully now sorted!
I would like to obtain the following document:
EF 003 Appendix B1 form
Thank you
To Whom It May Concern,
RE: THE FUNCTIONS, CODE OF CONDUCT AND JOB DESCRIPTION OF A ENGINEER.
It would be appreciated if you could help me with the following
question? I want to have a house built and I would like to know what
are the:
1. Functions and processes that the engineer is to carry out?
2. Does the engineer liaise and visually inspect (on site) with the
architect and contractor the plot/land for contours, soil conditions,
thus determining the plan of the structure and determining of the type
of foundation to be applied? (prior to commencement of building
oerations).
3. When and at which stages does the engineer need to inspect the
building operations?
4. If a problem should occur, due to negligence on the part of the
engineer, is the engineer covered by an insurance?
Thank you for your kind attention, and I look forward to your
response.
Best Wishes/Mit freundlichen Grussen
Good day
Thank-you for your useful website
kindly send me the link where I can download the latest building
regulations thank-you
I presume this would fall under Facilities for Disabled Persons Part S, and this has changed completely. I am not sure what the answer is. The quickest way to check is to go to an SABS library and have a look at Part S. The other issue is that your local authority may require you to get permission to run this type of business from home. You’ll need to check that with them.
My daughter is a psycologist and we believe she can not work from the residence so I decided to build for her a consulting facility adjacent to the residing house the issue now is: is it law that she must provide paraplegic facilities?
Pam, the National Building Regulations state that “any freestanding wall built with masonry, concrete, steel, aluminum, or timber or any wire fence that does not exceed 1,8 m in height at any point above ground level and does not retain soil,” is a form of minor building work. And minor building work does not require plans – as you will see if you click on the link above. However, you do still need to notify the local authority of minor building work, and they may require certain documentation to be filled out, including a site plan. Furthermore, some local authorities DO require plans for ALL walls and fences. Your best bet is to check with your municipality what exactly they require. Presuming your fence is below the 1,8 m height, point out to them that you are aware the project falls under “minor building work” in terms of the NBR.
Please can you tell me if I need to have plans passed or municipal approval to put a palisade fence between my property and my neighbours?
Thank you,
Pam
Venetia, In terms of rates, local authorities are supposed to regularly update their records in terms of what is on a property vs plans. But I think the reality is they are so short-staffed they generally can’t even cope with new building. (About six years ago I remember a building inspector coming to check on the buildings on a farm where we were living – so it does sometimes happen.) If you don’t rebuild the building, then you could apply for a reduction in rates. In terms of rebuilding, I think the NBR would require you to notify the local authority that you are going to rebuild (i.e. the same requirement as for minor building work). But you would need to be sure that the plans comply with the current NBR. Plumbing might be a problem because of improved standards. If anything doesn’t comply, I guess you would simply have to submit a rider plan. You would also have to do this if you wanted to change anything – the position of doors and windows for instance, or make it smaller or bigger. Converting the measurements shouldn’t be too much of a problem though brick/block sizes may not match. At the end of the day it will be up to your local authority to decide what they need. As the law states in regard to minor building work, you don’t need plans for “the erection of any building that the local council doesn’t believe plans are necessary for”.
Regarding the wall. Some local authorities want plans for walls and fences; other will allow walls to be built to a certain height. The best thing is to check with your local authority what is required. Their concern will generally be that the foundations are sufficient to carry the load of the wall, and that the wall is on the correct boundary line.
Hi i was looking at my house plan and noticed a building on the plan that is not there today. i remember it been there as a child. 1. am i paying rates for this building 2 can i rebuild this building on the same spot or will i have to have a new plan drawn up. this house was buildt in 1945 and the measurements are in inches. must i also draw up a plan for a boundery wall that i want to build
Jan, The Building Regulations don’t cover swimming pools directly, but they do cover storm water drainage in general. More specifically, SANS 10252-2 covers drainage installations for buildings. This includes the necessary gradients for storm water drains, and where and how they should be built.
Anyone building a swimming pool must ensure that the overflow drains to a natural watercourse, a storm water drain, or a surface water channel. Neither the overflow nor any water that is emptied during the backwashing process should be emptied on the street or to any other public place. It also may not be emptied onto someone else’s property.
SANS 10209 The design and construction of private swimming pools covers the layout, design and construction of private swimming pools. Appendices covering the use of trees near a pool, construction procedures, painting and pool maintenance are also covered in the standard. It does not cover the provision of heating equipment. In terms of drainage/water, the standard covers pipework and drainage outlets; control of water during excavation; pool inlets and outlets (i.e. flow of water in and out of the pool).
It sells for R213.00 and you can order it from the SABS web store.
John the SA National Building Regulations don’t specify this. I think it probably falls under the local authority. Try contacting your local authority for information. You could also phone the SABS and see if there are any standards relating to site boards. I can only find information about safety signage. Sorry I can’t be more helpful.
what is the wording and layout for a site board at a construction site please?
Hi, I would like to know what the rules and regulations are towards storm water drainage or the away flow there of when construction a swimming pool? If any how much provision must be made? Thanks Jan
I have written a concise book, which is very inexpensive, called Start and Run a Professional Bricklaying & Tiling Business, as well as similar titles about concrete work and plumbing. The three are similar, but each with a different focus. I will let you know when they become available – it will be soon.
