The PAJA: A Law to Protect Your Rights

DeptJusticeHeader The PAJA: A Law to Protect Your Rights

We get questions daily about buildings blocking views, balconies overlooking neighbours’ bedrooms, building approval without neighbours’ consent, developers not putting in correct storm-water drains; complaints that the neighbours wall is on “my” property; the list goes on and on. People also want to know who they can contact to find out what the situation is, who approved the plans (if indeed they were approved), and how and why their neighbours are “getting away” with these activities. The good news is that there is a law in South Africa that was published in 2000 – The Promotion of Administrative Justice Act, 2000 (Act 3 of 2000) – that was promulgated to protect you.

The Promotion of Administrative Justice Act (PAJA)


DofJ s The PAJA: A Law to Protect Your Rights>





This piece of legislation is not well known, and it is there essentially to ensure that the government (and all its departments) act in a fair way when decisions are taken that might affect any individual. It is your basic human right to have just, fair and equitable administrative action.

The South African Constitution guarantees that any action taken by any administration in South Africa has to be reasonable, lawful and must follow procedures. It must also be fair in relation to all concerned.

The law covers all levels and all departments in all the provinces:

  • Departments at national, provincial or local government level,
  • The national, provincial and local legislatures,
  • The national and provincial executives,
  • The judiciary (or courts),
  • ‘Parastatals’ such as Eskom and Telkom.

We will refer to those that deal with building regulations and the building by-laws in South Africa.

Allowance has also been made for anybody to ask for an explanation from any of the government or municipal departments regarding why they made a certain decision. You also have the right to request reasons as to why a certain decision was made that negatively affects you. The law states that it is your right to ask for reasons and they cannot refuse you this right.

It is important to note that these requests and replies should all be done in writing. If you are given verbal response it’s you prerogative to accept it, but if you aren’t happy, you have every right to demand that it is given to you in writing. Of course it is always best to have this type of thing in writing, particularly when there is a substantial dispute.

The PAJA addresses the fact that if after reasons have been supplied there is still disagreement. If this is the case, then provision has been made for a review of “the administrative action” by a court or a tribunal.

Once you have identified something you are not happy with (either issues mentioned above or other problems you are facing) that you feel that the relevant department should have consulted or informed you about, you must follow the correct procedures:

  1. Request the reasons, in writing, from the department that made the initial decision. This must be done within 90 days of finding out the decision has been made. If you are not satisfied with the reasons given then…
  2. You must use the internal appeal procedure for that department (see below), if they have one. Not all departments have an internal appeal system. If they don’t you can then…
  3. Go to court (see below)
  4. Use other remedies (see below)

To help you we have two pdf documents as guidelines when making requests:

Form to request reasons PDF

Form for Prior Notice PDF

I want to request reasons for what has been allowed—What do I do?

Firstly and most importantly your request must be in writing. State clearly, with reference details, which decision your request is for. Next say why you think the decision that they made is wrong. You must include all your details including your full name, postal address, email, telephone/cellular phone contact details and/or fax number. Your letter can be sent by post, fax, email or delivered by hand. Make sure that you send faxes or emails to the correct address or number. It might be best to deliver your request so that you get a signature and proof of delivery. If you do deliver by hand, get a signature and full name of the person who takes the letter, and include the date and time next to the signature.

How will they respond? What reasons will they give?

They must not try to persuade you that their decision was the correct one. What they must do is give you a clear reason why and how they reached their decision. All your questions that you asked must be answered.

How long will they take to respond?

They must give you a satisfactory reply within 90 days of receiving the request.

Can they tell me the reasons over the phone?

All reasons should be in writing, unless you accept reasons given to you verbally. If not you have full right to ask them to please put their response in writing.

What is the appeal process? How does it work?

There are a few departments that have the facility for an internal appeal. If the department you are dealing with has such a procedure then you have to use this first before you can consider further action. Again you will have to put your demand in writing and say that you are not satisfied with the reasons given to you up until now. Then you request that the matter be taken to the relevant appeal section. The next step is to go to court.

How do I take my case to court?

If you are not satisfied with the reasons given to you by the appeal division, or if there is no appeal board, then you can take the matter to court. You must ask a court to review your case within six months of the internal appeal, or if there is no internal appeal, within six months of the decision. Unfortunately though the court review can be costly.

Are there any other cheaper options?

The internal appeal (if there is one) is usually free.

There are a few other options such as:

  • Asking a political party in your area to help,
  • Putting your complaint to the Provincial MEC for that particular department (eg the local authority’s planning department),
  • You can find out who the Minister is, and who is responsible for that department, and write to him/her and explain your problem.
  • There are quite a few non-government organisations (NGOs) that you could ask for help. These are usually free.
  • Paralegals are there to assist people in awkward situations.
  • If you suspect that there has been any corruption involved in a decision that affects you, then you can call the public protector and give them all the details. The toll-free number is 0800-112-040
  • There are legal aid boards and justice centres in most of the major centres that will assist you free of charge. You can ask the legal aid officer at your nearest court to arrange a lawyer, free of charge, to assist you. You can also call the legal aid board on 021-481 2700.

Regulations for Lightning Conductors on Thatch Roofs

Thatch house lightning Thatch Roofs and Lightning

Thatch roofs are most susceptible to be set alight by lightning than any other roof type. For the protection of the public and property the South African National Standard 62305-3 was introduced in 2011.

SANS 62305-3: Protection against Lightning (published in 2011) is drawn from an international standard, IEC 62305. Part 3 deals with “physical damage to structures and life hazard”.

Remember that anything related to electrics must be dealt with by a qualified and registered electrician.

Introduction to the Regulations for Thatch Roofs and Lightning

This part of IEC 62305 deals with the protection, in and around a structure, against physical damage and injury to living beings due to touch and step voltages.

The main and most effective measure for protection of thatch structures against physical damage is considered to be the lightning protection system (LPS). This usually consists of both external and internal lightning protection systems.

An external LPS is intended to:

  1. intercept a lightning flash to the structure (with an air-termination system),
  2. conduct the lightning current safely towards earth (using a down-conductor system),
  3. disperse the lightning current into the earth (using an earth-termination system).

An internal LPS prevents dangerous sparking within the structure using either equipotential bonding or a separation distance (and electrical insulation) between the external LPS components and other electrically conducting elements internal to the structure.

The main protection measures against injury to living beings due to touch and step voltages are intended to reduce the:

  1. dangerous current flowing through bodies by insulating exposed conductive parts, and/or by increasing the surface soil resistivity,
  2. occurrence of dangerous touch and step voltages by physical restrictions and/or warning notices.

The type and location of an LPS should be carefully considered in the initial design of a new structure, thereby enabling maximum advantage to be taken of the electrically conductive parts of the structure. By doing so, design and construction of an integrated installation is made easier, the overall aesthetic aspects can be improved, and the effectiveness of the LPS can be increased at minimum cost and effort.

Once construction work on a site has started, access to the ground and the proper use of foundation steelwork for the purpose of forming an effective earth-termination, may well be impossible. Therefore, soil resistivity and the nature of the earth should be considered at the earliest possible stage of a project. This information is fundamental to the design of an earth-termination system and may influence the foundation design work for the structure.

Regular consultation between LPS designers and installers, architects and builders is essential in order to achieve the best result at minimum cost.

If lightning protection is to be added to an existing structure, every effort should be made to ensure that it conforms to the principles of SANS 62305-3. The design of the type and location of an LPS should take into account the features of the existing structure.



Specific requirements for an LPS in structures dangerous to their surroundings due to the risk of explosion are under consideration. Additional information is provided in Annex D for use in the interim.


This part of IEC 62305 is not intended to provide protection against failures of electrical and electronic systems due to overvoltages. Specific requirements for such cases are provided in IEC 62305-4.


Specific requirements for protection against lightning of wind turbines are reported in IEC 61400-24 [2].

Planning House Extensions

Whether you are building a new home or planning house extensions to an existing home, you are going to need building approval from your local authority. Even if you are simply opening up a wall or partitioning a room by erecting a new internal wall, most councils will insist on working drawings.

VDM front door1 Building Extensions

A self contained flatlet has been added on over an existing double garage and a patio created on the flat concrete roof over the front entrance hall.

They won’t worry about issues like matching materials or style, but they will consider all the elements that relate to building codes and building standards.

Extension Options

There are various ways that you can extend an existing house. For instance you can go up and create a second storey or opt for a more straightforward lateral extension. If the pitch of your roof is sufficient, you might be able to convert this into an attic room. Alternatively you could add a separate freestanding structure with a link to your existing house.

Having said that your local authority isn’t going to be bothered with style, this is an element that is essential if the extension is going to look good. Materials should also match or look as though they have been chosen carefully. This means that if yours is a facebrick dwelling, the extension should be built using the same finish facebrick. If it is plastered and painted, it is best to match the paint colour. This isn’t always as easy as it might seem, since paint colors fade and from time to time manufacturers change their specifications.

Planning for a Building Extension

Sometimes, but not always, people do plan for future extensions. This makes it a lot easier when it comes to adding on a room or converting space. As an example, where a future door is planned, building in a lintel at this point, and enclosing the door area with straight joints will make it easier to knock out the brickwork at a later stage. The fact that the bricks aren’t bonded beneath the lintel won’t be an issue, because the lintel will support those above.

Even so, you will need to be sure that the extension is correctly executed, with the correct foundations (unless of course you are going up, in which case you will need to have existing foundations that can take the weight of the new building extension), and where brick or block walls meet, these will need to be bonded, or joined in such a way that cracking will not affect the structure.

Types of House Extensions

These include:

  • building a core house and then adding to it later according to existing plans
  • converting a garage into extra living space
  • converting an attic into habitable space
  • constructing rooms in a roof where there is no existing attic
  • adding or converting a cellar
  • adding a conservatory, sunroom or pool room, usually with glass
In all instances it is essential to ensure that your new house extension complies with building standards.

Develop a Core House

If you are building and you don’t have the means to build the size house you believe you need, an excellent solution is to build over a period of time. Thoughtfully designed, it will never look incomplete.

Below are three drawings that show how a core house (coloured yellow) may be added to over time.Build Stage1A s Building Extensions

In the first drawing, you can see that it is a simple, compact two-bedroomed home. Both bedrooms share a bathroom and they are both the same size. Each room has built-in cupboards and there is a laundry cupboard in the passage outside the bathroom. The living area is open plan, with a bar counter “dividing” the living space.






Build Stage2A s Building ExtensionsIn the second drawing, the kitchen has been extended, in such a way that existing plumbing is used, even though the sink changes position. An exterior door is added, linking to a courtyard with a washing line, and to a double garage. One section of the garage incorporates a storeroom, adjacent to a loo with a basin, accessible from the courtyard.  The main bedroom is also included in this phase, although it could, of course, be built on later, since it is at the opposite side of the house. An en suite bathroom and more substantial cupboards are also included in the new plan.















In the third drawing, an open-plan lounge-dining room has been added (blue), along with a new entrance way and a guest loo. A swimming pool has also been included on the plan, though this could also be a separate phase.Build Stage3A s1 Building Extensions

Convert a Garage

This can be a very convenient and reasonably easy way to extend a house, although local authorities are usually strict in terms of upgrading the existing finishes. For instance you may need to have a ceiling installed, and lighting and ventilation might need to be upgraded.

Add a Sunroom, Pool Room or Conservatory

There are companies that specialize in glazed structure (or one where a polycarbonate material is used) that fit this category, though you can also have something designed and custom built.

Go into the Roof

Many older homes were built with attics that were intended to be used for storage. You might need to add windows and insulate the walls and ceilings to make the space habitable.

If there isn’t an existing attic, and the roof is high pitched enough, you might consider building a room in the roof space. The basic concept is very similar to converting an attic, although structural alterations will be considerably more complex. If the pitch is not sufficient, you will have to extend the gable ends and increase the pitch of the roof.

In both instances you will probably have to add stairways that are easy to use.

In South Africa and other hot-climate countries, the roof space (and attic) in a house can become unbearably hot, so it is essential to pay attention to insulation.

Go Underground

Cellars are surprisingly uncommon in South Africa, but they are sometimes included in the design of a house, and may be added at a later stage providing the foundation walls are high enough. Generally it is easier to add a cellar where the house has been constructed on a slope.

Just remember that for a cellar to be converted into a habitable space (even if only as a playroom), it must be totally dry (there must be a damp-proof membrane between the brickwork and the soil beneath ground level) and have sufficient light and ventilation. Usually this will entail installing artificial ventilation and electric lighting.
