Seems obvious doesn't it, but you would be surprised how many structures are built without approved plans.
One step further, if you make changes during construction, make sure an amended plan is approved.
I visited a clients home today, they have sold and it appeared that there where some issues with what had been built compared to what the approved plans show.
A 2 level home on a sloping plot, it's double storey to the street, but single storey at the back. Garaging, entrance and some staff quarters are on the lower level at the front, the main house on one level above. The plot slopes upward from the street to the rear.
A plan had been approved for additional garaging, quite large, at the lower level, and an additional living room above, with a large outdoor entertainment deck and pool.
What was built was two living rooms on the upper floor, extending much further into the deck, with a smaller entertainment deck - more a balcony. The roof had been extended right over the balcony where before the entertainment deck was not roofed.
This was built ten years ago, and in that time, the national building regulations have been re written, a new regulation dealing with energy efficiency and insulation has been introduced, and the local authority has updated its zoning scheme regulations changing all the building line parameters.
A building line is an imaginary line, inset a certain distance inside the plot boundaries, over which you shouldn't build. In Cape Town, this varies according to the plot size.
In order to submit a plan to correct this now, the plan must comply with the regulations in place now.
The building line setback from the boundaries has increased in the new zoning scheme, so the structure as built is over the building line. To make things worse, historic building line restrictions are entrenched in the title deed, it's quite an old property, and the structure is in fact over these as well. So both a departure from the zoning scheme will be required to be approved, as well as a waiver of the title deed restriction.
Both of these will require consent of neighbours in a 360 degree circle around the house, approval of the variance, and can take 2 - 3 months in the process at least.
As in anything which requires permission to depart from a regulation, it is implied that this can be declined, otherwise, what's the point of the regulation!
UPDATE. The city's current interpretation of the title deed conditions, is that the wording does not allow, in the Table View area at least, a simple waiver of the title deed condition. They are currently requiring the title deed condition to be removed. This is a process that can take a year and cost any where between R 100K and R 250K. Seriously inconvenient !
This has come up now because the owner has sold, and with good advice from his estate agent, a sensible purchaser wants to see confirmation the house as built is properly approved. The fact that it isn't could seriously delay registration of transfer or even cause the sale to fall through.
Furthermore, back in the day, the design principle was, more glass more light! But in this day and age, the energy efficiency regulations recognise that glass is a lousy insulator and the maximum area of glazing is restricted relative to the floor area of the space. It very often happens that something designed and built ten years ago, would not now comply with the current regulations.
With the original approved plan, would have been an engineer design for the concrete deck between the garage below and the structure above. This would have taken into consideration the position of the walls above and been reinforced to take the weight of the structure at that point. But in this case, the walls, and roof structure above are in different places. You would hope that the engineer was advised and his design amended, but there is nothing visible to show that this is so.
This work was done for / by a previous owner. The current owner bought the house like this, but didn't check the approved plans when he bought. However, the current registered owner is held to be responsible for this by the local authority.
To make matters worse, we have to declare that this is an unauthorised, as built structure. The first thing a council planner does is check the aerial view of the site, and it is quite clear that the work we are now submitting plans for is already there. Council, in this case is fully entitled to levy a fine for unauthorised building work, a % of the value of the work ( at current rates ).
The message is. that either building without plans, or winging changes and variations on site, can have dire consequences. When you buy a home, make it a condition that the seller proves that all structures on the site are legally approved, so that, as in this case, it doesn't become your problem and responsibility. This includes boundary walls, pools, thatched gazebo's, covered patios. If it has a roof, or requires a foundation, it needs a plan !
If the pool guy says he will organise the plan, ask for a copy before they start digging the hole.
Last thing, when construction commences you should call the building inspector to check the setting out of the new work. You should also call him on completion to sign off and provide an " occupancy certificate. This states that he has checked and that this is complete as per the plan approved. He may ask to be called at other key points during construction, if that the case he will advise what he needs. Plumbing installation for instance might require an inspection. The inspector, on completion would require certificates of compliance from engineer, electrician, plumber, and in the case of the energy efficiency regulations very probably one from your architectural professional.
I could quote many examples of where unauthorised work has had serious consequences. I had one client, who decided that a nice vacation project - in 30 degree southern hemisphere Christmas conditions, in sandy soil, would be to sink a cellar behind his house. he got some labour in and managed to undermine the foundations of his house causing it to almost fall into the excavation. No plans - no engineer, and not much in the way of common sense !!
Proper plans first, properly designed, by a professional to see that they comply with all requirements practical and technical ! It can save you a fortune in the long run.
