ᐅ Permeable Pavements in the Building Permit / Planning Permission Application

Hello everyone,

What is the significance of permeable traffic areas in the building permit / planning permission? In our case, for example, the terrace is specified as made of water-permeable material, and for the driveway / access road, the building application lists "permeable eco-paving" (which is not required by the zoning plan). What happens if I want to use impermeable material instead? Regarding the floor area ratio and similar regulations, I believe it should not matter since everything counts there, even if grass is used for the driveway, as far as I know. The floor area ratio is being complied with; I am just uncertain about the permeability requirement.

Can someone help me with this?

Regarding the floor area ratio, I am also interested in who needs to apply for or approve changes if, later on, a larger paved area is planned than initially stated in the building permit / planning permission?

Can anyone explain how the information in the building permit / planning permission application works when permeable materials are specified for the driveway or terrace, or even something specific like eco-paving, but later you want to use a different, sealed material? Do you then have to submit another kind of application?

Also, who is responsible for calculating the floor area ratio, wastewater fees, etc., afterward? The area is different after about six months compared to what was initially planned in the building permit / planning permission, since not everything can be exactly as planned when designing the driveway or similar features later on.

Your building permit is basically binding. In my opinion, you cannot simply make changes afterwards. You would need an amendment to the building permit application – that is what it is called here – which cost 90€ and takes about half the time.

1) Yvonne is right. It is legally binding.
2) Who enforces this? Usually no one. Unless a neighbor complains. Then, of course, authorities have to take action.
3) ----and what would happen then? In the worst case, a demolition order. Or a small fine. Or a request to apply for a retroactive building permit / planning permission if it’s a minor issue. Example: Mr. S. owns a 600 sqm (6,458 sq ft) plot with a floor area ratio of 0.25, which gives him the right to build 150 sqm (1,615 sq ft). The house is 10 by 13 meters (33 by 43 feet), which equals 130 sqm (1,400 sq ft). That is not enough for a terrace and driveway, as only 20 sqm (215 sq ft) remain. He decides to apply for a 20 sqm (215 sq ft) terrace and present the rest as a gravel surface bound with water. The path to the front door is then considered an impermissible floor area ratio exceedance. Mr. S. now doesn’t care at all, paving the driveway generously with asphalt, making a large terrace from concrete pavers in lean concrete, and also constructing a wide path to the front door. It’s raining cats and dogs. Buckets of water run off Mr. S.’s property onto the neighbor’s land. The neighbor’s plants are washed away, etc. The neighbor talks to Mr. S., who is completely uncooperative, saying, “What do I care about your bushes?” The neighbor gets angry – and now there could be trouble with the building authority, because the neighbor says, “No, I won’t accept this.” Specifically, in our area there has already been a case where the building authority stopped excessive paving because a neighbor complained.

Regarding point 3)
That can really become quite expensive if you involve a lawyer and everything else.

Anyone submitting the building application should be able to understand development plans (including textual regulations) and should not include more in the application documents than what is specified in the regulations. What is stated there is considered agreed upon, and any covert subsequent changes may jeopardize the validity of the approval.

You can see this in the textual regulations. There is a wide variation between municipalities: some provide a table showing how different materials are counted in terms of height; others make no such distinctions but allow a 50% increase in floor area ratio for driveways and similar ancillary facilities.

So, our home construction company handled the building permit applications. We were not asked what type of paving or terrace we wanted – on the contrary, I even stated that the terrace should definitely be sealed, and the answer was that the application always lists it as permeable because the building permit only covers structures like the house and garage.

It’s as if you don’t have to specify the terrace at all. This seems contradictory.

What happens if you don’t include a terrace in the application and build one later? You don’t need a new permit or an amendment for something like that, do you? Why would it be an issue if something is stated in the application but built differently later on?
