Want a dormer on your Amsterdam canal house? One permit will soon do

From 26 November, renovations in Amsterdam's protected historic areas need one permit instead of two, and what you add is judged together with what you take away.

Renovating a home in one of Amsterdam’s protected historic areas is about to take one permit fewer.

From 26 November, tearing out part of a building as part of a renovation, such as cutting into a roof for a new dormer window, no longer needs its own demolition permit.

It will be handled inside the ordinary building permit instead.

Two permits for one job

Until now, owners in protected cityscapes needed a demolition permit for what came out and a separate building permit for what went in.

The heritage check sat with the demolition permit, so the city could weigh the value of the old roof but had no clear way to judge the dormer that replaced it.

Under the new rule, both halves are judged together: what is removed and what comes back in its place.

The city calls it a reduction in red tape for the owners concerned.

What stays the same

Tearing down a whole building in a protected area still needs a separate demolition permit.

A building permit is refused if the work would do disproportionate harm to the protected cityscape.

Buildings with an extra heritage label, such as the most protected buildings in the city centre and buildings that define the look of a street, are also judged on their own historic and architectural value.

The rule covers both nationally and municipally protected cityscapes.

When it starts

The mayor and aldermen adopted the change on 20 October, and it was published in the Gemeenteblad, the city’s official gazette, on 28 October.

It takes effect on 26 November.

Anyone with a stake who wants to challenge it can appeal to the Council of State until 9 December, but an appeal does not stop the rule from taking effect.
