Do I need a permit for a garden home (mantelzorgwoning)?

Often not. In many Dutch gardens, a garden home (mantelzorgwoning) may stand in the back garden without an environmental permit (omgevingsvergunning). That is why this type of housing works: you do not have to wait months for a decision before anything can happen.

But there are two tests that run side by side, and they are often confused. The first concerns the building: may this structure stand here. The second concerns its use: may someone live in it independently. The answer to one says nothing about the other.

Two questions, two answers

When it can be permit-free

Five conditions come back in almost every municipality (gemeente). All five must be met, not four out of five.

• It stands in the back garden area (achtererfgebied), behind the front building line (voorgevelrooilijn) of your home.
• The floor area stays within the space your property allows. How much that is depends on the size of the property and on what is already there in the way of sheds, extensions and canopies.
• The height suits the distance to your main building; close to the house it may be higher than further down the garden.
• It is ground-based and has one storey, so single-level and on the ground.
• There is a genuine informal care relationship, as defined in the Wmo 2015 (Social Support Act). Many municipalities ask for a statement from a GP, district nurse or social medical adviser to support this.

When you do need a permit

There are six situations in which you take the application route. Four of them have to do with your plot and two with what applies to it.

• The home is larger than what may be placed on your property without a permit.
• The property is already full of existing buildings that count towards the limit.
• The spot is outside the back garden area, for example next to or in front of the house, or in a side garden facing the street.
• Use as a self-contained home is not permitted in your municipality's environmental plan.
• Your home is a listed monument or is in a protected townscape or village conservation area (beschermd stads- of dorpsgezicht). In that case much of the permit-free scope lapses, including for outbuildings behind the house.
• The plot is in the rural area (buitengebied), where municipalities more often set additional rules about the location, how it fits into the landscape and removal once the care ends.

Needing a permit is not a refusal. It is a procedure with a decision period, and we take care of that application. How it works is explained in how to apply for a permit.

Why your neighbour got a different answer

This is the most frequently asked follow-up question, and the answer lies in three things that differ per plot.

The size of the property. What may be placed there is linked to how large your back garden area is. Two gardens that look the same size can differ because the front building line runs differently or because part of the plot does not count as back garden.

What is already there. A shed of twenty square metres, a canopy and an extension all count. Your neighbour with an empty garden simply has more space left than you do with a full one, on the same size of plot.

The municipality. The environmental plan is local. Municipalities may set their own rules on dimensions, siting and use within the national framework, and they do. Two plots ten kilometres apart can work out differently with the same design.

That is why no rule of thumb from the internet works, not even the rules of thumb that are correct in themselves. What does work is retrieving the rules for your own address.

Which rules are different in the rural area

Outside built-up areas, additional rules apply more often, and they are rarely more lenient. Municipalities there focus on keeping the landscape open, on limiting increasing development (verstening) and on preventing extra homes in the rural area.

In practice you will come across three things there. A stricter limit on where on the plot you may build, usually close to the existing buildings and not out in the field. Requirements for fitting into the landscape, for example planting all around. And the condition that the home is removed as soon as the care stops, sometimes laid down in an agreement with the municipality.

If the plot has an agricultural zoning, there is one more factor: the question of whether living there is allowed at all. That is a conversation with the municipality before you choose a home, not after.

Rules that are often forgotten

The discussion is usually about square metres. These five points only come up later, and then they cost time.

• If you rent the main home, you need permission from the landlord, regardless of what the municipality thinks.
• Ground lease (erfpacht) or an owners' association (vereniging van eigenaren) can impose their own restrictions that have nothing to do with the environmental plan.
• The utility connections. Water, electricity and sewerage are usually linked to the main home. A separate connection can bring additional requirements.
• Rainwater. More roof means more drainage, and a number of municipalities set requirements for collecting it on your own land.
• Trees. If something has to go to make room for the home or to get the crane in, a separate permit may be required for that.

Buying without a permit

This is a common search, and it contains a flaw in reasoning. You can always buy a garden home; buying is an agreement between you and the supplier, and no municipality is involved. Where it goes wrong is when it is placed.

So the order matters more than the question. First do the permit check for your address, and only then sign anything. If you do have to sign earlier, have it written into the agreement that you can withdraw while the permit assessment is ongoing. That is the most important of the eight questions to ask about a quote, and it is the one asked least often.

What happens if you go ahead without one

Municipalities enforce inconsistently and usually in response to a complaint. If a report comes in, an inspection follows and, if there is a breach, first a letter with a deadline. After that an order subject to a penalty (last onder dwangsom) may follow: you are given a period to resolve it, and for every week or month that it continues you forfeit a sum of money.

What happens then depends on whether it can be legalised. If the home does fit within the rules after all, or a permit can be granted for it, it is a matter of putting the paperwork right. If it does not fit, a demand for removal comes on the table, and that is an expensive lesson for something that would have taken ten minutes beforehand.

How to get certainty

Three steps, in this order, and together they cost little.

• Do the check for your address. It retrieves what applies nationally and what your municipality has added on top, and shows where the two differ.
• Ask the municipality for preliminary consultation (vooroverleg). Many municipalities offer an informal conversation or a draft request, during which the clock of the procedure is not yet running.
• Have the answer confirmed in writing. Even if it is permit-free. That is your file if a neighbour calls years later.

The other municipal rules you may run into are covered further down this page. How to choose the spot in the garden is explained in placing it in your garden.

What the municipality wants to see from you

If a permit is needed, the municipality will usually ask for a site plan of the plot with the home drawn in, for floor plans and elevations with dimensions, and for evidence of the care relationship. With us you can download the floor plan of each model as a PDF, with dimensions in millimetres, so you do not have to have that document drawn up yourself.

Even if it is permit-free, it is wise to notify the municipality of your plan and have the outcome confirmed in writing. That costs you an email and it prevents an enforcement letter prompted by a neighbour who sees things differently. How the application itself works is explained in how to apply for a permit.

How long permission takes

If it is permit-free, there is no waiting time: you do not need a decision to be allowed to start. In practice, all that remains is the notification for the technical part, no later than four weeks before building starts.

If a permit is needed, most applications have a decision period of eight weeks, which the municipality can extend once by six weeks. For a plan that departs significantly from the environmental plan, an extended procedure may be needed, and then it can take up to about six months. After the decision there is also a period in which interested parties can lodge an objection.

Those weeks do not have to be lost time. With us, the application runs in parallel with the design and construction of the home, so nothing stands still. The full timeline is explained in how long building takes.

Permit-free does not mean requirement-free

One misunderstanding is persistent. Not needing a permit means that the municipality does not check your plan in advance. It does not mean that the technical building requirements no longer apply: structure, fire safety, ventilation, daylight and insulation apply in full. It is just that nobody comes to check. This is set out in does a garden home have to comply with the building regulations (Bouwbesluit).

What happens under the rules when the care stops

The exception for informal care is linked to the care situation. When that ends, the home may not simply continue to be lived in as a self-contained home. In practice there are three ways out: the home is given another use that is permitted, for example as a guest house, the home is moved, or the home goes back to the supplier. We buy back our own homes, so that way out is guaranteed with us.

What we do

We find out in advance what your municipality's position is, and if a permit is needed, we take care of the application, including drawings and supporting evidence. It runs in parallel with the design and production, so you do not lose those weeks twice.

Start with the permit check. It takes ten minutes and determines whether you are looking at the short or the long route, and which models are an option at all.
