Applying for planning permission for your dormer — steps

Step 1 — Permit Check

Open the Omgevingsloket (omgevingswet.overheid.nl) and do the Permit Check (Vergunningcheck). You fill in:

• Address of the house
• Works (choose 'place dormer')
• Location on roof plane (front/rear/side)
• Dimensions and height
• Particulars (monument, protected cityscape)

The check indicates per activity whether a permit/notification is needed. Save the outcome as a PDF — handy as a later burden of proof.

Step 2 — Pre-consultation (optional but smart)

For plans sensitive to aesthetic review (welstand) (almost always the front), a pre-consultation (vooroverleg) pays off. Request it at the building counter of your municipality. What you submit:

• Sketch drawing (no full building drawing required)
• Photos of current situation + photos of reference dormers
• Short motivation (why, how it fits into the street)
• Intended material and colour

Within 2–6 weeks you will receive a response: positive, positive provided adjustments are made, or negative. Adjust if necessary before you formally submit.

Step 3 — Preparing application documents

For the definitive application you need:

• Building drawings (situation 1:1000, floor plan 1:100, facades 1:100, cross-section 1:50, details 1:5/1:10)
• Structural calculation of the trimmer construction (raveelconstructie)
• Photos of current situation (facade, roof plane, adjacent buildings)
• Material and colour charts
• Ownership details (cadastre)
• Possibly acoustic or thermal calculation in special situations

Are you working with a dormer company? They usually deliver this ready-made as part of the quotation.

Step 4 — Submitting via Omgevingsloket

Submitting itself:

1. Log in with DigiD (private individual) or eHerkenning (company). 2. Choose the activity(ies): environment plan activity (building) and possibly building activity or building notification. 3. Upload all documents (PDF). 4. Fill in construction costs (basis for municipal fees/leges). 5. Send and receive the acknowledgement of receipt.

From the confirmation, the decision period of 8 weeks starts. The municipality can send a request for additional information (aanvullingsverzoek) — the period then pauses until you supplement. Supply additions quickly to limit delays.

Step 5 — Decision and objection

Within 8 weeks (possibly +6) you will receive the decision:

• Granted: publication on officielebekendmakingen.nl. From publication, a 6-week objection period runs for interested parties (especially neighbours).
• Refused: motivation is stated in the decision. You can adjust + reapply, or object.
• Granted under conditions: permit is valid provided you process the mentioned adjustments.

To wait for it to become irrevocable or not? Legally you may start after granting, but until the end of the objection period this is at your own risk. With a well-founded objection you must reverse it. For certainty: wait 6 weeks after publication.

Tips to prevent delays

• Request a pre-consultation with aesthetic review (welstand) before the formal application.
• Submit all documents at once — requests for additional information pause the time limit.
• Communicate with neighbours before you submit. A neighbour who co-signs (no objection) effectively speeds up the planning permission.
• Fill in construction costs realistically — too low a statement can lead to an additional assessment.
• Save the outcome of the Permit Check as proof for later sale.
• Check the municipal fees ordinance (legesverordening) of your municipality before you submit — with large differences between construction costs this can make a big difference.

Frequently asked questions

Short, honest answers to frequently asked questions.

Can I do the application myself?

Yes, the Omgevingsloket is accessible. With custom work or plans sensitive to aesthetic review, a professional is often more convenient.

What does an application cost?

Municipal fees (leges) vary by municipality: fixed amount (€200–€600) or percentage of construction costs (0.5–3%). Drawing work and structural engineer are on top of that.

How long does the procedure take?

Regular procedure: 8 weeks + possible 6 weeks extension + 6 weeks objection period. Total ~3–5 months for certainty.

What is the difference between biological building notification and environmental planning permit?

Building notification is a notification without prior testing (only technical); environmental planning permit is a real assessment (spatial + aesthetic review).

Do I need to have DigiD?

Yes, for private applications via the Omgevingsloket. Without DigiD you cannot submit.

What if I want to withdraw the application?

That is possible via the Omgevingsloket until the decision is made. Fees are usually not (fully) refunded.

Can a neighbour object?

Yes, during the 6-week objection period after publication. The objection goes to the municipality's objections committee.

What happens with permit-free building without building notification?

No notification is not a problem for many minor interventions; for dormers that fall under the building notification obligation, the municipality can still enforce.

May I start before the objection period expires?

Legally you may after it is granted, but with a well-founded objection you must reverse the work. Waiting is usually safer.

How do I know if my application is complete?

The Omgevingsloket checks formally; substantively the municipality does that in the first weeks. A request for additional information follows if something is missing.

Summary

The application starts with the Permit Check on the Omgevingsloket. For plans sensitive to aesthetic review (welstand), a pre-consultation is smart. The formal application consists of building drawings, structural calculation, photos and material charts. Regular procedure: 8 weeks to decide, 6 weeks for objection. With good preparation and an experienced builder, the process is completed in 3–4 months.
