Can I build a garden house without a permit?
In the back of the garden (behind an imaginary line 1m behind your house facade), max 30m² floor area, max 3m high (5m with gable roof), at least 1m from property line: permit-free. In the front, on a corner plot visible from public road, or in protected cityscape: always permit. In an apartment with VvE: VvE approval always required (separate from permit). Permanent residence not allowed — garden house remains an “outbuilding”. Fine for construction without permit: €1,500–5,000 plus possible removal order.

⚠️ Penalty if you do it anyway
€1,500–5,000 for construction without permit (depending on municipality and size). Municipality can require garden house removal (penalty €500–5,000 per week or administrative coercion). House sale later: buyer can require permit or legalisation. Land-use plan violation (permanent residence): additional fine plus eviction order.

❓ Frequently asked questions
Can I live or permanently overnight in my garden house?
Permanent residence: no. A garden house is an “outbuilding” without residential designation. Permanent sleeping or registering at the address: land-use plan violation plus fine. Incidental guest overnight (few nights/month): usually no problem. Airbnb rental: falls under the vacation rental regulation with separate permit.
Can I install electricity and water in my garden house?
Yes, in a permit-free garden house you may connect to utilities. Options: apply for own meter at network operator (Liander, Stedin) or extend from main house (no extra meter, lower cost). For solar panels on garden house: no permit needed.
Can I use my garden house as an office or workspace?
For own use without customer reception: yes. With receiving customers or employees: business-use permit may be needed, plus zoning, parking and environmental rules. For self-employed home office: usually free.
What if my neighbours object?
For permit-free construction: neighbours have no formal say, but complaints about view/shadow can lead to mediation (Beterburen). For permit procedure: 6-week objection period, can lead to permit withdrawal or amendment.
What's the difference between garden house, shed and log cabin?
Legally no distinction — all three are “outbuildings” and fall under the same rules (max 30m² permit-free in back, max 3m high). Shed: usually storage. Garden house: living space. Log cabin: wooden construction. Practical difference is in furnishing and use, not in permit.
Can I rent out my garden house as a separate rental unit?
No. The garden house is an outbuilding to the main residence, not a separate dwelling. For separate rental: land-use change + new building permit needed. Airbnb vacation rental: falls under the vacation-rental regulation of the main residence (counts in 30-night quota Amsterdam).
How much does a garden house permit cost if I need one?
Environment permit: fees €500–2,000 depending on municipality and construction sum (often 3% of building cost, minimum €500). Architect drawing: €500–1,500 extra. For permit-free construction: no costs. Tip: preliminary request (free) to test in advance.
What if the municipality wants to remove a permit-free garden house anyway?
When in doubt: apply for an “Environment permit for legal certainty” — you get written confirmation that no permit was needed. This document is your proof in future sale or dispute. Cost: ~€250–500 per municipality.
