Modular = Building = Permit Required
There's no special exemption for modular homes in most European jurisdictions. Once a structure is intended for permanent habitation, building permit regulations apply.
This applies regardless of whether the building:
- Was prefabricated in a factory
- Is technically transportable
- Sits on a slab or point foundations
Key Permit Requirements
1. Zoning Compliance
Local zoning plans determine what can be built where. Key factors include:
- Land use type: Residential, mixed-use, agricultural, etc.
- Building coverage: Maximum footprint as percentage of plot
- Floor area ratio: Total allowed floor space
- Building type: Detached, semi-detached, row house
- Height limits: Maximum building height
- Roof form: Some areas prescribe specific roof types
2. Urban vs. Rural Areas
In urban areas (within established building zones), construction is generally permitted if it fits the local character and meets regulations.
In rural or green-belt areas, building is often restricted. Only privileged uses (agriculture, renewable energy) may be permitted without special justification.
3. Technical Documentation
Permit applications typically require:
- Site plan and building drawings
- Structural calculations
- Energy efficiency documentation
- Fire safety concepts (where applicable)
- Drainage and utility connections
The Permit Process
| 1. Pre-application inquiry | Optional: confirm basic feasibility with local authority |
| 2. Prepare documentation | Drawings, calculations, energy reports |
| 3. Submit application | Through licensed architect/engineer |
| 4. Review period | 4-12 weeks depending on jurisdiction |
| 5. Approval | May include conditions or modifications |
Special Cases
Tiny Houses & Small Buildings
Very small structures (typically under 10-15 m²) may be exempt from full permit requirements in some jurisdictions — but only if NOT used for permanent habitation. Any dwelling use triggers permit requirements.
Temporary Structures
Genuinely temporary installations (seasonal, under 6-12 months) may have simplified regulations, but permanent or semi-permanent placement always requires proper permits.
