Mobile halls and large tents: when is a notification sufficient and when is a building permit required?

Small structures (Appendix No. 1)

• Limits: built-up area ≤ 40 m², height ≤ 5 m
• Regulatory regime: usually no notification or building permit required

Simple structures (Appendix No. 2)

• Typically: up to 1000 m², height ≤ 5 m, limited purposes, temporary
• Regulatory regime: notification to the building authority

Other structures

• Exceed the limits of simple structures, have permanent foundations, connection to networks
• Regulatory regime: building permit pursuant to Section 211 of the Act

Source: Building Act No. 283/2021 Coll., Annexes 1 and 2

Briefly and clearly:

• Temporary, smaller halls up to 1000 m², height ≤5 m, up to 3 years, with temporary anchoring → notification is sufficient
• Larger or permanent halls with solid foundations or permanent connections → building permit
• Short-term rentals → usually no notification required

1. Built-up area and height

   Simple structures: ≤1000 m², height ≤5 m
   Overlap → building permit

2. Purpose of use

   Temporary storage, logistics, construction site, seasonal events → simple structure
   Permanent operation, production, accommodation → other structure

3. Duration of placement

   Up to 3 years → usually considered a temporary structure, suitable for notification
   3 years and longer → the structure may be considered a permanent structure → building permit

4. Anchoring and construction

   Demountable → notification
   Fixed/concrete foundations → building permit

5. Connections and infrastructure

   Temporary → notification
   Permanent (water, sewerage, gas, electricity) → building permit

6. Special restrictions

   Storage of hazardous substances → usually building permit
   Compliance with zoning plan → always required

Short-term rental includes situations where mobile halls and large tents are used for a limited period of time, for example for seasonal storage, exhibition spaces, or cultural and sporting events.

Main principles:

• Temporary nature of the structure: the structure must be demountable and mobile, without permanent foundations.
• Rental period: typically several days to several weeks. Longer periods → rules for simple structures apply.
• Purpose of the structure: temporary rental only; it must not be used for permanent operation or handling of hazardous substances.
• Building permit procedure:
  • • Not subject to notification or building permit if the structure remains mobile and temporary.
    • Exceeding size limits, fixed foundations, or permanent connections → rules for simple or other structures apply
• Other conditions: compliance with personal safety and fire regulations and any municipal permits for public spaces.

Summary: short-term rentals of up to several weeks typically do not require notification or a building permit; longer periods or permanent anchoring → classification according to the rules for temporary or permanent structures.

Short-term rental

• 100 m², height 4 m
• Seasonal market, 5 days
• Removable anchoring, temporary connections

Solution: no notification or permit required

Simple construction – notification is sufficient

• 150 m², height 4.5 m
• Seasonal storage of materials
• Removable anchoring, short-term connections
• Rental period: 12 months

Solution: Notification to the building authority

Other construction – building permit required

• 450 m², height 6 m
• Long-term storage with permanent connection to water and sewerage
• Concrete foundations, permanent connections
• Lease term: 4 years

Solution: Building permit

• Consult with the local building authority before signing the contract
• Define the purpose, rental period, and anchoring
• Prepare documentation for notification or building permit
• Consider the size, height, connections, and duration of placement
