Home Renovation Without Violations: How to Avoid Creating New Illegal Structures

Understanding legal requirements is key to safe and compliant renovations. Interior renovations are a significant way to enhance living quality, but one misstep can lead to violations of building codes, creating what’s known as a “new illegal structure.” In recent years, local governments have become increasingly strict with the reporting and demolition of illegal constructions. Once identified as such, you could face fines and be ordered to demolish the structure, resulting in a double loss of time and money. This article will delve into common types of illegal structures and provide practical prevention guidelines to help you navigate renovations without pitfalls and complete your home improvements legally.

Common Types of New Illegal Structures

1. Enclosed Balconies

Incorporating balcony space into the interior is one of the most frequent types of illegal modifications.

• Removing exterior balcony walls.
• Adding windows or panels.
• Leveling balcony floors with the interior.
• Using the space as part of the indoor living area.

Risk Level: High – Priority for reporting and demolition.

2. Rooftop Additions

Adding structures to the rooftop terrace poses a significant risk to public safety.

• Building rooms or facilities on the rooftop.
• Constructing metal sheds or shelters.
• Exceeding limits for solar panel installations.
• Adding new staircases or elevators.

Risk Level: Very High – Subject to immediate demolition upon discovery.

3. Occupied Arcades/Ground Floor Setbacks

Enclosing or occupying the arcade or ground-floor setback area of a building obstructs public passage.

• Adding gates or fences.
• Using the space for commercial or private purposes.
• Reducing the legally mandated arcade width.

Risk Level: High – Affects public safety, prioritized for action.

4. Illegal Mezzanine Floors

Adding mezzanines within double-height spaces can exceed legal floor area ratios or height restrictions.

• Mezzanine area exceeding one-third of the legal floor area.
• Mezzanine height exceeding regulations.
• Unauthorized construction without permits.
• Compromising the building’s structural integrity.

Risk Level: Medium-High – A key focus for recent inspections.

5. Yard Encroachments

Constructing buildings or facilities in ground-floor yards or designated open spaces.

• Adding garages or storage sheds.
• Building permanent shelters.
• Exceeding fence height limits.
• Filling in legally designated green spaces.

Risk Level: Medium – Enforcement intensity varies by region.

6. Occupied Fire Compartmentation Walls

Utilizing the fire separation spaces between buildings compromises fire safety.

• Erecting advertising signs.
• Storing miscellaneous items that obstruct passage.
• Adding kitchens or bathrooms.

Risk Level: High – Affects public safety, strictly prohibited.

Expert Advice: Obtain Permits in Advance

Any project involving building structure, change of use, or additions requires prior permit application with the local building management authority. Even minor alterations that could impact building safety or violate regulations should be discussed with professionals or require a permit.
