Renovation Permits in Serbia: What You Can Do Without One, What You Can't

No permit needed

• Interior cosmetic work: painting, flooring, new bathroom fixtures in the existing layout.
• Replacing a window within the same opening and frame dimension (check your building bylaws, facade unity often matters).
• Installing cabinets, built-in furniture, non-load-bearing partition walls that don't affect utilities.

Simple notification (prijava radova)

• Moving non-load-bearing walls, re-routing electrical circuits, small plumbing changes.
• Replacing boilers or AC outdoor units (check your condo rules and facade policies).

Construction permit required

• Anything touching load-bearing elements, walls, columns, balcony plates.
• Gas line modifications.
• Expanding the footprint: enclosing a balcony, combining two apartments into one, converting attic space.
• Changing the official use of the space (stan → poslovni prostor, or vice versa).

The enforcement reality

Inspections usually trigger after a neighbor complaint. By then, the fine is the smaller problem, the bigger one is the order to restore original condition, which can require tearing out months of work at your expense. Worse still, the apartment becomes harder to sell or mortgage because the cadastre no longer matches the physical state.

Legalization

Unpermitted changes can sometimes be legalized retroactively if they don't affect structural safety. The process costs money and time but is far cheaper than tearing out and redoing.
