How it is calculated
The basic formula in Law 4495/2017 depends on the area, zone price and coefficients that vary with the characteristics of the violation.
This tool does not classify a violation or confirm that it can be regularised. Category 5 is outside the current regularisation process represented here.
The range is calculated twice: area × zone price × 15% × the low or high combined coefficient. Enter coefficients confirmed by your engineer.
The filing fee is paid separately from the unified special fine. Discounts and instalment options apply to the fine, not the filing fee. The estimate excludes engineer fees, special cases and other planning charges.

Frequently asked questions
Can I rely on this as the final amount due?
No. An engineer must review the case file and confirm the category, coefficients and any exceptions.
Does it calculate category 5?
No. Category 5 is not available for a new submission in this tool.
How is the illegal building fine base calculated?
The range is calculated as area × zone price × 15% × low or high total coefficient. Enter coefficients confirmed by an engineer. The filing fee is paid separately; discounts and the 30% initial-payment threshold apply to the unified special fine. Engineer fees are not included.
