Does a Zoning Plan Amendment Always Generate a Value Increase Contribution?
A value increase contribution does not apply to every market-price increase; the amendment's scope, date and particular conditions are decisive.

No. An increase in market price differs from a value increase contribution arising from a zoning plan amendment. First examine whether the amendment falls within current rules. The owners' request, planning decision, property's status, application and assessment dates matter. Exclusions and transitional provisions must be assessed separately.

The implementing regulation dated 22 November 2025 provides for 90% of the determined value increase in covered transactions to be transferred to the public. This does not mean 90% of the property's entire sale price. Valuation compares conditions before and after the amendment. The value of existing buildings and accessories differs from planning-generated land appreciation. The applicable calculation must be established through documents and decisions.

The obligation may affect the investment's net outcome and timetable. Before payment is complete, the regulation restricts sale, transfer, gift and certain planning or permit procedures. Lump-sum or instalment payment terms, dates and exceptions are examined in their file. Calculating only expected planning value while excluding the public contribution and valuation expenses is therefore inappropriate.

We examine the amendment proposal, approval and display documents, valuation reports, assessment and payment records together. Before a transaction, we identify possible financial and legal conditions; for an ongoing file, the rules governing the existing procedure. No promise is made that an amendment will occur, a particular gain will result or the contribution will necessarily be removed.
