Overview, key points and anticipated consequences
On 6 August 2025 the Parliament of Montenegro published the Law on the Legalization of Unauthorized (illegal) Buildings in the Official Gazette (Službeni list No. 91/2025). The law entered into force on 14 August 2025. The new act creates a nationwide framework for bringing unauthorised constructions into formal legal circulation and for preventing future unauthorised building.
What the law establishes – main provisions
- Transitional legalization procedure and deadlines. The law opens a formal legalization procedure that requires owners of unauthorized objects to submit requests and documentation within specified transitional periods set by the statute and implementing regulations. (Exact municipal deadlines and the detailed package of documentation are to be prescribed in implementing acts and local ordinances.)
- Prohibition on market circulation until legalized. Until a final decision is issued, buildings that do not meet permit requirements face restrictions on legal turnover – notaries are limited in processing transfers of such properties under the law and related ministry guidance. This measure effectively freezes sale transactions for a significant share of affected properties.
- Differentiated documentary and technical requirements. The law differentiates simplified procedures for small residential objects (conditional on visibility in official ortho-photo maps and other criteria) versus full technical documentation and expert reports required for larger or more complex structures.
- Financial modalities and incentives. Payment of urbanization/regularization fees may be allowed in long-term instalments (reports indicate up to 30 years in some provisions) and there are incentives for one-time payment (reported ~20% discount in some official presentations). Municipalities are to receive the majority share of collected fees (reported split 80% local / 20% state in press coverage). These figures are reported by government briefings and industry outlets.
- Land regularization and purchase options. The law foresees mechanisms for owners to acquire ownership rights over land under existing unauthorized buildings in certain cases (including staggered payment options), subject to cadastral and local-plan checks.
Quantitative scale – how many buildings and expected receipts
- Estimated number of affected objects: public and industry sources refer to roughly 100,000–120,000 unauthorized objects across Montenegro. Different official statements and media analyses give somewhat different totals; the figures are estimate to be refined by cadastral and ortho-photo verification.
- Budgetary expectations: media reports cite government estimates that the legalization programme could generate €300–400 million in one-off and phased receipts (urbanization fees, penalties, related charges). These are projection ranges communicated in ministerial and press statements; final amounts will depend on the number of successful applications, fee calculations and municipal shares.
Administrative and technical constraints
Authorities – including the Real Estate Administration and the ministry responsible for spatial planning – emphasize that the legalization process is institutionally complex: it requires coordinated cadastral checks, orthophoto verification, technical expertise (geodesy, structural/safety reports) and substantial municipal administrative capacity. Officials have underlined a phased rollout and the need to strengthen local capacities to avoid bottlenecks.
Immediate practical implications for market participants
- Owners: should prepare and submit application packages within the transitional window; simplified routes may exist for small-family homes if they meet objective criteria (e.g., visibility on the official ortho-photo). Prepare for technical reports and potential costs for documentation.
- Buyers and investors: properties without finalized legalization decisions may be effectively unsellable until resolved. Due diligence must explicitly verify legalization status and any pending administrative proceedings.
- Notaries, brokers, legal advisors: must update transaction checklists and contract clauses to address legal-status contingencies and new fee/penalty regimes. Local practice guidance from the Ministry and Notary Chamber is already circulating.
Forecasted market effects – official and expert views
- Short term: a likely drop in transactional liquidity as a sizable share of “grey” stock is temporarily frozen for sale or transfer until the legalization process advances. This may compress active listings and slow deal flow in some segments (notably coastal tourism properties and short-term rental stock).
- Medium term: if the process is implemented effectively, the market should see greater transparency and a more complete registry – a structural improvement that reduces hidden legal risk for investors and facilitates clearer valuation. The net effect on prices will depend on how many properties are legalized, municipal fee levels and subsequent investor demand.
Short conclusion
The Law on the Legalization of Unauthorized Buildings (published 6 August 2025; effective 14 August 2025) is a major regulatory step that aims to bring a large share of Montenegro’s informal building stock into the formal system while tightening controls to prevent future violations. In the near term the law introduces procedural and market friction (transaction freezes, administrative workload), while in the medium term it has the potential to increase transparency and legal certainty – contingent on resourcing, clear implementing rules and efficient municipal execution.
