Purchasing a home under construction is one of the most common paths on the Bulgarian property market. Whether you are searching for a new family home or a long-term investment, you will inevitably encounter terms such as Act 14, Act 15, and Act 16. These designations originate from Bulgaria's statutory framework—primarily the Spatial Development Act and the relevant ordinances governing official construction records and certificates.
Behind this official terminology lie distinct construction phases, rigorous quality checks, and substantial financial commitments. To make an informed, confident decision, it is essential to understand what each document certifies, the order in which they are issued, and their legal implications for your property.
Groundwork: Before the First Storeys Rise
Before reaching these widely cited milestones, a development must navigate initial administrative and technical procedures. Everything begins with an effective building permit and approved investment designs.
Once the developer obtains these documents, an opening protocol for the construction site is drafted, establishing the building alignment and elevation levels—commonly referred to in local practice as Form 2 (Obrazets 2). At this point, heavy machinery enters the plot, safety hoarding is erected, and the foundations of the future building are staked out. For the buyer, this marks the tangible start of works from ground level, paving the way for excavation and substructure works.
Act 14: Structural Completion (Rough Construction)
Act 14 is the first major milestone buyers encounter during negotiations for off-plan or new-build properties. Its formal title is the Certificate of Acceptance of the Building Structure.
Picture the scene: the building site is a hub of activity, tower cranes hoist formwork and reinforcement steel, and across the floors, every reinforced concrete slab, column, and shear wall has been cast. The exterior brickwork is either finished or well under way, and the roof structure is in place; however, windows, glazing, external thermal insulation, and facade renders are not yet installed. A structural engineer wearing a white hard hat and carrying technical drawings inspects the levels to verify concrete strength, correct placement of rebar, and geometric accuracy.
This is precisely what Act 14 certifies: that the so-called "rough construction" (grub stroezh) has been completed in full compliance with the approved designs. Signing this document confirms that the load-bearing framework of the building has been executed safely and soundly.
From a legal standpoint, Act 14 is of fundamental importance: the building officially comes into existence as an independent legal entity. From this moment onward, individual apartments, garages, and commercial premises can be transferred separately by notary deed, and mortgage lenders can accept them as collateral. Nevertheless, the building is still far from habitable.
Act 15: The Building Is Ready for Handover
The next major milestone is Act 15, formally designated as the ascertainment certificate establishing the building's readiness for final handover.
By this stage, the property looks completely different: before you stands a finished, modern building. The facade is insulated, plastered, and painted; window frames and double glazing are installed; common areas and staircases are tiled or clad; and surrounding pavements, railings, and landscaping around the entrance are complete. Inside the apartments, utility piping and electrical cabling are installed, and screeds and wall plasters are laid.
Act 15 is the legal instrument through which the building contractor officially hands over the completed development along with all as-built documentation to the client (developer). This document is signed by all primary participants in the process:
- The client (developer);
- The chartered design engineers for each discipline (architecture, structural, plumbing, electrical, etc.);
- The main building contractor;
- The licensed construction supervisor.
By signing, they certify that the works have been executed strictly in accordance with approved designs, validated site records, and current technical standards. Any minor defects or outstanding finishing works are recorded in the act itself, along with a deadline for the contractor to rectify them. Following the signing of Act 15, the construction supervisor compiles a comprehensive final report, which is indispensable for the subsequent, concluding phase.
Act 16: Commissioning and Use Permit
In everyday conversation, buyers often refer to this concluding stage simply as "Act 16." From a technical and legal standpoint, however, the specific procedure depends on the building category under Bulgarian statutory regulations.
For developments classified as Categories 1 to 3 (such as large public developments, major infrastructure projects, or high-rise buildings), a State Acceptance Commission is convened by the Directorate for National Construction Supervision (DNSK). This commission draws up Form 16 Protocol, on the basis of which DNSK issues a formal Use Permit (Razreshenie za polzvane).
For Categories 4 and 5 (which include most standard residential buildings in urban areas), a document titled Form 16 Protocol is not actually compiled. Instead, based on the construction supervisor's final report and positive clearances from utility suppliers, the authority that issued the original building permit—usually the local municipal administration—issues a Certificate of Commissioning (Udostoverenie za vavezhdane v eksploatatsiya).
In daily practice, both conclusive instruments are colloquially referred to as "Act 16."
Picture an official panel of technical experts and municipal inspectors walking through the building with folders, blueprints, and measuring instruments. They verify fire safety systems, lift functionality, building services installations, universal accessibility compliance, and adherence to all environmental and utility conditions. Only once the authorities are satisfied that no non-conformities exist is this vital final document granted.
What Changes Once the Building Is Commissioned
The issuance of the Certificate of Commissioning (or Use Permit) fundamentally transforms the status of the property:
- Lawful Habitation: The building may only be lawfully occupied and used once this certificate is in place. Residing in it prior to this stage is prohibited by law.
- Domestic Utility Tariffs: Permanent grid connections take effect only after commissioning, allowing you to open individual accounts for electricity and water at standard residential rates. Until then, the site runs on temporary industrial electricity, which carries significantly higher tariffs.
- Address Registration: You can register your permanent or present address with the municipality at your new property.
- Handover of Keys: This is the long-awaited milestone when buyers receive the keys to their completed home, allowing them to proceed with interior design, furnishing, and moving in.
Typical Payment Schedules for Off-Plan Purchases
When buying off-plan or during construction, payment is rarely made in a single lump sum. Bulgarian law does not mandate fixed payment schedules; the terms are entirely subject to contractual agreement between developer and buyer. However, standard market practices have established payment structures tied directly to construction phases:
- Reservation Deposit: A modest fixed sum paid to take the property off the market for an agreed short period.
- First Instalment: Typically 30% to 50% of the purchase price upon signing the preliminary contract of sale.
- Second Instalment: Approximately 20% to 40% upon completion of the rough construction and signing of Act 14.
- Third Instalment: Approximately 10% to 20% upon completion of the building and signing of Act 15.
- Final Instalment: The remaining balance upon issuance of the commissioning certificate (Act 16) and execution of the final title deed before a notary.
Specific percentages may vary depending on the construction stage at which you enter the transaction, as well as the commercial terms of the respective developer.
Pre-Act 16 Risks and How to Safeguard Your Interests
Purchasing at an early stage offers the advantage of a wider selection of floors and layouts, yet it carries specific risks that should not be overlooked:
- Delays in Completion: Statutory clearance procedures and unforeseen site setbacks can postpone final commissioning by months or even years.
- Unfinished Scope of Works: The risk of a contractor leaving communal areas, exterior landscaping, or facade elements incomplete.
- Financial Distress of the Developer: In the worst-case scenario, developer insolvency can stall completion entirely.
- Utility Connection Delays: Delays in laying off-site mains for electrical power or water supply can hinder normal domestic occupation.
To keep these risks to an absolute minimum, approach your paperwork methodically. Picture a boardroom table lined with files: investment projects, architectural layouts, contracts, certificates, and official stamps.
Before signing any binding document and before transferring funds, take three indispensable steps:
- Verify the validity of the building permit and the track record of the developer's completed developments.
- Confirm who is acting as the licensed construction supervisor, ensuring the firm holds proper accreditation and an unblemished reputation.
- Have your preliminary contract reviewed by an independent real estate lawyer. Your legal counsel should carefully examine late-delivery penalties, warranty periods, commissioning commitments, and contract termination remedies.
Buying a newly built home calls for composure, patience, and meticulous attention to detail. With competent advisers by your side and a clear grasp of every construction stage, the purchase process becomes transparent and predictable.
