Review of Fitness for Occupancy

What is a Review of Fitness for Occupancy and how does it differ from the old kolaudácia?

A Review of Fitness for Occupancy (preskúmanie spôsobilosti stavby na užívanie) is the final verification process confirming that a completed building conforms to approved plans, meets all applicable technical and safety regulations, and is legally permitted for occupancy and use. This is the successor to the old occupancy approval (kolaudácia) under Slovakia's new Building Act 25/2025, which took effect on April 1, 2025. While the core function remains unchanged—verifying that constructed reality matches approved intent—the new act introduces updated terminology, clearer procedural parameters, and strengthened documentation requirements. The fitness review process specifically examines whether the completed building's systems, materials, performance, and safety features meet the specifications detailed in the approved project documentation and satisfy all legal requirements. For residential projects, this includes verification that thermal performance, airtightness, ventilation, electrical systems, plumbing, gas connections, and structural integrity all function as designed. The review results in an occupancy certificate (osvedčenie o splnení účelu stavby, or certificate of fulfillment of building purpose) permitting legal use.

When is a Review of Fitness for Occupancy required, and what buildings are exempt?

Any building project that required a Building Intent Decision must undergo fitness review before occupancy. This includes new residential houses, apartment buildings, commercial buildings, industrial structures, and substantial renovations or extensions of existing buildings. The fitness review is mandatory before a building can legally be used for its intended purpose. Minor structures (malé stavby) that qualified for simplified notification rather than full Building Intent proceedings may be exempt from fitness review requirements, though this depends on local regulations and specific project characteristics. Reserved structures (those serving public interest or strategic functions) may follow modified procedures. The safest approach is to consult your municipal building authority early; they will confirm whether your specific project requires fitness review. For residential projects targeting passive-house standards or qualifying for Slovakia's Obnov Dom renovation subsidies, fitness review is universally required and includes performance testing to verify energy targets have been achieved.

What are the key phases and timeline of the fitness review process?

The fitness review process unfolds in distinct phases, each with statutory deadlines. After construction is substantially complete and all required documentation is assembled, the building owner or developer submits the application (najčastejšie prostredníctvom Portálu Stavby, the Building Portal) to the municipal building authority. The authority must notify the applicant of the inspection appointment within 7 days. The actual inspection site visit occurs within 30 days of that notification; the building authority inspector (stavebný úrad) reviews documentation, conducts a physical inspection of the building, observes test procedures (such as blower-door testing for airtightness, thermal imaging for insulation gaps, or system commissioning), and verifies that actual construction matches approved drawings and meets safety standards. Following the inspection, the authority has 15 days to issue a decision: either an occupancy certificate (if all conditions are met) or a decision requiring corrections or additional inspections. If corrections are mandated, the owner must address them and request re-inspection, extending the timeline by 2–4 weeks. Total elapsed time from submission to final certificate is typically 4–6 weeks for straightforward projects; complex buildings or those with documentation gaps may require 2–3 months or more.

Phase	Activity	Typical Duration	Responsibility

2. Submission	Submit application and documentation via Building Portal or in-person	1 day	Building owner or developer
3. Scheduling	Authority notifies applicant of inspection date	Within 7 days of submission	Building authority
4. Inspection	Physical site inspection, testing, documentation review	Within 30 days of scheduling notification	Building authority inspector
5. Decision	Issue occupancy certificate or correction notice	Within 15 days of inspection	Building authority
6. Registration	Register building in cadastre, assign property number	2–4 weeks after certificate issuance	Cadastral office, municipality

What documentation and supporting studies must be submitted for fitness review?

The fitness review application must include comprehensive documentation demonstrating that the completed building meets approved specifications. Essential documents fall into several categories. First, authorization and approval documentation: the original Building Intent Decision, project modification decisions (if applicable), and proof that all decision conditions have been satisfied. Second, design and construction records: the approved architectural, structural, and technical project documentation; the construction supervision records and construction log (stavebný denník) documenting all site work, inspections, and any deviations from approved plans; and photographs or video documenting key construction phases. Third, system inspections and testing: final inspection reports for electrical installations (including lightning protection), gas systems, water supply and drainage, heating systems, and chimney inspections—these reports must be signed by qualified inspectors and must confirm compliance with Slovak technical standards (STN). Fourth, energy performance documentation: the energy performance certificate, and if the building is a passive house or target of the Obnov Dom subsidy program, commissioning protocols demonstrating that performance targets (airtightness, thermal integrity, ventilation effectiveness) have been verified through testing (such as blower-door testing per EN 13829, thermography, or ductwork pressure testing). Fifth, geometric and cadastral documentation: an updated geometric survey (geometrický plán) confirming the building's footprint, area, and location; proof of land ownership or usage rights; and confirmation of utility connections (water, sewage, electricity, gas, telecommunications). Sixth, compliance certifications: declarations from the builder/contractor confirming adherence to approved plans and applicable regulations; manufacturer certificates for materials and systems; and proof that all administrative fees and utilities deposits have been paid. Any missing documentation will delay the inspection or result in a correction notice; most fitness review rejections stem from incomplete documentation rather than construction defects.

What is examined during the fitness review inspection, and what are the inspection criteria?

The fitness review inspection is a multifaceted examination conducted by qualified building authority inspectors. The inspector verifies structural integrity: foundation stability, load-bearing wall and column alignment, roof structure condition, and absence of cracks or defects that would compromise safety. Interior and exterior envelope condition is assessed: window and door seals, insulation continuity (especially at thermal bridges), roof waterproofing, exterior finishes, and protection against weather and moisture ingress. Building systems are tested: electrical installation continuity and safety, lighting functionality, heating system operation and thermostatic controls, water supply pressure and sanitary fixtures, gas appliance operation (if applicable), drainage system function, and chimney draft and ventilation. For residential buildings, comfort and performance criteria are verified: achieved airtightness (measured via blower-door test per EN 13829, targeting n50 <6 air changes per hour for passive houses or standards required by the approved design), surface temperatures in corners and at thermal bridges (verified via thermography, confirming the temperature factor fRsi meets STN 73 0540 mold-risk criteria), ventilation system commissioning (for mechanical systems), and energy performance test reports. Safety systems are inspected: fire safety doors and escape routes, smoke detectors (if required), emergency lighting, and handrails or protective barriers. Documentation alignment is verified: the inspector confirms that what was constructed matches the approved project documentation, construction log entries match site reality, and all deviations from approved plans have been properly documented and justified. The inspection also includes a visual and functional walk-through to confirm the building is clean, finished, and habitable. For complex or high-performance buildings (passive houses, energy-positive buildings), the inspection may include specialist subcontractors (HVAC commissioning technicians, energy auditors, airtightness testers) to verify performance claims.

How does fitness review connect to energy performance and passive-house standards?

Energy performance verification is a central component of the fitness review for all residential buildings under Slovakia's Building Act 25/2025. New buildings must achieve nearly zero-energy building (NZEB) status, a standard aligned with European Union energy directives and passive-house principles. The fitness review includes submission and verification of the energy performance certificate (certifikát energetickej náročnosti budovy), which documents the building's calculated or measured annual energy demand (typically expressed in kWh/m²/year), CO₂ emissions, and renewable energy contribution. For buildings pursuing passive-house certification—increasingly common in Slovakia's residential sector—the fitness review is more rigorous and includes commissioning protocols demonstrating achievement of passive-house performance targets. These targets include airtightness (n50 <6 air changes per hour, verified via blower-door test per EN 13829), heating demand (<15 kWh/m²/year or 6 kJ/m²/year derived from the standardized passive house methodology), and optimal thermal comfort (achieved through superinsulation, thermal bridge elimination, mechanical ventilation, and sometimes solar orientation and thermal mass). Passive-house projects must submit detailed commissioning documentation showing that airtightness, thermal bridging, ventilation airflow, system controls, and energy demand have all been tested and verified to specification. Slovakia's Obnov Dom (Rebuild House) subsidy program for residential renovation projects similarly requires energy performance verification as part of fitness review; buildings must achieve 30% energy demand reduction or reach passive-house standards to qualify for rebates. The fitness review thus serves as the final verification gate ensuring that design intent and specifications have been faithfully executed and that the building will perform as designed during operation.

What happens if a building fails the fitness review inspection or if defects are identified?

If the building authority inspector identifies defects, non-conformities, or missing documentation during the fitness review, the building authority does not issue an occupancy certificate. Instead, the authority issues a correction notice (rozhodnutie o potrebe úpravy, or similar decision) specifying what must be remedied. Common reasons for rejection include: incomplete documentation (missing inspection reports, geometric survey, energy certificate, or commissioning records); discrepancies between approved plans and actual construction (unauthorized modifications, size changes, material substitutions); defective systems (electrical continuity failure, heating system malfunction, water leaks, ventilation system not installed); performance failures (airtightness test results worse than specified, surface temperatures in thermal bridges below safety thresholds, energy performance exceeding design targets); or safety violations (fire safety doors non-functional, escape routes blocked, structural cracks, exposed electrical conductors). Upon receiving the correction notice, the building owner must address the identified defects. For documentation issues, this may simply mean gathering missing certificates or commissioning the missing reports (a contractor or energy auditor can often supply these retroactively). For physical defects, the contractor must return to site, correct the problem (replacing insulation, re-sealing a duct, reinstalling a heating control, etc.), and document the correction. Once the defects are addressed, the owner requests a re-inspection appointment; the building authority typically charges a re-inspection fee (approximately €60 per re-inspection under 2025 fee schedules) and must schedule a follow-up inspection within 30 days. For minor defects, re-inspection may occur within days; for major structural or system issues, several weeks may pass. Projects with extensive defects may require multiple re-inspections before approval. In rare cases of serious defects (structural instability, fire safety violations, system failures that pose safety risks), the building authority may refuse final approval, effectively prohibiting occupancy until the defects are resolved. This underscores the importance of ongoing quality control during construction and advance coordination with the building authority on inspection requirements.

How does the fitness review process work for buildings constructed during the transition period?

Slovakia's Building Act 25/2025 introduced both a regular fitness review pathway for new projects and an extraordinary legalization mechanism (retroactive fitness review, or § 140d of the new act) for buildings constructed without proper authorization between January 1, 1990 and March 31, 2025. For buildings in this transition window, property owners can apply for a retroactive Review of Fitness for Occupancy—essentially a legalization proceeding—if the building meets specific conditions: it must be completed and in use, pose no safety or fire risk, comply with territorial planning regulations (assessed favorably to the owner's interest), and the owner must hold proper land rights. This extraordinary procedure allows owners of unauthorized buildings to gain legal occupancy status by undergoing an intensive examination process, including technical inspections, cadastral verification, and potentially higher fees (triple the standard building permit fee). However, this retroactive legalization pathway is available only until March 31, 2029; after that deadline, it will no longer be possible to legalize structures built without authorization. For projects that received authorization under the old 1976 Building Act but have not yet completed fitness review (kolaudácia) as of April 1, 2025, they may continue under old procedures or elect to transition to the new fitness review process; clarification on this transition is best obtained from the local building authority.

What is the relationship between the Building Intent Decision and the Review of Fitness for Occupancy?

The Building Intent Decision and the Review of Fitness for Occupancy are two distinct milestones in a building project's lifecycle, separated by the construction phase. The Building Intent Decision is issued before or early in construction; it is a design authorization and construction license, specifying what may be built and on what conditions. It sets parameters: site location, approved use, maximum floor area and height, design principles, and technical standards the building must meet. The Review of Fitness for Occupancy occurs after construction is substantially complete; it is a verification that the constructed reality matches the authorized intent and that all systems function safely and as specified. Put simply: the Intent Decision says "you are authorized to build this design with these specifications"; the Fitness Review says "you have built it, and the result matches the authorization and meets all legal requirements." Both are essential. A project cannot proceed without the Intent Decision (authorization); it cannot legally be occupied without passing the Fitness Review (verification). Between these two milestones lies construction supervision, ongoing quality assurance, and regular inspections to ensure the work remains compliant. Understanding this sequential relationship is crucial for project planning and risk management.
