An apartment always involves two levels of risk: the building as a whole and your specific unit (apartment / PD / garage).
We start with an analysis and document in writing where the problem actually lies — at the apartment level, the building level, or in the documentation — and which actions are realistically possible.
Written conclusion: possible / not possible / under which conditions
Risk map: separately for the building and for your apartment (PD)
Action plan: what should be done now and what makes sense to do later — without unnecessary procedures
In apartment buildings, it is essential to distinguish whether the issue originates at the building level or within your specific unit (PD). We identify risks and define a clear sequence of actions — without unnecessary procedures.
Block 1: Building-level issues
Missing or incomplete construction and design documentation
Additional floors or significant structural modifications
Absence of an occupancy permit (use permit)
Building-wide inconsistencies
(number of floors, footprint, common areas, legal status)
Zoning and planning restrictions affecting available scenarios
Block 2: Unit-specific issues (PD)
Layout changes / merging / subdivision not reflected in documents
Mismatch between actual area and registered apartment / PD data
Unclear ownership of certain spaces (terraces, storage rooms, corridor or stairway sections)
Different legal status of parts of the unit (residential / non-residential / auxiliary)
Risks that arise during a transaction (bank requirements, notary review, buyer due diligence)
Result — a written document: conclusions, risks, and an action plan tailored to your specific case
Legal status and documentation
We review which documents are available or missing and identify inconsistencies. We flag restrictions, stop-factors, and risks that affect the overall scenario.
Building vs. apartment (where the issue originates)
We separate risks at the level of:
the building as a whole, and
your apartment (PD).
We clearly distinguish what relates to the building (e.g. construction documentation, occupancy permit) and what relates to the individual apartment.
Apartment and PD status: composition of the unit
We clarify what legally belongs to the apartment:
area and layout,
composition of spaces (terrace, storage, etc.),
potential “grey zones” between the apartment and common areas.
Facts vs. documents: alterations and discrepancies
We compare the actual layout and area with the documentation. We identify alterations and discrepancies that impact registration or a transaction.
Scenarios: what is realistically possible and under which conditions
We provide a written conclusion in the format: possible / not possible / possible under conditions. We specify whether legalization of the apartment itself is required, or whether the issue is resolved at the building or documentation level.
What to request / obtain and what to verify (checklist)
We prepare a clear checklist:
which documents are required,
where to obtain them, and
for what purpose.
We also indicate what must be verified on site.
Not all apartments in problematic buildings require legalization. The analysis helps select the correct scenario and avoid unnecessary actions.
Apartment workflow stages
Step 1: Input data → task definition
We define the goal: legalization / transaction / risk assessment. We collect the minimum: address / KO / LN / (if available) PD.
Step 2: Risk separation → building vs. apartment
We identify where the issue originates: — the building (documentation, status, occupancy permit, additions) — the apartment (PD).
Step 3: Data and document analysis → risk map
We compare facts vs. documentation, apartment status, and unit composition. The result is a clear map of critical vs. acceptable issues.
Step 4: Written conclusion → “possible / not possible / under which conditions”
The result is provided in writing: conclusion + conditions + step-by-step plan. We clearly state whether the apartment itself requires legalization or if the issue is resolved at the building or documentation level.
If confirmation is required (alterations, “grey zones”, disputed areas), we perform measurements and prepare materials to the required extent, without unnecessary procedures.
Step 6: Further actions according to the selected scenario
We prepare the full set and support the selected path: legalization, corrective steps, preparation for transaction / registration.
