Uninhabitable apartment cleaning in Paris 9th
A badly deteriorated flat in Paris 9th cannot always be understood from what is visible inside its rooms. A narrow light well, shared ventilation ducts and a drainage column may connect several neighbouring lots. Dampness, a recurring odour or an unexplained flow can therefore come from outside the flat. We clean the private scope and identify anything that belongs to the shared building structure.
The wording used to describe a flat does not establish its official status or explain the occupant’s situation. We describe waste, surfaces and material operations without making a personal diagnosis. Floors, walls, fittings and visible deposits are assessed separately from common ducts and columns. Work inside the flat cannot resolve a cause carried through a shared route, so exclusions and limits are stated before the cleaning begins.

A narrow light well and a shared drainage column
In Paris 9th, many flats face a narrow light well where windows, ventilation grilles and drainage routes sit close to one another. A room may show dampness, an odour or an unexplained flow even though the source lies outside the private surfaces. A shared drainage column can pass through several floors, while ventilation ducts connect adjoining lots around the same confined courtyard. What appears on an interior wall, near a sink or around a skirting board therefore cannot automatically be attributed to the flat itself. We distinguish the floors, walls, fittings, waste and deposits that belong to the private lot from the grilles, ducts, columns and other structures that form part of the building. A sink or trap inside the flat may be examined as an interior fitting, but the common route beyond it is not included in the same operation. The narrow light well can make observation from outside difficult and does not turn a shared structure into private property. We describe what can be seen and reached inside the flat, then identify what should be reported to the syndic. A recurring odour may remain connected with a common column even after accessible surfaces have been cleaned. The written scope must therefore name the rooms, surfaces and fittings included, rather than treating the entire address as one uninterrupted area.
The name of the service says nothing about the official status of the flat. We describe waste, surfaces and material operations without diagnosing the occupant, assigning an administrative category or interpreting the personal circumstances behind the condition. Visible dampness, deposits and damage are recorded for practical cleaning purposes, but they do not prove where an underlying cause begins or ends. We never open a shared ventilation duct or drainage column without the syndic’s agreement. Access to common areas belongs to the building’s responsible parties and cannot be inferred from an occupant’s access to the flat. Cleaning inside the private lot may remove waste or deposits from accessible surfaces, but it does not resolve what comes through a shared column. We therefore state what is cleaned, what is reported and what remains outside the scope. The work does not promise habitability or the disappearance of an odour, especially where a common route continues to carry air, water or other effects between floors. A clear separation of private and common elements allows the practical cleaning to be described without presenting it as a repair of the building’s shared systems.
A method for assessing and cleaning the private scope
Describe the flat
We record the rooms, floors, fittings and accessible surfaces where waste, deposits, dampness or other conditions are visible.
Identify the observations
We note odours, moisture, flows and material traces without assuming that their source lies within the private lot.
Name each fitting
Sinks, traps, extraction grilles, skirting boards and coverings are described separately so their limits can be understood.
Separate common systems
We distinguish the private surface from any ventilation duct, drainage column, grille or structure shared with other lots.
Define the operations
Waste removal and cleaning are limited to the surfaces and material tasks that have been expressly included.
Record the exclusions
The scope states what belongs to the syndic, what remains inaccessible and which causes cannot be resolved by interior cleaning.
The criteria examined for a deteriorated flat
- Condition of interior surfaces
- Waste and deposits present
- Dampness observed inside
- Odours or unexplained flows
- Sink or trap identified
- Shared duct nearby
- Common drainage column
- Accessible areas and exclusions
The assessment covers the interior surfaces and fittings that belong to the flat and can be reached safely within the agreed scope. It records waste, deposits, dampness, odours and flows without assuming their origin. Sinks, traps, extraction grilles, coverings and skirting boards are named separately. Shared ventilation ducts, drainage columns, light wells and other common areas remain outside the private scope without the syndic’s approval. The description states what is cleaned, what is reported and what remains excluded, without promising habitability or the disappearance of an odour.

Frequently asked questions about deteriorated flat cleaning
Must dampness inside the flat come from inside the flat?
No. In a dense Paris 9th building, a shared drainage column or ventilation duct may carry moisture or an associated effect between floors. We clean the private surface and report any possible common cause separately.
Do you open a shared drainage column?
No. A common column belongs to the building structure and requires the syndic’s approval for access. We can describe what is visible from inside the flat, but we do not treat the shared route as private.
Is a sink always included in the cleaning scope?
No. The sink is identified according to its position, condition and connection. Its accessible private surface may be included, while the shared pipe beyond it remains outside the scope unless separately authorised.
Does the word “uninhabitable” establish an official status?
No. The service describes a material condition involving waste, surfaces and practical operations. It does not diagnose the occupant, assign an administrative status or replace any official assessment of the premises.
Can interior cleaning stop an odour coming through a duct?
No. Cleaning may address the accessible surfaces inside the flat, but an odour carried through a shared duct or drainage column requires a separate examination by the responsible building party.
Are common areas included when a mark is visible there?
No. A light well, shared grille, landing, duct or drainage column remains outside the private lot. A mark may be reported, but it does not become part of the interior cleaning scope.
Does this cleaning promise habitability or the disappearance of an odour?
No. The service describes the material operations carried out on accessible private surfaces. It does not promise habitability or the disappearance of an odour linked to a common system or another cause.
