Buying in a Co-ownership in Paris: The Questions Nobody Asks (But Should)

In Paris, buying an apartment means buying a unit in a co-ownership. And that co-ownership, its financial health, its past and future works, the quality of its management, the relationships between co-owners, weighs as much on the value of your property as the apartment itself. Sometimes more.

The problem is that most buyers focus all their attention on the apartment: the floor area, the floor level, the natural light, the layout. They look at photos, visit rooms, imagine their furniture. And they forget to look up at the building as a whole. A superb apartment in a poorly managed co-ownership is an investment that depreciates. A decent apartment in a healthy, well-maintained co-ownership is an asset that appreciates.

In fifteen years of property hunting in Paris and over 1,200 transactions at Home Select, I have seen buyers discover after signing a facade renovation costing 20,000 euros per unit, legal proceedings against the property manager, and unpaid charges draining the collective treasury. Every time, the information was available before the purchase. Nobody had asked the right questions.

Co-ownership charges: the number that lies

The first reflex of every buyer is to ask about the charges. The estate agent announces a figure: “250 euros per month,” and the buyer factors it into their budget. Except that this figure rarely tells the whole story.

You first need to distinguish the routine charges in the estimated budget from the actual charges incurred. The estimated budget is voted each year at the general meeting. It is an estimate, not a commitment. If actual expenses exceed the budget (and in Paris, they often do), the property manager issues supplementary payment calls at the end of the financial year. A building whose estimated budget shows 3,000 euros per year per unit can easily generate 4,500 euros in actual charges if the caretaker was on sick leave, the collective boiler required an emergency intervention, or the elevator contract was renegotiated upward.

Then, you need to distinguish routine charges from exceptional charges. Routine charges cover daily operations: caretaker, cleaning, elevator, collective heating, cold water, insurance, property manager, minor maintenance works. Exceptional charges cover major works approved at the general meeting: facade renovation, roof repair, elevator replacement, network upgrades. These exceptional charges do not appear in the annual estimated budget. They are called separately, often over several quarters.

A property hunter knows that the true cost of the co-ownership is the sum of routine charges AND exceptional charges, smoothed over five years. A building with low routine charges but a facade renovation costing 300,000 euros (meaning 15,000 to 25,000 euros per unit) every fifteen years actually costs more than a building with higher routine charges but regular maintenance.

The question to ask is not “how much are the charges?” It is: “what were the actual amounts of charges AND exceptional payment calls over the last three years?”

General meeting minutes: the building’s diary

If only one document had to be read before buying, it would be the general meeting minutes from the last three years. Not the property manager’s summary, not the estate agent’s account: the full minutes, with the voted resolutions, the vote results, and above all the recorded debates.

Here is what a property hunter looks for.

Works approved but not yet carried out. A facade renovation approved two years ago but not yet started means that payment calls are coming. The amount is voted, the breakdown by shares is known: it is a certain cost that the buyer will have to bear. It is also a powerful negotiation lever.

Works proposed but rejected. If the property manager proposed a facade renovation, a roof repair or an elevator replacement and the general meeting rejected it, the works are not cancelled: they are postponed. And they become more urgent and more expensive every year. A building that systematically postpones major works is a building that is deteriorating.

Ongoing legal proceedings. Co-ownership against a co-owner for unpaid charges. Co-ownership against the property manager for poor management. Co-owner against the co-ownership for nuisance or defective works. These proceedings generate significant legal fees (5,000 to 20,000 euros per year is not uncommon) and create a climate of tension in the building.

Unpaid charges. The total amount of unpaid charges is mentioned in the property manager’s report presented at the general meeting. High unpaid charges (more than 15% of the annual budget) are a serious warning sign: they mean that some co-owners cannot or will not pay, which weakens the collective treasury and can lead to difficulties in funding routine maintenance.

Tensions between co-owners. The minutes are sometimes eloquent about the atmosphere in the building. Systematically close votes, motions of no confidence against the property manager or the council, recurring complaints about noise, common areas or unauthorized works: all of this gives a faithful picture of daily life in the building.

At Home Select, our 16 property hunters request and read the general meeting minutes before recommending a property to their clients. It is a filter we apply upstream: a magnificent apartment in a dysfunctional co-ownership will simply not be recommended, unless the price already fully reflects the risk.

The works fund: the reserve that should exist

Since the Alur law of 2014, every co-ownership must establish a works fund supported by an annual contribution of at least 5% of the estimated budget. This fund is used to finance works decided by the general meeting, without having to resort to exceptional payment calls that put some co-owners in difficulty.

In theory, it is an excellent measure. In practice, many Parisian co-ownerships apply the legal minimum (5%) and the works fund remains symbolic compared to the amounts of major works. A 20-unit Haussmann-style building with an estimated budget of 80,000 euros per year contributes 4,000 euros to the works fund. After five years, the fund reaches 20,000 euros. The facade renovation for this building will cost 250,000 to 400,000 euros. The works fund covers barely 5 to 8% of the need.

What a property hunter checks: the existing works fund balance and the contribution rate. A well-funded reserve (contribution above the legal minimum) is a sign of good management and forward planning. An empty or nearly empty fund in a building that has not been renovated in twenty years is a clear warning sign.

Important legal point: the works fund is attached to the unit, not to the co-owner. When you buy, you acquire the works fund share of the unit you are purchasing, but the seller cannot claim a refund. This is an advantage for the buyer: the money is already provisioned.

The property manager: the building manager you did not choose

The property manager is the building’s administrator. They collect charges, pay contractors, organize general meetings, manage claims and works. The quality of the property manager has a direct impact on daily life in the building and on the value of your property.

In Paris, professional property manager fees range from 150 to 350 euros per unit per year for routine management, plus fees for specific services (works supervision, litigation, ownership transfers). Large firms manage hundreds of buildings and do not always have time to attend to each one with the same care. Small independent firms often provide better follow-up but are harder to reach.

What the property hunter looks for: consistency between the manager’s fees and the visible quality of management. A building whose common areas are clean, whose accounts are clear and presented on time, whose approved works are completed on schedule: that is a well-managed building. A building whose entrance is shabby, whose accounts arrive late at the general meeting, whose co-owners complain about the manager at every meeting: that is a warning sign.

The volunteer property manager (a co-owner who handles management for free or for a modest compensation) exists in some small Parisian co-ownerships. It is economical but risky: managing a co-ownership is technical (accounting, law, insurance, works contracts) and a volunteer, even with the best intentions, can make costly mistakes. Our property hunters are particularly vigilant in co-ownerships with volunteer managers.

Shares: voting power and the distribution key

Each co-ownership unit is defined by a number of shares that determine two things: your portion of general charges and your voting weight at general meetings.

Shares are set in the co-ownership regulations, a document established when the co-ownership was created and rarely modified since. In Haussmann-style buildings, the distribution reflects 19th-century conventions: the “noble” floors (2nd and 3rd) often have more shares than the upper floors, even though converted attic duplexes are now worth much more per square meter.

For the buyer, shares have three concrete consequences. Your charges are proportional to your shares. Your contribution to approved works is as well. And your voice at general meetings carries proportional weight. A unit with many shares pays more in charges but has more influence over collective decisions.

A classic trap our apartment hunters flag: the service rooms on the top floor, sold separately from the main unit. These small units generally have few shares (and therefore low charges), but they carry no weight at general meetings. If the building votes for a facade renovation, the service room owner pays little but has no say in decisions affecting the building.

Conversely, a majority co-owner (holding more than 50% of shares) can block all decisions requiring an absolute majority. This is a situation we systematically avoid: buying in a building where a single owner controls the votes means giving up any ability to influence building management.

The co-ownership regulations: the rules of the game

The co-ownership regulations define the rules of collective living: the building’s purpose (residential, mixed-use, commercial), distribution of charges, use of common and private areas, conditions for works, whether pets are allowed, prohibited activities.

In Paris, co-ownership regulations often date from when the building was first converted to co-ownership, sometimes in the 1960s or 1970s. Some clauses have become obsolete or unenforceable, but the regulations remain the reference document in case of dispute.

What a property hunter checks in the regulations: the purpose of the units (a residential unit cannot be converted to commercial use without amending the regulations, voted at a general meeting). Exclusive use clauses (a terrace with “exclusive use” is not a property right: it can theoretically be reassigned). Restrictions on works (some regulations prohibit floating floors, require carpet for sound insulation, or limit facade modifications). The distribution keys for special charges (elevator, collective heating) which can hold surprises.

A concrete example: a client wanted to buy a ground floor apartment with a private courtyard in the 11th arrondissement. The listing mentioned “30 sqm courtyard.” Reading the co-ownership regulations revealed that the courtyard was actually a common area with exclusive use, with a prohibition on building a conservatory or planting trees taller than two meters. The dream of a glass extension evaporated, but it was better to know before than after signing.

Future works: the invisible cost

The question every buyer should ask, and almost nobody does, is: “What works are foreseeable in the next five to ten years?”

Parisian buildings follow relatively predictable maintenance cycles. Facade renovation is mandatory every ten years in Paris (though many buildings exceed this deadline). Roof repair occurs every twenty to thirty years. Elevator replacement every twenty-five to thirty-five years. Collective plumbing repair every forty to fifty years. Collective boiler replacement every twenty years.

By cross-referencing the dates of the last major works (readable in the general meeting minutes) with these average cycles, a property hunter estimates the likely schedule of upcoming works and their approximate cost. A facade renovation in Paris costs between 50 and 120 euros per sqm of facade, meaning 200,000 to 500,000 euros for a medium-sized Haussmann-style building. Divided by the number of units and shares, that is 10,000 to 25,000 euros per apartment.

Zinc roof repair (the standard material for Parisian roofs) costs between 150 and 250 euros per sqm, meaning 60,000 to 150,000 euros for a standard building. Elevator replacement: 50,000 to 80,000 euros. Electrical riser upgrade: 30,000 to 60,000 euros per riser.

These figures are not scare tactics: they are realities of co-ownership life in Paris. A well-maintained building absorbs these costs progressively. A building that has postponed all works for twenty years faces a wall of investments that can exceed 50,000 euros per unit within a few years.

Our property hunters systematically incorporate this works projection into the price assessment. An apartment listed 50,000 euros below market in a building that has not been renovated in fifteen years and whose roof is thirty years old is not a good deal: it is a price that anticipates future works.

Co-ownerships in difficulty: the warning signs

Some Parisian co-ownerships are in financial difficulty, or even subject to court-appointed administration. Fortunately this is rare in the central and western arrondissements, but it exists in some buildings in the 18th, 19th and 20th, and in some 1960s-70s co-ownerships in the inner suburbs.

The warning signs our apartment hunters look for: an unpaid charge rate exceeding 25% of the annual budget, safety works not carried out despite formal notices, a court-appointed administrator, unanswered payment calls, a building listed in the register of co-ownerships in difficulty maintained by the national housing agency.

Buying in a co-ownership in difficulty means exposing yourself to unpredictable payment calls, court-ordered works, and very low liquidity in case of resale. This is a territory we systematically advise our clients against, unless they have a very experienced investor profile with a long-term horizon.

What the property hunter checks and the estate agent does not mention

The estate agent sells an apartment. The apartment hunter buys a unit in a co-ownership. The difference in perspective is fundamental.

The agent will talk about the natural light, the ceiling height, the herringbone parquet. The property hunter, in addition to all of that, will check the condition of common areas (stairwell, entrance, bin storage, cellar), request general meeting minutes and charge statements, review the statement of accounts, check the asbestos technical assessment of common areas, identify future works and calculate their impact on the budget.

This analysis work takes time: two to three hours per property, before the viewing or just after. It is an investment that the estate agent, paid by the seller, has no reason to make for the buyer. This is exactly why a property hunter exists.

At Home Select, this co-ownership analysis is systematic. Over our 1,200 transactions supported since 2011, it has led our property hunters to rule out about one in five properties that seemed attractive on the surface but presented excessive co-ownership risks. And for the properties retained, it fueled an average negotiation of 6% on the listed price.

The questions to ask before signing

To summarize, here is the checklist of questions that an informed buyer, or their apartment hunter, should ask before committing to an apartment in a co-ownership in Paris.

On charges: what has been the actual amount of routine charges over the last three years? Have there been any exceptional payment calls? For what amount?

On works: what works have been approved but not yet carried out? When was the last facade renovation? And the last roof repair? What is the condition of the elevator, the collective boiler, the plumbing?

On management: who is the property manager? For how long? Are the accounts approved without reservation? What is the amount of unpaid charges? Is the works fund funded above the legal minimum?

On legal matters: are there any ongoing proceedings involving the co-ownership? Have the co-ownership regulations been brought into compliance with the Alur and Elan laws? Are there any easements or specific restrictions?

On asbestos: has the asbestos technical assessment of common areas been carried out? What asbestos-containing materials have been identified and what is their condition?

Half of these questions do not have an immediate answer: you need to request the documents, read them, cross-reference them. It is tedious work that few buyers do on their own. It is also one of the reasons why buyers who use an apartment hunter make better-informed decisions, negotiate more effectively, and avoid the unpleasant surprises that turn a property dream into a financial nightmare.
