Glossary of Paris property terms

The building and the apartment

Étage noble ay-TAHZH nobl

The étage noble ("noble floor") is the most prestigious floor of a Haussmann-era Paris building: usually the second floor in French numbering, which is the third floor in American numbering. It has the highest ceilings, the tallest windows, the richest mouldings and a continuous balcony across the façade.

It was designed for the wealthiest family in the building at a time when there were no lifts: high enough to be away from the street, low enough to climb easily. There is only one per building, which is why apartments on the étage noble carry a lasting premium. The Italian equivalent is the piano nobile.

Haussmannien (Haussmann building)

A Haussmann building is a cut-stone apartment block built during or after the transformation of Paris led by Baron Haussmann between 1853 and 1870. The style continued into the early 1900s. Typical features are a stone façade, five or six storeys, wrought-iron balconies on the second and fifth floors, a slate or zinc mansard roof, and inside: herringbone parquet, marble fireplaces and ceiling mouldings.

Enfilade

An enfilade is a suite of reception rooms aligned along the façade, with their doors on a single axis so that you can see from the first room to the last. In a Paris apartment it usually means the salon, the dining room and sometimes a library opening one into the next. It is what gives a classic apartment its sense of scale and light.

Hôtel particulier

A hôtel particulier is a private townhouse, not a hotel: a freestanding or semi-detached mansion built for one family, typically set between a front courtyard and a rear garden (entre cour et jardin). Most date from the 17th to the 19th century and are concentrated in the Marais, the Faubourg Saint-Germain (7th arrondissement) and parts of the 8th and 16th. Very few come to market each year.

Pied-à-terre

A pied-à-terre is a secondary home in the city, used for part of the year rather than as a main residence. In Paris it is typically a one- or two-bedroom apartment in a central arrondissement. Legally it is a résidence secondaire, which affects local taxes and the rules on renting it out short-term.

Parquet, moulures, cheminée

The shorthand used in listings for the three period features buyers expect in a classic Paris apartment: solid oak parquet (often laid in herringbone, point de Hongrie, or chevron), plaster ceiling mouldings and cornices, and marble fireplaces. When all three are original and intact, agents say the apartment has kept its cachet.

Chambre de service

A chambre de service is a former maid's room on the top floor of a period building, usually under the roof and reached by a service staircase. They are often sold with a large apartment in the same building, and are used as a studio, an office or storage. Check the floor area: below 9 m², a room cannot legally be rented as a dwelling.

Hauteur sous plafond

Ceiling height. In Haussmann buildings it varies by floor: generally highest on the étage noble and lower on upper floors. It is one of the first figures to ask for, because it changes the feel of a room more than floor area does and it cannot be altered.

The purchase

Notaire

A notaire is a public legal officer appointed by the French state. Every property sale in France must be signed before a notaire, who verifies title, collects the transfer taxes for the state, holds the funds and registers the deed. The notaire is neutral, but buyer and seller may each appoint their own at no extra cost: the two share the same regulated fee.

Compromis de vente

The compromis de vente is the preliminary sale contract that binds both buyer and seller once an offer is accepted. It sets the price, the completion date and the conditions under which the sale can fall through (conditions suspensives), and is usually accompanied by a deposit of around 5 to 10 percent held by the notaire. Completion normally follows about three months later.

Promesse de vente

A promesse unilatérale de vente is the alternative to the compromis, common in Paris. The seller commits to sell at a set price for a fixed period; the buyer has an option to buy and pays a holding deposit (indemnité d'immobilisation). In practice it leads to the same result as a compromis.

Délai de rétractation

The cooling-off period. After signing the preliminary contract for a home, a private buyer has 10 days to withdraw without giving a reason and without penalty, and any deposit is refunded. The seller has no equivalent right.

Condition suspensive

A condition suspensive is a condition written into the preliminary contract that, if not met, cancels the sale and returns the buyer's deposit. The most common one is obtaining a mortgage. A cash buyer who waives the financing condition makes a stronger offer, but gives up that protection.

Acte authentique (acte de vente)

The final deed of sale, signed before the notaire. Ownership, the balance of the price and the keys all change hands on that day. A buyer who cannot travel can sign by power of attorney (procuration).

Frais de notaire

The closing costs paid by the buyer on top of the price. Despite the name, most of the amount is transfer tax collected for the state and local authorities; the notaire's own fee is a small, regulated part of it. See Notary fees in Paris in 2026 for current rates, examples and a calculator.

Loi Carrez

The loi Carrez is the law that requires the seller of an apartment in a co-owned building to state its private floor area, measured in a defined way: floor space with a ceiling height of at least 1.80 m, excluding walls, stairwells, cellars, garages and balconies. It is the figure used to compare prices per square metre.

DPE

The diagnostic de performance énergétique is the mandatory energy rating of a home, from A (best) to G. It matters more each year: homes rated G can no longer be offered on a new residential lease since 1 January 2025, and F-rated homes follow in 2028. Many period apartments rate E or lower, so check the rating before planning to let.

Off-market

A property offered for sale privately, without public advertising. Owners choose it for discretion, to avoid an apartment appearing "stale" on listing sites, or to test a price. Access depends on relationships with owners, agencies and notaires rather than on search portals.

Chasseur immobilier (property finder)

A chasseur immobilier is a buyer's agent: a professional engaged by the buyer, under a written search mandate, to find and help secure a property. A traditional French estate agency, by contrast, is engaged by the seller.

Owning

Copropriété

Copropriété is the French form of co-ownership that applies to almost every apartment building. Each owner holds their apartment outright plus a share of the common parts. Owners vote at an annual general meeting and pay quarterly service charges (charges de copropriété). The last three years of meeting minutes are given to a buyer before signing and deserve a careful read: they reveal planned works and disputes.

Syndic

The managing agent appointed by the co-owners to run the building: maintenance, insurance, accounts and the annual meeting.

Taxe foncière

The annual property tax paid by whoever owns the property on 1 January. Paris rates are low by French standards. A second, separate tax — taxe d'habitation — still applies to second homes, with a surcharge in Paris.

SCI

A société civile immobilière is a French property-holding company, often used by families to own a home together and organise its transmission. Whether it suits a non-resident depends on their country of residence and its tax treaty with France: a question for a tax adviser before the preliminary contract, not after.

IFI

The impôt sur la fortune immobilière is France's annual wealth tax on real estate. Non-residents are liable only on their French property, above a net threshold. See the tax section of our buying guide.
