Real Estate Agency Boulogne-Billancourt
Real estate agency Boulogne-Billancourt and property management: Prince-Marmottan, Silly-Gallieni and Trapèze
Why PNW Partners
Your real estate agency in Boulogne-Billancourt, from the Bois de Boulogne to the Seine
Boulogne-Billancourt cannot be managed as a single block. The prestigious residential Prince-Marmottan area at the edge of the Bois de Boulogne, the Albert-Kahn gardens, the town centre and Rue de Silly, the buzz of Marcel Sembat, the renewal of the Trapèze and Île Seguin, then the Pont de Sèvres area: each neighbourhood has its own clientele and rent level. PNW Partners manages, lets and sells there with a strategy tailored to each address and a single point of contact.
Families attached to schools and parks, executives of neighbouring companies, media and technology professionals, tenants on the move: demand is varied and steady. For an owner, the right lease, a well-positioned rent and a well-presented property make all the difference.
Our agency is at 29 Avenue Trudaine, Paris 9th. Walk-ins welcome or by appointment, Monday to Friday, 9:30 am to 12 pm and 2 pm to 6 pm.

Does Paris rent control apply in Boulogne-Billancourt?

The rent is set according to the market, the address, the floor, the features and the energy performance, in compliance with the 1989 law (including annual indexation based on the IRL). However, the town is in a high-demand rental zone (zone tendue): when a new lease is signed less than 18 months after the previous tenant left, the rent may not, in principle, exceed the last tenant’s rent revised by the IRL, subject to defined exceptions (major works, clearly underestimated rent). This rule is extended until 31 July 2027. We position your rent as accurately as possible to let quickly and durably. Indicative estimate: Estimate my rent.
Which areas of Boulogne-Billancourt do you cover?
We work across the whole town: Prince-Marmottan, Parchamp–Albert-Kahn, Silly-Gallieni, Vaillant-Sembat, Reine-Mairie, the Trapèze and Billancourt, Grenier–Point du Jour and Pont de Sèvres. Each neighbourhood is analysed separately, because an apartment near the Bois de Boulogne, a town-centre property and a flat in the Trapèze call for different strategies.
Is a company lease suitable in Boulogne-Billancourt?
Yes. Boulogne-Billancourt is home to many head offices and companies in media, technology and luxury, which house executives, managers and staff on the move. A company lease falls under the Civil Code rather than the 1989 law: its duration, rent and charges are negotiated with the tenant company, whose solvency rests on the legal entity. No rent level can be guaranteed in advance.
Is a mobility lease suitable in Boulogne-Billancourt?
Yes. With its companies, its production studios and its immediate proximity to Paris, Boulogne-Billancourt welcomes professionals on assignment, interns, interim managers and employees on the move, an ideal profile for the mobility lease (1 to 10 months, no deposit). We manage these lettings with expertise and regulatory compliance, and we guide you to the right lease depending on the tenant’s length of stay.

Furnished (1 year, 2-month deposit) suits executives and professionals on the move; unfurnished (3 years, 1-month deposit) suits families. See our Furnished Rental and Unfurnished Rental pages.
