Condominium Ownership: What Renovation Works Can You Carry Out in Your Apartment?

Chapô

In a condominium, not all renovation works are subject to the same rules. Some improvements can be carried out freely within your apartment, while others require a vote at the co-owners’ general meeting.

Before starting refurbishment, thermal insulation, or acoustic insulation works, it is essential to understand the legal framework in order to avoid disputes — particularly in older or high-end buildings in Paris, Neuilly, or Boulogne.

Introduction

Works Authorized Without a Vote at the General Meeting

Properties governed by condominium status, under the French Law of July 10, 1965, must comply with the condominium regulations — the key document that governs building life and defines the rights of each co-owner.

Interior Works You May Carry Out Freely

You are free to carry out any works inside your apartment, provided they do not affect common areas or the building’s structure. The following are generally permitted without a vote:

  • replacement of individual heating systems or a hot water tank,

  • renovation or redesign of a bathroom,

  • modification of floor or wall coverings,

  • installation of a mezzanine within the existing volume.

However, it is strictly prohibited to intervene independently on structural elements such as:

  • creating a stairwell opening to connect two levels,

  • piercing a load-bearing wall,

  • any modification affecting common areas.

Works Modifying the Exterior Appearance

Any works that alter the building’s overall appearance — such as installing a roof window (Velux), replacing windows, or adding equipment visible from the outside — require prior authorization voted at the general meeting.

Works Subject to a Vote by Co-Owners

Adding Your Project to the Meeting Agenda

Works affecting common areas or the building’s external appearance must be submitted to a vote at the general meeting. You must request that the project be added to the agenda and formally present it during the meeting.

The vote is held:

  • by absolute majority under Article 25 (majority of all co-owners),

  • and if at least one-third of the votes are obtained, a second vote may be organized under the simple majority rule of Article 24.

Maintaining Good Communication During the Works

Once the works have been approved, it is strongly recommended to keep your neighbors regularly informed of progress, especially for projects generating noise disturbances or frequent use of common areas.

To secure your project, you may also take out construction insurance (“dommages-ouvrage”), which provides protection in the event of defects or damage after completion.

Tax Declarations and Impact on Property Value

Certain works, such as:

  • converting attic space,

  • installing central heating,

must be declared to the tax authorities, as they increase the property’s rental value and may affect property tax or future charges.

Description

What Is the Timeframe for Carrying Out Approved Works?

There is no legal maximum deadline for carrying out works authorized by the general meeting.

However, it is strongly recommended to wait until:

  • the two-month appeal period has expired,

this period running from the notification of the meeting minutes, which must be sent within one month following the general meeting.
