Works carried out by the landlord in an occupied dwelling raise delicate questions concerning the respective rights and obligations of the parties. Swiss lease law draws a fundamental distinction between works that the tenant is required to tolerate and those that justify a rent reduction or even termination. PBM Avocats advises and represents you in all disputes related to landlord works in Geneva and Lausanne.
The Fundamental Distinction: Urgent Works vs Improvement Works
Art. 260 CO lays down the general principle: the tenant is required to tolerate works that the landlord must carry out to preserve the property (urgent works) or improvement works, provided that the latter do not render the dwelling unfit for the agreed use. This tolerance obligation has important nuances depending on the type of works.
| Type of Works | Tolerance Obligation | Rent Reduction | Prior Notice Required |
|---|---|---|---|
| Urgent works (leak repair, heating) | Absolute obligation | Yes if significant impairment | Information as soon as possible |
| Routine maintenance (painting, minor plumbing) | Yes | Yes if notable impairment | Reasonable notice |
| Improvement works (kitchen, bathroom renovation) | Yes, unless dwelling uninhabitable | Yes during works | Formal notice, several weeks/months |
| Works rendering the dwelling uninhabitable | No — tenant may refuse | 100% if uninhabitable | Tenant's agreement or rehousing required |
The Landlord's Prior Notice: An Essential Obligation
For improvement works and major renovations, the landlord must inform the tenant sufficiently in advance (art. 260 para. 2 CO). This information must indicate:
- The nature and extent of the planned works
- The estimated duration of the work
- The foreseeable disturbances for the tenant (noise, dust, limited access to certain rooms)
- The measures taken to minimise nuisances
- The possible rent increase planned on completion of the works
Failure to give prior notice does not deprive the landlord of their right to carry out the works, but may have consequences on the right to a rent reduction and on the validity of any rent increase. It may also engage the landlord's liability if the tenant suffers unforeseen damage.
Rent Reduction during Works
The tenant is entitled to a proportional rent reduction commensurate with the impairment caused by the works, from their start until their complete completion. This reduction follows from the rules on defects (art. 259d CO), applicable by analogy to landlord works.
Indicative Reduction Calculation
| Situation | Indicative Reduction |
|---|---|
| Exterior construction noise (facade, roof) | 5 to 15% |
| Works in common areas (corridor, stairwell) | 5 to 10% |
| Renovation of one room (kitchen or bathroom unusable) | 15 to 30% |
| Several rooms simultaneously unusable | 30 to 60% |
| Dwelling totally uninhabitable (evacuation) | 100% |
The Tenant's Rights in the Face of Works
- Right to prior information on the nature, duration and disturbances of the works
- Right to a proportional rent reduction commensurate with the impairment from the start of the works
- Right to object to works rendering the dwelling uninhabitable without an offer of rehousing
- Right to replacement accommodation if the dwelling must be completely vacated
- Right to contest the rent increase after works (30-day deadline, official form)
- Right to damages if the works cause damage to the tenant's property
The Procedure in the Event of a Dispute
If the tenant and landlord fail to reach an agreement on the rent reduction during works or on other disputed points, the procedure is as follows:
- Written formal notice to the landlord (registered letter) claiming the reduction or cessation of nuisances
- Referral to the conciliation authority (Conciliation Commission in Geneva, Justice of the Peace in Vaud)
- Court proceedings before the Rental Tribunal if conciliation fails

Frequently Asked Questions about Landlord Works and Tenant Tolerance
Is the tenant required to tolerate the landlord's works?
Yes, in principle. The tenant is required to tolerate works that the landlord must carry out to preserve the property or remedy defects (urgent works), as well as works intended to improve the property or create new installations, provided that these works do not render the dwelling unfit for the agreed use (art. 260 para. 1 CO). For improvement works, the landlord must inform the tenant sufficiently in advance and in the required form. The tenant may, however, object to works that render the dwelling uninhabitable or if prior notice was not given within the statutory deadlines.
When is the tenant entitled to a rent reduction during works?
As soon as works significantly impair the use of the dwelling, the tenant is entitled to a proportional rent reduction commensurate with the reduction in enjoyment (art. 259d CO applicable by reference from art. 260 CO). The reduction is due from the start of the works until their completion. It may range from 5% for minor nuisances (exterior construction noise) to 30–50% if a room is unusable, or even 100% if the dwelling is totally uninhabitable. The tenant must notify their claim to the landlord without waiting for the works to be completed.
What prior notice must the landlord give before works?
For improvement and renovation works, the landlord must inform the tenant sufficiently in advance, indicating the nature of the works, their expected duration, the disturbances to be expected for the tenant and, if applicable, the planned rent increase (art. 260 para. 2 CO). Geneva case law generally requires notice of several weeks to a few months depending on the scale of the works. In the case of urgent works (repair of a leak, heating repair), the landlord may intervene without formal notice but must inform the tenant as soon as possible.
Can the tenant terminate the lease due to unbearable works?
Yes. If the works render the dwelling temporarily uninhabitable or intolerably impair the tenant's use, the tenant may terminate the lease extraordinarily after having put the landlord in default of offering replacement accommodation or putting an end to the nuisances (art. 259b let. a CO by analogy). This termination is an extreme recourse. The tenant may also require the landlord to offer them provisional replacement accommodation during the most significant works.
Can the landlord increase the rent after renovation works?
Yes, under certain conditions. If the works constitute genuine improvements (and not merely routine maintenance), the landlord may increase the rent proportionally to the investments made, according to the cost method (art. 269a let. b CO). The increase is calculated on the basis of interest on the invested equity and its amortisation. It must be notified on the official cantonal form. The tenant may contest this increase within 30 days. Maintenance works, on the other hand, confer no right to a rent increase.
