What is the maximum security deposit allowed in the Canton of Zug?

According to the Federal Civil Code, the security deposit may not exceed three months' rent. If the landlord requests a higher amount, the tenant may dispute it within 30 days with the conciliation authority. The deposit must be paid into a escrow account in the tenant's name, not the landlord's, and cannot be used to cover arrears during the lease.

How do I respond to a lease deemed disproportionate?

You have 30 days from the signing of the contract to submit a written dispute to the leasing authority of your canton. Attach documentation on the market value of comparable rentals (listings, appraisals, benchmarks). The authority will assess whether the fee is manifestly disproportionate to the characteristics of the property. If he accepts the dispute, the owner must reduce the fee; if he rejects it, the original fee remains.

What are the cancellation terms in the Canton of Zug?

The termination must meet federal deadlines: one month during the first year of the contract, two months from the second to the ninth year, three months from the tenth year onwards. The cancellation is valid only if completed via the official cantonal form and delivered to the recipient in compliance with the deadline. A verbal or incorrectly completed cancellation has no legal value.

What happens if the owner does not return the security deposit?

The landlord can deduct from the deposit only the damage ascertained to the property and the fees not paid by the tenant. If he does not return the amount within a reasonable time after the conclusion of the lease, the tenant may resort to the conciliation authority or take legal action. The deposit is tied to the tenant's account and cannot be used arbitrarily.

Do the rules on leasing vary between Swiss cantons?

No. The right to rent is governed by the Federal Civil Code (Articles 253 et seq.) and is the same throughout Switzerland. Security deposit, cancellation deadlines, dispute procedures and tenants' rights remain the same in every canton, including Zug. Cantons can provide customized official forms, but the substance of the law is federal and uniform.

Dispute Procedure and Conciliation Authority

When a tenant considers that the initial rent is disproportionate to market conditions or the characteristics of the property, they have a specific right: to file a dispute within 30 days with the cantonal leasing conciliation authority. In the Canton of Zug, as in the other cantons, this body examines the legitimacy of the request and can order a reduction of the fee if the disproportion is proven.

The dispute does not cancel the contract. The tenant remains obliged to pay the rent until a final decision is taken. If the authority accepts the dispute, the excess amount is returned by the owner; if it rejects, the original fee remains in force.

Deadlines and cancellation

The cancellation of the lease must comply with precise deadlines established by law: during the first year, the term is one month; from the second to the ninth year, two months; from the tenth year onwards, three months. The cancellation is valid only if completed via the official cantonal form and delivered to the recipient in compliance with the deadline. A verbal or letterhead cancellation has no legal value.

The owner must follow the procedure strictly. If you make formal mistakes, the cancellation is invalidated. The same applies to the tenant: the cancellation must reach the owner within the indicated period, following the procedures
