Rent Increase Laws in Saxony (2026 Guide)

Raising rent in Saxony requires navigating a complex web of federal German laws, primarily the German Civil Code (BGB) which became effective on 1 January 1900, and state-specific ordinances. In 2025 and 2026, landlords must pay particularly close attention to the municipal location of their rental property, as rules in Dresden and Leipzig are significantly stricter than in the rest of the state.

Overview of Rent Increase Mechanisms

1. The Rent Brake (Mietpreisbremse) in Dresden and Leipzig

The Rent Brake limits how much a landlord can increase the rent when signing a new lease agreement with a new tenant.

In Saxony, the state government has designated Dresden and Leipzig as areas with a tense housing market under the Sächsische Mietpreisbegrenzungsverordnung (extended until June 30, 2027). If your property is in these cities, the new starting rent cannot exceed the local comparable rent (ortsübliche Vergleichsmiete) by more than 10% (BGB § 556d).

Exemptions from the Rent Brake

The Rent Brake does not apply if:

• The apartment was first used and rented after October 1, 2014 (new construction).
• The apartment underwent detailed modernization (making it equivalent to a new build) before the new lease.
• The previous tenant's rent was already lawfully higher than the permissible limit (the landlord may continue charging that amount).

Note: You must proactively disclose these exemptions to the new tenant before signing the lease, or they become invalid.

2. Increasing Rent to the Local Comparable Rent

For existing, ongoing leases, landlords can increase the rent up to the local comparable rent (ortsübliche Vergleichsmiete), as determined by the city's official rent index (Mietspiegel). However, this is subject to strict conditions:

1. Waiting Period (Jahressperrfrist): Under BGB § 558(1), a rent increase request can be made 12 months after the last increase, but the new rent only takes effect if the rent has remained unchanged for at least 15 months.
2. Justification: The increase must be formally justified, typically by citing the local Mietspiegel.
3. Tenant Approval: The increase does not happen automatically. The landlord must request the tenant's approval, giving them until the end of the second calendar month following receipt of the request to agree.

The Rent Cap (Kappungsgrenze)

Even if the local comparable rent justifies a steep increase, the law imposes a "cap" (Kappungsgrenze) on how much the rent can rise within a three-year window.

• Standard Cap (Outside Dresden/Leipzig): The rent cannot increase by more than 20% within three years.
• Reduced Cap (Dresden & Leipzig): Under BGB § 558(3) and the Saxony Cap Ordinance (Sächsische Kappungsgrenzenverordnung), the maximum legal increase is limited to 15% within three years. This reduced cap has been extended and remains in effect until June 30, 2027.

3. Increasing Rent After Modernization

If a landlord invests in modernizing the apartment or building (e.g., energetic refurbishments, new heating system, adding a balcony or elevator), they can pass a portion of the costs on to the tenant (BGB § 559).

• The Limit: Landlords may increase the annual rent by 8% of the costs directly attributable to the modernization (excluding any costs for pure maintenance).
• The Cap: The monthly rent cannot increase by more than €3.00 per square meter within a six-year period due to modernization. If the current rent is below €7.00/sqm, the cap is even stricter at €2.00 per square meter.
• Simplified Procedure: As of 2026, the threshold for the simplified billing procedure (vereinfachtes Verfahren) has been increased to €20,000 per apartment (BGB § 559c).
• Grants: Any state or federal subsidies (e.g., from KfW) received for the modernization must be deducted from the apportionable costs.

Crucial Step: You must announce the modernization measure to the tenant in writing at least three months before work begins, detailing the expected rent increase.

4. Index Leases and Staggered Leases

To avoid the complex calculations and justification periods associated with the Mietspiegel, landlords often use pre-defined rent increase clauses.

Index Rent (Indexmiete)

The rent is explicitly tied to the Consumer Price Index (Verbraucherpreisindex) determined by the Federal Statistical Office (BGB § 557b).

• Rent can be adjusted annually based on the percentage change in the index.
• 2026 Cap: Under the 2026 Tenancy Law Reform, annual rent increases for index-linked leases in designated tight markets (Dresden and Leipzig) are capped at 3.5%, regardless of higher CPI growth.
• It requires a written declaration by the landlord showing the calculation.
• During an index lease, rent increases based on modernization are generally excluded (unless required by law).

Staggered Rent (Staffelmiete)

The lease agreement precisely defines future rent increases as specific Euro amounts occurring on specific dates (BGB § 557a).

• There must be at least one year between each staggered increase.
• During the staggered period, no other rent increases (e.g., via Mietspiegel or modernization) are permitted.

Important Note for Dresden and Leipzig: Even with a staggered lease, each individual rent increase step must comply with the Rent Brake (max 10% above comparable rent) at the time it takes effect.

Best Practices for Landlords in Saxony

1. Check Your Location: Always verify if your property falls under the strict ordinances for Dresden and Leipzig before calculating an increase.
2. Use the Official Mietspiegel: In Dresden and Leipzig, use the qualified rent index provided by the city to justify BGB § 558 increases to ensure they stand up in court.
3. Understand the Caps: Never increase an existing rent by more than 15% over three years in the designated tight housing markets.
4. Disclose Exemptions: Always declare your Rent Brake exemption status to new tenants before handing over the contract.
