Rent Increases in Dresden: What Landlords Need to Know

As a Dresden estate agent I regularly support landlords who want to adjust their rent — and time and again I see the same mistakes. The increase request was not formally justified correctly. The capping limit was overlooked. Or the annual waiting period was wrong. In all three cases the letter was invalid, the landlord had to start over and, in the worst case, had lost months.

This guide explains how a rent increase in Dresden works in a legally watertight way — from the correct deadline through the capping limit to the structure of the letter itself.

The three tenancy types and their different rules

Before you calculate any deadlines, check: what kind of tenancy agreement do you actually have? The answer determines which rules apply at all.

Stepped and index-linked rent: if you have a stepped or index-linked tenancy, additional increases under § 558 BGB are excluded as long as the contract runs. The increases happen automatically according to the agreed rules — that is the advantage of these contract types, but also the limit.

Standard tenancy: by far the most common form in Germany. Here all the rules of this guide apply.

The capping limit in Dresden — 15 %, not 20 %

Federal law provides for a capping limit of 20 % over 3 years (§ 558 para. 3 BGB). In cities with tight housing markets, the federal states may lower this to 15 % — and Saxony makes use of that.

For Dresden the rule is: a maximum 15 % rent increase over 3 years.

The calculation is simple: you take the rent from exactly 3 years ago (or the initial rent for more recent tenancies) and multiply it by 1.15. The result is your absolute ceiling — regardless of what the rent index would allow.

Example: rent 3 years ago: €490/month → capping limit: 490 × 1.15 = €563.50/month

If the rent-index comparative value is below this, the rent index is the limit. If it is above, the capping limit is the limit. The lower of the two values always applies.

Dresden rent index 2025

The Dresden rent index 2025 has been in force since 1 January 2025 and runs until 31 December 2026. It is based on rent data from April 2024 (4,051 analysed records) and counts as a qualified rent index within the meaning of § 558d BGB — meaning it is compiled according to recognised scientific principles and has particular evidential weight in court.

The four parameters of the Dresden rent index:

• Living area (in sqm, groups from 25 to 150 sqm)
• Year of construction (in groups, e.g. up to 1918, 1919–1945, 1946–1990, from 1991 onwards, etc.)
• Fittings level (basic, medium, good)
• Location (basic, medium, good residential location in Dresden)

You can determine the exact comparative value for your flat free of charge via the City of Dresden's official online app: www.dresden.de/mietspiegel

Whether a rent increase pays off in the long run or whether a sale would be the better option is answered by the guide Renting out or selling in Dresden.

Which flats the rent index does NOT cover:

• New-build flats that are less than 2 years old (from first occupancy)
• Furnished flats
• Flats with social-housing ties (publicly subsidised housing)
• Flats with a living area under 25 sqm or over 150 sqm

For flats outside the scope you have to fall back on comparable flats or an expert's report.

The rent cap in Dresden — what it does not do

Since 2015 the rent cap (§ 556d BGB) has applied in Dresden. It limits the initial rent for new lettings to a maximum of 10 % above the local rent-index comparative value. The Saxon ordinance runs until 30 June 2027.

But: the rent cap applies exclusively to new lettings — that is, when a new tenant moves in and a new tenancy agreement is concluded.

When increasing an ongoing rent with an existing tenant, the rent cap plays no role. Here only the rent index as a ceiling and the capping limit apply. This is a frequent misunderstanding — many landlords restrict themselves unnecessarily or miscalculate.

Calculating the annual waiting period correctly

§ 558 BGB requires: the rent must have been unchanged for at least 12 months before a new increase request can be sent. The request itself then only takes effect 3 months after it reaches the tenant.

The timeline:

Formal errors that restart the deadline: the increase request is invalid — and the deadline starts again — if the letter is not in written form, the justification is missing or incomplete, or if the new rent is not stated specifically in euros.

The rent-increase letter — the most common source of error

In my practice it is almost always the formal errors in the letter itself that make rent increases fail. Not because the figures are wrong, but because the justification is incomplete.

Written form is mandatory: the increase request must be made in writing (§ 558a BGB). A letter is the safest form. E-mail is only permitted if the tenant has expressly agreed to receive legal declarations by this route.

The three routes to justification:

Route A — rent index (recommended): you must not simply write "rent index 2025". The law and the courts require a complete, traceable classification. The letter must contain:

• The year of the rent index (Dresden rent index 2025)
• The chosen living-area group
• The year-of-construction group
• The fittings level (basic/medium/good)
• The location of the flat (basic/medium/good)
• The resulting comparative value in €/sqm
• The target rent calculated from this for your flat size

The tenant must be able to retrace your calculation themselves — this is called the transparency requirement. Anyone who states only the final result without explaining the full classification risks an invalid letter.

Route B — three comparable flats: name three specific flats with full address (street, house number, floor), living area in sqm and monthly net cold rent. Anonymous or blanket figures are not enough.

Route C — expert's report: a certified surveyor draws up a rental-value report. Costly and time-consuming — only worthwhile if the flat lies outside the scope of the rent index.

What the letter must also contain:

• The new net cold rent specifically in €/month (not just the increase of X euros)
• The effective date (3 months after receipt)
• The reference to the tenant's 2-month consideration period

The most common grounds for tenants to challenge:

1. Rent index cited, but classification not explained
2. Wrong rent-index year (outdated edition used)
3. Capping limit overlooked — increase exceeds 15 % over 3 years
4. New rent not stated specifically
5. Letter not delivered (no proof)

Securing provable delivery: an ordinary letter is not enough — you need proof of delivery. Options: personal handover with written confirmation, registered post with notification slip, or a messenger with a witness. The date of receipt is decisive, because the 2-month consideration period runs from it.

If the tenant does not agree: from the end of the 2-month period you have exactly 3 months to sue for consent (§ 558b para. 2 BGB). This time limit is a strict cut-off — anyone who misses it loses the right to the increase for this round.

Step-by-step guide to the rent increase

1. Check the tenancy type — is it a standard tenancy (§ 558 BGB)? For stepped or index-linked rent, check the other rules.

2. Check the annual waiting period — when did the last rent increase take effect? Have at least 12 months passed since?

3. Determine the rent-index comparative value — enter living area, year of construction, fittings and location into the official Dresden rent-index app. Note the comparative value in €/sqm.

4. Calculate the rent-index target rent — comparative value × living area = maximum rent according to the rent index.

5. Calculate the capping limit — rent from exactly 3 years ago × 1.15 = absolute ceiling under the capping limit.

6. Determine the permitted target rent — the lower value from steps 4 and 5 is your maximum new rent.

7. Draft the letter with full justification — explain the rent-index classification in full, state the new rent in €/month, give the effective date, observe the written form, secure provable delivery.

Example calculation

Flat in Dresden-Pieschen: 65 sqm, built 1970, medium fittings, medium residential location.

In this example the capping limit is the limiting factor — even though the rent index would allow a higher rent. This shows why it is important to check both limits.

What I advise landlords in Dresden

From my experience with Dresden owners: most rely on a single letter without consultation and are surprised when the tenant challenges it. A rent increase is not a pure arithmetic exercise — it is also a communicative act. Anyone who explains the increase request to their tenant before the formal letter arrives has a far better chance of smooth consent.

I do not handle tenancy-law disputes — that is what lawyers and the Haus & Grund association are for. But if you are unsure whether the value of your flat is in line with market developments, or whether it would make more sense to optimise the rent than to hold the property, I am happy to talk it through with you. You can calculate the current rental yield of your property yourself in advance.
