For example, regular rent increases, rent increases after modernization, or rent increases in the case of stepped or indexed rents.<\/p>\n<p>In the context of regular rent increases, the rent can be raised based on the rent index or comparable apartments.

The plaintiff requested the defendant\u2019s consent to increase the net rent for an apartment rented by the defendant under a rental agreement dated 06.09.2015.<\/p>\n<p>The apartment had a monthly net rent of 1,380.00 EUR. In a letter from the plaintiff\u2019s attorney dated 26.07.2022, the plaintiff requested the defendant\u2019s consent to increase the net rent by 274.00 EUR to 1,654.00 EUR as of 01.10.2022. The letter stated that the apartment had a living area of 220 sqm, so the price per square meter would increase from 6.27 EUR to 7.52 EUR. The plaintiff cited six allegedly comparable apartments to justify the rent increase.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"In_dem_Mieterhohungsschreiben_stellte_der_Vermieter_6_vergleichbare_Wohnungen_vor\"><\/span>In the rent increase letter, the landlord introduced six comparable apartments.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The defendant argued that the comparable apartments mentioned in the rent increase request were not comparable, not sufficiently specified, non-existent, or not comparable. Additionally, the apartment was not located in the city center but only in the core city and had an area of only 184.36 sqm.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Nachdem_der_Mieter_nicht_zustimmte_verklagte_der_Vermieter_ihn\"><\/span>Since the tenant did not agree, the landlord sued him.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Thus, the defendant did not consent despite the deadline set. Therefore, the plaintiff sued the defendant in the District Court of Friedberg for consent to the rent increase.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Urteil_des_Amtsgerichts_Friedberg\"><\/span>Judgment of the District Court of Friedberg<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Das_AG_Friedberg_sah_das_Mieterhohungsschreiben_als_unwirksam_an\"><\/span>The court found the rent increase letter to be invalid.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The District Court of Friedberg ruled that the rent increase request dated 26.07.2022 did not meet the requirements of \u00a7 558a paragraph 1 sentence 1 of the German Civil Code (BGB). It was formally invalid, and the lawsuit based on it was therefore inadmissible.<\/p>\n<p>According to \u00a7 558a paragraph 1 BGB, the request for a rent increase must be explained and justified to the tenant. The justification should enable the tenant to verify the factual legitimacy of the increase to avoid unnecessary litigation. For this, it is necessary that the justification provides the tenant with concrete information about the factual legitimacy of the increase so that they can evaluate the legitimacy during the consideration period and decide whether to agree or not. Although excessive demands should not be placed on the justification requirement concerning the landlord\u2019s fundamental right under Article 14 of the Basic Law (property guarantee), the request must, in formal terms, include details of the facts from which the landlord derives the justification for the requested rent increase. This must be sufficient for the tenant to at least partially verify the legitimacy of the increase. This was not the case here.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Es_mussen_mindestens_3_Vergleichswohnungen_genannt_sein_die_genau_bezeichnet_werden_mussen\"><\/span>At least three comparable apartments must be named and clearly specified.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In the case of a rent increase based on comparable apartments, the addresses, floor levels, and positions on the floor (left, right, etc.) must be so precisely provided that the tenant can easily locate them without independent research. Therefore, comparison object No. 2 was deemed unsuitable as the address did not exist in Bad Nauheim. Furthermore, the apartments must be comparable.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Vier_der_sechs_Vergleichswohnungen_des_Vermieters_seien_nicht_vergleichbar\"><\/span>Four of the landlord\u2019s six comparable apartments were not comparable.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>A generous standard must be applied. The mention of comparable apartments in a rent increase request is not intended to prove the local comparable rent but to give the tenant an indication of the legitimacy of the request, allowing them to at least partially verify the rent increase. The law only requires that the apartments be \u201ecomparable\u201c and not \u201ecorresponding\u201c or \u201eidentical.\u201c However, the comparable apartments must not belong to a different residential sub-market upon evaluation. Such sub-markets include, for example, small apartments, large apartments, luxury apartments, standard apartments, comfort apartments, simple apartments, single-family homes, penthouses, etc.<em>Comparable<\/em>\" and not \"<em>accordingly<\/em>\" or \"<em>Identical<\/em>\" must be. However, the comparative flats should not belong to a different housing submarket according to an evaluative approach. This would include, for example, small flats, large flats, luxury flats, standard flats, comfort flats, simple flats, detached or semi-detached houses, penthouse flats, etc.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Im_Ergebnis_sei_das_Mieterhohungsverlangen_unwirksam\"><\/span>In conclusion, the rent increase request was invalid.<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It was undisputed that comparison object No. 1 was a commercial property. Comparison objects Nos. 5 and 6 were undisputedly single-family homes or terraced houses. Therefore, only comparison objects Nos. 3 and 4 could possibly serve as a basis for the request, meaning that the required number of three comparable apartments was not met, rendering the rent increase request invalid.<\/p>\n<p>Source: District Court of Friedberg<\/p>\n<p><strong>Important Note: The content of this article has been prepared to the best of our knowledge and belief.
