Rent Regulation in Dortmund: what to know
Dortmund is a designated tight housing market: the Mietpreisbremse caps new-lease rents at roughly 10% above the local comparative rent (Mietspiegel), and the reduced Kappungsgrenze limits in-tenancy increases to 15% within three years. Factor the achievable regulated rent — not the asking-rent headline — into your underwriting.
Nationwide framework: the federal Mietpreisbremse legal basis was extended to 31.12.2029 (Bundestag, June 2025); states designate covered cities by ordinance. Key exemptions everywhere: first letting of new-builds (first occupancy after 01.10.2014) and comprehensively modernised units — one reason new-build investment pairs well with regulated markets. Existing-tenancy increases are capped by the Kappungsgrenze (20%, or 15% in designated markets, per 3 years) and always by the Mietspiegel level.
