In May 2026, a German court rejected a €6.40-per-month surcharge sought by landlord Vonovia in Dortmund, while Austrian tenants in Vienna secured a €25,000 refund after complaints to the arbitration board. June saw an audit in Carinthia that uncovered billing errors in two-thirds of 813 complexes, prompting refunds such as an €18,000 credit in Klagenfurt, and a Frankfurt student flat was repaid €26,700 after the city housing office ruled rents had more than doubled the legal limit. A July consumer-association report on French student housing found 95% of studio listings in six cities breached rent-cap rules, with landlords exploiting short-term mobility leases and furnished-rental formats to sidestep caps. By mid-July, Paris’ experimental rent-control scheme faced uncertainty as energy-performance rules threatened to shrink the supply of older units. In July, a Paris court issued a landmark €440,000 fine against a property owner and a management firm for operating unauthorized short-term rentals on Airbnb. The penalty, split equally between both parties, was calculated to exceed the approximately €410,000 in profits generated from the illegal activity. By August 2026, France tightened its short-term rental regime. Authorities warned that undisclosed sub-letting of a primary residence constitutes a serious breach. Landlords can terminate leases immediately, evict tenants, and recover all rental income earned from the illicit sub-let. The new guidance emphasizes obtaining explicit landlord consent, respecting rent caps, and complying with local tax and housing regulations, adding enforcement pressure to the broader pattern of short-term contracts being used to evade rent controls across Europe. ## Claims - A French court imposed a total fine of 440,000 euros on a property owner and a management company for illegal short-term rentals.
