The laws are built in, not bolted on afterwards.
Letting software is only as good as its legal basis. Rentprime adheres strictly to German heating regulation, German operating-costs regulation, CO₂ cost allocation, German Civil Code and current Federal Court of Justice case law.
Which laws affect utility billing?
German Civil Code governs the advance payment of operating costs and the annual billing duty. Key deadline: the bill must be delivered no later than 12 months after the end of the billing period be with the tenant — otherwise back-claims expire.
German operating-costs regulation definiert die 17 allocatable cost types: heating, water, elevator, waste, garden, caretaker, insurance, chimney sweep etc. Anything not in this list cannot be allocated.
German heating regulation §7 regulates heating cost split: minimum 50%, maximum 70% by consumption, rest by area. Rentprime offers the three common keys (50/50, 60/40, 70/30) configurable per property.
HKVO §6a since 2022: monthly consumption info to tenant is mandatory. Rentprime reminds you automatically.
CO₂KostAufG seit 2023: The CO₂ price is split between landlord and tenant per a 10-tier model — depending on building CO₂ intensity. Rentprime auto-calculates the correct tier.
