Signing a lease renewal used to be a simple formality of agreeing to a modest rent increase, but in 2026, the real cost increases are hidden in the addendums. Landlords, facing their own rising insurance and tax costs, have begun unbundling services that were once included in the rent and turning them into mandatory monthly fees. These “junk fees” can add $200 or more to your monthly housing costs, effectively bypassing local rent control caps that only apply to the “base rent.” Tenants who focus solely on the top-line number often miss these specialized clauses until the first bill arrives. Identifying these six specific “ambush” clauses before you sign is the only way to negotiate a truly flat rate for the year ahead.
