North Dakota permits several distinct amounts to be collected at move-in, each with its own limit, and combining them into one deposit figure is what turns a compliant arrangement into a non-compliant one.

North Dakota rules that apply here
The security deposit itself is capped at one month's rent, with narrow exceptions. A pet security deposit is separately permitted up to the greater of $2,500 or two months' rent. These are different amounts with different limits and different justifications, and a ledger holding a single combined figure cannot demonstrate that either was within its own cap.
Recording them as components also matters at move-out. A pet deposit is collected for a specific purpose, and applying it to unrelated damage or to unpaid rent is a different act from applying the general deposit. Keeping them distinct through the tenancy is what makes the eventual application defensible.
The return itself is due within 30 days after the tenant relinquishes control of the unit, with accumulated interest where occupancy reached nine months. Because the interest depends on tenancy length and the components have separate caps, the move-out calculation is genuinely multi-part rather than a single subtraction.
North Dakota 47-16-07.1 caps the security deposit at one month's rent and requires return within 30 days after the tenant relinquishes control of the unit. A PET security deposit is separately permitted up to the GREATER of $2,500 or two months' rent, which is a different limit with a different justification, so combining the two into one figure cannot demonstrate either was within its own cap.
The deposit must sit in a federally insured INTEREST-BEARING savings or checking account for the benefit of the tenant, but interest is only payable to the tenant where occupancy reached at least NINE MONTHS, accumulated and paid at the end of the agreement. The account therefore earns across every tenancy while only some create an entitlement, which leaves interest on short tenancies sitting in the account belonging to nobody. Unresolved, it makes the balance permanently exceed the sum of tenant liabilities.
