Tenancy & Legal Insights for 31 Days of Occupancy

Month-End Transitions & Full-Month Parity

When prorating 31 days, occupancy spans nearly the entire calendar month. Important statutory guidelines apply:

  • February Tenancy: 28 days in February constitutes 100% of the calendar month. In non-leap years, 28 days of rent equals the full monthly rent obligation.
  • Cap at Monthly Rent: Under residential landlord-tenant regulations, prorated rent for an incomplete month cannot exceed the total agreed monthly rent.

Step-by-Step Calculation Example for 31 Days:

Assuming a monthly rent of $1,800.00 in a 30-day month:

  1. Divide monthly rent by total days: $1,800 ÷ 30 = $60.00 per day
  2. Multiply daily rate by occupied days: $60.00 × 31 = $1,860.00

Total Prorated Rent: $1,860.00
