Rental management and accounting: legal obligations of the lessor

Updated March 29, 2026 - Rental management is not limited to collecting rent. The lessor must follow practical, documentary and sometimes fiscal obligations: management mandate, receipts, maintenance, security, recoverable charges, monitoring of rents and archiving. In 2026, good management begins with proof.

The owner must in particular:

• ▸supervise the relationship with the agency via a management mandate if it delegates;
• ▸provide a receipt if the tenant requests it;
• ▸ensure the proper functioning of the smoke detector upon entering the premises;
• ▸monitor rents, charges and regularizations.

To complete, see End of rental management mandate: what every owner needs to know, LMNP and SIRET: mandatory or not? and How to choose an accounting firm with expertise in LMNP under the real regime?.

Even without commercial accounting in the strict sense in all cases, a lessor has an interest in documenting:

• ▸rents received;
• ▸charges;
• ▸management fees;
• ▸taxes;
• ▸works ;
• ▸rental balance and supporting documents.

• ▸do not keep supporting documents;
• ▸confuse recoverable and non-recoverable costs;
• ▸delegate management without re-reading the mandate;
• ▸ignore basic obligations regarding receipt, security or monitoring of unpaid debts.
