Can my landlord raise the rent after several years on the contract?

When a tenant has been in the same apartment for several years, the most common question as renewal approaches is always the same: how much can my landlord raise the rent? In Mexico the answer depends mostly on three factors: what the contract says, the civil code of the state where the property is located, and the willingness of the parties when signing the extension.

What the law says in Mexico

Residential leases are regulated by state civil codes, not by a single federal law. In Mexico City, for example, the local Civil Code sets out the rules for lease contracts in articles 2398 to 2447; in Nuevo León, Jalisco or Estado de México there are equivalent regulations with small nuances.

Three key ideas apply almost everywhere in the country:

• The minimum term for a residential lease is one year, unless agreed otherwise.
• The rent can only be updated under the terms set out in the contract. If no escalation clause was agreed, the landlord cannot raise the rent unilaterally during the term.
• When the term ends, both parties are free to renegotiate. If there is no agreement, the contract terminates and the tenant must hand back the property.

During the contract: the role of INPC

Almost every modern contract includes a clause that ties the annual update to the Índice Nacional de Precios al Consumidor (INPC) published by INEGI. It is the most widely used reference because it is public, monthly and easy to verify.

A realistic example: in July 2025 you sign a contract for $18,000 MXN per month in a neighborhood in Benito Juárez, CDMX. The clause says the rent will be adjusted every 12 months by the INPC. If the annual inflation as of the close of June 2026 is 4.2%, the new rent will be:

$18,000 × 1.042 = $18,756 MXN/month.

If the contract sets a fixed percentage (for example 6% per year) that is the cap, even if inflation is lower. What the landlord cannot do is invent an increase higher than what was agreed or apply it before the anniversary date.

Written notice

Although most civil codes do not require a specific notice period for a contractual update, good practice (and almost every well-drafted contract) calls for notifying the tenant 30 days in advance, in writing or by email. That avoids disputes about the date when the new rent takes effect.

At renewal: free negotiation

Once the term ends, the landlord can propose any new rent. There is no legal cap: if the apartment has appreciated because the area has gone up in value (a typical case in Roma–Condesa, Polanco, San Pedro Garza García or Providencia in Guadalajara), it is perfectly legal to propose an increase well above the INPC.

The tenant has three options:

1. Accept the new rent and sign the extension.
2. Negotiate an intermediate figure, usually together with property improvements or a longer two- or three-year term.
3. Decline, vacate and find another place.

Step-by-step process if there is no agreement

1. Check the exact expiration date of your contract and the renewal clause: many contracts roll over tacitly for one year if neither party gives 30 days' notice.
2. If the landlord delivers a non-renewal notice or an increase proposal, respond in writing within a reasonable timeframe.
3. If you decide to vacate, prepare a key-handover record with an inventory and photos so the deposit return is not complicated.
4. If the landlord insists on charging rent above what was agreed during the term, you can go to the Procuraduría Federal del Consumidor (Profeco) or, in CDMX, to the Procuraduría Social, before filing a civil lawsuit.

Practical case: Monterrey, 2026

A family signed a $14,000 MXN/month contract in San Pedro in 2021 with an INPC update clause. After five years, the landlord proposes renewing at $22,000 MXN, arguing that similar apartments in the area rent today in that range. The family hires an independent appraisal, confirms that the market rent is between $19,500 and $21,000 MXN, and closes a two-year extension at $20,500 MXN. Negotiating with data always pays better than negotiating with emotions.

Before signing the next renewal

• Ask in writing for the breakdown of the increase: percentage, reference index and effective date.
• Verify the INPC published by INEGI for the relevant month.
• If you plan to stay several years, it is worth setting the update with a cap (for example, "the lower of INPC and 7%").
• Document the apartment's condition when signing the extension: this prevents pre-existing damage from being deducted from your deposit at the end.
