Water and Electricity in Your Name After Buying in Rosarito
In Playas de Rosarito, water and sewer service comes from CESPT (Comisión Estatal de Servicios Públicos de Tijuana, the state utility that serves Tijuana and Rosarito) and electricity from CFE (Comisión Federal de Electricidad). Neither account changes hands automatically when you buy. You transfer each one yourself, in person: at a CESPT customer centre through a modificación de datos (change of owner's name), and at a CFE customer centre (Centro de Atención a Clientes) through a cambio de nombre. Do it in the first weeks after closing. Years later, when you sell, the electricity bills in your name are one of the few documents a notary can accept to prove the house is your home for the income-tax exemption.
Why it matters
Proof that the house is your home. When an individual sells their own home (casa habitación), the gain is exempt from income tax (ISR) up to 700,000 UDIS of sale price, if the sale is formalized before a notary and the other conditions are met (Ley del ISR, article 93, section XIX, paragraph a). The regulations (Reglamento de la Ley del ISR, article 155) say how you prove to the notary that the property is your home. The accepted documents are:
- a voter ID (credencial para votar) issued by INE;
- official tax receipts (comprobantes fiscales) for electricity or landline telephone service; or
- statements from banks, department stores or non-bank credit-card issuers,
showing the property's address and issued in the name of the seller, the seller's spouse, or their parents or children. Foreign owners do not have a voter ID, so in practice the CFE bill and bank statements carry the weight. Note what is missing from the list: the water bill does not count for this purpose. It is still worth having in your name, but it will not prove your home to the notary.
If your home is in a bank trust, the Federal Tax Code (article 14, section VI) treats you, the beneficiary, as the person who acquires and later sells the property, so these rules apply to you.
Control and proof of address. An account in your name means notices, cut-off warnings and payment history are yours, and you can show a bill in your name whenever an authority or bank asks for proof of address.
Debts. CESPT will not change any data on an account that has overdue balances. Before closing, ask the seller for the latest bills of both utilities and make sure they are paid.
Water: changing the CESPT account to your name
According to CESPT's published requirements for modificación de datos (updated September 2026), you go in person to a customer centre (Centro de Atención al Público). In Rosarito there is one on Blvd. Benito Juárez No. 385, Fraccionamiento Hacienda Floresta del Mar, and a mobile unit at the municipal Centro de Gobierno. For a change of owner's name you need:
- The account up to date, with no overdue balance.
- Proof of ownership. The usual option is the escritura (deed) plus a current certificate of its registration in the public property registry (RPPC) plus a predial receipt whose name and address match those documents. CESPT also lists other options, such as a court judgment or a private contract with supporting documents.
- Official photo ID of the owner. CESPT's list names a voter ID, a Mexican passport, a driver's licence or a consular ID card (matrícula consular). A foreign passport or a Mexican residence card is not on the list, so ask the centre in advance what it will accept from you.
- If someone does it for you: a power of attorney (notarial, a letter signed before a notary, or a simple letter signed by you and two witnesses with copies of their IDs), plus that person's ID.
The published fee for a change of owner is $220.02 pesos (estimate; CESPT adjusts its charges monthly for inflation). CESPT says it takes about 10 business days, and the change appears on your next bill. All documents are delivered as complete, legible copies.
If the property has no water service at all — a new house or a lot — that is a different procedure, a new contract, which starts with a CESPT feasibility inspection.
Electricity: changing the CFE account to your name
CFE's official answer on changing the account holder is short: go to the nearest Centro de Atención a Clientes with official ID, proof of the correct address, and a document showing ownership or possession. Bring the escritura or trust deed and your predial receipt, and settle any balance first.
For a new contract (or a re-contract), CFE's published requirements for household service include: your full name with official ID, the full address with cross streets, your RFC, a phone number and email, and, if someone represents you, a simple or notarized letter of authority with both IDs. A re-contract requires the account to be current. Contracting is free; CFE charges a guarantee deposit on the first bill.
Because CFE asks for your RFC, it is the natural moment to have it on the account. If you will one day sell and want the home-sale exemption, getting your RFC first and then putting the CFE account in your name, at the property's address, is the order that works.
If you own through a fideicomiso
Under the Ley de Inversión Extranjera (articles 11 and 12), a bank holds title to property in the restricted zone, which includes Rosarito, and the trust gives you, the beneficiary, the use and enjoyment of the property. You are the one who lives there and uses the services, so the contracts should be in your name, not the bank's.
Neither utility's published list mentions trusts. Two things help:
- Put the predial account in your name first. The Ley de Hacienda Municipal makes a trust beneficiary in possession the predial taxpayer (article 75 BIS A, section II). A predial receipt in your name lets the names match, which CESPT requires.
- Bring the trust deed (with its registration data) as your proof of ownership or possession, and ask the utility before you go whether it accepts it.
A short checklist
- Before closing: get the account numbers and latest bills of both utilities from the seller; confirm they are paid.
- After closing: put the predial account in your name.
- Change the CESPT account to your name at a customer centre.
- Change the CFE account to your name, with your RFC if you have one.
- Keep every bill. If you sell one day, the notary will want them.
How Rosarito Legal can help
Rosarito Legal, the Rosarito office of Galarza Legal, prepares the documents each utility asks for after a closing — trust deed, registration certificate, predial in your name, powers of attorney — and can go with you or act for you at CESPT and CFE. We also help with RFC registration for owners planning a future sale. Utility payments go directly from you to CESPT and CFE.
