Casero vs. propietario vs. arrendador vs. dueño
When talking about renting or owning property in Spanish, you might come across the words casero, propietario, arrendador, and dueño. While all of them can be used to translate the idea of a landlord or landlady depending on the context, they carry different levels of formality, legal nuances, and everyday usage rules. Here is a breakdown to help you choose the exactly right word for your situation.
Casero
The word casero is the most common and colloquial term used in everyday conversation to mean landlord or landlady. It refers specifically to the person responsible for managing the property you rent, collecting the rent, or fixing broken appliances, even if they are not the actual legal owner.
Mi casero va a subir el precio del alquiler el próximo mes.
(My landlord is going to raise the rent price next month.)
Llamé a la casera porque la lavadora se rompió y está goteando.
(I called the landlady because the washing machine broke and is leaking.)
Tenemos suerte porque nuestro casero es muy comprensivo con los retrasos.
(We are lucky because our landlord is very understanding about delays.)
El casero nos pidió dos meses de fianza antes de mudarnos al apartamento.
(The landlord asked us for a two-month deposit before moving into the apartment.)
Ella es una buena casera que siempre envía a alguien a reparar las cosas rápido.
(She is a good landlady who always sends someone to fix things fast.)
Propietario
The term propietario translates literally to owner or proprietor and is much more formal than casero. It is widely used in real estate listings, formal meetings, or when clarifying who holds the legal deed to the property, though it can also apply to owners of businesses or vehicles.
El propietario del edificio decidió vender todos los apartamentos.
(The owner of the building decided to sell all the apartments.)

(We are looking to deal directly with the owner to avoid agency commissions.)

(The landlady gave us the keys after signing the papers at the bank.)
Solo los propietarios tienen acceso a la piscina comunitaria residencial.
(Only the owners have access to the residential community pool.)
Para tener derecho a voto en la reunión del bloque, debes ser propietario.
(To have the right to vote in the block meeting, you must be a proprietor.)
Arrendador
The word arrendador is a strict legal and administrative term meaning lessor or landlord. You will almost exclusively find this word in written lease agreements, legal documents, or court proceedings referring to the party that grants the right to use the property in exchange for payment.
El arrendador se compromete a mantener la vivienda en condiciones habitables.
(The lessor commits to keeping the dwelling in habitable conditions.)
Según el contrato comercial, el arrendador puede rescindir el trato por falta de pago.
(According to the commercial contract, the landlord can terminate the agreement for non-payment.)
Las obligaciones del arrendador y del arrendatario están detalladas en la segunda página.
(The obligations of the lessor and the lessee are detailed on the second page.)
La firma del arrendador es necesaria en todos los anexos del acuerdo.
(The signature of the lessor is required on all annexes of the agreement.)
En caso de disputa legal, el arrendador debe presentar las facturas originales.
(In case of a legal dispute, the lessor must present the original invoices.)
Dueño
The word dueño is the most general term for owner or master in everyday Spanish. While it is frequently used to refer to the landlord of a house you are renting, it strongly emphasizes the basic concept of possession and can be used for absolutely anything that belongs to someone, such as a pet, a business, or an object.
El dueño de la casa vive en otra ciudad y no suele visitarnos.
(The owner of the house lives in another city and does not usually visit us.)

(I spoke with the landlady so she would allow us to have a cat in the flat.)

(The true owner of the land has never been there to see it.)

(I have known the owner of this restaurant since we were kids.)
Mi perro es tímido y le ladra a todos menos a su dueño.
(My dog is shy and barks at everyone except his owner.)
Summary
In summary, choose casero for casual, everyday conversations about your landlord or landlady. Opt for propietario in formal or real estate contexts to refer to the deed-holding owner, and reserve arrendador strictly for legal paperwork and formal lease contracts. Finally, use dueño when you want a general, everyday word for someone who owns something, whether it is the house you rent or a personal belonging.
