San Juan

About San Juan:

San Juan covers about four and a half square kilometres directly south of the canton seat, and at 1,045 metres it is the lowest ground in Santa Bárbara. The Porrosatí River marks its line with the central district. Two national roads cross it: Ruta 123, the main way in and out of Santa Bárbara towards Heredia, which carries on through San Joaquín, Barrantes and Llorente de Flores, and Ruta 119, which runs from Río Segundo de Alajuela through San Juan towards San Roque and Barva. In September 2025 the municipality opened Calle Los Mora, a new road that links San Juan directly with San Pedro de Barva. Buses on the Heredia–Santa Bárbara por San Juan line and the Alajuela–Río Segundo–San Juan de Santa Bárbara line serve the district.

San Juan was one of the districts that made up the canton when it was created on 7 December 1848, and its first chapel went up in 1852. In 1914 the canton’s first hydroelectric plant started running here on the Porrosatí, and in the 1920s, under President Ricardo Jiménez, the district got piped water from the Potrerillos River. Coffee has always been the main crop, and for years a sawmill made timber the second trade. The old La Meseta coffee mill now belongs to the Municipalidad de Santa Bárbara, which plans to use its buildings for public projects. For everyday needs there are restaurants, pulperías, an EBAIS health post and a private home for the elderly.

Being low ground has a downside. The Zanjón River, Quebrada La Claudia and the Porrosatí all run through the district, and in the rainy season water collects where the drains cannot keep up. In May 2014 more than a hundred houses took water after a downpour hit blocked culverts, and heavy storms still flood some streets. For a buyer, that turns into a few practical checks: how the street drains, whether the house sits above or below road level, and how close the nearest quebrada runs.

San Juan had 507 residents in 1883 and 3,502 in 1984; by 2011 the count was 7,662, and the estimate for 2022 is close to 8,700. Most people live in San Juan Abajo, the head town, and in San Juan Arriba, with Cinco Esquinas, Lotes Moreira, Tierra Santa, Calle Zapote, Las Rosas and the Villa Margarita and Samarcanda urbanizaciones around them. Buyers are mostly Costa Rican families, many of them working in Heredia, Alajuela or the free zones along the General Cañas highway. Newer condominiums have also brought in first-time buyers who want a gated house rather than an apartment.

Houses in San Juan:

The typical home is a one-storey house on its own lot, either in an urbanización like Villa Margarita or Samarcanda or along the older streets of San Juan Abajo, where some houses cover their whole plot. Residencial Málaga is a gated condominium of one-storey homes on lots of around 200 square metres, usually with three bedrooms, two bathrooms, a terrace and parking for two cars, plus a monthly condominium fee. Condominio Avenue is smaller still: fifteen new houses with three bedrooms and 163 square metres of living space on 188-square-metre lots. Older quintas with gardens come up as well, for buyers who want houses for sale in San Juan de Santa Bárbara with more outdoor space.

Rentals in San Juan:

Most rentals are whole family houses. One-storey homes with three bedrooms and about 250 square metres are offered on the strength of the short drive to the airport, and houses inside Residencial Málaga rent to tenants who commute to Heredia, Alajuela or the free zones. There are also rooms and a few small apartments let by local owners, often with water, power and internet included. Ask whether the condominium fee is in the rent, and whether the house has its own parking.

Land and Lots in San Juan:

Land in San Juan tends to come in large pieces rather than single house lots. One parcel of about 9,400 square metres with more than 100 metres of road frontage has a land-use permit for housing, commerce, services and warehouses, and can be split into lots of 120 square metres or more. Elsewhere, blocks of 11,000 to 12,000 square metres have been offered together as a single tract of over 46,000 square metres. These are development sites, so the questions are about water availability, river setbacks and what the municipal plan allows before price. If you are looking at land for sale in San Juan, ask for the uso de suelo certificate first.

New Developments in San Juan:

Naala is the project that is changing the district fastest. It is a condominium on a ten-hectare site about 1.5 kilometres north-west of the Vindi store in San Joaquín, built in two stages and handing over homes in phases. The models are two- and three-bedroom houses of around 108 to 114 square metres, with a garden and parking for two cars, and the shared areas being built include a pool and jacuzzi, barbecue ranchos, a playground, a dog park and an outdoor gym. Condominio Avenue adds its fifteen new houses at a much smaller scale. Neighbours have raised concerns about traffic and street damage from the construction, so drive the route at rush hour before you reserve new homes in San Juan.

FAQ:

• Which San Juan is this, and what neighbourhoods does it include?

  This is San Juan de Santa Bárbara, district three of Santa Bárbara canton in Heredia, postal code 40403. Costa Rica has many places called San Juan, so check that the address on the deed or plan says Santa Bárbara de Heredia. The district takes in San Juan Abajo, San Juan Arriba, Cinco Esquinas, Lotes Moreira, Villa Margarita, Samarcanda, Tierra Santa, Calle Zapote and Las Rosas.

• Does flooding affect property in San Juan, and what should I check before I buy?

  Low streets can flood in heavy rain, mostly where drains back up, so visit during the rainy season and look at the kerbs, culverts and the level of the floor against the road. If the lot touches the Zanjón, the Porrosatí or Quebrada La Claudia, the protection strip along the bank limits where you can build. Then ask the Municipalidad de Santa Bárbara for the uso de suelo certificate, and check at the Registro Nacional (Registro Inmobiliario) that the cadastral plan matches the registered property and that no liens are recorded.

• How do I get from San Juan to Heredia, Alajuela and the airport?

  Ruta 123 takes you through San Joaquín de Flores towards Heredia, and Ruta 119 heads south-west to Río Segundo, close to the airport and the General Cañas highway. Calle Los Mora, opened in 2025, is a shortcut to San Pedro de Barva. Without a car, use the Heredia–Santa Bárbara por San Juan buses or the Alajuela–Río Segundo–San Juan line.

• What schools and health services are nearby?

  The main public primary school is Escuela Tranquilino Sáenz Rojas. Colegio Bilingüe Nueva Esperanza, founded in 1993, and Puente Verde are private options inside the district. Most teenagers go to the public high school in Santa Bárbara or to schools in Alajuela, and the EBAIS in San Juan covers basic medical care.

• Is water supply a concern with so much new building?

  It is worth asking. Residents have questioned how the district’s water and roads will cope with the new condominiums, so for a new home ask the developer for the water availability letter, and for a resale ask whether the house has a storage tank. For land, the availability letter matters more than the asking price, because the building permit depends on it.
