SILL SA Société Immobilière Lausannoise pour le Logement

A housing organization serving the Lausanne region

SILL SA (Société Immobilière Lausannoise pour le Logement) is a semi-public real estate organization based in Lausanne that owns and manages residential buildings throughout the canton. Founded as a public partnership, the organization has expanded significantly since 2014, developing new housing across several major projects. The organization is government-backed and operates with a mandate to provide stable, quality residential housing for the region. SILL operates as an institutional landlord rather than a private property owner, which means governance structures, audit oversight, and transparency are built into the model. The organization's governing board includes elected representatives, and their operations are periodically audited by municipal financial authorities who report on governance quality and management efficiency. This institutional backing makes SILL a notably stable counter-party for a rental agreement.

What it offers to someone arriving

For a family or individual relocating to Lausanne seeking rental housing, SILL offers stable long-term residential options within established neighbourhoods. The organization manages completed buildings ready to rent now, with no waiting lists or special priority systems mentioned on their site. Arrivals can rent directly from SILL without Swiss employment or residency permits, making it accessible for new relocants. Unlike private landlords, SILL's rental agreements follow standardized terms, and the organization has transparent contact procedures for inquiries. The organization's scale means buildings typically include shared amenities and professional management on-site, so maintenance requests have an institutional channel rather than relying on an individual property owner's responsiveness. For a relocating professional concerned about landlord accountability, SILL's public governance and internal audit oversight offer a measure of recourse and predictability unusual in Swiss private rentals. The organization's portfolio spans price ranges and neighbourhood types, from Lausanne's central business areas to emerging residential developments, so different segments of the relocating market can find suitable stock. The Plaines-du-Loup development, in particular, is marketed toward families, with schools and public gathering spaces integrated into the design.

Portfolio and projects in Lausanne

SILL manages housing across several major developments. The Plaines-du-Loup eco-quartier, which opened in phases starting 2022, now houses 2,500 residents and includes 148 apartments managed by SILL in partnership with cooperatives. SILL delivered its own units at route des Plaines-du-Loup 51a, 51b and 53, totaling 104 apartments. The organization also owns three buildings acquired in 2026 on avenue Jomini and avenue Béthusy in central Lausanne, with a fourth acquisition holding 112 apartments in rights of superficie (a Swiss legal structure similar to a long lease). The site does not list individual apartment sizes, prices, or available units, so inquiries must go directly to their office. Buildings completed between 2014 and 2023 were constructed to strict energy standards. The organization publishes energy performance reports showing significant reductions in power consumption since renovation. Apartments built in the recent projects include modern kitchens and bathrooms installed during renovation, with electrical and heating systems upgraded to current codes. Heating is via district heat systems where available. The site mentions each building has laundry rooms for resident use. Lifts were installed in the newer buildings during the 2022 renovation phase. SILL is also developing additional housing capacity: in 2026, the city of Lausanne selected SILL as one of fifteen investors for new housing in the Plaines-du-Loup's second sector, representing 1,200 additional apartments and commercial space planned for completion starting 2028. This demonstrates ongoing expansion and confidence from municipal authorities in SILL's execution and financial stability.

What the site does not address

SILL's site does not publish rental prices for any unit, making it impossible to budget before contact. The site does not specify apartment sizes in terms of rooms or square metres, so prospective tenants cannot estimate suitability for their household. The organization does not explain how to apply for an apartment or what documentation is required from foreign arrivals, so applicants must navigate this through email or phone without a published procedure. The site does not confirm whether English-speaking staff handle inquiries, which creates a language barrier for non-French speakers. There is no English-language version of the site, so non-French speakers will need translation or to hire a relocation agent to navigate the process. The site does not specify typical timelines for a rental approval or move-in, so candidates cannot plan a moving schedule. Whether pets are permitted is not mentioned, nor is information on noise rules, visitor policies, or other house regulations. The site does not specify whether rent includes utilities or heating, or whether those are billed separately; this is essential for budgeting, as Swiss heating costs vary significantly by building and energy source. There is no mention of furnished apartments or short-term stays, suggesting SILL handles only permanent rentals. The site does not name individual contact people for tenant inquiries or specify response times. The organization's lease terms, cancellation conditions, and tenant rights are not published online, so applicants cannot review them in advance. SILL's current projects and planned completions are outlined, but no move-in dates are mentioned for units not yet occupied, so timing remains uncertain.

Who it suits and who it doesn't

SILL works well for relocating families or professionals seeking stability in a growing, established Lausanne neighbourhood, particularly those arriving for mid-to-long-term assignments (one year or longer). The organization's public backing and institutional scale appeals to those concerned about landlord accountability and maintenance responsiveness. The eco-quartier location suits families with children, as the Plaines-du-Loup area includes the new primary school (320 pupils) and public green space integrated into the development. Tenants valuing governance transparency and audit oversight will appreciate SILL's public financial audits and board structure. Those relocating to Lausanne for stable employment and planning to remain three years or more will benefit from SILL's expansion trajectory; new units are constantly entering the portfolio, so options will widen over time. Those arriving without French fluency will find the site alone insufficient and should contact a relocation agent familiar with SILL's procedures, or have someone French-speaking handle the initial inquiry. Short-term relocants needing furnished apartments during a house search should look elsewhere, as SILL manages only permanent rentals. Those seeking specific unit details, walkthrough videos, or rapid decisions should contact private agencies instead, as SILL's semi-public governance model moves slowly. The lack of published pricing and available units online means every inquiry requires direct contact, which deters those planning remotely or seeking self-service browsing. Budget-conscious relocants will hesitate without seeing prices; some Swiss landlords allow bidding down from list prices, but SILL's institutional model does not offer flexibility. Those seeking to negotiate lease terms or seeking furnished short-term options have better alternatives among private landlords or relocation agencies.
