What GESIBA does

GESIBA Gemeinnützige Siedlungs- und Bau AG is a Vienna-based non-profit housing association (Gemeinnützige Bauvereinigung) founded in 1921 and 99.97% owned by the City of Vienna, structured as an Austrian stock corporation (AG). The company develops, owns, and manages residential and commercial real estate across Vienna and Lower Austria, with a current managed portfolio of approximately 29,300 residential units including the iconic Wohnpark Alt-Erlaa (~3,200 units) and an additional ~24,000 apartments built historically through GESIBA's own construction activity. Its core offerings span rental apartments (Wohnungen, 1-5 rooms), commercial premises (Geschäftslokale), and parking spaces (Garagenplätze), supplemented by specialized products including assisted-living (Betreubares Wohnen) units delivered with Caritas and heritage senior apartments on the Otto Wagner Site.

Revenue is generated through four streams: recurring monthly residential rents (averaging €8.06 gross per m², 28% below the Vienna commercial average), commercial space leases, garage/parking rentals (€64.50-€97.86/month per space), and managed property services billed to affiliated entities Wohnpark Alt-Erlaa AG, Wiener Stadterneuerungsgesellschaft (STEG), WIGEBA, and the City of Vienna. Underlying operations run on the proprietary HaVIS Kundenportal, an electronic document-delivery and tenant-self-service platform, paired with on-site caretaker (Hausbetreuer) staffing that the company highlights as a competitive differentiator.

Customer segments include general affordable-housing seekers (primary), seniors requiring assisted living, mobility-impaired tenants needing barrier-free units, subsidized municipal housing recipients (via WIGEBA), and institutional clients for property management. Distribution is direct-to-consumer through gesiba.at listings, the HaVIS portal, and newsletter outreach. The company reports an 89% tenant satisfaction rating (grades 1-2 in survey) and operates under the Corporate Governance Codex for non-profit building associations plus the Vienna Public Corporate Governance Codex.

Others

• Caritas Wien:
• CA Immo AG: Austrian real estate company with office and residential exposure including Vienna. Comparable as a Vienna-based real estate operator but focused on commercial real estate rather than subsidized housing.

Regional players

• SAGA Siedlungs-Aktiengesellschaft Hamburg: City-owned non-profit housing company managing ~140,000 apartments in Hamburg. Strong comparable in non-profit municipal housing model and scale, though operating in a different German city.
• Gewobag AG: Berlin municipal housing association managing ~70,000 apartments, owned by the State of Berlin. Comparable as a German public-sector housing operator facing similar regulatory and demographic dynamics.
• Neue Heimat Tirol: Austrian non-profit housing association operating in Tirol under the same Housing Non-Profit Act as GESIBA. Comparable regulatory and operating model but geographically focused on western Austria.

Broad incumbents

• Heimstaden AB: European residential real estate owner and manager with ~160,000 apartments across Northern Europe. Comparable in scale and residential focus, though operating in different geographies.
• Vonovia SE: Europe's largest residential real estate company with ~550,000 units across Germany, Austria, and Sweden. Comparable in residential rental operations and Austrian exposure but operates on a commercial, listed basis.

Direct peers

• Wiener Wohnen: City of Vienna's in-house municipal housing department managing ~220,000 apartments directly. Most direct comparable given shared municipal ownership, non-profit mandate, and Vienna-only operating focus.
• Sozialbau AG: Austrian non-profit housing association active in Vienna and Lower Austria developing and managing subsidized rental apartments. Closely comparable in legal structure, tenant base, and regulatory framework.
• BUWOG Group: Austrian residential real estate company developing and managing rental and condominium housing across Vienna and other Austrian cities. Comparable in scale and product offering though operating on a commercial (for-profit) basis.
