IQ Bau

What IQ Bau does

IQ Bau Gesellschaft für innovative Bautechnik mbH is a Berlin-based, privately held property management firm founded in 2006 that administers residential rental apartments, commercial units, WEG homeowner communities, and special property ownership on behalf of property owners across Berlin and surrounding Brandenburg cities (Falkensee, Nauen, Strausberg, Frankfurt Oder). The company describes itself as a mittelständisches Unternehmen with approximately 30 employees and operates from a Charlottenburg headquarters plus public-facing offices in Friedrichshain and Spandau, with a handyman hub in Marzahn. Each managed building is supported by a dedicated property manager and janitor team reachable directly by clients and tenants.

The firm has progressively expanded its service scope beyond traditional Hausverwaltung. Beginning in 2016 it internalized facility and trade services — green area maintenance, waste management, and in-house trades covering heating/sanitary, painting, carpentry, flooring, and electrical installations — enabling faster response without external subcontractor coordination. More recently it added complex construction services (modernization, pipe replacement, new construction) and the build-and-operation of energy generation systems such as combined heat and power plants, photovoltaics, and contracting arrangements. The customer interface for tenants is delivered through the Faciloo digital tenant portal (facilioo.iqbau.com) and the IQ Bau mobile app, which provide self-service maintenance requests, damage reporting, digital correspondence, and real-time order status tracking at no charge to tenants, with login credentials distributed by post.

The revenue model is anchored on recurring property administration fees from property owners (subscription-like based on managed units) supplemented by recurring facility management contracts and project-based revenue from craftsman services, modernization, and construction work. Pricing for owner-side services is negotiated individually and not publicly disclosed. Go-to-market is sales-led and direct, with B2B acquisition of property owners via local offices and referrals, and B2C tenant engagement through the portal/app plus Immowelt apartment listings for occupancy within the managed portfolio. The disclosed technology stack is conventional (Strato hosting, Google Fonts/Maps, iThemes Security, Real Cookie Banner) with GDPR-compliant data handling; no AI/ML, API, or SDK capability is in evidence. Joachim Fritz serves as managing director (Geschäftsführer), and the firm is registered as HRB 79538 at AG Charlottenburg.

Broad incumbents

• Vonovia SE: Germany's largest residential property company and a dominant owner/manager of Berlin rental housing - competes with IQ Bau for third-party management mandates and sets the baseline for tenant-portal and energy-retrofit expectations in the German market.
• Deutsche Wohnen SE: Large Berlin-focused residential property owner and manager (now under Vonovia) - relevant benchmark on WEG and large-tower residential management complexity in IQ Bau's primary market of Berlin.
• Apleona Group GmbH: One of Germany's largest facility and property management firms offering integrated FM, technical building services, and energy solutions across commercial and residential real estate - a scaled incumbent against which IQ Bau competes on mid-market and regional deals.
• Dussmann Group: Large German facility services and building management group including Dussmann Service which delivers janitorial, security, and technical FM - overlapping with IQ Bau's Hauswartservice and technical maintenance capabilities at materially greater scale.
• STRABAG Property and Facility Services GmbH: Subsidiary of STRABAG SE providing technical facility management, commercial property management, and energy services across Germany - comparable on the facility/energy side of IQ Bau's offering but at significantly greater scale.
• WISAG Facility Service Holding GmbH: Major German facility services group providing technical building management, janitorial services, and energy-related offerings - directly comparable to IQ Bau's combined PM-plus-FM-plus-trades proposition, particularly for larger commercial and residential portfolios.

Regional players

• Berlinovo GmbH: State-owned Berlin residential property manager with a large Berlin portfolio, operating in the same city and tenant segments as IQ Bau - a useful benchmark on local market dynamics and pricing for managed residential units.

Direct peers

• Condata Hausverwaltung GmbH: German property management firm specializing in WEG and rental administration for residential and commercial portfolios, comparable to IQ Bau's core Immobilienverwaltung (Mietwohnungs-, Gewerbe-, WEG- und Sondereigentumsverwaltung) service line.
• Gegenbauer Services GmbH: Berlin-headquartered facility management and building services company offering janitorial, green-space, and technical building services - directly comparable to IQ Bau's Hauswartservice/Grünpflege/Handwerker offering in the same Berlin metropolitan market.
• ACCURATA Immobilien AG: Mid-sized German property management and facility services firm offering residential and commercial administration plus trades and energy services - structurally comparable to IQ Bau's integrated PM/FM/craftsman model across multiple German markets.
