In multi-tenant offices, something is always changing: tenants come and go, floors are reconfigured, and data connections and climate systems are adjusted. Every renovation affects the fire compartmentalization between units, corridors, and shafts.
Grazy Brandwering works around existing tenants and delivers a digital logbook per building. For property managers with multiple properties, we map out the entire portfolio, with uniform reporting and a maintenance schedule.
Risks relevant to this sector
Tenant turnover
With every move-in, walls are relocated and cables are run. Without a follow-up check, breached fire separations go unnoticed until the next inspection or, worse, until a fire.
Dispersed responsibility
Owner, manager and tenant sometimes point at each other when it comes to fire safety. The Bbl has several duties of care, for the condition of the building and for its use. Who is responsible for what depends on the situation and the agreements.
Portfolio without oversight
Managers with dozens of properties often lack a uniform view of the condition of the fire protection provisions per property.

For an investor with 22 office properties, we carried out a baseline assessment, set up a digital logbook per building, and linked this to an annual inspection round with an overview at portfolio level.

- Dutch Buildings Decree (Bbl) - duties of care Art. 3.5 (condition of existing building) and 6.4 (fire-safe use)

- NEN 2767 - condition assessment (for portfolio reporting)
Questions about fire safety in offices & multi-tenant real estate
Yes. Small work is done during the day with minimal disruption; interventions in shared spaces or noise-producing work is scheduled in the evening or on weekends.
That depends on the situation and the agreements. The condition of the building is a different question from its use: the owner, the manager and the tenant who commissioned the work may each have obligations. Set out in lease and management contracts who commissions work, who repairs the fire separation and who checks it. In a dispute, legal advice is wise.
Yes: a logbook per building plus an overview across the entire portfolio - which properties are in order, where action is needed, and the multi-year estimate.
