The market today

What sets office assets apart today.

Office real estate is being priced back into a new equilibrium. Tenants sign shorter, amenity expectations have moved, and build-outs are being negotiated harder than in decades. Owners who inherited a Class A office building at 2019 assumptions are looking at 2026 fundamentals.

We've managed office property across Newport Beach, Costa Mesa, and the surrounding Orange County submarkets for four decades. On office assets today, our job isn't to pretend the market hasn't changed. It's to run the building well enough that tenants stay when the lease is up, and to give the owner honest reporting when the answer is that pricing has to move.

  • Tenant experience and build-out cycles in a market where amenity spend now moves retention.
  • Multi-tenant amenity coordination — shared conference space, lobby refreshes, food-service programs where they exist.
  • Post-pandemic occupancy signals and lease-term flexibility — reporting owners can actually use to price the next renewal.
