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.

Frequently asked questions

Common questions on Southern California office property.

  • What's actually different about office property management today versus five years ago?
    Tenants sign shorter, renewals are negotiated harder, and build-out expectations have moved. Amenity spend now drives retention in a way it didn't in 2019, and lease-term flexibility (right-to-terminate, shrink options, blend-and-extend) is on the table where it wasn't before. Owners running an office building on 2019 assumptions are looking at a lease-comp set that doesn't support the reserves they planned. Our reporting is written to make that visible before it becomes a renewal-cycle surprise.
  • What's a realistic occupancy and lease-cycle expectation for OC office right now?
    Depends on the submarket, the class, and the size of the average tenant. Newport Beach and Costa Mesa Class A office is trading differently than Class B in the same submarkets; small-tenant floors are moving faster than large-plate space in most of OC. Rather than a category answer, we walk the building, look at the tenant roster, and give the owner a written read on what to expect at each upcoming renewal.
  • How do you handle tenant experience and amenity coordination in multi-tenant office?
    Shared conference space, lobby experience, on-site food or coffee where it exists, and the quiet-but-material things — cleaning quality, HVAC performance, security cover. On multi-tenant office, tenant experience is retention: the tenants who renew are the ones whose day-to-day experience of the building is uneventful. That's the standard we manage to.
  • When should we start the renewal conversation on an office lease?
    Eighteen to twenty-four months before term, longer if a meaningful build-out is part of the negotiation. Waiting until the last two quarters is negotiating with no room to move — the tenant knows the market timing as well as we do. Our frequent owner reports flag upcoming renewals early enough for a real strategy conversation.
  • What does asset management add on top of property management for an office owner?
    Portfolio-level strategy — hold, refinance, reposition, or exit — modeled from the operating detail rather than broker assumptions. In a repricing market, that scenario work is worth the most on office. Under one team, the person modeling the hold-versus-sell decision is the same person who knows what the roof and HVAC actually cost.
