2026 Law Firm Report: Trends Impacting the Industry and Real Estate

The legal sector has given us one of the clearest windows into where the office market is actually heading. Here is what the data says from the Colliers 2026 Law Firm Report.

The RTO story is real in legal, and it is accelerating.

This is the nuance that most people miss. Law firms are committing to physical space in a big way, and simultaneously taking less of it. When a firm relocates, it is cutting its footprint by 30 to 35% on average. Even firms that renew in place are trimming 10 to 15%. Only 15% of transactions result in a space increase.

The math is simple. Headcount is not shrinking dramatically, but space per attorney is. Single-sized offices are now the standard. Hoteling, which was everywhere post-pandemic, is fading. What is replacing it is something more deliberate: hospitality-oriented layouts, client-facing floors built for events, flexible seating zones, and outdoor terraces where the building allows.

The office is smaller, but it is better. And firms are spending more to make it that way.

The RTO story is real in legal, and it is accelerating.

By the end of 2026, nearly every law firm in the country will have attorneys and staff in the office more than 50% of the workweek. Professional and administrative staff are projected to be on-site roughly 70% of the time. This is not a target. It is a forecast based on where firms already are heading. Canadian firms are even further along, with major firms pushing four to five days per week in-office and some tying compensation directly to physical attendance.

The driver is not just culture. It is mentoring, associate development, and the hard reality that firms are losing ground on training when early-career attorneys spend too much time remote. The office is back as a business tool, not just a real estate obligation.

Build-out costs have changed everything.

Pre-COVID, building out Class A raw space ran about $150 per square foot. Today that number is closer to $250. That 67% jump is reshaping lease negotiations in ways that do not show up in the headline rent numbers.

TI allowances have followed construction costs higher, averaging $119.36 per square foot for a 10-year Class A lease, up from prior years. The Northeast leads at $119.87 with 11 months of free rent. The West is the highest at $139.63 with 10 months abatement. San Francisco is an outlier at $200 per square foot TI.

But here is the catch: even those record TI packages frequently do not cover the full cost of improvements. Firms are having to contribute their own capital to build-outs, which is pushing more of them toward renewals over relocations and locking in longer lease terms to justify the investment.

When a firm is putting its own money into a space, it is not leaving after five years. That is changing how landlords think about retention, and how firms think about commitment.

Long-term leases are back. 10 years is the new normal.

Seventy percent of relocation deals are being signed at exactly 10 years. Another 30% go longer. The short-term flexibility play that defined the immediate post-pandemic period is largely over for firms making real moves. The combination of high TI costs and landlord requirements is pulling terms back toward the longer end.

Renewal terms tend to be shorter, in the five to ten year range, particularly when firms are still working out their ideal layout and occupancy policy. Some renewals run as short as two to three years when tenant improvements are minimal. But for firms doing full reconfigurations of new space, the 10-year-plus commitment is essentially non-negotiable.

Class A CBD vacancy is beginning to turn.

The overall U.S. office vacancy rate ended 2025 at 18.2%, just below the 18.4% peak hit in mid-year. That may sound like a small move, but it marks the first real directional shift since the pandemic. More importantly, 53% of U.S. markets posted positive net absorption in 2025. Annual net absorption hit 18.6 million square feet, the strongest figure since 2019.

Class A CBD product is leading the recovery. Manhattan had its second-strongest legal leasing year on record. Dallas, Silicon Valley, and Boston all showed meaningful improvement. The vacancy gap between CBD Class A (20.3%) and suburban Class A (21.7%) is actually narrowing for the first time in years, with suburban Class A posting its first annual vacancy decline in over a decade.

Asking rents for Class A CBD space are holding at $52.78 per square foot nationally, down slightly from the 2023 cycle high of $53.72 but still about 6% above 2019 levels. Net effective rents tell a softer story because of the concessions, but the trajectory is stabilizing.

Concessions are likely peaking right now. This window is not permanent.

If you have a lease expiring in the next few years, this is arguably the best negotiating environment you are going to see. TI packages are at or near historic highs. Free rent is generous. Landlords in most markets are still competing for quality tenants and offering flexible deal structures to retain them.

That window is expected to close. Concessions are projected to peak in 2026 and gradually tighten as demand strengthens and the supply pipeline continues to contract. The U.S. construction pipeline is down to just 25.8 million square feet, a fraction of the 158 million square feet under construction at the end of 2019. Canada has seen an 85% reduction in new development over the past five years.

As existing leases get absorbed and minimal new supply comes online, landlords will face less competitive pressure. The firms that move early will lock in terms that firms moving in 2028 or 2029 simply will not have access to.

Trophy and Class A-plus space is about to get much tighter.

By 2028 to 2030, the report projects a genuine shortage of viable relocation options for large law firms. Trophy availability will tighten significantly through the end of the decade as tenants lock in longer terms and new deliveries remain scarce.

For firms in major Canadian markets like Toronto and Vancouver, this is already visible. Vacancy rates are already approaching single digits in the best downtown buildings, and there is minimal new construction projected before 2032. Those firms are being advised to begin strategic planning four to five years in advance of their lease expiration. That is not conservative advice for lawyers. That is survival planning.

Consolidation is reshaping the tenant base.

59 law firm mergers closed in 2025, up 18% year-over-year. Ten of those were cross-border deals, up from three the year before. The two largest combined Troutman Pepper with Locke Lord, and McDermott Will & Emery with Schulte Roth & Zabel. Sixteen more mergers have already been announced in early 2026.

Each merger triggers a real estate rationalization. Overlapping offices get consolidated. Redundant leases get shed. Surviving entities typically make a move into better, right-sized space. For brokers, every merger announcement is a lead.

Midsize firms are also growing faster than the largest firms right now. Corporate legal departments are shifting routine and moderately complex work to smaller firms to cut costs, with in-house counsel reporting savings of up to 40% without sacrificing capability. Demand at midsize firms grew nearly 5% in the second half of 2025. These groups have real estate needs that are often underserved.

The bottom line for anyone working the office market.

Law firms are not retreating from space. They are upgrading it, right-sizing it, and committing to it for the long term. The tenants are more sophisticated, the deals are more complex, and the window for favorable economics is narrowing. Firms that move in 2026 and early 2027 are likely to look back at this period as the best real estate market they will see for a decade.

Start the conversation early. Know the local fundamentals cold. And understand that the person signing the lease is increasingly a decision-making committee inside a corporation, not a managing partner making a gut call.

The office is not dead. It just got more strategic.

Frequently Asked Questions

FAQ #1 Q: Are law firms expanding or reducing their office space in 2026?

Law firms in 2026 are largely rightsizing — not retreating. Rather than wholesale reductions, most firms are trading square footage for quality, consolidating into smaller but premium, amenity-rich Class A and trophy spaces in prime locations. According to Colliers’ 2026 Law Firm North America Office Markets Report, the legal sector posted its second-strongest leasing year on record in 2025, with 18.6M SF of net absorption nationally. The dominant strategy is upgrading space to serve as a talent magnet and client-facing brand asset, not simply cutting costs.

FAQ #2 Q: How are return-to-office mandates affecting law firm leasing decisions?

Return-to-office (RTO) mandates are one of the most significant drivers of law firm real estate decisions in 2026. Law firms are among the professional services sector’s strongest adopters of in-office work, with most attorneys and staff returning an average of four days per week. This has renewed demand for well-located, collaborative office environments and is pushing firms toward longer-term leases in buildings that support both employee retention and client-facing use. Peak occupancy days remain Tuesday, Wednesday, and Thursday — a pattern landlords and occupiers are designing around.

FAQ #3 Q: What leverage do law firms have in lease negotiations right now?

Law firms currently hold meaningful negotiating leverage in most North American office markets, though it is narrowing in top-tier submarkets. With overall U.S. office vacancy at 18.2% and landlords eager to secure law firms as anchor tenants — given their long-term stability — firms can expect flexible lease structures, generous tenant improvement allowances, and meaningful concession packages. However, in trophy and Class A properties in markets like Manhattan, Houston, and Dallas, competition for the best space is intensifying. Firms that move decisively and engage an experienced tenant representative early are best positioned to capture both the space quality and economic terms they need.
