Working as a team affords us distinct advantages over agents and brokers who work individually. We bring to the table a broad set of skills that allow us to provide not only cutting-edge marketing for our clients’ assets but also a deep understanding of the tenant pool, including requirements under 10,000 square feet, that fit their building.

Our Approach

We use a proactive marketing approach in identifying and securing new tenants for our clients. That approach includes the following:

1. We invest in our clients’ projects by providing cutting edge specific building branded websites, drone exterior and interior videos, professional photos, and 3D virtual tours to pre-qualify any potential tour candidates and provide maximum marketing exposure for the listing.

2. Leveraging the marketing over multiple platforms such a CoStar, LoopNet, Craigslist, Crexi, Tenx, etc.

3. Unlike other firms and leasing teams, we actively track tenants in market under 10,000 square feet and identify tenants either by preferred industries, similar square footage and/or buildout requirements as our listings in order to reach out to tenants on a direct basis.

4. We engage the brokerage community on a weekly basis with our marketing in the form of broker blasts and direct follow up concerning potential tenants they have in or coming to market.

5. Weekly reporting to our clients tracking both inbound inquiries, tours and direct tenant out-reach.

Testimonials

John Ortesi

Property Manager, Wildis North America Corp.

Our real estate organization needs to always be prepared to navigate the ever-changing real estate market. Therefore, it is essential to have real estate professionals that can cater to our requirements by forecasting emerging trends, offer market insights, identify favorable opportunities or pitfalls and, most importantly, provide steady, sound and reliable advice.

In this regard, we are pleased to have a very good existing business relationship with Jim Walker and Scott Vix of Kidder Mathews who handles our office leasing at our property in San Francisco, CA. Through our interactions with both Jim and Scott, they have been responsive, responsible, dedicated and hard working. These good qualities and their ability to effectively communicate and collaborate with other real estate professionals, which is the outcome of their many years of experience and business connections in the real estate industry, resulted in our property attaining optimal rent and, most importantly, attaining 100% occupancy.

I would highly recommend Jim and Scott to any real estate organization that they might represent in the future. I am confident the said organization will receive the same good qualities, care and attention that we have experienced with them.

Katherine Bella

Chief Executive Officer, Mechanics’ Institute

The team at Kidder Mathews has been a delight to work with. We began our partnership as our organization began coming out of the pandemic, with many of our offices needing to be leased as a result of changing work patterns of Bay Area professionals. Through a comprehensive understanding of our institution, Class B historic buildings, the financial district neighborhood, and the changing factors in the market, Paul, Jim, Scott and Bruce have made a great impact for us. In a neighborhood that currently still carries a 60% occupancy rate, ours is at 80% and climbing. We have a building filled with happy and interesting tenants and a revenue stream that allows us to sustain and grow as a San Francisco nonprofit.

Marty Smith

President & Owner, Alhouse Deaton

I’ve worked with Jim for many years as the leasing broker for several of the properties that we manage in San Francisco. He and his team are really pros. They understand the market and more specifically the properties that are the direct competition to our buildings. Most important, they deliver results fast and keep our buildings full. Their attentiveness to our properties is greatly appreciated by our management team and the property owners. It’s great working with Jim. I would recommend Jim and his team to anyone.

Sandi Hyman

Folsom Properties

The words leasing broker can sometimes conjure up a sense of dread however, working with Scott Vix over the past 10 years has been an exception to the rule. Prior to Scott assisting our family real estate portfolio, assistance was pitiful. He has been the consummate professional from day one.

Not only did Scott take our occupancy from 75% to 100%, he did it with integrity and respect for all parties utilizing his exceptional verbal and written skills. Even after tenant transactions were complete, tenants always spoke highly of Scott's abilities.

In my experience, Scott has proven himself to be an honest and hard­working man who also happens to love his family. I trust him without hesitation and would highly recommend him.

Bay Area Market Reports

San Francisco Office Report Newsletter

Q1 2025 Market Overview

Q1 San Francisco office numbers present a “mixed bag.” On the one hand, leasing activity posted its strongest quarter since 2019, on the other, negative absorption returned in Q1 (approximately 700,000 square feet). The negative absorption is due in part to multiple large block vacancies like Twitter at 1355 Market.

Tenants in the market (TIM) requirements for Q1 stood at 6.4 million square feet, down slightly from 6.5 million square feet in Q4, 2025. City wide vacancies this quarter increased by 50 basis points and currently stand at 35.5%. The Kastle “back to work” barometer showed a recent four-week peak usage average of 50.5%. Signifying the first time since COVID that office occupancy has crossed the 50% threshold for San Francisco.

Leasing activity for Q1 2025 totaled 2.8 million square feet, up from the 2 million square feet leased in Q4, 2024. The market activity continues to be driven by tech. Pre-Covid, tech made up 50% of all tenants in the market. At the end of Q1 they represent almost 49% of current leasing requirements.

“Flight to quality” both qualitative and geographical continues to be the trend with Class A projects accounting for over 80% of all lease transactions in Q1, and North and South Financial districts accounting for the majority of leasing activity. Several large leases closed in Q1, including the 555,000 and 280,000 square foot renewal/expansion for Google and JPMorgan and the 150,000 square foot new lease for Databricks. With that, over half of all lease transactions in Q1 were under 5,000 square feet.
