Your Headquarters for Prestige, Productivity, and Possibility Welcome to Westside Professional I — a true Class A, multi-story office building located in the heart of Fairfield, California. This isn't just another lease. This is where vision meets opportunity. From the moment you enter through the building’s modern, touchless entry system into its naturally lit, contemporary lobby, you’ll notice the difference. Westside Professional I isn’t just space—it’s a statement. Designed for those who want to grow, scale, and succeed, every corner of this building has been intentionally crafted to elevate your business and your brand. Inside, you'll find expansive floor-to-ceiling windows that flood each suite with natural light. The building offers flexible suite sizes, from under 1,000 square feet to over 4,000 square feet, each with fully customizable interiors. Whether you're seeking a move-in-ready layout or need a build-to-suit solution, our team will help bring your vision to life. Generous tenant improvement packages, state-of-the-art energy management systems, and in-suite access to bathrooms, stairwells, and elevators ensure that both your team and your clients are well-supported. Fairfield is one of California’s fastest-growing counties and serves as a strategic midpoint between San Francisco and Sacramento. With Suisun Bay to the south and the wine country of Napa Valley to the west, the location offers a unique blend of affordability, accessibility, and lifestyle. Westside Professional I sits right at this intersection of business and culture, surrounded by respected law firms, wellness centers, and tech consultants who value long-term partnership over short-term leases. We’ve had tenants move in with less than 1,000 square feet and scale into full floors over time. If you’re just getting started or ready to level up, you’ll find a home here. Our flexible lease terms allow for growth without the red tape. Short-term options are available when needed, but many of our tenants stay for years—some even decades—because we prioritize relationships, not just contracts. And when it comes to amenities, Westside Professional I delivers: high-speed fiber internet, solar-powered infrastructure, EV charging stations, 24/7 access and CCTV security, and plenty of on-site parking. Brand signage options are available, and the building is conveniently located near local restaurants, coffee shops, gyms, and retail options. But what truly sets this space apart is the Weisman Commercial experience. We don’t just lease offices—we partner with you. We’ll work with your broker, your contractor, or supply our own. Our in-house management team is available to help you from the first sketch to the final walk-through. The result? A space that feels like yours from day one. If you've ever struggled with brokers who don’t return calls, listings that don’t match your needs, or buildings that feel more like storage lockers than professional space—we understand. That’s why we lead with flexibility, transparency, and integrity. We offer scalable footprints, long-term tenant improvement plans, and a willingness to think creatively to help you succeed. Over the years, we’ve hosted everything from mental health clinics and dental offices to executive coaches, CPAs, venture capital groups, and even podcast creators. Our “One Office, One Story” feature gives tenants the chance to showcase their space and share their success, building credibility while contributing to our larger tenant community. Westside Professional I is where brands grow up. Where credibility is built. Where prestige and practicality finally meet. So whether you’re a CEO searching for a headquarters, a scaling founder ready to leave the garage behind, or a team seeking a location that reflects your quality and ambition—this is your place.
