Frequently Asked Questions

On average, the process to find and lease commercial office space in the San Francisco Bay Area takes between three to six months. This timeline includes conducting a needs assessment, touring vacant office spaces, submitting Requests for Proposals (RFPs) or Letters of Interest (LOI’s), negotiating the commercial lease agreement, and completing any necessary tenant build-outs. Engaging a tenant representation broker early ensures you have ample time to negotiate the best terms without being rushed by an impending move-out date.

The cost to rent vacant office space in the San Francisco Bay Area varies widely based on the submarket, building class, and current market conditions. In the current tenant-favorable market, businesses can secure highly competitive lease rates, significant tenant improvement (TI) allowances, and periods of free rent. To get the most accurate, real-time pricing for Class A or Class B office space in specific neighborhoods like the Financial District, SOMA, or Silicon Valley, contact the team at Mainstay CRE for a custom market report tailored to your budget.

Tenant representation is a specialized commercial real estate service where a broker exclusively advocates for a business seeking to lease vacant office space. At Mainstay CRE, we manage the entire process - from identifying suitable vacant offices in the San Francisco Bay Area to negotiating the final lease terms. In a complex, high-cost market, having a dedicated tenant representation broker ensures you secure the most favorable lease terms and avoid hidden financial risks. Best of all, our services are free to the tenant; our brokerage fees are paid entirely by the landlord as part of the transaction.

When reviewing commercial lease agreements for vacant office space, you will typically encounter two main structures. In a Full-Service Gross lease, the landlord covers most operating expenses - such as property taxes, insurance, and maintenance - within your single base rent payment.

In a Triple Net (NNN) lease, the tenant pays a lower base rent but is additionally responsible for their proportional share of the building's operating expenses. The team at Mainstay CRE meticulously analyzes these lease structures during negotiations to protect you from unexpected financial liabilities.

A general rule of thumb for modern office space planning is to allocate between 150 to 250 square feet per employee. However, this depends entirely on your company's work model. A fully in-person tech company with private offices will need a higher square-footage ratio than a hybrid business utilizing hot-desking and open collaborative areas. Mainstay CRE assists clients with precise space programming to ensure you only pay for the square footage your team actually needs to thrive.
