The amendment would extend the lease for five years from February 1, 2027, through January 31, 2032. The proposed initial monthly rent beginning February 1, 2027, is $48,776.80 ($1.90 per square foot), a 9% reduction from the current rent, with 3% annual increases.

Discussion:
Background
The Human Services Department (HSD) has occupied 25,672 square feet of office space at 3600 Westwind Boulevard in Santa Rosa since 2005. The current lease expires January 31, 2027. In November 2025, HSD and Public Infrastructure began negotiating an extension with 3600 WESTWIND, LLC to reduce rent as well as avoid relocation costs and service disruptions. Negotiations concluded in July 2026 and resulted in the proposed Third Amendment.
On September 15, 2026, the Board declared its intent to enter into the Amendment and authorized publication of the required notice. Following publication, the Amendment is now before the Board for final approval.
Lease Amendment
The proposed Third Amendment between 3600 Westwind, LLC and the County includes the following key provisions:
1. Five-year lease extension from February 1, 2027, through January 31, 2032;
2. Initial monthly rent of $48,776.80 ($1.90 per square foot), a 9% reduction from the prior year’s rent;
3. Annual rent increases of 3%;
4. One five-year extension option, from February 1, 2032, through January 31, 2037;
5. County responsibility for utilities in addition to rent; and
6. All other lease terms remain unchanged, including the County’s right to terminate, with or without cause, upon 180 days’ written notice.
Procedural Authority
Government Code Section 25350 requires the County to publish notice of the Board’s intent to enter into a lease or lease amendment valued at more than $50,000 once a week for three consecutive weeks prior to execution. Following the Board’s September 15 action, the County published the required notice. The Board may now consider final approval of the Third Amendment.
