San Mateo County has adopted a local business preference ordinance; proposers designated as local businesses, local non-profits, small businesses, or micro businesses may receive preference points of 5 to 10 percent depending on classification.

The vendor must use only original equipment manufacturer parts, employ service personnel trained and qualified by the manufacturers, and comply with manufacturer recommendations and industry standards. Proposers must demonstrate four years of experience providing similar services within the last seven years and an account manager with two years of account services experience within the last five years.

The initial contract term is one year, with two optional renewal periods of up to one year each, exercisable at the County's sole discretion with thirty days' written notice. Pricing proposals must itemize preventative maintenance, travel fees, freight, and consumables for each service visit, calculated at 9.375 percent sales tax. Evaluation weighting is project approach (30 percent), firm qualifications (25 percent), team qualifications (20 percent), and price (25 percent). Questions and comments are due September 4, 2026, at 3:00 p.m., with anticipated award on October 1, 2026. The County standard contract template for this engagement incorporates living wage, prevailing wage where applicable, workers' compensation and professional liability insurance requirements, and HIPAA compliance if applicable.
