The San Mateo County Assessor’s Office is located in Redwood City, California. It serves the residents, especially the property owners, of San Mateo County. Among its duties is valuation of residential, commercial, industrial and special purpose properties for property tax assessment purposes. The valuation and appraisal of properties may be achieved using one or more of the three approaches to value, i.e., Sales, Income, and Cost approach. Property owners sometimes disagree with the re-assessed value of their property and occasionally the disagreement results in a formal appeal filed with the County Assessment Appeals Board. To value, appraise, and reassess properties upon change in ownership, new construction, or market decline, the Assessor's office contracts with providers of sales and property data, lease data, as well as cost data for the properties located in San Mateo County and the neighboring counties. This solicitation is to obtain unlimited access to digital construction cost data through an online interface ((hereinafter referred to as "construction cost database") for our residential and commercial appraisal staff to assist with mass appraisal valuations of residential and commercial properties in San Mateo County using Cost approach to value only. Until now, the San Mateo County Assessor's office has been using a vendor that has met its needs for market construction cost data for the cost approach to value. However, moving forward, the selection of a provider for a construction cost database will be conducted through a competitive solicitation process to ensure best construction cost database can be obtained at the best value. Therefore, to carry out its constitutional mandate, the Assessor's office invites all vendors with a proven track record and ability to provide a comprehensive, defensible, and scalable residential, commercial, and industrial construction cost database to submit their proposals. At the conclusion of this procurement process, the Assessor’s Office will select a construction cost database that meets the specified requirements and provides the best value. The selected construction cost database will support the cost approach to value for mass appraisal of the county’s diverse property base.
