Chapter 2.53 — FEES FOR NEW DEVELOPMENT
San Mateo County Municipal Code · 2026-09 edition · updated 2026-09-27 · San Mateo County
2.53.010 - Findings—Background.¶
The Board of Supervisors has determined that:
(a)
New development in the unincorporated area of San Mateo County adds incrementally to the burden on existing County public roads and drainage systems.
(b)
There is a need to finance a Countywide program to reconstruct existing public roads which have suffered deterioration to the extent that operational aspects of the road are in danger of becoming impaired, to upgrade existing public roads to meet the additional burden caused by increased development and to establish a mechanism to finance drainage facility improvements in easements that are reaching the end of their serviceable life.
(Ord. 4324, 08/15/06)
2.53.020 - Findings—Purpose and use of fee.¶
The Board of Supervisors has further determined that there is a reasonable relationship between the roadway and drainage facilities and improvements which will be financed with fees collected, and the development projects upon which the fees will be imposed, in that additional development will lead to an increased use of the road and drainage facilities with the consequential additional burden on the road and drainage facilities. Accordingly, the following fees and charges are established.
(Ord. 4324, 08/15/06)
2.53.030 - Amount and standards for fees.¶
Except as otherwise provided herein, fees shall be imposed on all building permits and subdivision applications for new residential, commercial, and industrial development in the following amounts:
Type of Development Fee
Residential $1.25 per square foot of assessable space
Industrial $1.25 per square foot of assessable space
Commercial-Self-Storage $0.08 per square foot of assessable space
Commercial-Lodging $1.25 per square foot of assessable space
Commercial-Retail $2.50 per square foot of assessable space
Commercial-Office $2.50 per square foot of assessable space
The fee represents the portion of the approximate cost of reconstructing the travel surface of the County's public road system and the drainage facilities which is attributable to the proposed development.
(Ord. 4324, 08/15/06)
2.53.040 - Fee charged for reconstruction or remodeling.¶
A fee in the amount specified in section 2.53.030 of this chapter, shall also be charged for building permits for any reconstruction or remodeling of existing residential, commercial, or industrial structures. The fee will be charged only on the increase in assessable space resulting from the reconstruction or remodeling.
(Ord. 4324, 08/15/06)
2.53.050 - Determination of areas of benefit.¶
The Director of Public Works shall identify and establish areas of benefit for the unincorporated area of the County based on development and traffic patterns. An area of benefit shall be identified for each area where it can be determined that the roads within the area are predominantly used by development located within the area.
(Ord. 4324, 08/15/06)
2.53.060 - Establishment of road improvement fund.¶
There is created in the Office of the County Auditor/Controller and the County Treasurer a special interest- bearing fund entitled "San Mateo Countywide Roadway Improvement Fund." All amounts collected for roadway development fees under this chapter shall be deposited in the fund.
(Ord. 4324, 08/15/06)
2.53.070 - Limitations on use of fee.¶
(a)
Fees collected from development in an established area of benefit may only be used to reconstruct public roads and drainage facilities lying within the same area.
(b)
Fees may be used only for reconstruction of roads and drainage facilities, and not for routine or periodic maintenance. For purposes of this chapter, reconstruction must, at a minimum, meet the standards for road construction as set forth in the "Guidelines, Relating to Gas Tax Expenditures on Streets and Roads," as published by the Office of the State Controller, as such guidelines may be amended from time to time. Reconstruction of drainage facilities should be limited to reconstructing those facilities that were built at the time of subdivision development or subsequent assessment district procedures, and which are located in dedicated easements.
(c)
As used in this chapter, "reconstruction" includes, but is not limited to planning, design, and environmental review of reconstruction projects for existing roads and drainage facilities, and repaving of existing roads.
(Ord. 4324, 08/15/06)
(Ord. No. 04461, § 1, 2-10-2009)
2.53.080 - Adjustment of fee.¶
(a)
On January 1st of each year beginning in 2001, the development fees imposed by this chapter shall be adjusted by a percentage amount equivalent to the percentage change in the Engineering News Record Construction Cost Index for the preceding twelve (12) month period.
(b)
The amount of fee applicable to any permit shall be computed based on the fee in effect as of the date of approval of the building permit or tentative subdivision map. The Board of Supervisors shall review the adequacy of the development fees established herein at least once every five (5) years or, if it deems appropriate, more often than once every five (5) years.
(c)
The Department of Public Works shall provide an annual report to the Board of Supervisors which specifies any change in the fee due to automatic annual adjustments, the status of trust funds established to fund the cost of mitigating traffic impacts associated with new development, and the status of any improvement projects financed in full or in part by funds collected.
(Ord. 4324, 08/15/06)
2.53.090 - Improvements in lieu of fee.¶
Applicants for building permits and subdivision approvals required to pay fees under this chapter may, as an alternative to paying the fee, offer to construct road improvements determined by the Director of Public Works to be appropriate for the type of development being proposed. In making such determination, the Public Works Director shall take into consideration the extent to which the proposed improvements would be consistent with the existing road improvements in the immediate vicinity, and the extent to which the road improvements would either improve or impair the operational characteristics of the public road if installed immediately. In exchange for such offer, the applicant shall receive a partial or full offset of the fee which would otherwise be required.
(Ord. 4324, 08/15/06)
2.53.100 - Additional road improvement requirements—Commercial and industrial development.¶
(a)
The establishment of the fee prescribed in this chapter shall not relieve an applicant for a building permit or subdivision approval from the requirement to make such other road drainage facility improvements as are provided by County regulations, as they may be amended from time to time, including the requirement to improve private roads serving a parcel, and the requirement to improve all roads, public or private, lying within the limits of a subdivision.
(b)
Commercial and industrial development shall remain subject to the requirement to construct such public street improvements as are required by County regulations, as they may be amended from time to time.
