Section 30610.1.

(a) Prior to certification of the applicable local coastal program, no coastal development permit shall be required for the construction of a single-family residence on any vacant lot meeting the criteria set forth in subdivision (c) and located in a specified area designated by the commission pursuant to subdivision (b).

(b) Within 60 days from the effective date of this section, the commission shall designate specific areas in the coastal zone where the construction of a single-family residence on a vacant lot meeting the criteria set forth in subdivision (c) shall not require a coastal development permit. Areas shall be designated for the exclusion provided for in this section if construction of single-family residences within the area to be designated has no potential, either individually or cumulatively, for significant adverse impacts on highly scenic resources of public importance, on environmentally sensitive areas, on prime agricultural land or on agricultural lands currently in production, or on public access to or along the coast.

In addition, if septic tanks will be required or used, an area identified as having septic tank problems by the appropriate regional water quality control board or the State Water Resources Control Board in an approved basin plan or by other formal action of such board may not be designated for exclusion pursuant to this section.

(c) Within areas designated pursuant to subdivision (b), no coastal development permit shall be required for the construction of a single-family residence on any vacant lot which meets all of the following criteria:

(1) Is not located between the first public road and the sea or immediately adjacent to the inland extent of any beach or of the mean high tide line where there is no beach.

(2) Is a legal lot as of the effective date of this section and conforms with the minimum lot size and lot use designations of the applicable general plan and zoning ordinances.

(3) Is not located within an area known to the affected local government, or designated by any other public agency, as a geologic hazard area or as a flood hazard area, or, if located within such an area, it has been determined by the affected local government to be a safe site for the construction of a single-family residence.

(4) Is no more than 250 feet from an existing improved road adequate for use throughout the year.

(5) Can be served by an adequate water supply that is legally available for use either by means of a well or by means of a connection to a water system with sufficient capacity to serve such lot or lots; provided, that no such connection shall require the extension of an existing water main which would have the capacity of serving four or more additional single-family residential structures.

(d) The commission shall, within 120 days from the effective date of this section, specify uniform criteria that shall be used to determine the location of "the first public road" and the inland extent of any beach for purposes of paragraph (1) of subdivision (c).

(e) Within 30 days after the 120-day period specified in subdivision (b), the commission shall report to the Legislature and the Governor what has been done to carry out the provisions of this section.

(f) The provisions of this section shall apply notwithstanding any other provision of this division to the contrary.
