(C) All utilities must be underground.

(2) Between resulting lots. Separate conveyance of the resulting lots is permitted. If dwellings or other structures (such as garages) on different lots are adjacent or attached to each other, the urban lot split boundary may separate them for conveyance purposes if the structures meet building code safety standards and are sufficient to allow separate conveyance. If any attached structures span or will span the new lot line, the owner must record appropriate CC&Rs, easements, or other documentation that is necessary to allocate rights and responsibility between the owners of the two (2) lots.
(l) Regulation of uses.
(1) Residential-only. No non-residential use is permitted on any lot created by urban lot split.

(3) Owner occupancy. The applicant for an urban lot split must sign an affidavit stating that the applicant intends to occupy one (1) of the dwelling units on one (1) of the resulting lots as the applicant's principal residence for a minimum of three (3) years after the urban lot split is approved.
(m) Notice of construction.
(1) At least thirty (30) business days before starting any construction of a structure on a lot created by an urban lot split, the property owner must give written notice to all the owners of record of each of the adjacent residential parcels, which notice must include the following information:
(A) Notice that construction has been authorized;
(B) The anticipated start and end dates for construction;
(C) The hours of construction;
(D) Contact information for the project manager (for construction-related complaints); and
(E) Contact information for the Building & Safety Department.
(2) This notice requirement does not confer a right on the noticed persons or on anyone else to comment on the project before permits are issued. Approval is ministerial. Under state law, the City has no discretion in approving or denying a particular project under this section. This notice requirement is purely to promote neighborhood awareness and expectation.
(n) Deed restriction. The owner must record a deed restriction on each lot that results from the urban lot split, on a form approved by the city, that does each of the following:
(1) Expressly prohibits any rental of any dwelling on the property for a period of less than thirty (30) days.
(2) Expressly prohibits any non-residential use of the lots created by the urban lot split.
(3) Expressly prohibits any separate conveyance of a primary dwelling on the property, any separate fee interest, and any common interest development within the lot.
(4) Expressly requires that any net new unit created as a result of the provisions of this division be deed restricted for affordable housing at the following levels:
(A) Rental products shall be made affordable to very low or low income households.
(B) For-sale products shall be made affordable to moderate income households.
(5) States that:
(A) The lot is formed by an urban lot split and is therefore subject to the city's urban lot-split regulations, including all applicable limits on dwelling size and development.
(B) Development on the lot is limited to development of residential units under Divisions 2 and 3 of this article, except as required by State law.

Sec. 41-2110. - Specific adverse impacts.¶
(a) Notwithstanding anything else in this section, the city may deny an application for an urban lot split if the building official makes a written finding, based on a preponderance of the evidence, that the project would have a "specific, adverse impact" on either public health and safety or on the physical environment and for which there is no feasible method to satisfactorily mitigate or avoid the specific adverse impact.
(b) "Specific adverse impact" has the same meaning as in Gov. Code section 65589.5(d)(2): "a significant, quantifiable, direct, and unavoidable impact, based on objective, identified written public health or safety standards, policies, or conditions as they existed on the date the application was deemed complete" and does not include (1) inconsistency with the zoning ordinance or general plan land use designation or (2) the eligibility to claim a welfare exemption under Revenue and Taxation Code section 214(g).
(c) The building official may consult with and be assisted by planning staff and others as necessary in making a finding of specific, adverse impact.
