If the permittee fails to call for final inspection within thirty (30) days after gunite inspection has been made, a final inspection may be made by the Building Division of the Community Development Department, and notice thereupon given on the property regarding any corrections required. If the Division has not been notified that the corrections have been made and requested to reinspect within a reasonable length of time, the permittee will be subject to the reinspection fee set forth in Section 109 of this Code.
The swimming pool deck and all portions of the lot shall drain to the street or to an area approved by the Building Official. When a pool deck extends to within three (3') feet of an adjacent property, means shall be provided to conduct splash water to a satisfactory point of disposal.
6207 Fencing, Gates and Locks.
6207.1 Required. The City Council, after due consideration, hereby finds and determines that the maintenance of a swimming pool without appropriate precautionary measures constitutes a hazard to the safety of small children within the City.
6207.2 Required gates, fencing, and closing, latching or locking devices shall be installed prior to plastering of the pool.
6207.3 Specifications. Any person, firm or corporation in possession of land within the City, either as owner in fee, purchaser under contract lessee, tenant, licensee, or any type of legal estate, upon which is situated a swimming pool, as defined in Section 6202, shall at all times maintain on the lot or property, upon which such pool or such body of water is located within a fence or wall five (5') feet minimum in height completely surrounding such pool or body of water. Lakes and other bodies of water not designed or used for swimming or immersion purposes, shall be separated from the swimming pool by a fence or wall conforming to this section.
Such fence or wall shall have no opening therein or space between the intermediate members greater than four (4") inches maximum, including doors or gates.
No such fence or wall shall provide ladder-like access to the swimming pool area. Dwelling units of R-1 and R-3 occupancies may be used, as well as buildings or structures accessory thereto, as a part of such enclosure.
The top of the fence, as measured from outside, shall be located five (5') feet minimum clear, measured in an arc from the top of the fence, from any surface or slope.
Each gate or door opening through a pool enclosure shall open outward away from the pool and shall be equipped with a self-closing and self-latching device capable of keeping the gate or door securely closed at all times when not in use.

Required latching devices shall be installed four (4') feet, six (6") inches minimum above adjacent ground level.
Equipment Gates. Equipment gates, for the purpose of this section, shall be two (2) gates, installed in such a manner that, when closed, each shall abut the other and form an integral part of the fence. Such gates shall not be used for normal access. With the exception of those infrequent times when the gates may be open to permit access for repair or replacement of equipment and the like, the gates shall be bolted top and bottom or closely locked together. Equipment gates however, may be used for access gates when one gate is installed in a semipermanent manner and cannot be readily opened without removing bolts, screws, or those certain things requiring tools to remove that make the same semipermanent and the opposing gate is installed in the manner hereinabove specified.
6207.4 Modifications. The Building Official may permit other protective measures or devices to be used or may grant modifications and accept alternatives to the fencing requirements in individual cases with respect to the height, nature, or location of the fence, wall, gate or latches, or the necessity therefore, provided the degree of protection is not reduced thereby.
6207.5 Exceptions. Natural or man-made lakes, marinas or reservoirs used primarily for water conservation, irrigation or recreation shall not be deemed to be a swimming pool or body of water requiring fencing by this section.
6207.6 Safeguards Prerequisites to Filling. No water shall be placed in any swimming pool prior to the installation of all safeguards specified by this chapter.
6207.6.1 If exit alarm, per California Building Code, Section 322.214.171.124 is installed on door(s) with direct access to the pool, the alarm will be capable of providing a sound pressure of 85 dBA minimum when measured indoors at ten (10') feet from the alarm.
