  1. Application. An application for a temporary trailer permit shall be filed with the Building Official on forms prescribed by the Building Official, along with any plans or additional information required and a fee as established by a resolution of the Town Council. The application shall include, in part, evidence supporting the requirements of this section and all applicable state statutes.

  2. Review and Approval Authority. The Building Official shall review and approve, conditionally approve, or deny a temporary trailer application administratively with no public meeting.

(c) Criteria for Permit. A temporary trailer permit shall be issued if the structure complies with all of the following criteria. The Building Official shall have the authority to impose other reasonable conditions and restrictions on the permit in order to protect the peace, health, safety and general welfare of any person or persons or of the general public. Additional conditions may include the provision of off street parking and increased setbacks.

  1. The property is owned and occupied as the owner's principal residence.

  2. The proposed location for the trailer complies with applicable provisions of the San Anselmo Zoning Code, including setbacks. However, if the property owner adjacent to the side or rear setback where the trailer will be located has consented in writing to the installation of the trailer in the setback, an exception will be made to the setback requirements. This subsection may be waived in the event of a disaster to permit a trailer in a front, rear or side setback.

  3. No other habitable units exist at the site.

  4. A building permit has been issued and is in full force and effect on the same site, or on adjacent lots under the same ownership, for construction or remodeling that will render the residence substandard under the Uniform Housing Code, 1997 Edition, published by the International Conference of Building Officials, as amended from time to time. If the permit request is associated with a residence that has been made substandard by disaster, the Building Official may issue the permit after the disaster and prior to issuance of a building permit.

  7. The trailer must have built-in toilet facilities or on site access to toilet facilities.

  8. Any plumbing facilities shall be connected to a sewage disposal system approved by the Ross Valley Sanitary District for the structure under construction and approved by the Building Department. In the event of a disaster that precludes connection to the sanitary sewer system, the Building Official may approve equivalent facilities.

  9. If the site is in a Special Flood Hazard Area identified on the Town Flood Insurance Rate Map, the Town Floodplain Administrator has verified in writing that the trailer placement will comply with applicable requirements for a development permit under Title 7 Chapter 11, Protection of Flood Hazard Areas.

  10. The temporary use shall not involve mechanical equipment that generates noise, such as a generator, unless the operation of the equipment will comply with any applicable noise regulations.

  11. The use shall comply with any applicable Fire Code Standards, including access, fire suppression, setbacks and addressing.

  12. The trailer will not be located where there would be any undue hazard to the safety or health of the inhabitants of the trailer, or where the parking and maintenance of the trailer would constitute a hazard or detriment to the peace, health, safety or welfare of other persons in the vicinity or of the general public.

  13. The applicant has submitted a financial security to cover the removal expense and has granted the Town the right to remove the trailer and to store it at the sole cost and expense of the applicant upon expiration or revocation of the permit.

(d) Expiration and Extension.

  1. The property owner shall cease using the trailer as a dwelling unit, disconnect it from the water supply and sewage disposal system, and remove it from the site within thirty (30) days after one (1) of the following events, whichever occurs first: (1) The building permit has expired; (2) Clearance for occupancy is issued by the Building Official for the primary residence; (3) Final inspection clearance on the building permit; or, (4) Twelve (12) months have passed since temporary trailer permit approval.

The Building Official may approve up to two (2) six-month time extensions if the permittee remains in compliance with the original approval and the owner is making substantial progress toward completion of the primary structure. An application for renewal shall be accompanied by a fee in an amount established by resolution of the Town Council.
