This chapter shall be entitled “Building Code, Additional Requirements and Amendments.” [Ord. 1581 § 21, 2013.]

The purpose of this chapter is to set forth provisions that are supplemental to or amend the International Building Code (IBC) as adopted by DMMC 14.01.050. [Ord. 1581 § 23, 2013.]

14.05.040 Conflicts.

Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern except that the hierarchy of the codes established in RCW 19.27.031 shall govern. [Ord. 1581 § 24, 2013.]

14.05.050 Amendments adopted.

The amendments, additions, and exceptions to the International Building Code (“IBC”) are adopted and shall be applicable within the City. [Ord. 1581 § 25, 2013.]

(1) At the time of filing a building permit application, the applicant shall submit all required information together with any application form and applicable fees, for any of the following:

(a) Design review;

(b) Shoreline substantial development permit;

(c) Land clearing, grading, or filling permit;

(d) Development exceptions for environmentally critical areas;

(e) Environmental review (SEPA).

(2) No building permit application shall be accepted without the required information, completed application and applicable fees.

(3) When the Planning, Building and Public Works Director makes a determination that certain improvements including, but not limited to, curbs, gutters, sidewalks, driveways across sidewalks, piped storm drainage, retaining walls, street illumination, landscaping, slope protection, and underground utilities are required at some future date by existing ordinance(s), no building permit application shall be approved by the Building Official for any proposed project unless the building permit application is accompanied by a properly executed local improvement district (LID) covenant that has been recorded at the King County Department of Records.

(4) The filing of a complete building permit application for a proposed construction project in compliance with applicable state law, ordinances, and regulations of the City shall establish a vested right. For a building permit to be issued, the proposed project must comply with the State Environmental Policy Act. For the purpose of the IBC and the IRC, a “complete building permit application” means an application which contains all information required to be submitted by any applicable provisions of this code. [Ord. 1581 § 26, 2013.]

14.05.070 Optional method of obtaining prior approvals – Agreement regarding vested rights.

(a) The filing of an application for any of the approvals referred to in this section prior to the filing of a valid and complete application for a building permit shall not establish or create a vested right to proceed with construction of any proposed project in accordance with the ordinances and regulations existing at the time of the filing of such application, or at any time thereafter prior to the filing of a valid and complete building permit application.

(b) An applicant who elects to take advantage of the provisions of this section shall, at the time of making application for the approvals referred to in this subsection, execute an agreement with the City that the acceptance and processing of such application shall in no way establish or create a vested right to proceed with construction of any proposed project in accordance with the codes, ordinances, or regulations existing at the time of filing of such application, or at any time thereafter prior to the filing of a valid and complete building permit application.

(c) The provisions of this section do not apply to grading or filling done in preparation for the construction of a single home.

(2) An applicant who elects to take advantage of the provisions of this section may at any time elect to file a complete building permit application, notwithstanding that the approval applied for under subsection (1) of this section has not previously been obtained. [Ord. 1581 § 27, 2013.]

The Building Official is authorized to grant, in writing, one or more extensions of time, for periods not more than 180 days each. The extension shall be requested in writing and justifiable cause demonstrated.

(2) Action on Application and Time Limit of Application. Applications for which no permit is issued within 180 days following the date of application filing shall expire by limitation, and plans and other data submitted for review may thereafter be returned to the applicant or destroyed by the Building Official. The Building Official may extend the time for action by the applicant for a period not exceeding 180 days on request by the applicant showing that circumstances beyond the control of the applicant have prevented action from being taken. No application shall be extended more than once. In order to renew action on an application after expiration, the applicant shall reapply and pay a new plan review fee.

The Building Official shall extend the life of an application if any of the following conditions exist:

(a) Compliance with a declaration of significance under the State Environmental Policy Act provisions is in progress; or

(b) Any other City review is in progress, provided City staff determine that the review is proceeding to a timely final City decision; or

(c) Litigation against the City is in progress, the outcome of which may affect the validity of any permit issued pursuant to such application.

(3) Use and Occupancy. No building or structure shall be used or occupied, and no change in the existing occupancy classification of a building or structure or portion thereof shall be made until the Building Official has issued a certificate of occupancy as provided herein with the exception of Group U Occupancies.

Issuance of a certificate of occupancy shall not be construed as an approval of a violation of the provisions of this code or of other ordinances of the jurisdiction. Certificates presuming to give authority to violate or cancel the provisions of this code or other ordinances of the jurisdiction shall not be valid.

(4) Special construction – Marquee, is amended to read as follows:

A marquee is a permanent roofed structure attached to and supported by the building, providing protection from the weather elements, but does not include a projecting roof. For the purposes of this chapter, a freestanding permanent roof-like structure providing protection from the weather elements, such as a service station gas pump island, shall also be considered a marquee.

The purpose of these provisions is to authorize the construction of five-story wood frame buildings as an approved alternate design and construction method under the IBC, and to set forth the criteria and standards which must be met before a building permit may be issued for a five-story wood frame building within the zoning classifications set forth in DMMC 14.05.130.
