1. All blocks must be concrete.

2. A pier may be made of a single stack of eight-inch by eight-inch by 16-inch blocks if the blocks are not stacked more than three blocks high. A pier made of a single stack of blocks shall be installed at a right angle to the main frame longitudinal member and shall be capped with no more than two two-inch by eight-inch by 16-inch wood blocks or one four-inch by eight-inch by 16-inch concrete block.

A shim shall be at least four inches wide and six inches long. The installer shall fit the shim properly and drive it tight between the wood plate or pier and the main frame to ensure that the manufactured home is level and properly supported at all load-bearing points. A block that abuts a wedge-shaped shim shall be solid.

H. Anchoring Systems. All mobile or manufactured home(s) shall require anchoring systems that meet with the manufacturer specifications as provided in this title and ZMC Title 17.

(Ord. 1289 § 1 (Exh. A), 2011; Ord. 1227 § 3 (Att. C), 2010; Ord. 1213 §§ 28 – 30, 2009; Ord. 1202 § 2 (Exh. A), 2009. Formerly 17.88.090)

15.20.100 Roofing construction.

The city council for the city has determined that the requirements of the International Building Code, which are in effect and have been adopted by the city, do not adequately address safeguards for work on the roof of structures within the city. The city council has therefore determined that a permit should be required prior to the placement or replacement of a new roof on structures so as to ensure that the roofing work is done in a satisfactory and safe manner for the protection of all residents and property within the city.

A. Permit Requirements. All persons desiring to replace an existing roof or construct a new roof over an existing roof on any structure within the city shall be required to obtain a building permit from the city prior to the commencement and completion of the work. The cost of the permit, and the manner of application for said permit, shall be in accordance with the applicable provisions of the International Building Code which is in effect within the city; provided, however, that a separate permit for roofing work shall not be required where a building permit is applied for and obtained for the construction of a new residence or the remodeling or rebuilding of an existing residence when the building permit obtained includes the roofing work. (Ord. 1289 § 1 (Exh. A), 2011; Ord. 1202 § 2 (Exh. A), 2009. Formerly 17.88.100)

15.20.110 Temporary water meters.

It is customary in the city of Zillah, Washington, that when a contractor obtains a building permit, the contractor is provided with a water meter monitoring a temporary supply of water on the construction site which generally comes from fire hydrants. Recently, some contractors have not returned the borrowed water meter or it has been returned in a damaged state. Accordingly, a deposit shall be required from the contractor/builder which will only be refunded upon the return of the temporary water meter in the same operational condition previous to its use.

A. Requirement of Security Deposit. After the issuance of a building permit, a contractor/builder may request the use of a water meter on a temporary basis to monitor water flow from a temporary water source to the construction site. The contractor/builder shall be required to post a cash deposit in accordance with the city fee schedule in order to use the water meter and obtain a temporary source of water. Said cash deposit will be refunded upon (1) the return of the water meter in the same condition as existed, prior to its use by the builder/contractor; and (2) payment of all charges for water/sewer use incurred by the builder/contractor from the temporary source. In the event that the meter is not returned in satisfactory condition or charges/fees paid in full, city may apply such deposit to cost of replacement or repair of the meter or payment of delinquent charges/fees. (Ord. 1289 § 1 (Exh. A), 2011; Ord. 1202 § 2 (Exh. A), 2009. Formerly 17.88.110)

15.20.120 Model homes.

The city council has determined that it is appropriate to establish standards and guidelines for model homes. As many as four model homes may be constructed within a subdivision which has received preliminary plat approval. The purpose of model homes shall be to demonstrate a variety of housing designs together with all associated on-site improvements, e.g., landscaping, improved driveways, and patios. Model homes shall be established subject to the following criteria:

A. Model homes shall meet all applicable codes of the city of Zillah.

B. Only one model home may be occupied as a temporary real estate office.

C. Access and fire safety provisions shall be provided in a manner approved by the building official prior to construction of a model home. A model home may not be occupied as a dwelling unit or sold until the plat is recorded.

D. The building official may grant a variance to utility connection for any unoccupied model homes where it is determined not to affect public health, safety, or welfare. (Ord. 1289 § 1 (Exh. A), 2011; Ord. 1202 § 2 (Exh. A), 2009. Formerly 17.88.120)
