PRELIMINARY INFORMATION |
A. Application for Permit. This is used to establish the scope of work and identify the property owner and/or agent. The name, address, and telephone number of the owner and the applicant (if different from the owner) are required on the application so the parties may be contacted if questions arise and to notify the applicant when the permit is ready for pickup. |
B. Contractor's Registration Number. Washington state law requires that contractors be licensed with the state. |
C. Property Tax Account Number. The property tax account number is an identifying number (commonly known as the "parcel number") that is assigned by the assessor's office. |
D. Complete Legal Description of Property. The legal description describes the parcel of land identified by the property tax account number (or parcel number). It should describe what is known as a "legal lot" and should be identical to the parcel as found on the assessor's maps and the required plot plans. It is acceptable to submit a legal description of the parcel as it appears on deeds, real estate contracts, and statutory warranty deeds, or on information at the assessor's office. |
The legal description is used to check the dimensions of a parcel, the uses allowed by the current zoning requirements, and any underlying restrictions (such as setbacks from property lines or from easements, lot coverage, or building heights). The legal description is also used to check for sensitive areas and other planning controls. (See Building Plans.) |
Note: For projects that have multiple parcels, list each parcel number with its corresponding legal description. |
