The city or its authorized agent must inspect the site, including all structures on the site, and certify as to its compliance. The certificate must be included with the application. The applicant must pay the city's costs for inspection. Failure to pay is grounds for denying the application.

H. Separate Conveyance.

  1. The dwelling units on the lot may not be owned or conveyed separately from each other.

  2. Condominium airspace divisions and common interest developments are not permitted within the lot.

  3. All fee interest in the lot and all the dwellings must be held equally and undivided by all individual property owners.

c. The allowed hours of construction,

d. Contact information for the project manager (for construction-related complaints),

e. Contact information for the property owner, and

f. Contact information for the community development department.

  1. This notice requirement does not confer a right on the noticed persons or on anyone else to comment on the project before permits are issued. Approval is ministerial. Under state law, the city has no discretion in approving or denying a particular project under this chapter. This notice requirement is purely to promote neighborhood awareness and expectation.

K. Deed Restriction. The owner shall record a deed restriction, acceptable to the city, that does each of the following:

  1. Expressly prohibits any rental of any dwelling on the property for a period of less than thirty days.

  2. Expressly prohibits any nonresidential use of the lot.
