Subject to the granting of a conditional use permit, any substandard lot may be used as a building site, provided that all other regulations of the applicable zoning district shall apply. Substandard lots are defined below.

For the purpose of determining minimum lot size and the number of units to be constructed on a particular building site, the planning commission shall have the discretion to include or exclude any portion of such building site occupied by any easement, depending upon the extent to which it impairs the use of the property.

No parcel of land, not part of a recorded subdivision shall be developed or improved and no building permit shall be issued for the erection of any structure thereon until a use permit therefor has been issued by the planning commission. When approving such use permit, the commission may require such improvements, dedications or conditions as may be required by the city subdivision ordinance (Title 15), as well as any other conditions deemed necessary to achieve the purposes of this title.
