1. Courtyard dwelling units on individual lots and parcels are subject to the standards of the underlying zoning district, except as follows:

2. Setbacks Abutting a Non-Courtyard Development. When a courtyard dwelling unit shares a side property line with a non-courtyard dwelling unit (including vacant lots), the courtyard dwelling unit must be set back from the common property line by a minimum of seven feet in the RS, RM-10 and RM Districts and 14 feet in the RL District.

3. Construction and Maintenance Easement. Prior to building permit approval, the applicant must submit a copy of a recorded easement for every courtyard dwelling unit that guarantees rights for the purpose of construction and maintenance of structures and yards. The easement must stipulate that no fence or other obstruction may be placed in a manner that would prevent maintenance of structures on the subject lot.

4. Privacy. In order to maintain privacy of a courtyard on an abutting courtyard lot or parcel, the windows on the first story wall must be clerestory windows located a minimum of five feet from the interior floor or obscured glass (e.g., frosted, patterned, bubbled, ribbed). This standard does not apply to abutting non-courtyard lots or parcels.
