(1) Lot Standards.

(a) In determining lot area in a residential zone, the area within a public or private street or alley shall be excluded.

(b) Solar standards may impose a more restrictive lot standard. (See EC 9.2790 Solar Lot Standards.)

(c) Lot area, frontage, and width minimums may be modified with an approved cluster subdivision in R-1 or Planned Unit Development (PUD) in any zone.

(2) Small Lots. Lots shall comply with other small lot provisions unless approved as a cluster subdivision or a Planned Unit Development (PUD). (See EC 9.2770 Small Lot Standards for R-2, R-3 and R-4 Zones.)

(3) Rowhouse Lots.

(a) In R-1, rowhouse lots can be created only in a subdivision created after August 1, 2001 that contains 10 or more lots and where the overall residential density in the subdivision complies with Table 9.2750 Residential Zone Development Standards, except that the creation of new rowhouse lots is prohibited within the city-recognized boundaries of Amazon Neighbors, Fairmount Neighbors and South University Neighborhood Association.

(b) In all zones, rowhouses shall have street frontage for the residence and alley access for off-street parking.

(4) Flag Lots.

(a) No variances to residential flag lot standards are allowed.

(c) Other residential flag lot standards also apply. (See EC 9.2775 Residential Flag Lot Standards for R-1, R-2, R-3 and R-4.)

(5) Exceptions to the maximum lot size shall be granted if any of the following is met:

(a) Existing physical circumstances such as topographically constrained lands, conservation easements, existing buildings, or utility easements prevent the ability to further divide the lot.

(b) The lot exceeding the maximum lot size is intended to reserve a large lot for future land division with feasibility demonstrated by a conceptual buildout plan.

(c) The subdivision achieves a minimum density of 9 units per net acre.

(d) The exception will enable protection of natural resources.

(6) Unless approved through a planned unit development process, in any 1 subdivision there shall be a maximum of 25% duplex lots, 15% triplex lots, and 10% fourplex lots. At least 50% of the lots must be for one-family detached dwellings or rowhouses. Fractions are reduced to the next lowest number.

(7) In R-1, interior lots shall not have frontage on two non-intersecting streets unless approved through the cluster subdivision or planned unit development process where alternative proposals were evaluated, and there is no feasible alternative to the creation of double frontage lots.

(8) Duplex Division Lots. Duplex division lots shall comply with other duplex division provisions. (See EC 9.2777 Duplex Division Lot Standards.)

(9) Lot width and lot frontage minimums in R-2, R-3 and R-4 can be reduced to 20 feet as part of an approved site review plan, planned unit development, or cluster subdivision. Unless otherwise approved through a planned unit development or cluster subdivision, at no point, for the entire extent of the lot, shall the side lot lines be less than 20 feet apart.

(10) Alley Access Only Lots/Parcels can be created only through an approved cluster subdivision in the R-1 zone or an approved planned unit development in any zone.
