Summary
In Plano's SF-A, Single-Family Residence Attached district, Zoning Ordinance § 9.1000.3 caps multi-unit platted lots at 10 dwelling units per acre. Section 9.1000.4 lets the Planning & Zoning Commission raise that ceiling to 12 units per acre if it finds the increase necessary to secure additional amenities such as open space, landscaping, screening, subdivision design or protection of the natural environment.
Minimum Lot Area per Dwelling Unit 2,250 square feet when on individually-platted lots. Maximum of 10 units/acre when multiple units are platted on a single lot, except as provided in Sec. 9.1000.4. ... When multiple units are platted on a single lot, the density may be increased to 12 dwelling units per acre if the Planning & Zoning Commission determines that the increase is necessary to provide additional amenities.

Full Breakdown
3 area table sets a baseline of 2,250 square feet of lot area per dwelling unit when units are individually platted, and states that where "multiple units are platted on a single lot," density is capped at a maximum of 10 units per acre, "except as provided in Sec. " The bonus is therefore discretionary rather than by-right, a developer must make the amenity case to the Commission to unlock the extra two units per acre, and absent that finding the 10-unit-per-acre ceiling controls. 4 subsection also permits a front yard reduced to 10 feet where the driveway and garage are alley-accessed, the garage door sits 20 feet off the rear property line, and the buildable area gained is offset by increased rear or side open yard, a separate accommodation from the density bonus but part of the same subsection package that trades design flexibility for defined performance conditions.
Violations & Fines
Development that exceeds the 10-unit-per-acre SF-A baseline without an affirmative Planning & Zoning Commission finding under § 9.1000.4 violates the zoning ordinance and triggers § 1.700's general penalty: a fine under Code of Ordinances § 1-4(a) of up to $2,000 per offense (escalating to $500-$2,000 and $1,000-$2,000 minimums for repeat convictions within 48 months), with each day of the violation treated as a separate offense.
