RR Rural Residential - For a single-family or two-family dwelling the two side yards must total 100 ft, so a house cannot simply sit 30 ft from each side line. A corner lot also has a 60 ft corner side setback, separate from the front, side and rear.

• The 25% total coverage counts buildings and paving together, which leaves little room for paving beyond the 20% building footprint.
• A townhouse or apartment building is held to the 30 ft single-side figure alone.

SR Suburban Residential - A corner lot has a 25 ft corner side setback, separate from the front, side and rear. The 40% total coverage counts buildings and paving together, against 28% for the building footprint alone.

• The 30 ft combined side yard applies to single-family and two-family dwellings only; a townhouse or apartment building is held to the 15 ft single side alone.

UR-1 Urban Residential 1 - The front setback is 30 ft or as set by the contextual front-setback rule of § 240-3.3B, and on a built-up block that section, not the 30 ft figure, sets the building line. A corner lot has a 25 ft corner side setback.

• Where the principal building is within 20 ft of the side lot lines, the first floor elevation may be at most 4 feet.

• The 50% total coverage counts buildings and paving together; the building footprint alone is capped at 28%.

• A corner lot has a 10 ft corner side setback, separate from the front, side and rear.

• A duplex needs 6,000 sq ft on 80 ft at that rate, and an eight-unit building 24,000 sq ft, which on 80 ft of frontage is a lot 300 ft deep, so frontage usually binds before the rate.
• Minimum lot width is 60 ft for single-family and single-family-attached dwellings, and 80 ft for two-family, townhouse and multifamily alike.
• For a single-family or two-family dwelling the side yards must total 12 ft; a townhouse or apartment building is held to the 5 ft single side alone.
