Full Breakdown
607, titled "Building site coverage," sets the standard for the Low Density Residential (R-1) district: not more than 70% of the total lot area may be devoted to main and accessory building areas, parking areas, driveways and patios, and the remaining 30% must be devoted to landscaping, lawns and outdoor recreational facilities, with swimming pools specifically named as an example of that reserved open space. 807, so a homeowner or builder faces the same coverage ceiling regardless of which standard residential zone the parcel sits in.
The provision counts driveways and patios toward the impervious side of the ledger along with the building footprint and parking areas, which means hardscape improvements outside the house itself, not just the structure, count against the 70 percent cap. 807's neighboring setback sections.
Violations & Fines
Exceeding the 70 percent lot coverage cap is a zoning violation of Section 9-3.607 (or its R-2/R-3 equivalents). Under the general penalty provision, Section 1-2.01, that is a misdemeanor punishable by up to a $500 fine and six months in jail, or an infraction with escalating fines of $50, $100 and $250 for repeat convictions within a year, with each day the condition continues treated as a separate offense.
