Yes and no. The new code proposes both lot coverage and a total Impervious Surface Ratio (ISR). As mentioned with the ADUs, one of the goals of the new plan is to encourage existing homes to stay. Part of the reason older homes are torn down and new ones built is because the lots are valuable, and more often than not, variances were approved to allow for bigger houses. However, a lot of variances were also approved to just allow existing homeowners to add amenities to their back yard, like pools, patios, outdoor or summer kitchens. Under the new proposal, there would still be 35% lot coverage. \That 35% would only include the house and required driveway. The remaining 15% (what’s left over from 50% minus the 35% for the house and garage) will now be called ISR. The ISR can only be used for accessory uses, like patios, pool decks, sheds, etc. That 15% could not be used to make the house bigger.
