The Seattle City Council's proposed "Megahouse Legislation" will be debated in a public hearing on Sept. 22 and could take effect as early as November.

In response to community outcry against new, massive homes that tower over their neighbors the bill was introduced on July 28. It would modify the land use and zoning standards of single-family neighborhoods for the first time since 1982.

"The building design profession has changed dramatically since then," said Richard Conlin, Seattle City Council president. "It was necessary to take another look."

Seattle City Council member Sally Clark, who chairs the Planning, Land Use and Neighborhoods Committee, said that as development in Seattle has been proven profitable, there is a perception that Seattleites today are looking for larger homes.

Robert Drucker, a member of the Sunset Hill Community Association, claimed that there are dozens of "megahouses" in his neighborhood.

"They have an effect on the immediate neighbors," Drucker said. "They block sunlight and views and damage the scale of the neighborhood."

Conlin originally proposed the legislation in an effort to preserve the character of Seattle's neighborhoods. The City Council hopes to balance the needs of growing families while ensuring that new homes contribute positively to their neighborhood.

The new bill would limit properties' hardscape surfaces including driveways, walkways, decks or patios to help maintain open space and preserve vegetation.

A new formula has also been proposed to determine lot coverage allowance. If a lot were smaller than 5,000 square feet than the size of the home would be limited to 1,000 square feet plus 15 percent of the total lot area.

Neighbors to these large homes claim that the structures block sunlight from the rest of the neighborhood. The new legislation addresses this by removing height-averaging provisions that allow the height of a home to be based on the height of adjacent homes if it exceeds the 30-foot height limit.

Another commonly disliked aesthetic are the large garages at the forefront of many larger homes. Under the proposed legislation garage doors limited to 50 percent of the front fa
