On Thursday — Walt Disney's birthday — the owners will join the alderman, a grandson of Roy Disney and their team of preservationists at the house to launch a Kickstarter campaign to raise $500,000 for renovations. Prizes for donors will range from getting their name inscribed in a leather-bound book that will remain in the house to a one-night stay — for a donation of $10,000. The owners bought the house for $173,000 and at this point have not filed for nonprofit status.
