Other people are so private they could never abide strangers trooping through their innermost sanctums. Many people don't want the bother of straightening up their homes, hiding their valuables, and cleaning up afterwards.
Others worry about damage or theft. Tour organizers post 'docents' (aka volunteer guards) throughout the homes. Rip-offs on home tours are extremely rare, organizers say.
Tour organizers generally provide liability insurance in case of injury.
Still, there are people who clamor to get their homes on tours. In San Mateo, Siguenza has several queued up for the next one. "We could put on the tour every other year if it was just based on finding enough houses," she says. "But there's much more to it."
For a tour to succeed, it has to have the right houses and the right mix. "We wanted it to be a fun event, where people would enjoy what they were seeing," Siguenza says. "We have to turn people down sometimes," referring to homeowners.
Ingrid Spencer, who chooses houses for Modern Home Tour's events nationwide, thinks of tour goers as the "audience." "You need to create a day that has some unity, that is fun and informational. You want to keep people entertained for six hours."
Putting on a home tour can be tough on both homeowners and organizers. Kaaren Sipes, who showed her home on a Highlands tour, advises people who would do the same to hire cleaners both before and after the event. "So then you're not fussing about all that."
"Think about where you don't want people to go, and have enough people in the house to answer questions," she says. "There were times we had 50 people in the house."
