The solution comes from arts organization Fractured Atlas, who has set up the software for use by the diverse set of artists they regularly work with.
Use of the database is free to users, and, in fact, it's also free to list your business as a space. Premium features for the spaces, like syncing availability calendars to the site, help Fractured Atlas pay for the costs of maintaining the site. Businesses (bars, restaurants, etc.) looking to rent their space to film crews can do so at no cost to them.
Artists can easily search by rental price, and spaces can set their own prices. Filmmakers can look for special equipment and opportunities. Photo studios like ACME studios, for instance, have plenty of props and various lighting opportunities. Filmmakers who worry about sound can (and should) always check with the space first to see if there might be any issue with noises creeping in, but the Spaces Program Director Lisa Niedermeyer suggests that filmmakers take a look at spaces that are open to allowing percussion or loud music rehearsals because those spaces tend to be soundproofed well. The calendar syncing, utilized by many spaces whose businesses is rentals, can help filmmakers browse for availability and compare sites in a last minute situation.
The software interface powering Spaces is being deployed by organizations in a total of ten markets: Atlanta; Austin; Chicago; Los Angeles; the state of Minnesota; New York City; Philadelphia; Sacramento; the San Francisco Bay area; and Washington, DC. While Fractured Atlas manages the New York City database, regional organizations manage the other sites.
