Thanks for your comments. I start with some screengrabs of places that look possible to identify, and then spend ages on Google, Google Maps, Google Earth, Bing Maps and Historic Aerials. Sometimes an appearance in another show can help too, as is the case with today's location. Y'all may have seen the pictures of the Duke Farm's appearance in 'Murder, She Wrote' that I posted a few weeks back. Well, it turned out that an episode a few days later led me to another Dukes filming location. I originally only watched 'The Bottom Line Is Murder' because of the guest stars: Adrienne Barbeau (Marcie in 'The Cannonball Run'), Judith Chapman (Kay Faulkner in 'The Fall Guy'), George Takei (Sulu in 'Star Trek'), and from Dukes, Pat Klous (T.C. Rogers in 'People's Choice'). Then I realized that the TV station (supposedly in Denver) was the same building as the one used as the Capitol City Hospital in 'The Boar's Nest Bears'. It was all there: low, flat-roofed white building with a distinctive wall either side of a shallow set of steps, and it even had a red curb. Unlike Dukes, 'Murder, She Wrote' also showed several other useful views. The second here shows a continuation of the wall and some previously unseen white/brick buildings behind. The third picture is a long view showing a taller building behind, and the last is a shot of the car park showing the end of the building behind the guard in the second (this building can be seen briefly in Dukes when Sheriff Little drives away, but it's quite blurry). This gave me a lot more to work with, and I knew I was looking for a larger complex, probably in the Santa Clarita area. There were far fewer buildings of this type when Dukes was filmed, so that narrowed down my search considerably. After ruling out the 'Henry Mayo Newhall Memorial Hospital' and the 'College of the Canyons', I found what I was looking for at the 'California Institute of the Arts' (or CalArts as it's usually known). Here's a picture I found taken from almost the same angle as the second one above. In the middle you can see the 'Roy G. Disney Music Hall' (the school was founded and created by Walt Disney in the early 1960s). It turns out that the building seen in Dukes has been used in several other productions too. Here it is in the 1979 movie 'The China Syndrome' starring Jane Fonda, Jack Lemmon and Michael Douglas. This is the nearest shot I could find of how it looks today (explore the campus for yourselves on Google Maps). CalArts alumni include actor David Hasselhoff, director Tim Burton, and Pixar chief creative officer John Lasseter. Many other Pixar staff also went to CalArts, and insert a secret "A113" into their movies as a reference to the classroom number used by graphic design and character animation students at the school.
