It appears there is some potentially costly damage such as apartments with cracked foundations. Apparently Fullerton felt the quake more according to this report:
Fullerton Mayor Pro Tem Greg Sebourn was at home sitting on the couch getting his 4- and 8-year-old daughters ready for bed when the earthquake hit Friday night.
“It started shaking and my youngest daughter jumped in my lap and started screaming,” he said. “We started walking toward the door when a second jolt knocked me and my daughter down.”
...“It’s the strongest jolt I’ve ever felt, and I’ve been in the same town for 41 years,” he said.
Then there was this story:
A prototype earthquake early-warning system worked again Friday night, giving seismologists in Pasadena about a four-second heads-up before shaking was felt from the magnitude 5.1 quake that struck near La Habra.
The system is being tested by a team of scientists on a U.S. Geological Survey project to create a statewide network.
USGS seismologist Lucy Jones has said the system works because while earthquakes travel at the speed of sound, sensors that initially detect the shaking near the epicenter of a quake can send a message faster -- at the speed of light -- to warn residents farther away that the quake is coming.
Somehow a four-second warning doesn't seem like much. But I guess it would be better than nothing.
And now they're talking about the incident as an earthquake swarm. The OC Breeze had a story and a map:

The wide white line on the right is the 57 Freeway.
The wide white line at the bottom is the 91 Freeway.
The diagonal line in the lower left corner is Interstate 5.
The swooping white line at the top is the 60 Freeway.
I've always tried to visualize being "swarmed" by earthquakes.
