Have you been on craigslist yet? I know a lot of landlords will put on ads "no pets" but some may change their mind once they meet you and your pet. This was the case for my fiance and I in the place we were previously renting (although it wasn't in Daly City).
If you're concerned about crime you can go to http://dcpd.crimegraphics.com/2013/default.aspx
there you can use the tabs on the side and enter dates to pull up crime information. Hope I helped. If you have any follow-up questions, feel free to email me.
