No problem at all Kim!
As for USPAP vs. client requirements the law trumps both. So does ones safety. As we can't go onto private property to photo a comp without permission we can only indicate what we saw from the street, supply photos showing where the visibiliy ends from the street, insert an MLS photo into the report, comment, and move on.
You need to learn the difference between "can" (the state of what is possible, and "may" (the state of what is permissible). I "can" drive up a long driveway and take a picture without permission. How do I know this? Because I've already done it! I always knock first, and have never been denied permission. But if someone isn't home, I take the picture. It is neither illegal or unreasonable.
I don't do this very often, but I'm not such a scaredy-cat that it bothers me to do it if I can't see the house. Again, the GSEs, the VA, and FHA all recommend that the sale be verified and preferably with a party to the transaction, for instance the buyer or seller. Most often I verify comps with the listing or selling agents. But the preferred source of verification is the buyer or seller. Other than making a phone call, therefore, knocking on a front door is the best way to get that task done.
As for putting our safety at risk that's a no brainer. If you feel comfortable pulling into a driveway, getting out and introducing yourself and asking a bunch of people to move so you can get a picture that's your choice. It may work out 90% of the time. If you don't feel safe doing this I'd recommend following your instincts. Some areas are less safe than others, like it or not. We are not required to do this anyways and don't let the cowboys on this forum make you feel like less of an appraiser for not taking these extra steps and risks.
Good luck and be safe to all appraisers.
