That's my position (no one else to do them really) I've no idea if it could still be spread by doing as you suggest, I think that's the big worry with it as no one really understands how it is spread currently. There was a study reported recently (in the last 24 hours) that it can live in the air for 2-3 hours, on cardboard for 24 hours and on stainless steel and plastic for 2-3 days. I guess potentially if you are infected it could be on anything coming out of your house on you including your ppe, touching door handles, gate handles, taps and goodness knows what else, even if you avoid touching shared things. Could it then areosolise from those things? I'd guess low chance, but who knows! It's unlikely though, right?
