1. You can park on the street anywhere you find free space (not yellow marked curb), passenger side of car against curb. Steep walk up driveway to front or side door. 
2. Driveway is built to serve two houses. For most cars with low clearance enter at angle from the left side and aim for tires to nestle onto the concrete slabs on the right. Once at top of driveway, best to back into space. Parking must be strategic but there is enough space! Red cone on drive way would indicate that back-yard parking is full.
