Continuity mistake: Rebecca says Danny had reseeded the grass, and it would take 3 weeks to grow, and that's why Jesse had to build the playset inside instead of the backyard. But later that very same day, when Stephanie throws Kimmy's shoes into the backyard, you can see the lawn has fully grown grass.
Other mistake: When Danny enters the bathroom, there is a window in the wall next to the door with daylight coming through. Yet according to the house plan, the stairs to the attic are supposed to be located behind this wall- the door to them is even seen in the background as the pizza guy passes them in the hallway.
Plot hole: When the Tanners are having their family meeting about moving to a new house, Jesse shares a story of an incident in the house which occurred on March 4, 1989. He says that, on that date, Danny painted the banister without informing anyone beforehand, and that Jesse slid down the banister on his way to a job interview. But if this happened in March of '89, then Jesse already had a job working with Joey in advertising, not to mention his own schedule with the Rippers band. And as busy as Jesse was in these two areas, there would've been no need for him to work an additional job.
