Other mistake: The configuration of the front side of the house does not match the configuration from the inside. The outside view looking at the house from the street indicates (1) there are no rooms to the right of the garage (when inside there are rooms on the side of the garage). Also when looking at house from street side, to the left of the front door the house comes forward. When inside, (at least in episode 13, season 3) the inside of the house does not extend forward towards the street.
Continuity mistake: When Badger is talking to the cop at the start, a guy behind them gets on his bike and cycles off behind a pillar but never appears the other side of the pillar. Given the width of the pillar you should see him instantly. He just vanishes. (00:02:00)A Demon
