The Prison is not an exact replica...the largest lot available in the Sims 4 isn't big enough to get the right proportions...so let's call it an "inspired by" version with many of the same elements. I have it coded as a residence, because Rick and friends did indeed make the jail home. Will your sims?
The jail includes:
8 jail cell bedrooms with 2 beds each and toilets/sinks
3 additional bathrooms
a large shower room
a warden office
multiple guard offices with tv monitors
a guards work out room
a recreation room
a prison garden
The Prison fits on a 50x50 lot and has NO CC!
