every post above is not wrong
is the house slab on grade or basement?
makes a difference understanding water tolerance
first find the source and attempt to prevent it
next seek local remediation
looks to be coming from beyond the gate on the back side of your property?
can you post pics of the view from there?
visible low spot under the door with a strange elevation change
notice a patch at the wall bottom running towards the garage
sidewalk appears recent with standing water on both sides
probably not the first time
guess that once was a patio
shedding water from house towards the side and back neighbor
fence on the right sucking up extra moisture so something's new
wouldn't be surprised if next door was also recently sold and has a backyard full of fresh sod contributing to your mud
