Thank you for reaching out to ask2.extension.

According to my app this is a red house spider.  They typically don’t bite humans, but can.  They don’t affect humans very much, but could have a mild reaction to its venom.  However they can have more effect on a dog or cat.

You can find their webs in dark and cool areas such as a corner of a wall.  You can usually find a round egg sack near their web.

The adult is usually under 1/2 an inch.

I hope this helps.
