Couple with Shih Tzu looking for a place to rent (Concord)

Hello, my girlfriend and i are looking for a place to call home.
I am 22 and she is 20.
We both have full time jobs.
We have one small dog (Shih Tzu) and have 2 cars.
We are looking for a room with private bathroom near concord CA.
With a budget if 800-1000 depending on size and location.
About me: i am 22.
I love to work on my car or others cars and currently trying to create a small business for car customization and repairs.
I do smoke so youd have to be okay with 420.
I Obviously do not smoke inside the house but i will occasionally go outside for a walk or just enjoy the view while smoking.
About her: she is 20.
Works with dogs, does makeup for fun and for profit.
And loves to relax when possible.
We are a young couple and would prefer a place that is calm and comfortable.
420 friendly.
And would allow me to occasionally work on the cars as needed (oil change and basic maintenance) our dog is potty trained and usually lets us know when she needs to use the bathroom.
She tends to be quiet but can bark when startled Any questions or information needed just email or text Please send a message with the keyword Room22 so we can weed out the bots and scammers.
Thank you for your time.
