Thanks for the advice, I'm going to reach out to the county auditor for any permits.The vent is just a 14' x 6' inch slotted vent.

Many homes in the Seattle area are getting 50-60 offers and buyers are getting sweet-talked into paying $300k+ above asking price and waiving all contingencies after spending a 15 minute time window at the house, because all the slots to view the home get booked up and there isn't an opportunity to even do a pre-inspection even if the buyer wanted to. 

Getting a deposit also stops a customer from backing out , once the contract is signed I schedule a slot , order materials , get permits .

. :)I'd add Anza to the list which is close to Anza-Borrego Desert State Park and The Slot along with Julian and Borrego Springs which has a golf course and some really nice midcentury homes.I was just in Desert Hot Springs visiting the Desert X installations and have changed my mind about DHS.

DM is kinda like going to Vegas and playing the slots.

@Aaron TaylorYeah that makes slot of sense.
