This is a 4-bedroom, 2.5-bathroom single family house.

It is not illegal as long as they aren't hidden and aren't in bedrooms or bathrooms...I have two in the common areas.

While there are some limits here (you don't need a pasta maker), asking about having a plunger in each bathroom closet is insane.

Keep in mind local zoning laws and market conditions in Portland versus Salem—Portland might offer higher rents but stricter regulations, while Salem could provide better cash flow opportunities.Your design approach has proven successful, so continue focusing on appealing upgrades like kitchens and bathrooms, but prioritize cost-effective and durable materials for rentals.

Doing a short term rental in a separated area that has its own designated, kitchenette and bathroom, would likely give you better returns and less headache.

In the event my landlord is interested in selling, I was wondering if I could add value in the short term by, say, converting part of the garage and/or covered porch into a bathroom and maybe a bedroom (currently 3 bed 1 bath).

What the city housing clerk is telling me is that there was a water leak from behind the sink pedestal on the second floor bathroom that has been running for a week. 

I've already renovated one of the bathrooms, and I’m planning to paint the interior, update the kitchen cabinets, possibly sand the wood floors, build a fence is a corner lot and increase the rent for the room since my tenant is currently renting the entire 3-bedroom, 2-bathroom house for $800 a month.

The 4 guests smoked marijuana in the house (strong smell), broke a window blind and a picture, put a hole in the bathroom wall, chipped an end table and worst of all vomited on the couch and front porch.
