In San Francisco, renting illegal units is a double whammy as you technically cannot receive any compensation for an illegal space while at the same time you are unable to evict anyone due to the eviction control in San Francisco.

I've had a few clients permit unpermitted units and it cost about double what they expected. 

The following are stacks on this, pressing on conversion, credibility, call 2 actions, and depending on the campaign time-limitation comes into the picture which is a reinforcer for C2A. 

Ensure that your platform profiles have high-quality pictures, compelling bios, lead magnets (e.g., free guides, eBooks), and clear calls to action.

then ( at least in Oregon) contractor would sue lot owner for unjust enrichment.. and lot owner ends up paying double for many of the trades..

I just had a deal that I was helping @Monica Pope with here in Clevleand fall apart because it was a triple that was a legal double.

Dont focus on petty things and understand the big picture. 

You have a de minimis exception which is set at $2,500, and it can be doubled to $5,000 if you follow certain strict and tedious accounting practices known as AFS.

@Kathy Creighton-Smith, the Internal Rate of Return (IRR) is the metric that captures the entire picture of the total return of owning real estate. 

I have them check it out for me, FaceTime me, take pictures and get an inspector in there and it just works out for me.
