I have a commercial building that is short on parking.

I agree but first time owning a 4 unit building, my attorney suggested giving them 2 months free rent to avoid any exposure but they're definitely trying to shake me down. 

I love solving problems and building so this was just what I needed.

The city gave me 3 options: 1) return the unit to a garage, 2) get an architect or draftsman to draw up the building plans and then pull permits, or 3) get a structural engineer to "stamp" it and say that it's up to code.

It's essential to review the plans carefully, ensuring they align with your investment goals and local building codes before making a purchase.From my experience, BlueBeam provides the most seamless and fast collaboration between people on the project (architects, builders, owners, investors, etc.)

It is my humble opinion that the legislator who wrote the law (he represents tenants exclusively), was building a business for himself and trying to create an industry for attorney's to represent tenants.

If you have a good agent and a good relationship with them, don't risk creating a misunderstanding by leaving them out of a step. 

We informed our tenants about the possibility of building two ADU's in our property about 2 months ago. 

If so file a complaint with the building department / state licensing commission3.
