Does that mean the addition was built without permits?

Please make sure you get permits and the town approves your idea first before you move forward.

Doesn’t look like you are doing anything that needs permits so that’s good.

I am a little embarrassed to ask this but after researching R-3 Zoning, I have a few questions:Information:     - I have a lot, nearly 6k square feet, in Phoenix AZ and it is zoned R-3     - It currently has two duplexes on it for a total of four units     - At least one of the units is an addition     - I am uncertain as to the permits, however I did purchase it this way and there were no questions or issues in inspection or appraisal     - I am considering adding another unit or two, or at the very least expanding a unit to add another bedroom.Questions:     - In reading the coding, I am not sure where I land (Conventional or Planned Residential Development - I am assuming conventional but unsure of the distinction)     - I am a little confused as to whether the rules for dwelling unit density are specific to number of units or number of structuresAny feedback would be so very appreciated!

Also the corrections needed to get it back to conventional will take a few months of engineering, permitting and county paperwork. 

Had to figure out local codes, permits, transient taxes, fees, collecting fees, HOA rules, business licenses and state taxes, insurance coverages, etc.

However, the drop in December 2018 housing starts should not be taken as an indicator of a long-term trend steep fall in multi-family housing starts, given that the housing authorizations (permits) rose 27 percent in December 2018 to 176,000 from 139,000 in December 2017.

When I went to go turn the power on, the power company said the electrical service is cut off at the street and that I need an electrician to get a job number from the power company and a permit from the building and once inspected by the building department that they would  than turn the power on. 

Always get your permits up front.

I just don't see a historic home in a preservation district requiring board approvals and permits ever being done in 6 months.
