What Are the Building Setbacks for an Accessory Dwelling Unit (ADU) in Poway, CA?

Building an ADU in The City of Poway

So if you’re looking to build an ADU in Poway, California, one of the questions you might have is, where can I put the ADU on the property? So, a very, very important question and the city of Poway allows us some flexibility there. So, we have to start with basic building setbacks, So the setbacks that you would have if you had a primary dwelling. 

Setback for an Accessory Dwelling Unit

So those are typically on a property zoned RRC in Poway, which is a very common residential zoning. In that zone, the front yard setback is typically 40 feet. So you’re 40 feet front yard, you’re going to have a side yard setback of 20 feet, and your rear yard setback is going to be typically 50 feet. So what you can do with an ADU, you have to abide by the front yard setback of 40 feet, they don’t allow an exception for that. However, on the side in the rear yards, they allow you to encroach into that area, you know that setback, Up to four feet from your property line on the rear and on the sides. So the one trick to that is, if you do go past typical setbacks of the 20 feet, or the 50 feet in the rear, you have to make sure that the ADU, any portion of it, that’s actually into that typical building setback. 

Residential Zoning for an ADU

So from four feet of the property line to the 20 foot mark, you have to be 16 feet or less to the average grade. So not to the actual slab of the foundation on the ADU but to the average grade. So you’re gonna actually take a tape measure, that 20 foot mark, if it’s a side yard, you’ll put a tape at the very top of your roof and you’ll measure down to the actual dirt, the average grade and you got to be at 16 feet or less at any portion of that that’s in that setback. And the same would go if you were past that 50 foot mark on the back part on the rear setback of the property. What they allow you to do, it’s really helpful because a lot of these lots are tight, but it allows you some flexibility to actually squeeze that at you into that space.
