Our ADU experience in Oceanside
With SnapADU originally based in Oceanside, we know the city’s regulations and processes very well. Turnaround times at the city are faster than other nearby cities and we frequently obtain a permit within two rounds of review at the city. However, Oceanside ADU regulations are a bit more restrictive than some areas, for instance permitting 4′ setbacks for up to a 1000sqft unit; 1200sqft and two story ADUs are allowed but subject to setbacks for the underlying zone. Some of Oceanside is in the coastal zone and minor use permits are required in those areas, but may be processed in parallel with the building permit (so delays are minimal).

Why do homeowners in Oceanside build accessory dwelling units?
One of the great things about the building process is that we didn’t have to be super involved. There were things we had to decide, but basically it was great just being able to watch. There wasn’t a time when somebody didn’t get back to me – it was great.
The value of working with SnapADU was tremendous…. I got a lot of sleep at night. The level of service and quality of work surpassed all my expectations. I’m so glad there are still companies who are focused on customer satisfaction.
We decided to build an ADU for my mom. I was very overwhelmed. Then I found out about SnapADU through a neighbor. I think it’s great to have a company that does the whole process from start to finish. It takes out the stress that comes with construction.
