My partner and I are converting our single family home into a duplex and we were lucky enough to come across Decc. Mike has been phenomenal throughout the permit process. We were a little stressed taking on this large project, but Mike has been amazing, guiding us through the trials and tribulations that arise when working on a home built in the 1800’s. He presented great ideas during his walk through, and designed two fabulous units, easily overcoming what we thought were going to be major permit issues. Further, Mike was able to put us in contact with a construction company (555 construction) that specialize in this type of conversion. We recommended Mike to some close friends, who also conveyed a very positive experience. Thank you Mike!!!!!!!

I have now had the pleasure of working with Mike a few times and picked his brain dozens more. Simply put there is levels to this kind of stuff and Mike is at the top of his game. His ability to adjust his message from talking to city staff to contractors to home owners is impressive and you feel like you have a true partner in your project. One of the most impressive aspects of working with DECC Inc. was their ability to deliver permit on the day of closing. There was zero downtime and the team was able to get right to work.Having worked with multiple engineers in the past, there is good and bad, Mike and DECC Inc. are the best.

Mike and the team at DECC Inc. were an absolute pleasure to collaborate with. They were thorough, professional and provided the absolute highest quality of customer service from commencement to completion of the additional dwelling unit within my home. DECC Inc. essentially rescued me from a previously incompetent design firm and I cannot recommend their services highly enough. If I could rate 6 stars, I would.

I was referred to DECC Inc. to do drawings for my duplex conversion. Mike made the process easy and seamless with the various permit applications and submissions, along with drawings for my new property conversion. Great communication throughout the entire process, with updates along the way. We had our permits in hand the day our property closed, allowing us to start the conversion immediately with no time lost (time is money). Highly recommend Mike!
