Hallahan General Contracting
Company Overview
Daniel F. Hallahan General Contracting has operated for 35 years. My expertise lies in ADUs, room additions, master suites, comprehensive home building, and kitchen and bath remodels.

As a builder, I take immense pride in what I create. I invite you to request a no-obligation proposal. Thank you, Dan.
I have been in the industry since 1988. 35 years of dedicated service. Always verify licenses for any complaints against unlicensed individuals. I take pride in my craftsmanship. I regard every project as if it were my own residence. I work hand-in-hand with my customers from start to finish. Maintaining communication is essential for both my clients and myself. Don’t hesitate to reach out with any inquiries.
My journey started when I was just a kid. I am the middle child. My father passed away when I was just 12 years old. My mother raised three boys on her own: me at 12, and my brothers who were 14 and 10. At 14, I began my career as a laborer. Growing up, my father was an engineer who constantly built and designed, and I found joy in learning from him. After that, I earned my high school diploma, attended community college, and spent a year at Penn State. I returned to home building and found great satisfaction in it. I established my business in Long Beach in 1988 after moving there in 1987. I aim to construct with pride, enjoying the process of building dream homes. I want all to see that Dan Hallahan was the builder of that project when it’s done!

Recommended Customer Reviews

Hallahan General Contracting did an amazing job on my room and bathroom addition. Would definitely recommended

Dan is the man.. so nice and totally attentive. Great work!! Will totally use his services again

Hallahan General Contracting is the best construction company I have ever dealt with! Most contractors say one thing and then do another. Hallahan General contracting showed nothing but professionalism from start of the job until the finish and met all timelines. Would highly recommend.

I called Dan to come out and quote out a ADU for my Mother as she needs assistance and having her with us would be the best situation. He was on time, totally understanding of our needs and 100% professional every step of the way. I would recommend him for any ADU or general contracting needs that you may have.

The owner of this company is a rude and selfish person. After parking his work truck in a compact parking lot and screaming from my window to have him move his car so I can get out because he has completely trapped me in. He said ""didn't you see me come in"" and I said yes didn't you hear me yelling and proceeds to calling me a bitch. He moves his truck up but only leaving me room to get out through the trees and bushes and then backs it back up into me! I was standing on the side in the dirt almost hitting a tree because he decided he didn't want to stop backing up until he hit me! The way this person is disgusting and disrespectful!!

Hallahan general contracting has built two projects I worked on providing the designs and architecture. He's now doing a 3rd very complicated large scale project. The years of experience pays off. The work is tight tolerances and clean finishes. Making the structures not look like an addition is key to building in the City as almost no one does a new home from scratch. Matching old with new, working with older homes, updating them to the newest codes, he gets them done and the clients ask for more work after it's done. So I refer him a lot.

If anyone is out there looking for a professional, experienced and reliable contractor, it is Daniel F Hallahan! Not only was he meticulous in his work but he also gave us design ideas that made our family room addition so much more than we had imagined. He has a great crew and Dan is a hands on Contractor. He also stayed on budget and actually saved us money throughout the building of our family room. I would highly recommend Hallahan General Contracting. Thanks Dan!
