Behan Builders is a San Francisco–based concrete contractor and general contractor. Michael Behan runs the company and works on-site through every phase of every project. Licensed, insured, and accountable.
Behan Builders is owned and operated by Michael Behan. We're a small crew based in San Francisco, small on purpose. The kind of contractor most homeowners say they wish existed: actually present, actually accountable, actually finishing on schedule.
We've worked across every district of San Francisco, from Sunset bungalows to Presidio Heights restorations to Bernal Heights hillside builds. The work runs from straightforward repairs to full remodels and new ADUs.
What we don't do: take on more than we can handle, juggle four projects at once, or send a different sub every week. The same people show up to your home every day until the job is done.
When you sign a contract with Behan Builders, Michael is the person who shows up on site. Every day, through every phase. Not on Tuesday mornings between checking other jobs. Every day.
That's why we keep the company small. It's also why we say no to projects we can't actually staff. A contractor with ten jobs running can't be on any of them.
Start a conversation →Michael is on your project every day, not running four other jobs from a truck. The person who signed the contract is the person doing the work.
Every project starts with a written scope and a fixed price. No hourly billing. No open-ended cost-plus. No surprise invoices midway through.
We pull every DBI permit your project needs and handle inspections through to final sign-off. The administrative work isn't your problem.
If a repair makes more sense than a replacement, or if the cheaper option is also the right one. We tell you. Our recommendation isn't tied to the size of the invoice.
We give you a schedule we can actually hit, then communicate weekly during the build. If something slips, you hear from us before you have to ask.
We finish the punch list before walking away. If something needs attention after the job is done, you can call us. We'll answer.
Michael and his team did exceptional work on our home. From the initial walkthrough to the final punch list, they were professional, communicative, and meticulous. The project came in on schedule and the finish quality was outstanding.Clayton Kopp, Google Review
We hired Behan Builders for a full home renovation and could not be happier. Michael is a genuine craftsman who takes real pride in his work. He's responsive, transparent on pricing, and stands behind everything he does.Sophie Allauzen, Google Review
Michael was recommended to us and he exceeded every expectation. Honest, hardworking, and clearly knows San Francisco construction inside and out. I'd hire him again in a heartbeat.Malcolm Hillan, Google Review
