What we build
Four things we build best
We keep our scope deliberately tight. Fewer job types, run by the same hands every time, means sharper estimates and schedules we can actually hold to.
Additions
Second stories, rear and side additions and bump-outs — new square footage tied properly into the existing structure, with engineering coordinated from day one.
Kitchens
Full kitchen remodels — new layouts, cabinetry, stone counters, tile and appliances, with the plumbing and electrical brought up to current code behind the finishes.
Bathrooms
Gut bathroom remodels — waterproofing done properly, curbless and accessible showers, tile, stone and fixtures. Sequenced so your house stays livable while we work.

The innovative craftsmen
Built like it’s ours
MAC BUILT is a small, hands-on Oakland contractor. That means the person who priced your job is the person on site — no layers between the estimate and the execution.
-
Estimates you can read
Line-item takeoffs with real quantities and allowances called out, so you know what is priced, what is an assumption and where the money actually goes.
-
Code and permits handled
Oakland and East Bay permitting, plan check comments, engineering coordination and inspections — we run the paperwork so the schedule doesn’t stall.
-
Clean, safe job sites
EPA Lead-Safe certified practices, dust containment and daily cleanup. Most of our work happens in homes people are still living in.
-
Greener by default
Build It Green and Casita Coalition member — efficient envelopes, electrification-ready mechanicals and durable, eco-friendly material choices. We hold to the reuse, recycle, repurpose mantra on every job — salvaging what is still sound, giving good material a second life in the work, and sorting the rest for recycling rather than sending it all to landfill.
How a project runs
From first walkthrough to final punch list
Every job follows the same five stages. You always know which one you are in and what happens next.
Walkthrough
We visit, measure, look at the structure and talk through scope, priorities and budget range.
Estimate
A written line-item proposal with quantities, allowances, exclusions and payment schedule.
Plans & Permits
Design and engineering coordination, plan check submittal and permit issuance.
Build
Scheduled trades, weekly updates, inspections signed off as each phase closes.
Closeout
Punch list, final inspection, warranty documents and a house cleaned up behind us.
