Built it before he managed it.
Five years as a plumber and crew owner. You learn what a real day's work looks like, where the budget actually goes, and which subs cut corners the second the GC walks off site. He used to run the crew.
From Closing to Keys
Most builders start at the green tag.
We start at closing.
MMR Development isn't a builder you hand plans to. We're your project lead from the day you own the lot to the day you collect keys — at the table for market analysis, floor plan, design, permits, utilities, CenterPoint, and the build itself.

Why a project lead
The expensive surprises happen before you break ground.
Most builders
MMR Development
Start when plans and permits are handed to them
Start before you've signed on the lot
You're on your own for floor plan decisions
We sit at the table — what pencils for the area, what rents, what builds clean
You hire a designer and pray they coordinate
We talk to the design group and shape the plans with you
You submit permits and hope
Alongside the design group through every step of submission, plan review, and city comments
Lot surprises are your problem
We find skeletons before plans are drawn — utilities, easements, fill, drainage
CenterPoint, water tap, sewer — your phone calls
Our phone calls. We've made them all before
One scope: the build
One scope: the project, end to end
The edge
Built by someone who’s been on every side of the build.
022022 – 2024
Managed it before he inspected it.
Two years as construction project manager on multifamily builds for a real estate investment firm. Draw schedules, lender reporting, cost-to-complete, contingency burn. He started thinking like the investor writing the checks.
032024 – 2026
Inspected it before he led it.
Two years as an ICC-certified building inspector and plan examiner. Hundreds of projects a year. He learned which framing details fail, which permits stall, and which layouts trigger a re-walk — and now builds with it.
