About
One advocate, one interest
ERES Management is an independent construction management practice serving custom residential projects across Los Angeles County and Orange County.
The practice
Built around the owner's side of the table
Building a custom home puts an owner across the table from a group of professionals who all do this for a living, several times a year. The owner usually does it once.
ERES exists to close that gap. We hold no financial relationship with the general contractor, take no markup on the trades, and gain nothing from a change order. That independence is the entire value of the role — it is what makes it possible to reject a change order, withhold a payment application, or tell you plainly that a bid is too high.
Engagements run from early feasibility through the 11-month post-construction walkthrough, or begin at the construction contract for projects already underway.
How we work
Three commitments
Verify, then pay
Pay applications are checked against work actually in place, with lien releases confirmed before funds are released.
Catch it while it's open
Veteran tradesmen inspect the milestones that get covered up. Defects are repaired before the contractor is paid, not discovered after drywall.
Make the number visible
Transparent, data-based bid formats. Direct costs disclosed, profit negotiated as its own line item.
Leadership
Jonathon Ennis
Founder/CEO, ERES Management.
Jonathon has spent more than three years in Los Angeles construction management while working as a boutique real estate developer. The two disciplines reinforce each other: development means underwriting a project before committing to it, and construction management means knowing what it takes to deliver one.
His network of general contractors, architects, and designers spans the full range of finish quality and budget, from cost-constrained builds to fully custom work — so the team assembled for a project fits what the project actually calls for.
He brings the same fiduciary standard to his custom home clients that governs his development work: acting solely in the owner's interest, controlling cost, raising build quality, and protecting value across the build.
