INABNET’S ROLE

The Project
One infill lot. Three homes. One accountable schedule.
At 4779 62nd Street, in San Diego's College Area near SDSU, Inabnet served as Construction Manager on a project pairing a renovated main residence with two brand-new accessory dwelling units built behind it — sharing a common firewall to maximize the site.
Inabnet was engaged directly by the developer to oversee the general contractor's day-to-day execution — holding the schedule, protecting the budget, and reporting progress straight to the ownership group throughout construction. Three structures were active on one residential lot at the same time: a main house with three bedrooms and two bathrooms, a compact one-story ADU with two bedrooms and one bathroom, and a two-story ADU with up to five bedrooms, two bathrooms, and a private rooftop deck.
The result is proof of a different kind of value Inabnet brings to a developer's team: independent oversight that keeps a hired GC honest on schedule and budget, on a site with zero room for coordination mistakes.

Architecture & Site
Two ADUs, one shared firewall, no wasted footprint
Behind the renovated main house, the two new ADUs were built to share a common firewall — a design decision that maximized buildable square footage on a tight infill lot. ADU Two rises two stories to a private rooftop deck; ADU One stays single-story and efficient. Keeping both structures moving in parallel, on a live residential street with limited staging room, required exactly the kind of schedule discipline Inabnet was brought in to enforce.
The Challenge
Three structures, one lot, no margin for slippage
A main house remodel and two new-construction ADUs, sharing a single infill lot in a dense College Area neighborhood, left little room for scheduling conflicts or cost surprises. Inabnet wasn’t the general contractor here — the job was to hold a hired GC accountable, on behalf of a developer who needed reliable visibility into progress.
- Three structures under construction simultaneously on one residential lot
- A shared firewall between the two ADUs demanding precise sequencing
- Oversight of a third-party GC, not direct self-performance
- Direct reporting to the developer, with schedule and budget visibility expected at every stage
The Execution
Construction management that protected the timeline
Inabnet stepped in as Construction Manager, overseeing the general contractor’s execution from the developer’s side of the table — not swinging hammers, but making sure the crews stayed accountable to the plan.
- Built and enforced a shared schedule across three concurrent structures
- Tracked the GC’s progress and draws against budget throughout the build
- Verified quality and finish consistency across all three units before sign-off
- Reported status directly to the developer at every milestone
- Delivered the project on schedule and on budget, with a smooth construction phase throughout

Why It Matters
The oversight developers need on a multi-structure infill build
Not every developer needs a general contractor. Some need someone in their corner watching the one they’ve already hired. 4779 62nd Street shows what that looks like in practice.
Three structures, one lot, one hired GC — and a Construction Manager reporting straight to the developer to make sure schedule commitments and budget lines held from groundbreaking to final walkthrough. That’s the discipline a developer needs on any project where the GC relationship benefits from independent oversight.
For a developer weighing whether to bring in a construction manager on their next infill or ADU project, this is the kind of documented, on-schedule, on-budget delivery that makes the case.
What this project demonstrates
- Independent construction management overseeing a third-party GC
- Schedule and budget discipline across three concurrent structures
- Direct, transparent reporting to the developer throughout the build
- Coordination of a shared-firewall ADU pair on a constrained infill lot
- A smooth construction phase, delivered on schedule and on budget
