Project Overview
Maximizing an existing lot without displacing the homeowner
6209 Mesita Drive showcases how thoughtful construction management can maximize an existing residential property through strategic infill development while allowing homeowners to remain in their home throughout construction.
The project includes a 303 sq ft addition to the existing residence while simultaneously constructing a new detached two-story residential building that contains two new ADUs in the backyard. This approach increases housing density without removing the existing home, creating additional living opportunities while preserving the established neighborhood character.
Because the property remains occupied throughout construction, every phase requires careful planning, sequencing, communication, and coordination to minimize disruptions while maintaining safety and construction efficiency.

Architecture & Site
Modern massing on a tight infill lot
The new detached building shares a clean, modern shed-roof profile — painted plaster exterior, deep window openings, and a low roofline that steps down toward the rear property line. Built on a 5,775 sq ft lot directly behind an occupied home, the project leaves no margin for sequencing mistakes: the home addition, garage demolition, and new ADU framing are all happening within feet of the existing residence and a shared side yard.
The Execution
Construction Management
Inabnet serves as the Construction Manager for the 6209 Mesita Drive development, acting as the owner’s representative throughout every stage of construction. Rather than serving as the General Contractor, Inabnet provides independent oversight to ensure the project remains on schedule, within budget, and meets the highest quality standards.
Managing simultaneous work on an occupied residence, a home addition, demolition, and the construction of two new ADUs requires continuous coordination between the owner, design professionals, contractors, subcontractors, inspectors, and utility providers.
By providing independent construction management, Inabnet helps ensure that complex residential developments remain organized, efficient, and aligned with the owner’s objectives from groundbreaking through project completion.
Throughout construction, Inabnet is responsible for:
- Representing the owner's interests throughout construction
- Managing project budgets and cost control
- Coordinating scheduling across multiple scopes of work
- Monitoring quality assurance and construction progress
- Overseeing contractor coordination and field communication
- Managing change orders and owner decision-making
- Identifying project risks before they impact schedule or budget
- Coordinating inspections and code compliance
- Providing transparent reporting and routine project updates
- Maintaining construction momentum while minimizing impacts to the occupied residence

Why It Matters
The value of professional construction management
6209 Mesita Drive demonstrates the value of professional construction management on complex residential infill developments where multiple construction activities occur simultaneously on an occupied property.
Successfully coordinating a home addition, demolition, utility upgrades, and the construction of two new ADUs requires far more than simply managing contractors. It demands proactive planning, communication, scheduling, quality control, and problem-solving to protect the owner’s investment while minimizing disruptions to daily life.
As San Diego continues encouraging higher-density residential development through ADU programs, projects like 6209 Mesita Drive illustrate how experienced construction management helps homeowners confidently navigate increasingly complex construction projects.
What this project demonstrates
- Construction management representing the owner's interests
- Simultaneous coordination of an occupied residence and new construction
- Home addition combined with two new ADUs
- Efficient urban infill development on a single residential lot
- Multi-phase scheduling and contractor coordination
- Budget, schedule, and quality management throughout construction
- Modern residential design integrated into an existing neighborhood
- A scalable model for homeowners pursuing additions and ADU developments throughout San Diego
Once construction is complete, this case study will be updated with professional photography, completed project metrics, owner testimonials, and final construction statistics. This project highlights Inabnet’s role as a trusted Construction Manager, demonstrating how independent project leadership helps owners successfully deliver complex residential developments while protecting quality, budget, and schedule from start to finish.
