Garage Conversion

Harbor City Garage Conversion — Harbor City, CA

Project Overview

About This Project

This Harbor City garage conversion transformed a standard two-car garage into a fully independent accessory dwelling unit (ADU) with its own bedroom, bathroom, kitchenette, and separate entrance. The project required structural modifications to replace the garage door with a load-bearing wall and window assembly, new foundation work for the bathroom wet area, and completely independent MEP systems including a dedicated electrical sub-panel, plumbing stack, and mini-split HVAC. STG Design Build navigated the complex California ADU permitting process and delivered a code-compliant, rentable living space.

Scope of Work

What We Delivered

  • Garage door removal and load-bearing wall construction
  • New foundation pour for bathroom wet area
  • Dedicated electrical sub-panel and circuit layout
  • Independent plumbing stack with sewer connection
  • Ductless mini-split HVAC system installation
  • Full insulation to residential R-value standards
  • Kitchenette with sink, countertop, and cabinetry
  • ADA-conscious doorway widths and bathroom layout

Project Highlights

Why This Project Stands Out

Garage conversions require navigating California's evolving ADU regulations, which govern setbacks, ceiling heights, parking replacement, and utility metering. STG's permitting expertise and design-build integration ensured this project met every requirement without costly revisions or re-submittals.

The Result

The homeowners gained a fully permitted, rent-ready living unit that generates monthly income while adding significant property value. The independent MEP systems mean the ADU operates without impacting the main home's utilities, and the quality of finishes makes it indistinguishable from purpose-built construction.
