What Is Involved in an ADU Construction Project?
Fine Finishes & Final Walkthrough
From there, we move smoothly into high-performance insulation upgrades, seamless drywall textures, painting, and precision finish trims. Our skilled installation crew handles the fine detailing with total accuracy—fitting space-saving cabinetry, connecting your chosen plumbing fixtures, hanging secure interior doors, and laying down beautiful, durable flooring. We manage the entire timeline from the initial teardown to the final detailed cleanup, giving you a complete, hassle-free experience.
Planning, Site Prep & Infrastructure
Developing a legal, comfortable accessory dwelling unit requires careful planning and strict management. Our comprehensive workflow kicks off with an in-depth consultation to map out your backyard space or garage footprint, finalize material selections, and establish clear, detailed budgeting. Once construction begins, our crew handles clean, organized preparation. We update foundational underground plumbing connections, tie into your main utility services, and route advanced electrical sub-panels to ensure your new unit has completely independent, reliable power.
How Much Does An ADU Or Garage Conversion Cost?
Conversion vs. Ground-Up Build: Transforming an existing garage structure keeps infrastructure budgets highly cost-effective, while constructing a brand-new detached standalone unit involves fresh foundation layouts and utility trenching, representing a higher-tier structural investment.
Fixtures & Material Selections: Choosing standard, heavy-duty flooring and functional kitchen packages keeps your budget highly controlled, while opting for luxury stone surfaces, vaulted ceiling features, and high-efficiency smart appliances allows you to fully customize your property value and future rental pricing.
