Residential ADU Construction by Global Arch Construction
Global Arch Construction helps Sacramento homeowners add space, flexibility, and value to their properties through professionally built accessory dwelling units. As an experienced ADU contractor, they work with homeowners to understand their goals and design solutions that fit both their needs and their lot.
Accessory dwelling units are among the more practical investments a homeowner can make today. Whether the goal is to house relatives, generate rental income, or simply expand available living space, a well-built ADU can serve multiple purposes over time. Global Arch Construction brings local knowledge and a structured process to each project, helping clients navigate Sacramento's zoning rules, setback requirements, and permitting procedures.
What Global Arch Construction Offers
Global Arch Construction operates as a design-build ADU contractor, meaning they handle both the design and construction phases under one roof. This approach keeps the project coordinated and reduces the back-and-forth that can slow things down when separate firms are involved.
Their services cover a range of ADU types, including:
- Detached ADU builder services — backyard cottages and standalone units
- Garage conversion contractor work — transforming existing garages into livable space
- Attached ADUs and in-law suite construction
Each project is tailored to the homeowner's specific property size, zoning classification, and lifestyle goals. Their team is familiar with making compact units feel functional and well-lit, which is particularly relevant when working with smaller footprints common in Sacramento neighborhoods.
Global Arch Construction provides clear cost estimates and works to keep projects within budget through smart material choices and efficient scheduling. They are also mindful of minimizing disruption to the surrounding property and neighborhood during construction.
The Build Process
Their process follows three main stages:
- Consultation and Site Assessment — They evaluate the lot, zoning conditions, and the homeowner's goals to determine what type of ADU is feasible.
- Design, Plans, and Permits — They prepare construction documents and manage the permitting process, keeping things on track with local regulations.
- Construction and Completion — From foundation and utilities through to interior finishes and final inspections, their crew handles the full build.
Most ADU projects take between 4 to 8 months from start to finish, depending on the complexity of the design and the permitting timeline.
Global Arch Construction holds an active contractors license through the Contractors State License Board and carries a General Liability Certificate of Insurance, providing homeowners with a baseline of professional accountability.
For Sacramento homeowners considering a detached ADU, a granny flat, a casita, or a garage conversion, Global Arch Construction offers a structured, locally informed approach to getting the project done.
