ADU Construction and Design Process
Each project begins with a planning session to assess the client's needs, budget, and design preferences. The design and construction teams work together to develop a layout that fits the available space and the homeowner's goals. Throughout the build, the company manages permitting, inspections, and scheduling to keep the project on track.
Westside ADU Builders uses quality building materials and applies attention to detail across each phase of construction — from structural work through to finishing. The company positions itself as a full-service ADU contractor, handling the process from concept to completion.
For clients considering a detached ADU or backyard cottage, the team conducts a site review and feasibility analysis before any work begins. This helps ensure the proposed structure is viable within local regulations and the property's physical constraints.
For attached ADUs, the process follows a similar path — a consultation to define scope, followed by coordinated design and construction phases. The company handles all associated permitting and compliance requirements.
Garage conversion projects are also part of their service offering. Converting an existing garage into a livable ADU unit can be a cost-effective way to add usable space without expanding the building footprint. Westside ADU Builders assists clients through the conversion process, including any structural modifications and finish work required.
Junior ADU (JADU) Services
Westside ADU Builders also specializes in Junior ADU construction. A JADU is created by converting existing interior space within a primary residence — often a spare bedroom or similar area — into a self-contained unit. Because JADUs are built within the existing structure, they typically involve lower costs, shorter build times, and a more straightforward permitting process compared to larger ADU types.
Benefits of a Junior ADU can include:
- Lower overall development cost compared to detached or attached ADUs
- Faster construction timeline
- Simplified permit requirements
- Potential increase in property value
- Flexible use — rental income, guest quarters, home office, or housing for family members
The company's JADU services include initial consultation and feasibility review, permit acquisition, professional construction and finishing, and a final walkthrough upon project completion.
In addition to construction, Westside ADU Builders offers ADU design and architecture services. These cover site analysis, custom design development, 3D renderings, material and finish recommendations, and permit-ready documentation. The design team can also provide guidance on how to configure an ADU for specific uses, such as rental income, elder care, or a home workspace.
