Menlo Park homeowners typically choose from several ADU options depending on lot size, property layout, and long-term goals.
A detached ADU is a standalone structure built separately from the main home, often located in the backyard. This option provides maximum privacy and flexibility and is commonly used for rental income, extended family living, or independent space.
An attached ADU is connected to the existing residence and usually constructed as a home addition. This option works well when homeowners want to expand living space while maintaining architectural continuity with the primary home.
A conversion ADU transforms an existing garage or interior space into a fully functional living unit. Conversion ADUs are often the fastest and most cost-effective option because they utilize existing structures and utilities.
Homeowners planning an ADU often explore additional upgrades such as kitchen remodeling in Menlo Park, bathroom remodeling, full home remodeling, or home additions to improve comfort and long-term value.
As an experienced ADU contractor in Menlo Park, we follow a structured, step-by-step process designed to keep your project organized, predictable, and fully compliant with local zoning and building requirements. From the initial evaluation through final city approval, our team manages every phase of the ADU build so homeowners can move forward with confidence.
We begin with an in-depth consultation and site evaluation to review Menlo Park zoning regulations, setbacks, lot size, access points, and existing site conditions. During this phase, we also discuss your goals, budget, and intended use for the ADU to confirm feasibility and identify the most efficient path forward.
After confirming feasibility, you receive a comprehensive proposal outlining the full scope of work, estimated construction timeline, and budget expectations. This step establishes transparency early in the process, clearly defining what is included and helping prevent unexpected changes later on.
Our architectural and engineering team develops custom ADU plans tailored specifically to your property while complying with Menlo Park building codes, zoning regulations, and energy requirements. Each design focuses on efficient layouts, functionality, and long-term usability to ensure your ADU performs well and adds lasting value.
We manage the full permitting process, including plan submissions, revisions, and coordination with the City of Menlo Park. Our familiarity with local approval procedures helps reduce delays, address plan-check comments efficiently, and keep your project moving forward.
We guide you through selecting finishes, fixtures, and materials that align with your design preferences, durability needs, and overall budget. From cabinetry and flooring to appliances and exterior details, this step helps personalize your ADU while keeping decisions organized and on schedule.
Once permits are approved, construction begins. Our dedicated project managers oversee trades, inspections, scheduling, and quality control throughout every phase of the build. This hands-on oversight ensures consistent progress and professional workmanship.
After construction is complete, we conduct a detailed walkthrough with you and coordinate all required final inspections. This step ensures every detail meets expectations and complies with Menlo Park requirements before final sign-off.
Your ADU is complete, fully approved, and move-in ready. Whether used as a rental unit, guest house, or additional living space, your new ADU is built for comfort, functionality, and long-term value in Menlo Park.

The timeline for building an ADU in Menlo Park typically ranges from 6 to 12 months, depending on the ADU type, design complexity, city review timelines, and overall construction scope. Each phase of the process contributes to the total duration.
Most ADU projects in Menlo Park follow these general stages:
Planning and architectural design: approximately 6–10 weeks

The cost of building an ADU in Menlo Park depends on several factors, including unit size, ADU type, site conditions, utility connections, and finish selections. Because each property is different, ADU costs can vary based on scope and construction requirements.
In general:
Garage conversion ADUs are typically more cost-effective because they use existing structures and utilities.
Attached ADUs often fall into a mid-range cost category due to structural integration with the main home.
Detached ADUs usually cost more because they require new foundations, framing, roofing, and full utility connections.
Partnering with an experienced ADU contractor in Menlo Park like W & W Builders Group helps establish a realistic budget early, define a clear scope of work, and reduce the risk of unexpected costs during construction.
