We start with your property
We walk the yard or the rooms in question with you and talk about who the new space is for and how it will be used.

Need More Space at Home—or a Separate Place for Family?Let’s Plan an ADU or Addition.
Your family is growing, but you don’t want to leave your neighborhood. You may need another bedroom, a larger living area, or room for a parent moving in. Or you want family nearby while giving them their own space.
An ADU could provide a separate home for your parents, an adult child, or a tenant. A home addition expands your existing house. An ADU creates a separate living space. We’ll visit your property, discuss what you need, and help you understand which approach makes sense for your family and budget.

Zoning and city requirements come first
Before developing the design, we review setbacks, building size, height, and access, and coordinate with the city’s planning department on what is allowed.
One team, start to finish
Design, permits, and construction are handled by the same licensed general contractor.
THE SPACE YOU NEED
ADU and room addition services
Build a detached ADU
A new, self-contained home in the yard with its own foundation, roof, entrance, and utility connections. It gives the most privacy and keeps most of the construction away from your house.
Add an attached ADU, junior ADU, or garage conversion
These options use part of an existing structure, from a shared wall to space inside the house or garage. We evaluate the slab, headers, and roof framing before recommending this route, because a garage was not built as a living space.
Add on to your home
A room addition expands the house you live in with a new bedroom, a primary suite, or more living space. We plan how the new foundation, floor, and roof tie into the existing house.
LAYOUT, UTILITIES & FINISHES
ADU and addition materials and options
Layout and room sizes
Plan the bedrooms, kitchen, bathroom, entry, and storage around who will live in the space and how it will be used.
Utility connections
We review the electrical service, water, sewer, and heating and cooling the new space needs, so any upgrades are planned into the project from the start.
Exterior and interior finishes
Choose roofing, siding or stucco, windows, flooring, cabinets, and fixtures, including matching the existing house where the new space should blend in.
OUR ADU AND ADDITION PROCESS
Our ADU and room addition process
We visit your property and understand your plans
Your construction consultant will meet with you to discuss who will use the space, which rooms you need, your budget, and your timing. We’ll look at the existing house, the available space on the property, and construction access. We’ll then review zoning and city requirements before moving forward with the design.
Our design team works with the architect and engineer
Together, we’ll develop the layout and plan the foundation, structure, and utility connections. For an addition, we’ll work through how the new rooms connect to your existing house. For an ADU, we’ll consider its entrance, privacy, and relationship to the main home. Our design team will help you select materials, visit showrooms with you, and prepare a 3D rendering so you can see the proposed space before construction.
We coordinate the plans, city approvals, and utilities
Our office team will coordinate the architectural and engineering plans and submit them to the city’s planning and building departments as required. We’ll manage submissions, coordinate responses to city comments, and work with the architect and engineer on revisions. We’ll also coordinate with local utility providers when new connections or service upgrades are needed.
We order the materials and schedule construction
After you approve the design and selections, we’ll coordinate material orders with our preferred vendors using our contractor pricing. Once the required permits are approved and delivery dates are confirmed, we’ll schedule construction. We’ll discuss site access, which parts of your property will be affected, and any temporary interruptions to your household.
We build the structure and complete the rough work
Our construction team will complete the site preparation, foundation, framing, roofing, windows, and exterior doors according to the approved plans. For an addition, we’ll also make the planned connections to the existing house. We’ll install rough plumbing, electrical, and heating and cooling systems, and your project manager will coordinate inspections at the required stages.
We complete the interior and finishes
After the required inspections are approved, we’ll move forward with insulation, drywall, painting, flooring, and the finishes included in your plans. If the project includes a kitchen or bathroom, we’ll complete those installations, including waterproofing and required testing, followed by fixtures, appliances, and final connections.
We complete final inspections and walk through the space with you
We’ll coordinate the required final city inspections and approvals. Your project manager will walk through the completed space with you, review any remaining items, and explain how to care for the materials and use the installed systems.
Throughout construction, your dedicated project manager will coordinate the day-to-day work and keep you informed.

ADU and room addition FAQs
Should I build an ADU or a room addition?
It depends on whether you want a separate place for someone to live or more space in your own home. An ADU is a complete second home with its own kitchen, bathroom, and entrance. A room addition expands your current home and follows the ordinary zoning rules for the main house.
Can I build a detached ADU in my backyard?
In many cases, yes. State law gives ADUs in residential zones a more straightforward approval path, but the standards for your lot still depend on its zoning and setbacks. We confirm what is possible for your property during the lot review.
Can you convert my garage into an ADU?
Often, yes. A garage conversion reuses an existing structure, but the slab, headers, and roof framing need to be evaluated, because a garage was not built as a living space. We explain what the conversion would involve after looking at the garage.
Will my ADU or addition need a permit?
Yes. We prepare the plans, coordinate the engineering and energy documentation, submit them for your address, and respond to plan check comments. We then schedule the required inspections through the final sign-off.
What affects the cost of an ADU or addition?
The size and type of the project, site access, foundation needs, the distance to water, sewer, and electrical connections, any panel or service upgrades, and your finish selections all affect the scope. Design, engineering, and permit requirements may also matter. We discuss these factors after seeing the property.
How long does an ADU or addition take?
The schedule depends on the scope, design decisions, engineering, plan check and approvals, material availability, and site conditions. We discuss timing as the plan develops and keep you updated during construction.
Can you help with an existing unpermitted unit?
Tell us about it during the consultation. State law provides a route to legalize some older unpermitted ADUs, and we can talk through whether it may apply to your property.
