More Space. More Flexibility. More Possibility From Your Property.
Cedar Construction helps North County San Diego homeowners plan and build custom accessory dwelling units designed around their property, lifestyle and long-term objectives.
Whether you're considering a detached backyard ADU, an attached living space or a garage conversion, our approach combines thoughtful planning, design coordination, budgeting and experienced construction management.
We help you move from an initial idea to a well-defined construction project—understanding the opportunities, identifying potential challenges and coordinating the details that matter.
Build More Possibility Into Your Property
An accessory dwelling unit can transform the way you use your property.
For some homeowners, it creates independent living space for aging parents or adult children. For others, it provides guest accommodations, additional flexibility or an opportunity for rental income where permitted.
But building an ADU involves much more than selecting a floor plan.
Property conditions, design, utilities, permitting, construction costs and the relationship between the new unit and the existing home all influence the project.
Cedar Construction brings these considerations together through a coordinated construction process.
Our goal is to help you understand what you're building, why you're building it and how the project can be executed effectively.
Custom ADU Construction Services
Every property is different. Cedar helps homeowners evaluate the construction approach that best aligns with their property and objectives.
DETACHED ADU
A detached ADU is a separate residential structure located on the same property as the primary home.
Detached units can offer independent living space and greater separation between households while allowing homeowners to create a design suited to the property.
Cedar coordinates the planning and construction considerations associated with detached units, including site preparation, foundations, utility connections and construction access.
ATTACHED ADU
An attached ADU connects to the existing residence while providing independent living facilities.
This option may be appropriate when homeowners want to expand the existing structure rather than build a separate unit.
Cedar evaluates how the new space will integrate with the existing home, including structural considerations, access, utilities and privacy.
GARAGE CONVERSION
Converting an existing garage may provide an opportunity to create additional living space using an existing structure.
However, a garage conversion can require significant upgrades involving foundations, framing, insulation, electrical systems, plumbing and other building components.
Cedar evaluates existing conditions and coordinates the construction requirements necessary to transform the space into a functional dwelling.
ADU Construction Backed by Business Strategy
An ADU is both a construction project and a significant property investment.
The decisions made before construction begins can have a substantial effect on the project's cost, functionality and long-term usefulness.
Cedar approaches ADU construction with an emphasis on informed decision-making, disciplined planning and experienced project management.
