ADU Planning & Construction
An ADU can create flexible space without requiring homeowners to leave the property they already value.
​
Potential uses include multigenerational living, independent space for adult children or parents, guest accommodations and long-term rental housing where permitted.
Cedar helps homeowners evaluate the type of ADU that may make sense for the property and then coordinates the project from planning through construction.

Detached ADU
Is a detached ADU Right for Your Property?
For properties with appropriate space, a detached ADU can provide greater privacy and independence from the primary residence.
​
But available yard area alone does not determine feasibility.
Building location, site access, utilities, topography, foundations and other property conditions can materially influence design and construction cost.
​
Cedar begins by evaluating these factors before a homeowner commits to a specific design.
Multigenerational Living
Creating Space for Multigenerational Living
One of the most compelling uses for an ADU or addition is creating independent space for family while maintaining proximity to the primary household.
​
The design should consider more than square footage.
Privacy, accessibility, entrances, kitchens, bathrooms, outdoor space, parking and the relationship between households can all influence how successfully the finished space functions.
Residential Remodel
Whole-Home Remodeling in Oceanside
When an existing home no longer works for the way you live, comprehensive remodeling can reconfigure and modernize the property while preserving the location you value.
​
Cedar coordinates substantial renovations involving multiple rooms, structural modifications, building systems and finishes through one construction process.
Home Additions
An addition may be the right solution when the homeowner wants new space integrated directly with the existing residence.
​
Projects may include:
​
Primary suites
Additional bedrooms
Home offices
Expanded kitchens
Family rooms
Guest accommodations
​
Cedar evaluates how the addition interacts with the existing structure, utilities and overall home before construction begins.
The Cedar Difference
Plan Before You Build
Major residential projects involve interconnected decisions.
Changing the floor plan can affect structure.
Moving a kitchen can affect plumbing and electrical systems.
Adding living space can affect utilities, foundations and site work.
Cedar's planning-focused approach considers these relationships early so homeowners can make better-informed construction decisions.
