A Second Home on Land You Own

Make Better Use of Your Property

An accessory dwelling unit can add useful living space without requiring you to purchase another property.

Some homeowners build an ADU to create rental income. Others need a private place for parents, adult children, guests, or extended family. An ADU can also provide a smaller home for someone who wants independence while remaining close to family.

Throughout Port Angeles, Sequim, Port Townsend, Port Hadlock, Chimacum, and surrounding areas, property owners are increasingly considering smaller, more efficient living spaces. In the current market, many people are choosing ADUs, additions, and remodeling projects instead of building a large custom home.

CKS Builders LLC helps clients move from a general idea to a practical construction plan. You may already know what type of ADU you want, or you may only know that you have unused property and want to understand the possibilities.

The process begins by looking at the site, discussing how the unit will be used, and identifying the steps required before construction can begin.

The Definition

What Is an ADU?

An accessory dwelling unit is a secondary living space located on the same property as a primary home.

Depending on the property and project, an ADU may be:

A detached backyard cottage
A small one-bedroom home
A two-bedroom rental unit
A guest house
An attached addition with separate living facilities
A converted qualifying structure
A compact home for a family member
A secondary residence designed for long-term rental use

The right type of ADU depends on the property, available space, utilities, zoning, access, budget, and intended use.

CKS Builders LLC can help you evaluate the construction side of the project and coordinate the planning, engineering, permitting, and specialty work needed to move forward.

Its Own Four Walls

Detached ADUs and Backyard Cottages

A detached ADU is a separate structure built on the same property as the main home.

This type of project can provide more privacy because the occupants do not share walls with the primary residence. It may work well for renters, guests, adult children, or family members who want their own space.

Detached ADUs are often designed as compact cottages with one or two bedrooms. The layout may include:

A full kitchen
A living area
One or two bedrooms
A bathroom
Laundry space
Storage
A small porch or entry
Separate utility connections where required
Dedicated parking or property access where possible

Steven has seen interest in smaller, straightforward ADUs that can fit on in-town properties with existing homes. These projects are often intended to create an additional rental opportunity without building something overly large or complicated.

Even a simple cottage requires careful planning. The rooms need to use the available square footage efficiently, and the placement of the structure needs to work with the rest of the property.

CKS Builders LLC considers how the ADU will relate to the main home, yard, access, utilities, privacy, and future use.

Income From the Lot

ADUs for Rental Income

One of the most common reasons property owners consider an ADU is the opportunity to create rental income.

01 / The Opportunity

Land you already own

A homeowner may purchase or already own a smaller lot with an existing house and want to add a compact second unit. A one-bedroom or two-bedroom cottage may provide an additional source of income while making better use of land that would otherwise remain unused.

When planning a rental ADU, it is important to consider more than the number of bedrooms.

What tenants actually use

A practical rental unit may need:

  • A private entrance
  • A functional kitchen
  • Adequate storage
  • Laundry facilities
  • A comfortable bathroom
  • Good natural light
  • Durable flooring and finishes
  • Separation from the main home
  • Reasonable parking and access
  • An efficient heating system
  • A layout that feels comfortable without wasting space

The goal is to create a unit that is straightforward to maintain and appealing to future occupants.

CKS Builders LLC can help property owners think through the layout and construction details so the finished ADU is practical rather than simply small.

ADUs for Family Members

An ADU can also provide housing for a parent, adult child, or another family member.

This arrangement allows relatives to live close together while maintaining more privacy and independence than they would have inside the same home.

A family-focused ADU may include:

A comfortable bedroom A private bathroom A walk-in shower A full or compact kitchen Laundry facilities Easy entry access Minimal steps where practical Wider movement areas Good lighting Storage A small living room

The design should reflect the person who will use the space. A unit intended for an older family member may have different priorities than a rental unit for a younger tenant.

It may be helpful to plan for long-term accessibility, even if every accessibility feature is not immediately required. Simple design decisions made during construction can make the space easier to use later.

CKS Builders LLC works with homeowners to understand both the current need and how the ADU may be used in the future.

Guest Houses and Flexible Living Spaces

Not every ADU is built for full-time rental or permanent family housing.

Some homeowners want a private guest space that can also serve other purposes when no guests are staying there.

An ADU may function as:

A guest cottage
A home office
A private space for visiting family
A studio
A hobby space
Temporary housing during a future remodel
A long-term rental later
A residence for a family member in the future

Planning for more than one use can increase the long-term value of the space.

For example, a room used as an office today may later become a bedroom. A guest house may eventually become a rental. Including a functional kitchen, bathroom, storage, and laundry area can give the building more flexibility.

CKS Builders LLC can help clients think through these possibilities before finalizing the design.

Every Inch Counts

Planning a Small Space That Still Feels Comfortable

ADUs are usually smaller than traditional homes, which means every part of the layout matters.

Where Small Plans Go Wrong

Poorly placed doors, oversized hallways, limited storage, or an inefficient kitchen can make the unit feel much smaller than it actually is.

Steven brings practical construction and layout knowledge to the planning process. Even when a client already has plans, he reviews how the rooms connect and whether the layout will work well in daily use.

Important planning details may include:

Kitchen placement
Appliance size
Cabinet storage
Bathroom access
Bedroom privacy
Laundry location
Window placement
Natural light
Closet space
Furniture placement
Movement between rooms
Mechanical equipment
Entry and exterior access

The goal is not to fit as many features as possible into a small building. The goal is to use the available space intelligently.

CKS Builders LLC helps clients focus on function while still creating a finished unit that feels comfortable and complete.

Start Where You Are

You Do Not Need Completed Plans to Get Started

Many property owners begin the ADU process without architectural drawings or a final layout.

You may know that you want a one-bedroom cottage, a rental unit, or a place for a family member, but you may not know where it should be located or how large it should be.

CKS Builders LLC can begin by discussing:

How you plan to use the ADU
How many people may live there
How many bedrooms you need
Whether the unit should be attached or detached
What part of the property may be suitable
How occupants will access the building
Where utilities may connect
What level of finishes you want
What budget you are considering
Whether future flexibility is important

Steven can walk the property, review the general idea, and help explain what may need to happen next.

If plans, engineering, surveys, or permits are required, CKS Builders LLC can help coordinate the process with the appropriate professionals.

Clients who already have plans can also contact CKS Builders LLC. Steven can review the design and suggest practical changes when the layout, room flow, or construction details could be improved.

Ground to Finish

Site Preparation and Construction

Building an ADU involves more than constructing the visible structure.

  • Fixtures and finishes
  • Exterior access and entry work

CKS Builders LLC handles many of the core building and carpentry portions of the project, including framing, siding, windows, doors, interior trim, and finish work.

Specialized work such as concrete, roofing, drywall, plumbing, and electrical is coordinated with appropriate subcontractors.

This gives the client one main point of contact for the overall project while ensuring specialized work is handled by the proper trades.

Before the First Cut

Permits, Engineering, and Project Coordination

ADU projects may require planning before construction can begin.

The exact requirements depend on the property, the proposed unit, the site, and local regulations. Factors such as setbacks, utilities, parking, lot size, access, and the placement of the main home may affect the project.

CKS Builders LLC does not assume that every property can support the same type of ADU. The property needs to be evaluated, and the required information needs to be confirmed before the project moves into construction.

The planning phase may involve:

Reviewing the property
Developing or adjusting plans
Coordinating engineering
Gathering subcontractor pricing
Planning utility connections
Selecting materials
Preparing permit documents
Responding to project questions
Building a detailed budget
Allow Time for It

Engineering and permitting can each take several weeks, depending on the project and current workloads. CKS Builders LLC keeps clients informed about the decisions that need to be made while those steps are underway.

Clear and Detailed ADU Budgeting

The cost of an ADU depends on several factors.

These may include:

The size of the unit Number of bedrooms and bathrooms Attached or detached construction Foundation requirements Site access Clearing and grading Utility connections Kitchen size Cabinetry and countertops Bathroom finishes Windows and doors Roofing and siding Heating Engineering Permits Interior finish level
Site Visit

The first step is usually a conversation and a site visit. Steven discusses the intended use, reviews the property, and looks at the visible site conditions.

Preliminary Range

For many projects, CKS Builders LLC can then provide a preliminary budget range. This allows the property owner to determine whether the general project direction fits the available investment.

Adjustments

If the original concept is above budget, Steven can discuss possible adjustments. The ADU may be reduced in size, simplified, or designed with more practical material selections.

Detailed Estimate

Once the client is serious about proceeding, CKS Builders LLC prepares a more detailed estimate. Steven uses detailed spreadsheets to show the different parts of the project and clearly identifies overhead and profit rather than hiding those amounts inside subcontractor pricing.

Choosing the Parts

Material and Design Guidance

An ADU may be smaller than the primary home, but it still requires many selections.

CKS Builders LLC helps organize the selection process and can direct clients toward suppliers Steven has worked with throughout his construction career.

The finish level should match the intended use. A rental unit may benefit from durable, easy-to-maintain materials. A guest house may include more custom details. A family ADU may prioritize comfort, accessibility, and long-term use.

CKS Builders LLC works with a range of styles, from modern and minimalist to traditional and custom designs.
