ADUs and Home Additions in Hockinson, WA

Property with room to build changes what is possible, but it does not make the decision any simpler. A detached unit can sit almost anywhere on open acreage, which means the siting choice ends up carrying more weight rather than less. Detached ADUs and home additions in Hockinson, WA depend on getting that placement right, since access, utilities, drainage, and the relationship to the main house all follow from where the structure finally lands. A well chosen location makes the rest of the build straightforward from day one. A poor one creates extra work that lingers for the length of the whole project.


Lots here run large. The community spreads across about 14 square miles with roughly 436 residents per square mile, which leaves most properties with substantial open ground, and parcels measured in acres are common throughout. Rural home addition projects in Hockinson, WA therefore involve real site work, since the distance between an existing house and a new structure affects every service that has to reach it, every trench that has to be cut, and every piece of equipment that has to get out there.


With over 20 years of remodeling work behind us, Covas Construction builds dependable ADUs and home additions in Hockinson, WA on properties where the site itself drives the design. We walk the parcel before we talk about layouts, because access routes, slope, and the distance to existing services decide what actually makes sense. Once the placement is settled, the rest of the plan tends to follow quickly. Our own crew carries the project from that very first site visit through to the final finishing work.

About Hockinson, WA

Camas, WA, is a charming city known for its scenic surroundings, welcoming neighborhoods, and strong sense of community. Located in Clark County, the city offers a balance between natural beauty and a vibrant small-town atmosphere. Residents enjoy tree-lined streets, well-maintained parks, and a historic downtown area that reflects the city’s long-standing heritage. Life in Camas moves at a comfortable pace, with local events and outdoor recreation playing an important role in everyday life.

Elim Lutheran Church began construction in 1893 and held its dedication in 1899 on land donated by Ambrosious Hokanson, whose log home had housed the congregation from 1884. A bell tower followed in 1907 and the building was expanded in 1952. Over its history the church has served as a post office and hosted events tied to Hockinson Fun Days.


Elevation across the area averages roughly 387 feet. Most of the community is served by the Hockinson School District, with parts falling into the Battle Ground School District. The population grew 28 percent between the 2010 and 2020 counts after declining during the decade before that.

Siting an ADU or Home Addition on a Large Hockinson Parcel

Placement on a large parcel is a design decision rather than a default. Distance from the main house affects privacy and convenience in opposite directions, and the right answer depends entirely on who will use the space. A unit for an aging parent usually sits close to the house. A rental or a studio often works better farther out.


Service runs follow that choice directly. Water supply, waste, and electrical all have to travel from existing connection points to the new structure, and every additional foot adds trenching and material. On rural properties, homeowners also need to confirm how an added dwelling interacts with private water and septic systems before any layout gets finalized.


Equipment access is the constraint people underestimate most. Concrete trucks, excavators, and material deliveries all need a route that will carry their weight, and soft ground or a long driveway can determine where a foundation is even practical. Walking that route early avoids redesigning a site plan once the schedule is already set.

How New Framing Ties Into an Existing Home on an Addition or ADU

Connecting a new structure to an older one is where the real engineering happens on an addition. The existing wall has to transfer new loads, the new floor system has to meet the old one at the correct height, and the roof has to shed water at the junction without relying on sealant to do work that framing should be doing.


Foundations are the usual starting point for all of it. New footings have to reach undisturbed soil at the proper depth, and they are typically tied into the existing foundation rather than simply butted against it, so the two move together. Differential settlement between an old foundation and a new one is what produces cracks years later.


Where the roofs meet deserves equal attention. A valley or a wall-to-roof junction concentrates water in one place, and proper flashing, underlayment, and slope are what keep it dry over time. Most professionals detail those connections during design, since a junction drawn correctly is far simpler than one corrected after the fact.
