ADUs and Home Additions in Camas, WA

Adding usable square footage to a house sounds simple until the planning actually starts. Space has to come from somewhere, and that somewhere is either a backyard, a side yard, or the footprint of the house itself. Custom ADUs and home additions in Camas, WA have to answer structural questions before they answer design ones, because new floor area changes how loads travel through the existing frame. Skipping that step tends to surface later as sagging floors, doors that stick, or a roofline that never quite drains the way it should. Careful planning at the front end prevents nearly all of it.


Land in this part of the state climbs. Prune Hill, an extinct volcanic vent, gives much of the city its elevation and its grade, and the city sits at roughly 712 feet above sea level. That terrain shapes what a second structure or a new wing can do on any given lot, since a sloped site affects where a foundation can sit and how water moves away from it afterward. Residential ADU and home addition work in Camas, WA is usually a conversation about the ground long before it becomes a conversation about floor plans.


We bring over 20 years of remodeling work to every job, which is why Covas Construction has provided professional ADUs and home additions in Camas, WA, with the structure sorted out before anything gets framed. Our process starts with a walkthrough of the existing house rather than a catalog of layouts, because the house decides what the addition can be. We talk through what the finished space needs to do, what the lot allows, and what the existing systems can carry. Then we build to that plan and keep you updated as it moves.

Hillside Lots and the Planning They Add to ADUs and Home Additions in Camas

Sloped ground is the single biggest variable on a lot here. A flat backyard lets a detached unit sit on a straightforward foundation, while a grade change may call for a stepped foundation or a partial daylight level beneath the new floor. Neither situation is a problem on its own. Each simply needs to be known before a layout gets drawn.


Drainage follows grade, and anything placed on a hillside sits somewhere in that path. Roof runoff, downspout routing, and the ground slope around a new wall all decide whether water leaves the structure or collects against it. Poor routing, rather than the addition itself, is what creates trouble, and it is straightforward to plan around when it gets caught early.


Access matters just as much on a graded site. Concrete trucks, lumber deliveries, and excavation equipment all need a usable route to the work area, and a steep approach can change where materials stage and how a foundation gets poured. Knowing that in advance keeps the build sequence realistic.

How Utility Connections Shape an ADU and Home Addition Build

Running services to a new living space is the part homeowners think about last and planners think about first. An accessory dwelling unit with a kitchen and bathroom needs water supply, drain and waste lines, venting, power, and usually its own heating, and all of that has to come from somewhere on the existing property.


Water and waste lines are typically the governing constraint on a detached unit. Supply lines need protection from freezing and a route that avoids tree roots and future digging, while waste lines need consistent fall toward the existing connection point. On an attached addition, the work is shorter but still has to thread through framing already in place.


Electrical capacity is the other common question. A full second living space can push an older service panel toward its limit, so most professionals check the existing panel and its load before committing to a layout. Upgrading a panel is routine work when it is anticipated. It becomes disruptive only when it surfaces halfway through a build that was planned without accounting for it.
