ADUs & Accessory Dwelling Units in Camas, WA
Detached, attached, garage-conversion & junior ADUs.
For adus & accessory dwelling units in Camas, the right approach starts with the local housing. Camas is one of the Vancouver-metro communities in Clark County that we serve across Southwest Washington.
Near the western gateway to the Columbia River Gorge, Camas sees both heavy Pacific Northwest rain and real east-county wind, so adus & accessory dwelling units here means planning for moisture, rot resistance, and wind-rated exterior detailing — with James Hardie's HZ5 guidance where siding is involved.
This page covers adus & accessory dwelling units specifically for Camas. For the full service details, see our ADUs & Accessory Dwelling Units page, or explore all the remodeling work we do in Camas.
Camas's housing stock tells the story of a former paper-mill town turned fast-growing suburb. Downtown Camas and the streets closest to the old mill hold smaller early-to-mid-1900s homes with real character and, often, original single-pane windows and dated wiring. Up the hill, Prune Hill and Dawson's Landing are dominated by 1990s-onward and newer custom and semi-custom construction with open layouts and larger lots. Because Camas sits at the mouth of the Columbia River Gorge, homes here see stronger, more consistent wind than communities further from the river, which we factor into siding fastening schedules, flashing details, and exterior trim as much as the region's rain and moisture.
From Downtown Camas, Prune Hill, and Dawson's Landing to the rest of Camas, we match every adus & accessory dwelling units project to the age, construction, and condition of your specific home rather than a one-size-fits-all spec.

Does Washington make it easier to build an ADU?
Yes. Washington's 2023 statewide ADU law (HB 1337) requires cities and counties in urban growth areas to allow accessory dwelling units on most residential lots and limits how far local rules can go in restricting them, including owner-occupancy requirements. Cities like Vancouver layer their own local ADU standards on top, so we confirm the exact rules for your jurisdiction during feasibility.
How big can an ADU be?
State and local standards set baseline size allowances for ADUs, with the exact maximum depending on your lot size, unit type, and the specific city or county code that applies. We verify the number for your property before design rather than quoting a generic figure.
Do I have to live on the property to have an ADU?
Under Washington's statewide ADU law, jurisdictions generally cannot require the owner to occupy the property to build or keep a standard ADU, which is part of what makes them work as rentals. We confirm how the current rules apply to your specific plan and jurisdiction.
Can an ADU have its own utilities?
Yes. Depending on the design and your existing service, we run dedicated or sub-metered electrical, water, sewer, and gas as needed. For detached units this often means new trenching and connections; garage conversions may be able to tie into existing service. We plan the utility approach during design.
How long does an ADU take to build?
Timelines vary with unit type, site conditions, and the permitting queue in your jurisdiction. A garage conversion is typically faster than a ground-up detached unit. We give you a realistic, written schedule after feasibility and design.
Do I need a permit for adus & accessory dwelling units in Camas?
It depends on the scope. City of Camas — Community Development sets the requirements for Camas, and they can differ from neighboring Washington jurisdictions. We confirm what your project needs before we start and handle the permit and inspection process as part of the job.
Do you handle adus & accessory dwelling units on both older and newer Camas homes?
Yes. From Downtown Camas, Prune Hill, and Dawson's Landing to the rest of Camas, Camas in Clark County spans a range of housing eras and construction types, and we tailor the adus & accessory dwelling units plan to the age and condition of your specific home rather than a one-size-fits-all template.
