Home Additions in Camas, WA

For home additions 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 home additions 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 home additions specifically for Camas. For the full service details, see our Home Additions 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 home additions project to the age, construction, and condition of your specific home rather than a one-size-fits-all spec.

• Second-story additions with structural engineering

• In-law and multigenerational suites with private entry
• Sunrooms and four-season rooms
• Foundations engineered for local soils and drainage
• Roofline and exterior matching to the existing home
• HVAC extension and mini-split, heat-pump-ready installation
• Electrical panel upgrades and circuit expansion
• Full interior finishing to match the rest of the house

1. 01

   Feasibility & Design

   We evaluate your lot, setbacks, soil and drainage conditions, and how the addition ties into the existing structure. Architectural plans are drafted around your layout, budget, and finish goals.

2. 02

   Engineering & Permitting

   Structural engineering is completed and we submit for permits with your specific city or county, including WSEC energy documentation. Foundation drainage and framing connections get particular attention in our wet, wind-exposed climate.

3. 03

   Foundation & Framing

   The foundation is excavated and poured to the engineered design, framing ties the addition into the existing structure with proper connections, and the new roof is integrated with correct flashing and drainage.

4. 04

   Mechanicals, Finishes & Handoff

   Plumbing, electrical, HVAC, insulation, drywall, flooring, trim, paint, and fixtures are completed. We match interior and exterior finishes to the existing home, pass final inspections, and hand off the space.

Typical timeline: Typically 3 – 8 months. We provide a written schedule after assessing your Camas home.

Permit requirements for home additions in Camas are handled through City of Camas — Community Development. Because Washington building rules — including the Washington State Energy Code and local amendments — vary from one jurisdiction to the next, we confirm what your specific address requires and pull the permits and schedule the inspections the scope calls for.

• Building permits are required for structural, electrical, plumbing, and mechanical work
• Exterior work such as siding, window, and roofing replacement typically requires a permit and inspection
• New construction and most remodels must meet the Washington State Energy Code (WSEC)
• Accessory dwelling units are governed by Washington's statewide ADU law (HB 1337) and city standards — we prepare and submit all applications
