Local Intelligence
What Camas Homeowners Need to Know Before Submitting
Size & Zoning Rules
Any new square footage added to your Camas home counts against the same zoning envelope that governs ADU size, meaning large additions may affect your ability to add a future ADU. Camas's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Camas does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
If the addition creates a second unit or is later converted to a rental, Camas's ADU market supports approximately $1,880/month for a 2-bedroom unit.
Permit Process & Fees
Building Division permit fees for this project type typically range from $13,000 to $22,000 depending on project valuation and scope.
Addition permit packages submitted to Building Division must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus stamped structural drawings are always required for any load-bearing elements, second-story work, or new foundation.
Visit Building Division ↗Construction Cost Context
Camas's home addition construction costs run $150–$252 per square foot — a wide range driven by labor markets, local code complexity, and finish level. Our drawings are priced at a fraction of what a full-service architect would charge to produce the same permit set.
⚠ Common Pitfall in Camas
Camas quietly bundles a school impact fee into your ADU permit — even though your accessory unit isn't adding kids to a classroom, you'll still owe roughly 35% of the district's $6,650 school fee if the ADU sits detached from the main house. On top of that, because the city is in Seismic Zone D1, plan reviewers scrutinize detached ADU foundation and shear wall details more closely than a typical garage conversion, which can bounce your plans back for revisions if your engineer isn't used to Clark County's interpretation of the code. Budget for the water/sewer system development charge too — it's billed separately from the building permit and often surprises homeowners who only priced out the construction cost per square foot.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Camas ADU projects, both that permit timeline and per-square-foot cost figure look like statewide placeholders rather than numbers pulled from actual Clark County submittals, so I'd call the Camas Building Division and get two or three local contractor bids before you anchor a budget or schedule to them. With 35% of the market under HOA governance, don't overlook that a clean plan check doesn't guarantee a clean HOA design review — I've seen that step add just as much delay as permitting itself."

Common Questions
Camas Home Addition FAQs
Do I need a permit for a home addition in Camas? +
Yes — any structural addition to your home in Camas requires a building permit. This applies to room additions, second-story additions, sunrooms, and attached garages. You'll need permit-ready drawings before the building department will accept your application. Our packages are formatted specifically for Camas's submittal requirements.
How much does a home addition cost in Camas? +

Second-story additions cost more than ground-floor extensions due to structural requirements. Contact us to discuss drawing package options for your project.
What drawings are required to permit a home addition in Camas? +
Camas's building department requires: a site plan showing the addition's footprint and setbacks, floor plans for all affected levels, all four exterior elevations, an electrical plan, and energy compliance (Title 24 in California). Structural plans stamped by a licensed engineer are required for any load-bearing elements — included in our Premium package.
How long does the permit process take for a home addition in Camas? +
Plan check in Camas typically takes 8 weeks for home additions. Additions with structural components may require additional review. Complete, code-compliant drawings significantly reduce correction cycles — each cycle adds 3–6 weeks. Our drawings are engineered to pass on the first submittal.
What setbacks apply to home additions in Camas? +
Camas enforces minimum setbacks from property lines for all additions: typically 4–5 ft side setbacks and 5 ft rear setbacks, though these vary by zoning district and lot size. Your addition must stay within the buildable envelope. Our site plan documents existing and proposed setbacks and flags any zoning variances required.
Do I need structural drawings for a home addition in Camas? +
Yes, for most additions. Any load-bearing walls, new foundations, second-story construction, or roof structure changes require stamped structural drawings from a licensed engineer. California's CBC (California Building Code) and seismic requirements make structural plans mandatory for most addition types. Our Standard and Premium packages include stamped structural drawings.
How much do home addition drawings cost in Camas? +
Our permit-ready home addition drawing packages for Camas include everything your building department requires — floor plans, elevations, structural, and energy compliance. Every package is engineered for WA code compliance and formatted for Camas's building department. 14-day money-back guarantee.
Will a home addition increase my home's value in Camas? +
In Camas, where median home values are approximately $700,000, a permitted home addition adds square footage that appraisers value as part of the home's gross living area. Return on investment varies by addition type — master suite additions, family room expansions, and additional bedrooms typically recoup 50–75% of project cost in appraised value in WA markets.
Can I add a second story to my home in Camas? +
Second-story additions are permitted in most Camas residential zones, subject to height limits and design review requirements. California generally requires ministerial permit approval, but some cities impose design compatibility or neighborhood compatibility review for second stories. Our drawings cover all levels including foundation upgrades, shear walls, and roof framing required for vertical additions.
