Local Intelligence
What Longview Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Longview — Building Division will not accept a permit application without them. Longview's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Longview currently requires owner-occupancy on the primary parcel — meaning one of the units (the main home or the ADU/conversion) must be your primary residence.
Homeowners in Longview who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,000/month.
Permit Process & Fees
Building Division permit fees for this project type typically range from $2,107 to $3,732 depending on project valuation and scope. Plan check runs approximately 6 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building Division as part of a permit application must include a site plan, floor plans, all four elevations, an electrical plan, and energy compliance documentation — plus if structural changes are involved, a licensed engineer must stamp the structural drawings.
Visit Building Division ↗Construction Cost Context
Longview's adu / renovation construction costs run $210–$640 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 Longview
Many older Longview neighborhoods, especially in the Highlands and near downtown, still run on original 1940s-50s clay sewer laterals, and the Building Division will require a sewer scope inspection before they'll sign off on your ADU permit if your lot connects to one of these lines. If the camera finds root intrusion or bellying pipe, you're looking at a lateral replacement — often $8,000-$15,000 — before framing inspections can even be scheduled. Because Longview sits in Seismic Zone D1, plan reviewers also tend to scrutinize foundation-to-framing connection details more closely than in nearby Clark County, which can add a review cycle if your engineer isn't used to Cowlitz County's stricter interpretation of the state seismic code.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, both the timeline and cost-per-square-foot figures here are blank or missing entirely, which tells me they're likely unverified state-level placeholders rather than real Longview numbers — I'd call the Building Division directly and get at least two local contractor quotes before budgeting anything off this data. What the data doesn't show is how much a low HOA prevalence (2%) can vary block-by-block here, so don't assume your specific lot is HOA-free just because the area average is low."
Market Context
Longview has a median home value of $340,000. Comparable renovation projects in this market typically add 27% to resale value.
Neighborhoods in Longview with the strongest renovation and resale value potential include Old West Side, Third Avenue, New West Side, Broadway, Highlands. Historic cottages/Colonials on tree-shaded lots directly adjacent to downtown, Lower Columbia College, and PeaceHealth St. John — premium walkable rental demand with larger-than-average legacy lots.
Permit Process
Permit applications are reviewed by the Building Division, with a plan check timeline of approximately 6 weeks. Permit fees in Longview range from $2,107 to $3,732 depending on project scope. Design review: Yes - in historic districts only.
Longview falls within Seismic Design Category D1, which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Longview Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Longview? +
You need accurate floor plans for: permit applications (required by Longview's building department for any structural work), refinancing or home equity loans, selling your home (accurate square footage documentation), renovation contractor bidding, HOA design review submissions, and insurance claims. Our as-built drawings capture your home's exact current dimensions.
What is an as-built floor plan and why do I need one in Longview? +
An as-built floor plan documents your home as it currently exists — including all room dimensions, door and window locations, wall thicknesses, and square footage. These are required when the original permit drawings are unavailable or the home was modified without permits. Longview's building department requires accurate as-builts when you apply for renovation or addition permits on older homes.
How much does floor plan drafting cost in Longview? +
Our floor plan drafting packages for Longview cover measured floor plans for all levels, room labels, door and window schedules, and verified square footage. Local drafting services typically charge $1,500–$4,000 for comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Longview home? +
You provide basic measurements (room dimensions, door/window sizes) and photos of each room. Our drafting team converts these into accurate CAD drawings with precise dimensions, wall thicknesses, and notations. For permit-grade as-built drawings, we may request additional measurements or a site visit from a local partner. We serve all Longview neighborhoods remotely.
What format are the floor plan drawings delivered in? +
We deliver drawings in PDF (for printing and permit submission) and DWG/DXF (AutoCAD-compatible format for contractors, engineers, and architects to work from). All drawings are formatted to Longview building department standards and include title block, scale, and code notations required for permit submission.
Can you draft floor plans for a rental property or multi-unit building in Longview? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Longview. Multi-unit buildings are priced based on the total number of units and floors. Contact us for a custom quote if your property has more than 4 units.
Will accurate floor plans increase my home's value in Longview? +
In Longview, where median home values are around $340,000, inaccurate or missing square footage records can suppress list price and appraisal value. Professional as-built drawings establish defensible square footage for appraisers and buyers. Unpermitted additions documented and legitimized through permit drawings can recover thousands in appraised value.
Do I need floor plans to get an ADU or addition permit in Longview? +
Yes — Longview's building department requires accurate floor plans as part of any ADU, garage conversion, or addition permit application. Our packages combine floor plan drafting with the full permit-ready drawing set (site plan, elevations, electrical, Title 24) needed for plan check submittal. If you only need the floor plans themselves, our Starter package covers that.
Can you draft floor plans from old blueprints or photos in Longview? +
Yes — we can redraft from original blueprints, scans of old permit sets, hand-drawn sketches, or room photos combined with your measurements. We regularize old drawings to current CAD standards and update them to reflect any modifications made since original construction. This is a common service for Longview homes built before the 1990s.
