Local Intelligence
What Forest Grove Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Forest Grove — City of Forest Grove/Cornelius Building Division will not accept a permit application without them. Forest Grove's current ADU size cap is 720 sq ft — on the tighter end, which constrains larger conversion plans.
Forest Grove does not impose an owner-occupancy requirement, so you can rent both the main home and any ADU or conversion as investment units.
Homeowners in Forest Grove who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,375/month.
Permit Process & Fees
City of Forest Grove/Cornelius Building Division permit fees for this project type typically range from $2,500 to $9,000 depending on project valuation and scope. Plan check runs approximately 7 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to City of Forest Grove/Cornelius 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 City of Forest Grove/Cornelius Building Division ↗Construction Cost Context
Forest Grove's adu / renovation construction costs run $245–$470 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 Forest Grove
Because Forest Grove contracts its building review through Cornelius, your plans often sit in a shared review queue with another city's projects, which can slow things down in ways a Forest Grove-only office wouldn't. Since the whole area falls under Seismic Design Category D, the engineer of record has to run a site-specific soil and structural analysis to confirm whether you're D1 or D2 before footing details can be finalized — skip this and your first plan review will bounce back with corrections. Older Forest Grove neighborhoods, especially near the historic downtown core, frequently have undersized or clay sewer laterals, so the city may require a sewer scope inspection before signing off on your ADU's utility connection, adding both cost and a scheduling delay with Clean Water Services.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience with Forest Grove submittals, that $350/sqft figure and the 7-week timeline are really state-level estimates, not local truth — I'd get two or three actual contractor bids and call the City of Forest Grove/Cornelius Building Division to confirm current plan check queues before penciling out your budget. I've also seen plenty of "complete" drawing sets bounce back for corrections, so don't be surprised if that clock runs a few weeks longer in practice — Charlotte Pemberton, Senior ADU Design Consultant."

Common Questions
Forest Grove Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Forest Grove? +
You need accurate floor plans for: permit applications (required by Forest Grove'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 Forest Grove? +
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. Forest Grove'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 Forest Grove? +
Our floor plan drafting packages for Forest Grove start at $997 for a standard residential home. This includes 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 the same work. We deliver within 10 business days with a 14-day money-back guarantee.
How do you create floor plans remotely for my Forest Grove 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 Forest Grove 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 Forest Grove 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 Forest Grove? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Forest Grove. 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 Forest Grove? +
In Forest Grove, where median home values are around $400,000, 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.

Do I need floor plans to get an ADU or addition permit in Forest Grove? +
Yes — Forest Grove'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 Forest Grove? +
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 Forest Grove homes built before the 1990s.
