Local Intelligence
What Sherwood Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Sherwood — Building Department will not accept a permit application without them. Sherwood's current ADU size cap is 800 sq ft — within the typical range for most floor plan configurations.
Sherwood 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 Sherwood who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,545/month.
Permit Process & Fees
Building Department permit fees for this project type typically range from $18,957 to $19,792 depending on project valuation and scope. Plan check runs approximately 5 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Building Department 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 Department ↗Construction Cost Context
Sherwood's adu / renovation construction costs run $200–$350 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 Sherwood
Many Sherwood lots sit on Clean Water Services (CWS) service territory, which means your ADU plans need a separate CWS Service Provider Letter before the city will even accept your building permit application — this can tack on 2-4 weeks and often triggers extra stormwater management requirements if your lot is near one of Sherwood's protected wetland corridors, like those around Cedar Creek or Rock Creek. Because Sherwood sits in Seismic Design Category D, the building department will also scrutinize your foundation and shear wall details more closely than a generic Oregon jurisdiction, especially if you're attaching the ADU to an older detached garage. Older Sherwood neighborhoods like Old Town also may have undersized sewer laterals, so expect the Public Works department to require a sewer scope inspection before approving your connection.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 5-week plan check timeline and $250/sqft cost are Sherwood state-level estimates, not local gospel — I've seen actual permit review here run well past that window once corrections come back, so get a quote from a local contractor and call the Building Department directly before you bank on either number. What the data also doesn't show is how much a complete, well-prepared drawing set can compress that timeline versus a first-time DIY submittal."
Market Context
Sherwood has a median home value of $560,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in Sherwood with the strongest renovation and resale value potential include Parrett Mountain View Estates, Renaissance Glen, River Terrace, Middlebrook, Daybreak. Large lots and high proportion of single-family homes make detached ADUs feasible and attractive for rental income.
Permit Process
Permit applications are reviewed by the Building Department, with a plan check timeline of approximately 5 weeks. Permit fees in Sherwood range from $18,957 to $19,792 depending on project scope. Design review: Yes - citywide (ministerial Residential Design Checklist Review required for ADUs; additional Old Town Overlay design standards and review apply in Old Town/Smockville areas).
Sherwood falls within Seismic Design Category Seismic Design Category D (typical for Portland metro/Washington County; verify site-specific SDS/SDC via Oregon Design Criteria Hub or USGS design maps), which affects structural requirements for any new addition tying into the existing structure.

Common Questions
Sherwood Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Sherwood? +
You need accurate floor plans for: permit applications (required by Sherwood'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 Sherwood? +
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. Sherwood'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 Sherwood? +
Our floor plan drafting packages for Sherwood 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 Sherwood 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 Sherwood 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 Sherwood 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 Sherwood? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Sherwood. 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 Sherwood? +
In Sherwood, where median home values are around $560,000, 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 Sherwood? +
Yes — Sherwood'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 Sherwood? +
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 Sherwood homes built before the 1990s.
