Common Uses in Keizer
Local Intelligence
What Keizer Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Keizer — Marion County Building Inspection will not accept a permit application without them. Keizer's current ADU size cap is 750 sq ft — on the tighter end, which constrains larger conversion plans.
Keizer 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 Keizer who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,100/month.
Permit Process & Fees
Marion County Building Inspection 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 Marion County Building Inspection 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 Marion County Building Inspection ↗Construction Cost Context
Keizer's adu / renovation construction costs run $315–$456 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 Keizer
Because Keizer contracts building review out to Marion County rather than running its own department, your plans get queued alongside county rural permits, and inspectors aren't always familiar with Keizer's specific zoning code overlays — this mismatch often means a homeowner has to personally clarify setback or lot-coverage rules that the county reviewer misapplies from unincorporated area standards. Many older Keizer lots, especially near River Road, still run on shared or undersized water laterals from the 1960s, so adding a second dwelling can trigger a costly Public Works requirement to upsize the service line before final sewer sign-off. Because the city allows short-term rental use, you'll also need to budget time for a separate Keizer business license and transient occupancy tax registration after your county building permit closes — a step people planning STR income routinely forget.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience reviewing Keizer submittals, that $450/sqft figure and the 7-week plan check window are Marion County state-level estimates, not locally verified numbers — I'd call Marion County Building Inspection directly and get two or three local contractor quotes before penciling out your budget. What the data doesn't show is that a 7-week estimate assumes a clean, complete drawing set on first submittal, and I've seen plenty of straightforward projects run 10-12 weeks once you factor in a routine round of corrections."
Market Context
Keizer has a median home value of $335,000. Comparable renovation projects in this market typically add 25.0% to resale value.
Neighborhoods in Keizer with the strongest renovation and resale value potential include Greater Gubser, Northgate, Hayesville, North Lancaster, Northeast Neighbors (Greater Northeast Keizer). Central, established single-family neighborhood with larger lots and strong access to Chemawa Rd and Salem jobs.
Permit Process
Permit applications are reviewed by the Marion County Building Inspection, with a plan check timeline of approximately 7 weeks. Permit fees in Keizer range from $2,500 to $9,000 depending on project scope. Design review: Other: No — generally no separate design‑review is required beyond standard permits, but front‑yard detached ADUs require an alternative design review (Type I‑C); design standards/overlay zones also impose zone‑specific requirements..

Common Questions
Keizer Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Keizer? +
You need accurate floor plans for: permit applications (required by Keizer'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 Keizer? +
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. Keizer'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 Keizer? +
Our floor plan drafting packages for Keizer 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 Keizer 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 Keizer 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 Keizer 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 Keizer? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Keizer. 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 Keizer? +
In Keizer, where median home values are around $335,000, 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 Keizer? +
Yes — Keizer'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 Keizer? +
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 Keizer homes built before the 1990s.
