Local Intelligence
What Shoreline Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Shoreline — Planning & Community Development will not accept a permit application without them. Shoreline's current ADU size cap is 1,200 sq ft — generous enough to accommodate most project types.
Shoreline 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 Shoreline who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,795/month.
Permit Process & Fees
Planning & Community Development permit fees for this project type typically range from $11,821 to $14,613 depending on project valuation and scope. Plan check runs approximately 13 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Planning & Community Development 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 Planning & Community Development ↗Construction Cost Context
Shoreline's adu / renovation construction costs run $245–$490 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 Shoreline
Many Shoreline lots near Puget Sound fall inside the Shoreline Master Program's coastal overlay, which means you'll need a Coastal Development Permit on top of your regular building permit — this alone can tack on 6-8 weeks and requires a separate environmental checklist reviewed by Planning & Community Development staff before they'll even look at your ADU plans. Because the city sits in Seismic Design Category D, engineers here often require additional shear wall reinforcement or foundation anchoring for detached ADUs, which can catch homeowners off guard when their contractor's bid jumps after the structural review. Also worth knowing: Shoreline's water and sewer lines are aging in several older neighborhoods like Richmond Beach and Ridgecrest, so Public Works may require a side sewer scope inspection before approving your utility connection — a step that's easy to miss if you're only budgeting for the ADU itself.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that 13-week timeline and $350/sqft figure are Shoreline-level estimates, not verified local numbers, so I'd get actual bids from contractors who've pulled permits in your neighborhood in the last six months before penciling in a budget or schedule. What the data doesn't show is that Coastal Overlay properties here almost always need a CDP review on top of standard plan check, which in my experience adds meaningful time — so please call Planning & Community Development directly to confirm whether your parcel falls inside that boundary."

Neighborhoods in Shoreline with the strongest renovation and resale value potential include Meridian Park, Hillwood, North City, Ridgecrest, Parkwood. Large lots and many single-family homes near transit corridors make Meridian Park highly suitable for detached ADUs.
Permit Process

Common Questions
Shoreline Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Shoreline? +
You need accurate floor plans for: permit applications (required by Shoreline'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 Shoreline? +
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. Shoreline'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 Shoreline? +
Our floor plan drafting packages for Shoreline 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 Shoreline 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 Shoreline 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 Shoreline 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 Shoreline? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Shoreline. 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 Shoreline? +
In Shoreline, where median home values are around $660,000, 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 Shoreline? +
Yes — Shoreline'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 Shoreline? +
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 Shoreline homes built before the 1990s.
