Local Intelligence
What Bellingham Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Bellingham — Planning and Community Development Department will not accept a permit application without them. Bellingham's current ADU size cap is 1,000 sq ft — within the typical range for most floor plan configurations.
Bellingham 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 Bellingham who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,597/month.
Permit Process & Fees
Planning and Community Development Department permit fees for this project type typically range from $3,000 to $11,000 depending on project valuation and scope. Plan check runs approximately 8 weeks — though each correction cycle adds 3–6 weeks, which is why code-compliant drawings matter so much.
Floor plans submitted to Planning and Community Development 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 Planning and Community Development Department ↗Construction Cost Context
Bellingham's adu / renovation construction costs run $298–$570 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 Bellingham
If your lot falls within Bellingham's shoreline jurisdiction (a lot of properties near Whatcom Creek, Padden Creek, or the waterfront do), you'll need a Shoreline Substantial Development Permit or an exemption letter from Planning and Community Development before your building permit even gets logged — that review alone can tack on 6-8 weeks and often requires a critical areas report if you're near a stream buffer. Because the city sits in Seismic Design Category D, expect the plan reviewer to scrutinize your foundation-to-wall shear connections closely, especially on older lots with unpermitted additions already on the parcel, which can trigger a full structural re-survey of the existing house. Also budget for a separate sewer capacity check with Public Works — some older neighborhoods like the York or Sunnyland areas have undersized side sewer lines that need upsizing before a second unit can legally tie in, and that's a cost most contractors won't flag until after excavation starts.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, that $425/sqft and 8-week timeline are Bellingham-level estimates rather than verified figures, so I'd get at least two local contractor quotes and call the Planning and Community Development Department directly before penciling in a budget or start date. Also worth flagging — since you're in the coastal overlay, the CDP review adds meaningful time on top of standard plan check, something I've seen catch homeowners off guard more than once."

Common Questions
Bellingham Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Bellingham? +
You need accurate floor plans for: permit applications (required by Bellingham'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 Bellingham? +
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. Bellingham'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 Bellingham? +
Our floor plan drafting packages for Bellingham 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 Bellingham 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 Bellingham 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 Bellingham 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 Bellingham? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Bellingham. 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 Bellingham? +
In Bellingham, where median home values are around $495,000, 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 Bellingham? +
Yes — Bellingham'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 Bellingham? +
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 Bellingham homes built before the 1990s.
