Local Intelligence
What Astoria Homeowners Need to Know Before Submitting
Size & Zoning Rules
Accurate floor plans are the foundation of any ADU, garage conversion, or addition permit in Astoria — Community Development Building Division will not accept a permit application without them. Astoria's current ADU size cap is 900 sq ft — within the typical range for most floor plan configurations.
Astoria 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 Astoria who document and legitimize their square footage correctly are positioning a home in a rental market where 1-bedroom units average approximately $1,305/month.
Permit Process & Fees
Community Development Building Division permit fees for this project type typically range from $2,500 to $5,000 depending on project valuation and scope.
Floor plans submitted to Community Development 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 Community Development Building Division ↗Construction Cost Context
Astoria's adu / renovation construction costs run $240–$530 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 Astoria
Because so much of Astoria sits on steep, unstable terrain left over from old landslide areas, the Community Development Building Division often kicks your ADU plans over to a geotech review before they'll even look at your foundation design — and that's on top of the Coastal Development Permit review required for anything in the coastal overlay zone, which can tack on 4-8 extra weeks depending on how close you are to the shoreline or bluff. Many older Astoria lots also still have narrow or shared sewer laterals from early 1900s construction, so the city may require a sewer scope inspection before hookup approval, and if the pipe's undersized you're looking at a costly upgrade the homeowner pays for, not the city. Since short-term rentals aren't allowed here, make sure your ADU plans clearly show long-term residential intent on paper, or you may get extra scrutiny during permit review.
Expert Verdict — Marcus Reid, Licensed Designer
"In my experience, both that permit timeline and cost-per-square-foot figure are missing or unverified here, which tells me they're likely generic state-level placeholders rather than anything specific to Astoria — call the Community Development Building Division directly and get a couple of local contractor quotes before you budget. What the data also doesn't fully convey is that Astoria's coastal overlay triggers a Coastal Development Permit review on top of standard plan check, and I've seen that add real weeks (sometimes months) to a project timeline that a first-time applicant wouldn't anticipate."
Market Context
Astoria has a median home value of $450,000. Comparable renovation projects in this market typically add 25% to resale value.
Neighborhoods in Astoria with the strongest renovation and resale value potential include Downtown Astoria, Uniontown, Upper Astoria, Lewis & Clark, Alderbrook. Highest walkability and rental demand in the city, sitting directly on the downtown jobs/restaurant/gallery corridor where renters want to live.
Permit Process
Permit applications are reviewed by the Community Development Building Division. Permit fees in Astoria range from $2,500 to $5,000 depending on project scope. Design review: Yes - in specific overlay districts (Uniontown, Bridge Vista, Riverfront Vision overlay zones, National Register Historic Districts, and adjacent to historic landmarks).
Astoria falls within Seismic Design Category D (Residential D2, Commercial D per OSSC; high Cascadia Subduction Zone vulnerability), which affects structural requirements for any new addition tying into the existing structure.
Properties within Astoria's Coastal Overlay Zone require a Coastal Development Permit in addition to standard building permits.

Common Questions
Astoria Floor Plan Drafting FAQs
When do I need professionally drafted floor plans in Astoria? +
You need accurate floor plans for: permit applications (required by Astoria'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 Astoria? +
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. Astoria'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 Astoria? +
Our floor plan drafting packages for Astoria cover 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 comparable work. Contact us for current pricing and to discuss your project. 14-day money-back guarantee.
How do you create floor plans remotely for my Astoria 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 Astoria 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 Astoria 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 Astoria? +
Yes — we draft floor plans for single-family homes, duplexes, triplexes, ADUs, condos, and small commercial properties in Astoria. 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 Astoria? +
In Astoria, where median home values are around $450,000, 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 Astoria? +
Yes — Astoria'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 Astoria? +
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 Astoria homes built before the 1990s.
