Redmond ADU Plan Review
Plan review is when Redmond actually reads your drawings. Building, land use, fire, and public works reviewers each mark up the plans, then the city issues a consolidated set of correction comments. Most of the calendar time on an ADU permit lives here.

What plan review actually means in Redmond
In review, each discipline checks the plans against the code it owns. Building reviewers look at structural, life-safety, egress, and energy code. Land use checks setbacks, height, lot coverage, parking, and ADU-specific zoning standards. Fire looks at access, hydrants, and sprinkler thresholds. Public works looks at right-of-way, driveway, stormwater, and utility connections.
Reviews typically run in parallel, but the slowest discipline sets the schedule. If land use takes 8 weeks and building takes 4, the project is in review for 8 weeks, not 12.
When reviews complete, the city consolidates comments into a corrections package and bounces the project back to the applicant. Almost every ADU permit gets at least one corrections cycle.
REDMOND NOTE
ADU plan review in Redmond is checked against RZC 21.08.220 — the zoning code section that defines ADU purpose, type, size, and siting standards.
Why Redmond plan review hits the high end
- 01Plan completeness at intake — incomplete packages add full review cycles, not just days
- 02Whether the project triggers SEPA, design review, shoreline, or critical-areas review
- 03Reviewer workload at the time of submittal
- 04Whether outside agencies (water/sewer district, fire district, county) are in the review chain
- 05How quickly the applicant returns corrections in later cycles
Where the dollars actually come from
- 01Most cities invoice the bulk of plan review fees after intake based on valuation
- 02Hourly review fees can apply when reviewers spend more than the included hours — check the city's published fee schedule
- 03Re-review hours after multiple corrections cycles are usually billed at the same hourly rate
Exact dollar amounts vary by project. Use the Redmond fee schedule linked below for the current numbers.
Common homeowner mistakes
First reviews almost always produce corrections. Plan calendar and budget for at least one full corrections cycle before issuance.
Submitting architectural plans without structural calculations or WSEC energy compliance forms guarantees a corrections cycle just to add what should have been there.
Public works comments on driveway approach, frontage improvements, or stormwater management are often more disruptive than building comments — and easier to design for early.
Plan Review checklist
These are typical artifacts for an ADU project at this phase in Washington cities. Exact requirements depend on the project and the current Redmond submittal checklist — verify with the city before submitting.
- Designer of record available to issue review-comment responses
- Structural calculations and details
- Washington State Energy Code (WSEC) compliance forms
- Stormwater planRequired for most ADU projects that add impervious surface.
- Geotech reportRequired on steep slopes, fill, or sensitive soils.
- Side-sewer / utility availabilityRequired when adding a new dwelling unit.
When to call a pro
A contractor who has cleared recent Redmond ADU permits knows which reviewer flags what, and can pre-empt the comments that always show up before the package even gets uploaded.
Redmond Plan Review questions
How long does Redmond ADU plan review take?
For an ADU project in Redmond, WA this phase typically runs 7–12 weeks. Complex sites, missing reports, first-time submittals, or busy permit seasons trend toward the upper end. Resubmittals reset the clock for that round. These ranges are project-level averages — verify the current published timeline with Redmond for your specific project.
What does plan review cost in Redmond?

Which Redmond department handles plan review?
Redmond Planning & Community Development handles this phase; submittals and status live in https://mybuildingpermit.com/. See City of Redmond — Planning & Community Development: https://www.redmond.gov/469/Residential-Permits.
What's the most common reason plan review stalls in Redmond?
Incomplete drawings, missing structural/energy/stormwater pages, and corrections returned without a comment-response letter are the usual stall causes in Redmond. We pre-screen every submittal against the current Redmond checklist before it goes to the city.
Do I need a contractor or designer for Redmond plan review?
Not legally required for owner-applicants, but in Redmond every ADU permit eventually touches building, land use, fire, and public works review tracks. A designer of record is effectively required because review comments are technical and time-bound.
How do I check Redmond permit status during plan review?
Redmond publishes live status inside https://mybuildingpermit.com/. The same record carries application data, review comments, fee balances, and (after issuance) inspection results.
