How long does it take to get a permit in Bellevue?

Official Bellevue permit times at a glance

In the report covering permits completed from August 3, 2025 through August 3, 2026, a new single-family building permit had a median processing time of 161 days and an average of 224 days across 251 completed permits. A major addition had a 159-day median and 230-day average, although that category contained only six permits.

Simpler residential permits moved faster. Single-family remodels had a 14-day median and 37-day average, while single-family additions had a 77-day median and 129-day average.

Use the median for a typical case

The median is the middle completed permit: half finished faster and half took longer. The average adds every permit's duration and divides by the total, so a smaller number of unusually slow projects can pull it upward.

For new houses, the 161-day median is a more useful typical benchmark than the 224-day average. The 63-day gap between them is also important. It shows that slow permits are not rare enough to ignore, so your schedule needs contingency.

New houses and major residential work

• New single-family house (BS): 161 median days; 224 average days; 251 completed permits.
• Major single-family addition (BS): 159 median days; 230 average days; 6 completed permits.
• Single-family addition (BR): 77 median days; 129 average days; 168 completed permits.
• Single-family remodel (BU): 14 median days; 37 average days; 187 completed permits.
• Structure demolition (BE): 91 median days; 140 average days; 54 completed permits.

Trade, tree, utility, and right-of-way permits

The permit type matters enormously. A permit that requires coordinated land use, building, utility, fire, grading, and right-of-way review should not be compared with a straightforward trade permit.

• Electrical alteration (BG): 16 median days; 31 average days.
• Mechanical alteration (BL): 47 median days; 71 average days.
• Plumbing alteration (BO): 17 median days; 32 average days.
• Tree removal only (GT): 17 median days; 40 average days.
• Residential right-of-way modification (TG): 13 median days; 24 average days.
• Side sewer for a new structure (UA): 20 median days; 96 average days.

What the official report measures

The rolling report groups completed applications by permit type and description, then shows the number completed, median processing days, and average processing days. It excludes over-the-counter permit types. Because it looks backward at completed permits, it describes recent outcomes rather than the current queue.

Bellevue also publishes separate annual permit performance data for state reporting requirements. That dataset answers a different question, so do not mix its figures with the rolling permit-type report.

What the number does not tell you

• It does not separate time the city was reviewing from time the architect or owner was preparing revisions.
• It does not predict whether your site will trigger critical-area, tree, utility, drainage, fire, or right-of-way issues.
• It does not show how complete or coordinated the original drawings were.
• A category with only a few completed permits is much less reliable than one with hundreds.
• It does not guarantee that a permit submitted today will match permits completed during the prior year.

Build a realistic permit schedule

1. Find the exact permit type and description that match your project. Do not use the overall average for all permits.
2. Use the median as the baseline, then add contingency based on the difference between the median and average.
3. Separate city review time from architect response time. Reserve consultant availability before comments arrive.
4. Record every submission, city response, and revision date so you can see where the elapsed time is accumulating.
5. Follow up after a reasonable period of inactivity instead of assuming the permit is still moving.
6. Do not lock a construction start, financing deadline, or move-out date to the median without schedule cushion.

A practical homeowner takeaway

For a new Bellevue house, the official rolling median is about five and a half months, not three months. A well-prepared project can move faster, while complex sites, multiple correction rounds, or slow consultant responses can push the process beyond the 224-day average.

The most controllable part is idle time. A homeowner cannot eliminate required review, but can make sure city comments reach the architect, revisions have a clear owner and due date, submissions are tracked, and inactive reviews are followed up before days become weeks.
