When do I need an inspection?
After your building permit is issued, a City Building Inspector checks to make sure that your work is done according to code.
As a permit holder, you are required to arrange for each inspection. Building Inspections are requested online.
The required applicable inspections are listed on your Permit Inspection Card provide to you at the time of issuance by the City.
The City of Sammamish Building Division performs sequential visual inspection of work in progress that is under current city-issued Building, Plumbing, and Mechanical permits.
Do not cover or enclose any item without first having obtained an approved inspection by the City of Sammamish.
How do I schedule an inspection?
Regular building inspections are requested online and are scheduled as early as the next business day.
Can I find out when my inspection will be?
Inspections are scheduled in the morning the day of the inspection. You can check the schedule here.
The order is subject to change without notice, due to cancellations or other unforeseen events. (Building permits and approved construction drawings are required to be on site for the inspection.) The city of Sammamish does not provide specific inspection times.
How can I help to make my inspection a successful one?
Can more than one inspection be done on the same day?
Inspectors will only make one site visit per day. Call the inspector, prior to placing inspection request, to discuss feasibility of inspecting more than one scope of work during the inspection appointment. Call City Hall at 425-295-0500.
How do I check the status of an inspection?
Check inspection status here.
The inspection results can also be determined by looking at the on-site permit record: if the inspection line is signed, this signifies approval.
If the line is not signed, and a Correction Notice has been left on site, this indicates additional work is to be completed prior to sign-off of inspection.
Are there starting and stopping times for construction?
Yes, construction times as allowed per Sammamish Municipal Code, section 16.05.030 are as follows:
Will a minor change in design require a permit revision?
In most cases, the answer is “yes.” Any change in foot print, wall configuration, or roof design requires a permit revision applied for through our Permit Center.
There are very few instances when the “revision” can be a field approved revision which does not require additional fees or review time for a permit “revision.”
The revisions that can typically be approved in the field are: a change in post or beam species or type, i.e. Parallam instead of Glulam beam; footing size; window header size, window size, etc.
These changes would typically required beam/gravity calcs to verify new sizing, and, if original structure was designed by an engineer, the changes would be required to be accompanied by a letter of approval of changes with original signature and wet-stamp of engineer of record.
How do I get my Certificate of Occupancy?
When do I need to hire an engineer? My project is quite simple.
Due to the potential of earthquake hazard in Washington most homes and additions require engineering.
Where structural elements do not meet the conventional construction requirements of the International Residential Code, those elements must be designed in accordance with accepted engineering practice.
One key item concerns the amount of solid walls in the structure. (See Construction Guidelines #2 - Braced Walls Continuous w/Openings)
Can I use engineering created for a project outside of Sammamish, for the same structure in Sammamish?
No, not unless the engineer of record provides a letter confirming that the calculations are also applicable to the specific site of proposed construction in Sammamish.
Engineering for projects in the city of Sammamish is required to be site specific.
What are the design criteria for projects in Sammamish?
When is a geological report required?
