Inspections
16. 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.
17. How do I schedule an inspection?
Regular building inspections are requested online and are scheduled as early as the next business day.
18. 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.
19. How can I help to make my inspection a successful one?
20. 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.
21. 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.
Construction
22. Are there starting and stopping times for construction?
Yes, construction times as allowed per Sammamish Municipal Code, section 16.05.030 are as follows:
23. 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 a 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 Glu-Lam 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.
24. How do I get my Certificate of Occupancy?
Engineering
25. 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)
26. 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.
27. What are the design criteria for projects in Sammamish?
Land Use/Planning
28. Where can I build on my property?
The City does not directly regulate where a house or other structures is built on your property; location of buildings is regulated by protection of specific features as follows:
29. How do I split my lot into two or more lots?
The first step is to schedule a pre-application conference with the city of Sammamish to discuss the proposed “short subdivision” or “subdivision” (short subdivisions create a total of four or fewer lots). The pre-application conference form is available here.
A conceptual map of the proposed new lots should accompany the form, along with a fee.
At the pre-application conference, the City will go over the subdividing process, identify “next steps” for the applicant, discuss expected design “issues”, and provide answers to property owner questions.
30. How long does it take to split my lot into two or more lots?
On average, subdivisions and short subdivisions require slightly more than one year to receive preliminary approval with conditions.
A public comment period, public appeal period, and a public hearing (for a subdivision) are included in this timeline.
Time required for the applicant to respond to City requests for information is also included in this time; generally the permit is under review at the City between 120 and 180 days.
Following preliminary approval of the subdivision or short subdivision, the applicant will need to install basic infrastructure for the proposed lots prior to recording the lots for sale or development.
31. How many lots can I create from my property?
The maximum number of lots that can be created is dependent upon four basic items:
Lot yield is calculated by deducting environmentally critical areas and buffers, and public / private streets from the gross lot area. The remaining lot area (i.e. the net area of the lot) is multiplied by the zoned density (e.g. 4 dwelling units per acre) to calculate lot yield.
32. Can I build my garage on my property line?
No, garages (and all buildings) are subject to building setbacks (see response to FAQ #28).
Geology
33. When is a geological report required?
