What do Sammamish homeowners worry about most when getting a permit?
We hear the same three questions on almost every project. Here are straight answers.
How long will this take?
The City does not publish building permit review targets, and it notes that staff changes may temporarily reduce service levels. Fees must be paid before review begins, and reviews after the second round are billed hourly. We send a complete package the first time to keep you to as few rounds as possible.
See how the City works →Will the City send my plans back?
Critical areas, trees, lot standards and the City's inclusionary housing rules can all shape a project, and extra review rounds cost more. We check your lot first, file complete drawings through MyBuildingPermit.com, answer every comment and revise for free until you're approved.
See what the City looks at →How much are permit fees?
The City builds your fee from your project's value, then adds a 65% plan review fee, an energy code fee and a 15% technology fee. By its 2026 formula, a $20,000 remodel comes to about $1,257 before inspection and other fees. We walk you through what applies to you.

What are the building permit requirements in Sammamish?
What the City looks at on a residential permit, and the items that most often shape a project's scope, timeline and cost.
Zoning & lot standards
Setbacks, height, floor area ratio, lot coverage and hardscape limits vary by zoning district. We check your parcel before drawing.
Critical areas & shoreline
Critical areas and their buffers can change what you are allowed to build, and shoreline properties follow their own rules.
Tree removal
Removing a significant tree needs a permit. Significant means 12 inches or larger for deciduous trees and 8 inches for conifers, with limits that depend on lot size.
ADUs & DADUs
Up to two ADUs on a lot with a detached home. A detached ADU can be up to 1,000 sq ft and 24 ft tall, with 5 ft side and rear setbacks.
Inclusionary housing
The City's affordable housing program applies to residential additions and new homes. We check early whether it affects your project.
New impact fees
The City adopted scaled Parks and Transportation impact fees that take effect July 1, 2026, in response to changes in state law.
Trade permits
We prepare the main building permit. Your trades handle their own mechanical, plumbing and electrical permits.
Online and paid in full
Everything is filed on MyBuildingPermit.com, and fees must be paid in full before an application goes to review.

Sammamish projects we've taken to approval
Kitchen & bath remodel
A whole-home refresh with a new kitchen window
This remodel added a kitchen window, relocated the range and a patio door, enlarged the primary shower and expanded a guest bath to fit a new shower. We prepared the drawings, coordinated the structural window calculations and managed the review.
Our role: existing-conditions plans, permit drawings, submittal and review management.
Water damage repair
Repairing a home after a fire sprinkler event
A sprinkler event damaged a home's interior, so the repair replaced flooring, drywall, insulation, cabinets, appliances, bathrooms and doors, with no structural or exterior changes. The City issued the permit 11 days after the application.
Our role: permit application and supporting documents.

Fee rules are as published in the City of Sammamish 2026 Fee Schedule (October 2026). Only the City sets your final fee, which depends on your valuation, scope and any additional permits. City fees are separate from professional fees for drawings and permit management. Source: City of Sammamish Fees (Permits and Applications).
Do I need a building permit in Sammamish?
New or repaired decks need a permit, and so do tub and shower replacements, layout changes and removing significant trees. Sheds up to 200 sq ft on a site without critical areas, retaining walls under 4 feet, non-structural siding and finish work are typically exempt. See the permit tip sheet.

Sammamish permit questions, answered
How long does a Sammamish building permit take?
The City does not publish review targets for building permits, and its Building Division notes that staff changes may temporarily reduce service levels. What it does publish is that fees must be paid in full before an application goes to review, and that reviews beyond the second round are billed hourly, so complete drawings matter. Tree removal applications are screened within two business days and reviewed within five. We submit a complete package and handle every correction for you.
Can I build an ADU or DADU on my Sammamish lot?
Often, yes. The City allows up to two ADUs on a lot with a detached single-family home. A detached ADU can be up to 1,000 square feet and 24 feet tall, with 5 foot side and rear setbacks, and front setbacks from 10 to 20 feet depending on the zone. An attached ADU can be up to 50% of the size of the home or 1,000 square feet, whichever is larger. No additional parking is required when the property already has four or more parking spaces. A feasibility study confirms what your property can support before you pay for full drawings.
Do I need a permit to remove a tree in Sammamish?
Yes, for significant trees. A Tree Removal Permit is required to remove a significant tree, which is a deciduous tree 12 inches or larger in diameter or a conifer 8 inches or larger. Over a 10-year period, the number of trees you may remove depends on your lot size, from 6 trees on lots under a quarter acre to 30 trees on lots over 2 acres. Trees in the street right-of-way need a separate right-of-way permit. We screen for trees as part of every project.
How do I apply for a building permit in Sammamish?
All applications are submitted online at MyBuildingPermit.com, where you upload plans, pay fees and check your permit status. The City's Permit Center states that permits are not issued as a result of a visit or meeting, and project-specific questions go through its Project Guidance Request Form. We prepare and file the application for you.
Why use a permit service instead of my contractor or doing it myself?
Permits are the only thing we do, so we know what the City asks for and how to answer corrections. Our team specializes in permits, a project coordinator manages everything for you, our drawings are done in-house at a fraction of traditional firm cost, and revisions are free until approval. You stay in control, and your contractor can build from the approved permit.
Do you provide the drawings, or just the paperwork?
Both. Our in-house team produces permit drawings and site plans when your project needs them, and manages the full submission and approval process, so you don't need to coordinate with a separate draftsperson.
Do you work in my Sammamish neighborhood?
Yes, we serve every part of Sammamish as well as surrounding cities across King County.
