For a rented home, confirm who can authorize alterations. In a shared building, ask about access and work rules. A citywide construction period does not establish the age, condition or safety requirements of an individual home; check the property records and the specific project.
Choose the work you need to plan
Use the project guides to identify the work, then check listings against the property’s city and state. A guide link does not mean a provider is available for every task or address.

Seattle repair planning: the local decisions
Decide whether the request is a finish repair or a building change
Keep hardware adjustment, product assembly and surface repairs distinct from a change to a wall, deck or building system. Give the property and unit address, where the work sits and what will be different when it is finished. Photographs can explain the request, but they do not replace an assessment of concealed or structural conditions.
For a shared building, record who can authorize access and work on common components. If assessment reveals a larger change than the original repair, update the scope before agreeing the next step. That gives the business a specific proposal to accept rather than an open-ended instruction to fix everything nearby.
Ask SDCI before relying on an STFI shortcut
SDCI’s Tip 316 describes a subject-to-field-inspection process for qualifying simple projects. The Tip page also warns that guidance may lag recent regulatory changes and directs current code and application questions to staff. Treat the page as a starting point for inquiry, rather than a guarantee of eligibility.
The official Seattle Services Portal help, updated in June 2026, explains creating a pre-application before an STFI application. STFI is a permit process, not the absence of an application. Follow current SDCI instructions for the actual property and work instead of relying on an assumed cost limit or approval time.
Keep record, inspection and finish responsibilities visible
Ask who will prepare documents if required, respond to review comments, arrange inspections and complete finishes after the accepted repair. Keep assessment and any specialist design or trade work explicit. The final price should make clear which stage it covers.
Read each business’s published area literally. A Seattle listing and an Eastside area description are not interchangeable promises to serve every address. Use the task links to define the component, then confirm address coverage and the specific work directly with a business whose source information fits the request.

Questions for Seattle project planning
Does a Seattle subject-to-field-inspection project skip the permit application?
No. The official Seattle Services Portal instructions describe a pre-application followed by the STFI application and its required information. SDCI should confirm whether the proposed project qualifies for that process.
Why ask SDCI about current rules even when Tip 316 describes a project?
The Tip page explicitly warns that guidance may not reflect recent regulations. Use its current-question route for the specific address and proposal, particularly before relying on a remembered eligibility rule.
