The short answer
Resolve the distinction between the proposed kitchen work and the existing downstairs use before treating them as one project. Gather plans and permit history, then request a written explanation of the required review path.

Identify the condition being questioned
A finished basement, bedroom, wet bar and separate dwelling are not interchangeable descriptions. Start by documenting the current layout and use accurately. Identify cooking facilities, bathrooms, access, internal connections and the areas shown in existing plans. Have the project professional explain which facts affect the proposed submission rather than choosing the most favorable label.
The kitchen scope also needs precision. Moving it to another room can involve more than cabinet replacement, while a finish change may have a different path. List the actual changes to walls and building systems so the department can distinguish the new work from the older condition.
Assemble a record comparison
Search the SF San Francisco: Permit and Complaint Tracking and obtain relevant older documents through San Francisco: Records Request. Make a simple comparison between the latest documented layout, the current layout and the proposed layout. Highlight differences without assuming that a missing online record conclusively proves illegality. An older plan or inspection document may need a separate request.
Ask the designer to identify the source for every existing-use label on the new drawings. This is especially important if a prior listing or seller's sketch is the only document describing the downstairs. Marketing terminology can be useful background, but it should not silently become the basis for a permit application.
Ask for the dependency in writing
If the department says the downstairs must be addressed first, ask what condition creates that requirement, which application or correction path it expects, and whether the two scopes can be reviewed in a coordinated way. Request clarification when the answer uses an unfamiliar term. The SF San Francisco: Building Inspection Division explains the division's compliance role; it does not establish an automatic outcome for every basement.
A productive question describes facts: the proposed kitchen relocation, the discrepancy in existing plans, and the current use. A less productive question asks how to obtain a permit without anyone considering the downstairs. The first can produce a usable project decision; the second avoids the issue that needs resolution.
Budget alternatives before choosing one
Have the project team compare the proposed kitchen design with a reduced-scope alternative only if that alternative would meet your needs. Include records work, design changes, identified corrections and disruption in each comparison. Do not assume a smaller kitchen project erases an independently existing compliance issue.
Hypothetically, a family may learn that its chosen relocation creates a much broader drawing and correction effort than expected. Its decision could be to phase design work while records are clarified, rather than start demolition and hope approval follows. This is a scheduling choice; it is not a guarantee that a particular reduced scope will be accepted.
Questions for your project meeting
Bring the existing/proposed comparison and ask: Which use is recognized in the records? What evidence is missing? Which drawing sheets need the downstairs shown? What is the required correction or legalization process, if any? Who obtains the answer? What work can responsibly be contracted now, and what remains contingent?
Record answers as confirmed, pending or assumption. Assign a person and next action to each pending item. Before construction, make sure the contractor is pricing the same scope the designer and department understand. A clear boundary at this stage protects the kitchen budget more effectively than an optimistic promise about how quickly an undocumented space can be approved.
A comparison table for the design meeting
Use three rows for the kitchen decision: the current kitchen location, the proposed location and a reduced-scope alternative if one genuinely meets your needs. Under each, list drawing changes, known building-system work, unresolved existing-use questions and the next agency clarification. Do not put a savings number in the alternative column until the project team has defined its scope.
For the downstairs issue, prepare a separate row that stays the same across the options unless the department confirms otherwise. This prevents the team from implying that choosing cheaper cabinets or keeping a wall somehow resolves an unrelated records problem. It also helps the owner see which costs are consequences of the desired design and which arise from the existing property.
At the end of the meeting, name the person responsible for requesting the written agency answer and the information they will provide. Ask the designer to circulate the same comparison to the contractor. The next proposal should state which assumptions remain pending, allowing the owner to authorize useful preparation without mistaking it for approval to construct the entire preferred design.

Is a downstairs room automatically an ADU?
No. Describe its actual facilities, access and use, and obtain the appropriate classification rather than assuming one.
Can a historic online-record gap settle the question?
Not necessarily. Request relevant plans and inspection records before deciding what the gap means.
