You’re reviewing the drawings for your addition and you see a detail that doesn’t make sense. The electrical plan shows a circuit breaker box in two different locations. You could ignore it and hope it resolves itself. Or you could ask now, before the work starts. That’s what an RFI is for.

Why RFIs Matter More Than You Think

I’ve managed enough projects to know that the smallest unclear detail can become expensive later. A misunderstanding about material specs, dimensions, or installation method doesn’t stay small. It becomes a change order—a written amendment to your contract that adjusts scope or price. And by then, the contractor has already started working based on his interpretation, not yours.

An RFI is your chance to ask questions before work begins. It creates a written record of what was unclear and what the answer was. That record protects both you and your contractor. It prevents arguments about “who said what” later.

Most homeowners wait too long to ask. They hope things will become clear once work starts. That almost never happens. The time to ask is now, when changes are still simple and inexpensive.

What an RFI Actually Is

An RFI is a formal request, not a casual question. You could ask your contractor in a text or phone call, but an RFI is written and dated. It goes to the architect and the contractor. Everyone sees the same question and the same answer.

Your contract probably already defines how RFIs work. It will say who submits them, who answers them, and how long the answer should take. Read your contract’s section on RFIs before you write your first one. Most standard contracts allow 5-7 business days for an answer.

An RFI is not a complaint. It’s not an accusation that something is wrong. It’s a neutral question asking for clarification. Keep that tone throughout.

Step 1: Identify What You’re Actually Asking

The biggest mistake is writing an RFI that’s too vague. “This doesn’t look right” is not useful. The contractor cannot answer it because he doesn’t know what specifically you’re questioning.

• Reread the plans or specification section that confuses you
• Identify the exact detail, dimension, material, or location in question
• Write down what you see in one document and what you see elsewhere that contradicts it
• Ask yourself: “What specific thing do I need the contractor to tell me?”
• Do not write the RFI until you can answer that question in one sentence

Example: Instead of “The bathroom tile looks confusing,” write “The floor plan shows 2×2 ceramic tile, but the detail section shows 3×6 porcelain tile. Which is correct?” The contractor knows exactly what to answer.

Step 2: Reference the Exact Location in the Documents

Your contractor and architect have dozens of drawings. You need to tell them exactly where to look. Vague references waste everyone’s time.

• Name the specific drawing or specification section (example: “Sheet A4.2, Kitchen Elevation”)
• Include the drawing number, date, and revision if available
• Reference the exact detail number or callout if there is one
• For specifications, cite the CSI division number—the standard numbering system for construction specs—and the section name (example: “CSI Division 09 – Finishes, Section 09 29 00, Gypsum Board”)
• If the conflict is between two documents, reference both
• Take a screenshot or scan the relevant pages and attach them

Example: “Sheet A2.1 – Floor Plan, revision dated March 15, shows the kitchen island at 36 inches wide. Sheet A4.3 – Kitchen Elevation shows the island at 42 inches wide. Which dimension should the contractor build to?”

Step 3: Describe What You See, Not What You Think

Stick to facts. Don’t interpret or guess at what something means. Let the contractor and architect answer the question based on the actual documents.

• State exactly what the plan shows (example: “The detail shows the window trim installed flush to the exterior sheathing”)
• State what the specification says (example: “The spec requires a 1-inch rain screen gap behind all exterior cladding”)
• Do not assume you know what’s wrong
• Do not suggest a solution or correction
• Do not accuse anyone of making an error
• Use neutral language: “the drawing shows” not “the drawing is wrong”

Example: “The standard detail for exterior wall assembly shows 6 inches of stone veneer. The opening detail for the window shows stone veneer extending 2 inches on both sides of the window frame. For a 36-inch window, this creates a conflict. Please clarify the intended veneer width at window openings.” This approach respects the professional work already done while asking for clarification.

Step 4: Explain Why You’re Asking

A one-sentence explanation of why this matters makes the RFI faster to answer and shows you’re serious, not nitpicking.

• Explain the practical impact (example: “This affects the rough opening size for the HVAC ductwork”)
• Note if the unclear detail affects timing or sequencing (example: “The contractor needs to know this before framing the wall”)
• Mention cost implications only if they’re real (example: “The material choice affects the budget”)
• Keep this brief—one or two sentences maximum
• Frame it neutrally: “to move forward” not “to avoid problems”

Example: “This affects the framing timeline because the contractor needs to know the exact opening size before he builds the header.”

Step 5: Ask a Clear Question, Not Multiple Questions

One RFI should have one main question. If you have multiple unrelated questions, write multiple RFIs. This keeps each one focused and easier to answer.

• End with a direct question that requires a specific answer
• Avoid compound questions like “Should the tile be 2×2 or 3×6, and if 3×6, should it be porcelain or ceramic?”
• Ask “Which dimension should the contractor build to?” not “Is there an error here?”
• Request a specific answer format if it helps (example: “Please provide a marked-up drawing showing the correct location”)
• Do not ask for design advice or opinions

Example: “The plans and spec disagree on the tile size. Please confirm: Is the kitchen floor tile 2×2 ceramic or 3×6 porcelain?” The contractor knows exactly what answer you need.

Step 6: Attach Relevant Documentation

Screenshots and marked-up pages save time and reduce the chance of misunderstanding. The contractor doesn’t have to dig through documents to understand your question.

• Scan or screenshot the exact pages you’re referencing
• Circle, highlight, or arrow the specific detail in question
• If there are two conflicting details, attach both pages marked side-by-side
• Use a PDF annotation tool or mark-up app to highlight what you’re asking about
• Attach the file to your RFI
• Keep file sizes reasonable—under 10 MB total

Example: Attach Sheet A2.1 with the island width circled on the floor plan, and Sheet A4.3 with the different width highlighted on the elevation. The contradiction is now impossible to miss.

Step 7: Submit It Formally Through the Right Channel

Your contract defines how RFIs are submitted. Follow that process. If your contract doesn’t say, ask your contractor or architect how they want to receive RFIs before you send your first one.

• Use email if that’s what your contract requires, and send it to all parties listed in the contract
• If your project uses a construction management platform, submit it through that platform
• Include “RFI” in the subject line with a brief description
• Number your RFIs in sequence (RFI #1, RFI #2) for easy reference
• Date it and note the date it was submitted
• Keep a record of every RFI you submit and every answer you receive
• Do not submit RFIs in texts, phone calls, or casual emails unless the contract explicitly allows it

Example: Subject line: “RFI #3 – Kitchen Island Dimension Conflict.” Include the date submitted and send it to the GC, the architect, and anyone else your contract specifies.

What to Watch For

• An answer that doesn’t actually answer your question—push back and ask for clarification
• An RFI that comes back marked “See the plans” without additional explanation—this is not a useful answer, request a specific clarification
• A delayed answer that arrives days after the contractor has already started the work—this is a red flag and may indicate a change order is coming
• An answer that requires a change order to implement—if the clarification changes scope or cost, that becomes a separate change order document
• An RFI that contradicts your contract—if the answer conflicts with what your contract says, the contract usually wins, but ask your architect to confirm
• Multiple similar RFIs getting different answers—this suggests confusion in the design and may require an architect meeting to resolve

Questions to Ask Your Contractor or Architect

Before you start submitting RFIs, make sure you understand the process. These questions will clarify how your project handles them.

• How should I submit RFIs—email, a specific platform, or printed form?
• Who do I send RFIs to, and who else will see them?
• How long should I expect to wait for an answer?
• If I don’t get an answer in that time, what’s my next step?
• If an RFI answer requires a change to the scope or cost, how does that become a change order?
• Should I number my RFIs myself, or will you do it?
• If the plans are unclear on multiple related details, should I ask them all in one RFI or submit separate ones?
• What happens if the architect and contractor disagree on the RFI answer?
• Can I submit RFIs before work starts on that part of the project, or only during construction?

The Bottom Line

An RFI is your tool to get clarity before work starts. Write it clearly, reference exactly what you’re asking about, and keep it focused on one question. A well-written RFI takes the contractor five minutes to answer. A vague one takes an hour, or doesn’t get answered at all. Start submitting RFIs the moment you see something unclear in the plans or specifications. Don’t wait for construction to begin.
