What Interior Designers Do: Understanding Scope of Work Before You Hire

How to avoid the "I thought that was included" nightmare 

The biggest frustration homeowners have when hiring an interior designer? It's not the cost. It's the confusion about what you're actually getting for that cost. 

You hire someone, hand over a deposit, and assume certain things are covered. Then halfway through the project, you realize those things either cost extra or weren't part of the deal at all. Suddenly you're stuck in an awkward conversation about money, wondering why nobody mentioned this upfront. The good news? 

This confusion doesn't happen because designers are sneaky or clients are difficult. It happens because nobody clearly defined the scope of work from the beginning. A scope of work is the written agreement that spells out exactly what you're getting, what you're not getting, how many revisions you have, and what happens if something changes. 

Think of it as your project insurance policy. And if you're wondering “How much does an interior designer cost?”, a clear scope of work is the only way to know what you're actually paying for.

Let's break down the five key components every scope of work should include.

1. Clear Deliverables (What You Can Actually Hold)

When hiring an interior designer, one of the first things to clarify is deliverables (the physical or digital items you receive at the end of the project).

Examples of Deliverables:

• Floor plans with measurements

• Elevations (especially for kitchens, bathrooms, built-ins)

• Material and finish selections (paint, tile, flooring, countertops)

• Sourcing lists with product names, links, item numbers, and prices

• Mood boards or design presentations

• 3D renderings (if included)

💬 What to Ask: "What exactly will I receive at the end of this project? In what format? Can I share these files with my contractor?"

DESIGN TIP:

If a designer can't tell you exactly what deliverables you'll receive, that's a red flag. Part of what interior designers do is provide documentation your contractor can actually use.

2. How Much Does an Interior Designer Cost: Revision Structure

This is where a lot of surprise charges happen. You need to know how many times you can change your mind before it costs you extra.

Common Revision Structures:

• 2 rounds of revisions on the full design

• Unlimited tweaks to one element but limited full-space revisions

• One revision per room

If you're working on a kitchen renovation on a budget, revisions can eat into that budget fast. Some designers charge $150-$300+ per hour for revisions beyond what's included.

💬 What to Ask: "How many revision rounds do I get? What counts as a revision? What happens if I need more than that?"

🚩 Red Flags: No clear revision policy, vague answers, or designers who charge per revision without telling you upfront.

3. What Interior Designers Do: Communication Expectations

Mismatched communication styles cause more frustration than almost anything else. You need to know upfront how communication works.

What to Clarify:

• Meeting structure: How many meetings are included? In-person, virtual, or on-site?

• Day-to-day communication: Email? Project management software? Text? (Most designers hate text messages because they're too confusing to track)

• Contractor communication: Do you or the designer communicate with the contractor?

💬 What to Ask: "What's your preferred method of communication? How quickly can I expect responses? Will you coordinate directly with my contractor, or is that my responsibility?"

DESIGN TIP:

If you hired the contractor separately, don't assume your designer will manage that relationship. Clarify this upfront.

4. Hiring an Interior Designer: What's NOT Included

This is the section that saves homeowners from surprise charges. A good scope of work doesn't just tell you what's included… it tells you what's NOT.

Common Exclusions:

• Contractor coordination (unless specified)

• Shopping or ordering on your behalf

• Installation oversight

• Styling or decorating after installation

• Permit applications or architectural drawings

• Structural engineering

• Ongoing maintenance or touch-ups

If you're trying to figure out how much does an interior designer cost, you need to know what extras might pop up. A $15,000 design package that doesn't include contractor coordination might end up costing you $20,000 once you add those services.

💬 What to Ask: "What's specifically NOT included in this scope? What would require additional fees?"

5. Additional Work and Hourly Rates

Life happens. You decide mid-project to add another bathroom. Or you fall in love with a completely different tile. You need to know how changes are billed.

💬 What to Ask:

• "If I decide to add another room or change direction mid-project, how is that billed?"

• "What's your hourly rate for additional work?"

• "How are change orders handled?"

Knowing the hourly rate upfront prevents sticker shock later. If you're working on a kitchen renovation on a budget and you know additional work is $200/hour, you can make informed decisions.

Hiring an Interior Designer: Here’s What a Good Scope of Work Looks Like

✅ Written in plain language (not confusing legalese)
✅ Itemized deliverables (exactly what you're getting)

✅ Timeline estimates

Questions to Ask Before Signing

• "What's your policy on changes or additions?"

• "Who owns the design files after the project?"

Wrapping It Up: What Interior Designers Do (And What You're Paying For)

Look, I know this feels like a lot of questions to ask. But here's the thing: a good designer will welcome every single one of them. They want you to feel confident, not confused. They want you walking into your project knowing exactly what to expect, when to expect it, and what it's going to cost. 

That's what a clear scope of work does. It takes all the guessing out of the equation so you can focus on the fun part (choosing finishes you love) instead of the stressful part (wondering if you're about to get hit with another invoice). 

When hiring an interior designer, clarity up front means peace of mind throughout the entire process. And honestly? That might be worth more than the design itself.

Your Next Step: Apply the Same Standards to Your Cabinets

Now that you know what questions to ask about scope of work, let's talk about the other place homeowners get burned: cabinets.

Most people spend more time picking out their backsplash than vetting their cabinet order. Then six months later, they're living with drawers that slam into each other and storage that makes no sense for how they actually cook.
