12 Questions to Ask Before Starting a Commercial Renovation

What questions should I ask a contractor before starting a commercial renovation? That's the question every business owner should be asking before they sign anything, and most don't ask nearly enough. The cost overruns, the blown timelines, the surprises that weren't really surprises: many of them trace back to one moment when the owner skipped the hard questions upfront. Framing it as a contractor selection problem is closer to the truth than most owners realize.

This commercial renovation checklist exists to fix that. These 12 questions aren't bureaucratic formalities. They're diagnostic tools. The answers tell you whether you're talking to a contractor who will protect your project or one who will create problems you'll spend months untangling. Use these contractor interview questions accordingly. Experienced Indiana contractors like Ascension Construction actively encourage this kind of conversation before the first meeting wraps up, because projects built on clarity run smoother from day one.

Why Contractors Worth Hiring Welcome These Questions

A contractor who gets defensive when you ask about licensing, insurance certificates, or timeline specifics is telling you something important. They're showing you how they'll behave when real problems surface mid-project. If they're evasive in a sales meeting, expect the same when a permit gets delayed or demolition reveals something unexpected.

Experienced commercial contractors come prepared for these questions. They've done enough projects to know that transparency upfront protects everyone. At Ascension Construction, walking clients through pre-construction expectations before any contracts are signed is standard practice, not because it's required, but because projects built on honest dialogue have better outcomes. They show up to the first meeting with license documentation, an insurance certificate, and a defined process for every item on this list. That's the mindset you're looking for.

What Your Questions Reveal Before You Sign Anything

A contractor's willingness to answer questions thoroughly signals how they'll communicate on the job. If they dodge specifics in the interview, expect the same behavior when you're three months in and a subcontractor is behind schedule. The interview isn't just about getting information. It's about observing how they handle pressure and uncertainty when the stakes are low.

The Difference Between a Salesperson and a Builder

Salespeople give you confidence. Builders give you specifics. The contractor you want can reference actual timelines, name their regular subcontractors, explain their contingency process, and tell you exactly how change orders are priced. If the answers stay vague and polished all the way through the conversation, you're probably talking to someone who needs your signature more than they need your project to succeed.

Questions to Ask Before Hiring a Contractor: Licensing, Bonding, and Insurance

Indiana doesn't issue a single statewide commercial general contractor license. Licensing is handled at the local level, which means requirements vary by city and county. In Indianapolis, commercial contractors must carry a surety bond, pass a written exam, and maintain general liability insurance before they're licensed to work. That doesn't mean every contractor operating in Central Indiana has done this properly. For a concise summary of local requirements and licensing expectations, review resources about Indiana contractor licensing to confirm what documentation you should request.

Ask for documents, not assurances. A contractor who says "yes, we're fully insured" is giving you nothing useful. A contractor who hands you a current certificate of insurance before you finish asking the question is showing you how they operate.

Q1 and Q2: Are You Licensed in Indiana, and Who Pulls the Permits?

Ask the contractor to confirm their local license status for the city or county where your project sits, then ask to see the documentation. For Indianapolis, that means a current commercial contractor license from the city's Department of Business and Neighborhood Services (DBNS). Then ask specifically who pulls the permits for electrical, plumbing, and mechanical work. In most cases, permits are pulled by the licensed contractor or the licensed trade sub performing the work. Some jurisdictions allow the owner to pull the building permit, so verify the local rules for your municipality. Any arrangement that can't be clearly explained is worth pushing on directly. If you want a practical walkthrough of the typical Indianapolis building permit process, consult the local permit guidance so you know where delays commonly occur.

Q3: What Does Your Insurance Cover, and Can I See the Certificate Today?

The practical market standard for commercial renovation work in Indiana is $1 million per occurrence for general liability, with a $2 million aggregate, though limits can vary based on project size and owner requirements. Workers' compensation coverage is required for contractor employees under Indiana law; subcontractors are generally responsible for carrying their own workers' compensation coverage. Confirm how coverage is allocated across everyone on your job site. If the contractor hesitates to produce a current certificate of insurance, or tells you they'll send it over later, stop the conversation there. A gap in coverage puts you, your property, and your business directly at financial risk if something goes wrong on site.

Pre-Construction Questions: Timeline, Permits, and What a Realistic Schedule Looks Like

Business owners often underestimate how long commercial renovations take because they only account for construction time. For a 5,000 to 20,000 square foot office or retail build-out, the realistic end-to-end timeline runs 5 to 11 months when you factor in pre-construction, permitting, and closeout. Construction itself typically runs 3 to 6 months for that size of project. Pre-construction adds another 2 to 5 months before a hammer swings.

In Indianapolis, commercial tenant improvement permits go through an initial plan review cycle of roughly 15 to 20 business days through the DBNS. If corrections are required, each subsequent review adds another 5 to 10 business days. Most projects go through at least two review cycles, which means permitting alone can consume four to six weeks before construction begins. Any contractor who glosses over this isn't planning your project honestly.

Q4 and Q5: What's the Full Timeline from Kickoff to Certificate of Occupancy?

Ask for phase-by-phase specifics, not a single number. Pre-construction and permitting: how long? Demolition and MEP rough-in: when does that start and finish? Finishes and closeout: what's the target date? A contractor who can walk you through each phase with real time ranges has actually thought through your project. One who gives you a single number and moves on hasn't.

Q6: How Do You Handle Delays from Permits, Hidden Conditions, or Material Lead Times?

Every experienced commercial contractor has had a permit delayed, opened a wall and found asbestos, or waited on long-lead materials that pushed the schedule. Ask them to walk you through their contingency process. How do they communicate changes? What's your role when a fast decision is needed? A contractor who has a real answer here has built it from experience. One who says "we'll cross that bridge when we come to it" is telling you exactly how prepared they are.

Budget Structure, Change Orders, and Contract Protections

Change orders are where most commercial renovation budgets fall apart. They're also where trust either holds or breaks. Design errors, hidden site conditions, owner-requested scope changes, and code updates are the primary drivers. How your contractor handles them financially and procedurally will determine whether your final cost resembles your original budget. For an industry perspective on how change orders are processed and priced, review guidance on change orders in construction so you know what conventions to expect.

For commercial renovations in the Midwest, a common owner contingency recommendation runs 10% to 15% of the total project cost. A well-priced project with complete drawings and known conditions can hold closer to 10%. Older buildings or complex scopes warrant 15% or more. Know this number before you walk into a contractor interview. If you're unsure what contingency is reasonable for your project type, industry analyses of recommended contingency by project type can help calibrate expectations.

Q7 and Q8: How Is the Contract Structured, and How Do You Price Change Orders?

Ask how the contract is structured: lump sum, unit pricing, or time and materials. Each has legitimate uses, but you need to understand which one applies to your project and why. Then ask specifically what markup percentage they apply to change orders. Industry practice generally runs 10% to 15% for overhead and 5% to 10% for profit, though actual markups vary by contractor and project type. That should be spelled out in the contract language, not negotiated verbally after a change order lands on your desk.  A contractor who can't explain their change order pricing clearly is creating budget exposure for you before the project even starts.  For a checklist of the key contract clauses every construction contract should include, use legal guidance to ensure your contract contains the protections you need.

Q9 and Q10: What Contingency Do You Recommend, and What Happens If the Project Runs Over Schedule?

Ask whether the contingency is built into the base bid or held separately, and what percentage they recommend for your specific project type. Then ask about liquidated damages. If they miss the completion date, what does the contract say? Get specific language here, not general reassurance. Also require that lien waivers from subcontractors and suppliers are tied to each payment milestone.  Final payment should not be released until all lien waivers are in hand.  If the contractor hasn't mentioned this already, ask why.

Communication, Subcontractors, and Who Runs Your Job Site

Money issues get attention, but communication failures cause just as much damage. Who is your single point of contact? How often do you get written updates? What's the process when something changes mid-project? These questions reveal whether the contractor runs a professional operation or manages each project through informal calls and best-guess coordination.

Q11: Who Is My Point of Contact, and How Do You Communicate During Construction?

Ask for specifics: weekly site meetings, written progress reports, and a defined process for communicating change orders before work begins, not after. A contractor with a documented communication process has invested in professional maturity. A contractor who says "you can call me anytime" hasn't built a system. They've built a dependency on one person staying available.

Q12: Who Are Your Subcontractors, and How Do You Vet Them?

Subcontractor quality is where build quality is won or lost on most commercial projects. Ask whether the contractor uses the same subs regularly or pulls from a general pool on each job. Ask if subs carry their own licenses and insurance independently. For healthcare or specialty renovations, ask whether the subs have relevant experience with that project type.  The general contractor is accountable for subcontractor performance.  They should be able to answer these questions without hesitation, because a contractor who doesn't know their subs well doesn't control their project well.

How to Read the Answers and Make the Final Call

After running through this commercial build-out questions checklist, you'll have a clear picture of who you're actually talking to. The answers will separate contractors who are prepared from those who are performing. Use that information deliberately.

Red Flags That Tell You to Keep Looking

Watch for these specific warning signs during the conversation:

• No written contract offered, or resistance to putting change order terms in writing

• Vague or unverifiable insurance coverage, or a promise to send the certificate "later"

• Pressure to sign quickly to lock in pricing or availability

• "We'll figure it out as we go" when asked about contingency or permit delays

• No named subcontractors and no clear answer on how subs are vetted

Any one of these signals a problem. More than one means you keep looking.

What the Right Answer Sounds Like

A confident, experienced commercial contractor answers these questions calmly, specifically, and without deflection. They reference real timelines, real subcontractor names, and real processes. They don't oversell and they don't hedge. Their answers are backed by documented systems, not by personality or charm. When you ask about insurance, the certificate is in front of you. When you ask about change orders, they walk you through their contract language. That's the contractor who will protect your project when things get complicated.
