Hiring a general contractor in San Francisco is one of the most important decisions you will make for your home. The right contractor delivers quality work on time and on budget. The wrong one causes delays, cost overruns, and stress that lasts long after the project ends.
The good news? You can protect yourself before you sign anything. Asking the right questions during the hiring process reveals everything you need to know about a contractor's experience, transparency, and professionalism.
At Aziz Construction, we believe every homeowner deserves clear answers — not vague promises. This guide gives you 10 essential questions to ask any general contractor in San Francisco before work begins. We also explain what to look for in the answers, so you can compare contractors with confidence.
Are You Licensed and Insured to Work in California?
WHY THIS QUESTION MATTERS
This is the first question you must ask - and you should not move forward until you get a clear, verifiable answer. In California, all general contractors must hold a valid license issued by the California Contractors State License Board (CSLB). If a contractor cannot confirm their license number, walk away immediately.
Licensing is not just a formality. It confirms the contractor has passed competency tests, meets state-mandated requirements, and operates within California's legal framework for construction work. It also gives you legal recourse if something goes wrong.
What Insurance a Legitimate Contractor Carries
General Liability Insurance — covers property damage or injuries that happen during your project
Workers' Compensation Insurance — protects you if a worker gets hurt on your property. Without this, you could be held financially responsible for injuries on your own jobsite
How This Protects You
If a contractor works without proper insurance and a worker gets injured on your property, you — the homeowner — may be liable for medical costs and legal claims. Always ask to see a current Certificate of Insurance before any work begins. A legitimate contractor will provide this without hesitation.
Aziz Construction Trust Angle
Aziz Construction holds a valid California contractor license and carries full general liability and workers' compensation insurance. We provide our license number and insurance certificates upfront — no need to ask twice.
Can You Share Recent Projects and Client References?
WHY THIS QUESTION MATTERS
A contractor's past work is the best predictor of your future experience. Any experienced contractor will have a portfolio of completed projects they are proud to show you. If a contractor hesitates or says their work speaks for itself without showing it — that is a red flag.
When reviewing their portfolio, look for projects similar to yours in scope and complexity. A contractor who specializes in kitchen remodeling may not have the same depth of experience in full home renovations.
What to Ask to See
Before and after photos of kitchen remodeling projects
Before and after photos of bathroom renovations
Examples of full home renovation work
Any projects in San Francisco neighborhoods similar to yours
How to Use Client References
Do not skip the reference call. When you speak with past clients, ask three specific questions: Did the project finish on time? Did the final cost match the estimate? Would you hire them again? The answers to these three questions tell you everything.
Authentic client testimonials — especially from homeowners who had similar projects — give you a realistic picture of what working with this contractor looks like from start to finish.
Ask to see 3–5 recent projects in San Francisco. Local experience matters because San Francisco has unique permitting rules, older housing stock, and site access challenges that contractors unfamiliar with the city routinely underestimate.
What Exactly Is Included in Your Project Estimate?
WHY THIS QUESTION MATTERS
A low estimate is only impressive if it includes everything your project actually requires. Budget surprises are the single most common complaint homeowners have after hiring a contractor and most of them start with an estimate that left out key costs.
A professional contractor provides a detailed written estimate that breaks down every cost category. If you receive a single-number quote with no breakdown, ask for a full itemization before you compare it to other bids.
What a Detailed Estimate Should Include
Labor — hours and rates for each trade involved in your project
Materials — specified by type and quality level, not just a lump sum
Project management fees — supervision, scheduling, and coordination costs
Permit costs — if the contractor handles permits on your behalf
Demolition and site preparation
Cleanup and waste disposal
What to Ask About Exclusions
This is just as important as what is included. Ask the contractor to list specifically what their estimate does not cover. Common exclusions include design and architectural services, structural engineering fees, high-end or upgraded materials, and unforeseen conditions inside walls or floors.
When you know exactly what is excluded, you can budget for those items separately and compare bids on a true apples-to-apples basis.
What a Trustworthy Estimate Always Contains:
A line-by-line cost breakdown (not a single total number)
Material specifications — brand, grade, or quality level
Labor rates and estimated hours per trade
A clear list of what is NOT included
Payment schedule linked to project milestones
Permit costs or a note that they are excluded
Which Pricing Model Do You Use for This Project Type?
WHY THIS QUESTION MATTERS
General contractors in San Francisco use different pricing structures depending on the type and complexity of the project. Understanding which model your contractor uses — and why — helps you predict your total cost and avoid financial surprises mid-project.
Fixed Price Contracts
With a fixed price contract, the contractor sets a total price before work begins. You know exactly what you will pay as long as the project scope stays the same. This model gives you the most budget certainty and is ideal when your plans are fully finalized and materials are already selected.
Time & Materials
With time and materials pricing, you pay for actual labor hours plus the cost of materials used. This model gives you flexibility but makes the final number harder to predict. It works best when the project scope may evolve such as older homes where hidden issues routinely appear once work begins.
Aziz Construction Recommendation
For most defined renovation projects, we recommend fixed price contracts — they protect homeowners and hold us accountable to a clear scope. We use time and materials only when the project genuinely requires flexibility, and we explain exactly why before asking you to agree to it.
What Is the Estimated Timeline for Completing My Project?
WHY THIS QUESTION MATTERS
A clear timeline is not just convenient — it is how you hold a contractor accountable. Before work starts, your contractor should give you a project schedule that shows key milestones, estimated completion dates, and how delays will be communicated and handled.
Typical Project Timelines in San Francisco
Kitchen Remodel: 4 to 8 weeks (longer if permit approval is required)
Bathroom Renovation: 2 to 5 weeks depending on scope and finish level
Full Home Renovation: 3 to 9 months depending on size and complexity
Gut Renovation: 4 to 12+ months for major structural and system work
Factors That Extend Timelines
San Francisco's permitting process is one of the most detailed in California. Permit approval alone can add several weeks to a project timeline, especially for structural, electrical, or plumbing changes. Scope changes during construction — even small ones — also extend timelines and can increase costs.
A contractor who gives you an aggressive timeline without acknowledging these realities is either inexperienced or not being honest. Always ask how they handle permit delays and what their process is for keeping the schedule on track when unexpected issues arise.
What to Watch For: A contractor who guarantees a very short timeline without clearly addressing permits, inspections, and potential site discoveries is setting you up for disappointment. Realistic timelines protect both sides.
Who Will Manage and Supervise My Project Daily on Site?
WHY THIS QUESTION MATTERS
The person who sells you the project is not always the person who builds it. This is one of the most important distinctions to understand when hiring a general contractor. You need to know who will be physically present on your property every day — and who you call when something needs a decision.
What Strong Project Management Looks Like
A dedicated project manager assigned to your job from day one
A site supervisor present during active construction phases
A clear communication structure: who to call, how fast they respond, and how updates are delivered
Weekly or daily progress reports depending on project pace
Why This Directly Affects Your Outcome
Projects without consistent on-site supervision go off-track faster than any other factor. Subcontractors work better when a qualified supervisor is present and accountable. Materials get ordered on time. Problems get caught early before they become expensive. Quality gets checked before work is covered up.
Ask specifically: Will you personally be on site, or will a project manager supervise on your behalf? If it is a project manager — meet them before you sign the contract. Your relationship with that person is what determines how smoothly your project runs.
How Do You Handle Permits and Required Inspections?
WHY THIS QUESTION MATTERS
Permits are not optional in San Francisco. Most renovation and construction work — especially anything involving structural changes, electrical systems, plumbing, or mechanical systems — requires permits from the San Francisco Department of Building Inspection (DBI). Skipping permits creates serious legal and financial risk for homeowners.
What End-to-End Permit Handling Looks Like
The contractor prepares and submits all permit applications on your behalf
They coordinate with San Francisco's Department of Building Inspection
They schedule all required inspections at the correct project phases
They handle any plan corrections or resubmissions if required
All permit costs are disclosed upfront or clearly excluded in the estimate
Why This Matters to You as the Homeowner
Unpermitted work can prevent you from selling your home, trigger fines, or require you to tear out completed work for inspection at your expense. If a contractor suggests skipping permits to save time or money — that is a clear signal to walk away. The savings are never worth the risk.
A contractor who manages the full permit process protects you legally and ensures every phase of work meets California's building standards.
Expert Insight: San Francisco's permit process is more complex than most California cities. Experienced local contractors know which projects require permits, how to submit correctly the first time, and how to keep your timeline on track despite DBI review periods. This local knowledge has real dollar value.
How Do You Handle Changes or Unexpected Issues on Site?
WHY THIS QUESTION MATTERS
Every renovation project faces surprises. Behind old walls in San Francisco homes, you may find outdated wiring, deteriorated plumbing, water damage, or structural issues that were invisible at the start. How your contractor handles these moments determines whether your project stays on track or spirals into chaos.
What a Professional Change Order Process Looks Like
Any change to the original scope triggers a written change order
The change order specifies the exact work added, the cost, and the time impact
You review and approve the change order before any additional work begins
No additional costs appear without your prior written approval
The Right Communication Standard
If unexpected issues arise on site — a contractor stops work, contacts you immediately, explains what they found, and presents your options with honest cost estimates. You make the decision. Work does not resume on the changed scope until you approve it.
Ask your contractor directly: How do you document change orders? Can you show me an example from a past project? A contractor with a clear, professional process will answer this question immediately and with confidence.
What Is Your Payment Schedule and Milestone Structure?
WHY THIS QUESTION MATTERS
How a contractor structures payments tells you a great deal about how they run their business. A professional contractor ties payments to specific project milestones — not arbitrary dates or cash demands. This protects you and ensures the contractor stays motivated to complete each phase on time and to standard.
A Standard, Trustworthy Payment Structure
Initial Deposit (10–20%): Paid at contract signing to confirm the project start date and lock in scheduling
Progress Payment 1 (25–30%): Paid after demolition and rough framing are complete and inspected
Progress Payment 2 (25–30%): Paid after rough electrical, plumbing, and mechanical pass inspection
Progress Payment 3 (15–20%): Paid after drywall, tile, and finish work are substantially complete
Final Payment (10–15%): Paid only after you have walked through the completed project, all punch-list items are resolved, and you are satisfied
What This Structure Means for Your Protection
When payments are tied to milestones, you maintain financial leverage throughout the project. The contractor has a strong incentive to complete each phase correctly before you release the next payment. The final payment — held until you approve the completed work — is your most important protection.
Be cautious of contractors who ask for more than 20–25% upfront, demand large payments before major milestones, or do not link payments to specific deliverables. These are signs of cash flow problems or poor financial management.
What Sets Your Construction Services Apart from Others?
WHY THIS QUESTION MATTERS
This question invites a contractor to speak openly about their values, their process, and what they believe makes them worth your trust. Listen carefully. The best contractors answer this question with specifics — not generic phrases like 'we care about quality.' Specifics reveal real standards.
What Separates a Great Contractor from an Average One
Local San Francisco experience — they know the permit process, the inspectors, the suppliers, and the site conditions that affect Bay Area projects
Transparent pricing — they itemize every cost and disclose every exclusion without being asked
Strong project management — dedicated site supervision, clear timelines, and daily accountability
Quality workmanship — they can point to specific standards they hold themselves to, not just general claims
Responsive communication — they return calls and messages quickly, keep you updated, and never leave you wondering what is happening
