Construction Warning Signs: A San Francisco Homeowner’s Reference Guide
Most warning sign guides focus on the obvious: unlicensed operators, cash-only demands, a truck with no logo. Those are real, but they are also rare enough that most San Francisco homeowners will never encounter them. The California Contractors State License Board receives tens of thousands of complaints each year, and the most common involve payment disputes and incomplete work. Not unlicensed contractors. That tells us something important: the problem is not who homeowners hire. It is what they agreed to in writing before the work began. This guide names the subtler patterns that show up in real bids, real contracts, and real conversations across San Francisco, so you can recognize them before they cost you.
Quick Answer
The warning signs that matter most in San Francisco are vague material specifications in bids, deposit requests above California’s legal limit of 10% or $1,000 (whichever is less), payment schedules that front-load money before work is complete, any resistance to pulling permits, and a refusal to put warranty terms in writing. A contractor who is specific about materials, comfortable with permits, and willing to name a written warranty period with a response time is signaling that the job will be governed by a contract, not a conversation.

The Vague Specification: Why “Tile of Your Choice” Is a Warning
A bathroom bid that reads “tile of your choice” is not generous. It is a blank check. Here is what happens with a line item like that: the contractor prices the job assuming a $3 per square foot ceramic tile, and when you select a $9 per square foot porcelain from a showroom on Third Street, the change order arrives. Same with “standard cabinets” on a kitchen bid. What does standard mean? A kitchen remodeling project in San Francisco with KraftMaid or Wellborn cabinets named in the contract is a project where you can look up exactly what you are getting, including the door style, the hinge hardware, and the finish. A project with “standard cabinets” in the line item is a project where a decision gets made later, often when the crew is already on site and the easiest path is whatever the supplier has in stock that week.
Here is how to spot a vague specification in a real bid:
- The adjective does the work. “Quality fixtures,” “premium flooring,” “good-grade lumber.” These words mean nothing in a contract. A real specification names a brand or a measurable standard: Kohler or Moen fixtures, 3/4-inch plywood subfloor, James Hardie siding with a specific profile and color code.
- No allowances are stated. A legitimate contract may include an allowance for something like tile, but it will state a dollar figure: “$2,500 allowance for wall tile at $8 per square foot, homeowner selection required by [date].” That is a decision framed inside a budget. “Tile of your choice” is a decision deferred without a budget.
- The bid is suspiciously short. A full bathroom remodel involves waterproofing, plumbing, electrical, tile, fixtures, and finish work. If the entire bid fits on one page, specifications are being omitted. Some projects in a San Francisco Victorian or a 1940s Marina District home involve unknown conditions behind the walls, and a thoughtful bid names the unknowns and explains how they will be handled.
In our experience, the families who get the outcome they wanted are the families whose contracts name the products. That is why every bathroom remodeling project in San Francisco we write includes brand-specific fixtures and finishes in the written price before any work starts. No “to be determined later.” The price is the price, and the product is the product.
The California Deposit Law: What a Legal Deposit Actually Looks Like
California Business and Professions Code Section 7159 is specific: a contractor cannot ask for a down payment of more than 10% of the total project price or $1,000, whichever is less. For a $52,000 kitchen remodel, that is $1,000, not $5,200. For a $9,000 bathroom refresh, that is $900. A contractor who asks for 30%, 40%, or 50% up front is not just aggressive. They are asking you to break state law along with them.
Why this matters for San Francisco homeowners specifically: real estate here is expensive, remodels are expensive, and the financial pressure to just get the project moving is real. A contractor who asks for a $15,000 deposit on a $60,000 job knows that once you hand over that check, you are psychologically committed and financially exposed. If the work stalls, you are now negotiating from a position of loss. The legal 10% or $1,000 cap exists precisely to keep the homeowner’s risk proportional to the contractor’s risk.
Here is what to watch for:
- A request for more than $1,000 or 10% down. This is the single clearest warning sign in a contractor conversation. There is no legitimate reason a licensed California contractor needs to violate the deposit cap.
- A “materials deposit” that pushes the down payment above the cap. Some contractors will structure the contract as a small deposit plus a separate “materials order” payment. That is still a down payment, and it still violates the law.
- Pressure to pay in cash or by wire. Checks and credit cards create a paper trail. Contractors who want payment methods with no trail often have a reason.
- Deposit requested before a written contract exists. No check should change hands until the scope, price, schedule, and specifications are in writing and signed. In San Francisco, where multi-month remodels are common, the written contract is the only thing that protects you through the unexpected.
Every general contracting project in San Francisco we manage starts with a written price, a deposit that complies with California law, and a schedule that ties payments to completed milestones. Not to promises about milestones. To milestones you can see with your own eyes.
Payment Schedules That Shift Risk to the Homeowner
The deposit cap matters, but the rest of the payment schedule matters just as much. Here is the pattern that causes the most harm: a contract that collects 50% to 70% of the total price before the work is halfway complete. The homeowner is now in a position where the contractor has most of the money, and the homeowner has most of the leverage removed. If the work slows, stalls, or drags on for months, the homeowner has little recourse beyond a complaint that will take months itself to resolve.
A legitimate payment schedule protects both parties. It ties each payment to a specific, verifiable milestone, and it never lets the money get ahead of the work. Here is what a sane structure looks like:
- Deposit: 10% or $1,000, whichever is less, at contract signing.
- Progress payments: scheduled at defined milestones, each representing real completed work. Demolition complete and site cleaned. Rough plumbing and electrical inspected. Drywall hung and taped. Cabinets set. Tile complete. Each payment is 15% to 25% of the total, not half up front.
- Final payment: held until the punch list is complete, the final inspection has passed, and the homeowner has walked the space. A contractor who insists on final payment before the walkthrough is asking you to surrender your last piece of leverage.
Here is the second pattern to watch: a schedule that is front-loaded but dressed up in milestone language. “50% due after demolition” is a front-loaded schedule, even though demolition is a real milestone. Demolition is 15% of the work on most Elmstead Remodeling San Francisco home projects, not half of it. The question to ask is simple: does each payment reflect the amount of work actually completed at that point? If the numbers do not line up, the schedule is designed to shift risk from the contractor to you.
A written price before any work starts is the foundation, but a payment schedule that tracks progress is the frame that holds everything else up. Both should be in the contract, and both should be specific enough that a third party could look at the document and know exactly what happens when.
Why Permit Resistance Is a Serious Concern in San Francisco
Here is a scenario we hear regularly: a San Francisco homeowner wants to finish a basement or convert a garage into living space, and a contractor suggests skipping the permit because “it will slow things down” or “the city will just make it more expensive.” What that contractor is really saying is that they want to do work that would not pass inspection, or they want to avoid the cost and time of compliance, or both. None of those are reasons that benefit the homeowner.
San Francisco is one of the most regulated construction markets in the country. The Department of Building Inspection enforces seismic retrofit requirements, energy efficiency standards, and detailed rules about what can and cannot be done to a building without review. Skipping permits is not a shortcut. It is a transfer of risk:
- At sale: unpermitted work must be disclosed on the seller’s disclosure documents. Buyers in San Francisco routinely require permits for any significant work, and lenders may refuse to finance a home with unpermitted additions or conversions. The work you “saved” money on becomes a liability when you sell.
- Insurance: if an unpermitted gas line fails, an unpermitted electrical circuit shorts, or an unpermitted structural change contributes to damage, your homeowner’s insurance carrier can deny the claim. The policy language typically excludes work that was not properly permitted and inspected.
- Liability: if unpermitted work fails and someone is hurt, the homeowner is liable. The contractor who told you to skip the permit will point to the contract that says permits were the homeowner’s responsibility, or they will simply be gone.
- Code compliance: San Francisco has strict seismic provisions for a reason. Work done without inspection may not meet current code, and you will not find out until something fails or until you try to sell.
A contractor who pulls permits, schedules inspections, and stands with you when the inspector walks through is carrying a share of the responsibility. That is the contractor you want. It takes longer and costs more, which is why the contractor who suggests skipping permits sounds so appealing in the moment. The appeal lasts until the first problem.
Occupied-Home Warning Signs for Families with Children and Pets
Most remodeling in San Francisco happens in homes that are fully occupied. The family is living through the work. That means the warning signs to watch for are not just about the contract. They are about how the contractor treats the home as a place where children sleep and pets walk and life continues while construction happens.
Here is what we watch for, and what you should watch for, in the first week of an occupied-home project:
- Dust containment that is not sealed at the end of each day. A plastic sheet hung loosely in a doorway is not containment. Proper dust control means zippered barriers, floor protection, and a work zone that is actually sealed off from the living space. If you can see a film of dust on the dining table at 6 p.m., the containment has failed. For families with young children, dust is not just an annoyance; a remodel in a pre-1978 San Francisco home can disturb lead paint, which is a serious health concern for children under six.
- No posted quiet hours. The contractor should be able to tell you, in writing, when loud work will happen and when the work zone will be quiet. Most professional crews in San Francisco start early, but families with nap schedules and school-age children need to know when the saws stop. A contractor who cannot answer the question “when can my toddler nap” has not thought about your family.
- Tools and materials stored in unsecured areas. A sharp chisel left on a hallway floor, a cordless drill on the kitchen counter, an open box of screws at toddler height. These are signs of a crew that is not thinking about the people living in the house. Tools should be stored in the work zone, in locked cases or closed tool bags, at the end of every day.
- Entry and exit protocols that are loose. Who comes in the front door, and when? Are shoe covers used at the door? Is the door locked when the crew leaves? Families with children need to know exactly who is in the house at any given time, and the answer should be “background-checked, uniformed technicians who identify themselves and follow a written entry protocol.”
- No plan for the pets. A dog that bolts out an open door, a cat that panics at the sound of a hammer drill. A contractor who has done occupied-home work in San Francisco will ask about pets before the first day, not after the gate is left open.
The Cedarwell Care Promise that governs every one of our projects exists because these details are not optional for families. Shoe covers and drop cloths inside the house, a written price before the work starts, a photo of the clean-up before the crew leaves, quiet tools during family rest hours where possible, and pet-safe product choices where there is a choice. Those are not add-ons. They are the baseline, and they are written into the contract.
What a Legitimate Warranty Looks Like in Writing
“We stand behind our work.” Every contractor says this, and it means nothing. A verbal promise is unenforceable, and more importantly, it does not tell you what will actually happen when something goes wrong. Will they come back in two days? Two weeks? Two months? Will they cover the cost of materials that failed, or only the labor to replace them? Who decides whether something was “done right”?
A legitimate warranty answers those questions in writing. Here is what to look for:
- A named period. “One year,” “two years,” “five years on the waterproofing.” Not “as long as you own the home” and not a vague “we guarantee our work.” The period should be specific enough that you can mark the end date on a calendar.
- A response time. “We will respond to any warranty claim within five business days” is a commitment. “We’ll take care of you” is not. The response time is the difference between a warranty and a hope.
- Scope. What is covered, and what is excluded? A written warranty should distinguish between workmanship defects, which the contractor covers, and normal wear and tear or homeowner misuse, which they do not. And the exclusions should be stated, not discovered later.
- Transferability. If you sell the home, does the warranty travel? In a city where homes change hands every seven to ten years on average, a transferable warranty is worth more than one that evaporates at closing.
- Integration with manufacturer warranties. Products like James Hardie siding and GAF roofing carry their own lengthy manufacturer warranties. A good contract identifies those warranties by name and explains how they interact with the contractor’s workmanship warranty.
Our 365-Day Done Right Promise is the warranty we write into every contract: if it is not done right after the job is complete, we make it right. It is not the longest warranty in the industry, and we will tell you that. But it is specific, it is written, and it has a response time. A warranty you can read is a warranty you can hold someone to.

AfterHow to Compare Two Bids Side by Side
Most San Francisco homeowners get two or three bids for a significant remodeling project, and the comparison usually comes down to one number: the bottom line. That is a mistake, because the bid is a document, and the documents are rarely equivalent. Here is a step-by-step method for comparing two bids that look similar in price but are not similar in substance:
- Lay the scope lines beside each other. Does Bid A include demolition, hauling, and disposal? Does Bid B? Does Bid A include the final clean-up, or is that a separate line item? A bid that is $4,000 cheaper but omits the hauling is not cheaper.
- Check the specifications for every product line. “Kohler sink, Moen faucet, 3/4-inch plywood” against “standard sink, quality faucet, appropriate substrate.” The first bid is priced; the second is estimated. Over the course of a kitchen remodel, the difference can be thousands of dollars in change orders.
- Compare the payment schedules. A legal deposit, milestone payments that track progress, and a final payment held for the walkthrough. If one bid has a 50% midpoint payment and the other has a 35% midpoint payment for the same milestone, the second bid is carrying more of the risk for you.
- Look at the permit line. Both bids should include the cost of permits and the cost of inspections if required for the scope. A bid that omits permits either assumes they are not needed, which may be wrong, or plans to add them later, which is a change order in waiting.
- Read the warranty language. One page on the back of the contract with a written period and response time, or a handshake. This one is self-explanatory.
- Ask the “who is in my home” question. Background checks, uniforms, subcontractor vetting, a named project lead. A bid from a contractor who cannot answer “who will be on site” is a bid from a contractor who has not thought about the families living through the work.
We tell every homeowner who is comparing bids to put the two documents side by side and read them before comparing the numbers. The cheapest bid is often the most expensive one in the end, because the omissions that made it cheap get added back as change orders once the work is underway and the homeowner has lost the ability to walk away.
Questions to Ask Before Signing Anything
A written contract is the only thing that protects you, but the conversations before the contract tell you a lot about what kind of document you are about to sign. Here are the questions we recommend every San Francisco homeowner ask, and the answers a legitimate contractor will give:
- “Can I see your written price before any work starts?” A contractor who hesitates, suggests a time-and-materials arrangement, or says “we’ll figure out the details as we go” is telling you the price will grow. The answer you want is a yes, and a price in writing.
- “Will you pull permits for this work?” In San Francisco, a significant remodel almost always requires permits. The contractor should say yes and should be able to name the specific permits for your scope. A hesitation here is a red flag.
- “What is your warranty, and can I see it in writing?” A named period, a response time, a defined scope. If the answer is “we stand behind our work,” ask again. The second ask is where you learn whether the warranty is a document or a slogan.
- “How do you protect the rest of the house?” Shoe covers and drop cloths, dust barriers, sealed work zones. For families with children and pets, this answer should be detailed and immediate, not improvised.
- “Who will be in my home, and how do you verify them?” Background checks, uniforms, a named lead on the project. The contractor should be able to tell you exactly who walks through the door.
- “How do you handle the unexpected?” In a San Francisco Victorian, the unexpected is routine: knob-and-tube wiring, rotted sills, non-conforming plumbing. A legitimate contractor describes a change order process that puts the new price in writing before the new work begins, not after.
These questions are not adversarial. A good contractor will welcome them, because they signal a homeowner who will hold up their end of the contract and a project that will run on documents, not impressions. A contractor who bristles at these questions is telling you something important about how the project will feel.
Common Mistakes to Avoid
- Signing a contract with “to be determined” anywhere in the specifications. Every TBD is a future change order. If the product has not been selected, the contract should include a specific allowance with a dollar figure and a selection deadline.
- Paying a deposit above the California legal limit. 10% or $1,000, whichever is less. If a contractor asks for more, that alone is reason to walk away, regardless of how well everything else has gone.
- Letting a verbal promise stand in for a written warranty. If it is not in the contract, it does not exist. Verbal assurances about quality, timing, or warranty coverage are worth exactly zero in a dispute.
- Skipping permits to save time or money. In San Francisco, unpermitted work is a disclosure at sale, a potential insurance exclusion, and a liability if something fails. The savings are a loan against a future problem.
- Comparing bids by bottom-line price alone. Two bids can differ by $5,000, but if one omits the permit, the final clean, or the waterproofing membrane, it is not cheaper. Read the scope before you read the total.
- Ignoring early warning signs in the first week. Loose dust containment, tools left out, no quiet hours, a crew that leaves the door unlocked. These are not growing pains. They are how the rest of the project will go.
- Feeling too awkward to ask the hard questions before signing. The contractor relationship is a business relationship with hundreds of thousands of dollars and months of your life on the line. Ask. The right contractor will answer.
When to Call a Professional
If you are looking at a bid that has vague specifications, a deposit request above the legal cap, a front-loaded payment schedule, or any resistance to permits, that is a sign to stop and get another opinion. If you are planning a bathroom, kitchen, or general contracting project in San Francisco and want a written price, named-brand materials, and a contract that answers every one of the questions in this guide, that is also a sign to call. Elmstead Remodeling San Francisco offers free estimates in San Francisco. Call (831) 480-4497. We will walk you through the scope, the price, the permits, and the warranty before you sign anything, and the price we give you in writing is the price you will pay.
Frequently Asked Questions
The biggest warning sign is a bid with vague specifications: “tile of your choice,” “standard cabinets,” “quality fixtures.” That language means the contractor has priced the cheapest option and plans to charge change orders when you select something specific. In San Francisco, where remodel costs run higher than the national average, those change orders can be substantial. Call (831) 480-4497 to talk through what a properly specified bid looks like.
California law caps the down payment on a home improvement contract at 10% of the total project price or $1,000, whichever is less. For most San Francisco remodels, that means $1,000. A contractor who asks for more is asking you to violate state law, which should end the conversation.
You can, and it is a serious mistake. Unpermitted work must be disclosed when you sell, can void your homeowner’s insurance on the affected space, and leaves you liable if something fails. San Francisco has some of the strictest seismic and energy codes in the country, and work done without inspection may not meet them. A legitimate contractor pulls permits and stands with you through the inspections.
A written warranty should include a named period, a response time, a defined scope of coverage, and clear exclusions. “We stand behind our work” is not a warranty. Our 365-Day Done Right Promise names a period and a commitment: if it is not done right after the job is complete, we make it right. Call (831) 480-4497 and we will show you the warranty language before you sign.
Choose a contractor who has a written protocol for occupied homes: sealed dust barriers, shoe covers and drop cloths, posted quiet hours, secure tool storage, and pet-safe product choices where available. Ask about these specifics before signing. A contractor who has not thought about a toddler’s nap schedule or a dog that bolts has not done much occupied-home work.
Payment disputes and incomplete work are among the most common complaints filed with the California Contractors State License Board. That points to the real problem: vague contracts and front-loaded payment schedules, not unlicensed operators. The written contract, with specific specifications and milestone payments, is the homeowner’s best protection.
The Bottom Line
The contractors who harm San Francisco homeowners are not usually the obvious ones. They have trucks with logos, business cards, and confident handshakes. The harm comes from what is missing: specifications that name actual products, permits that keep the work legal and insurable, payment schedules that do not put most of the money in the contractor’s pocket before the work is complete, and warranties that exist on paper instead of in conversation. If you are planning a remodel, get the price in writing, get the products named, get the permit question answered, and get the warranty in the contract. A good contractor will not resist any of it. Call (831) 480-4497 for a free estimate, and we will show you what a properly built bid looks like before you sign anything.
