Quick Answer: The two things homeowners compare, portfolio photos and price per square foot, are the two least predictive things available. What actually predicts a good San Jose remodel is whether the contractor priced your specific house (panel capacity, structural condition, zoning limits) rather than an average, whether their allowances are realistic, and whether change order markup appears in the contract as a number. Five specific questions separate the field in one conversation.
Most licensed contractors in San Jose can build to code. The variation between them is not craftsmanship, it is how honestly they price the unknowns and how they behave when something unexpected turns up, which on a 1965 house it will.
Start with the checks that take ten minutes
| Check | Where | What you are looking for |
|---|---|---|
| Licence status and classification | California licence board website | Active, and the right class for your work |
| Workers’ compensation | Same lookup | Current, not lapsed or exempt with employees on site |
| General liability | Certificate sent by the insurer or broker | Adequate limit for your project value |
| Complaint and disciplinary history | Same lookup | Any pattern, not a single old item |
| Bond status | Same lookup | Active |
| Business longevity | Licence issue date | A licence issued last year is a different risk profile |
Insist the insurance certificate comes from the insurer or broker directly rather than as a photocopy. Lapsed policies are the reason.
What portfolios do and do not tell you
A portfolio shows finish quality and taste, which genuinely matter. It does not show whether those projects came in near budget, finished near schedule, or generated disputes.
The more useful request: two references from projects finished 18 to 36 months ago, not last month. Recent clients are still in the glow of a finished kitchen. Clients two years out have lived with the work, found any defects, and know how warranty calls were handled.
Ask those references three questions:
- What was the final number against the contract, and why did it change?
- How long did it take against the schedule you were given?
- Did you have to chase anything after the final payment?
The third question is the one that finds out the most, because it separates contractors who finish from contractors who move on at 95 percent.
The five questions that separate the field
1 · “What does your number assume about my house?”
A price given without seeing the electrical panel, the crawlspace, or the zoning limits is an average, not a quote. On a San Jose remodel the house-specific unknowns are large:
| Condition | Cost if present | Common in |
|---|---|---|
| Electrical service at 100 or 125 amps with no capacity | $5,000 – $10,000 | Pre-1980 homes |
| Unbolted mudsill and unbraced cripple walls | $4,500 – $12,000 | Pre-1960 homes |
| Galvanized supply lines | $4,000 – $22,000 | Pre-1965 homes |
| No wall insulation, exposed during work | $2,500 – $8,000 | Pre-1978 homes |
| Duct leakage above the code threshold | $4,000 – $14,000 | Original flex duct, any era |
| Bearing wall where a non-bearing one was assumed | $12,000 – $38,000 | Ranch floor plans |
A good answer sounds like: “this number assumes the panel has capacity and the wall is non-bearing; I have not verified either yet and both would change it.” An answer of “it is all included” without having looked is not reassurance, it is an unpriced risk you will pay for later.
2 · “Can I see the allowance schedule as a separate document?”
Two bids can differ by $80,000 and be identical except for allowances. Check the numbers against reality and check whether each allowance covers material only or installed.
- Tile allowance quoted per square foot with no labour is roughly half the real cost
- Kitchen cabinetry allowance under $35,000 on a full remodel in this market is optimistic
- Lighting allowance is the one most often set unrealistically low
- Appliance allowance should reflect what you actually intend to buy, not a placeholder
A low allowance is not a lower price. It is a change order scheduled for month five.
3 · “What is the change order markup, as a number?”
If it is not in the contract as a percentage, it will be decided when the work is already necessary and you have no alternative supplier.
Ask also whether markup applies to credits. If a change reduces scope, do you get money back at the same rate? Contracts silent on this mean changes only ever go one direction.
4 · “Which agency reviews this, and what is the current plan check time?”
A contractor who works in San Jose answers immediately: the San Jose Permit Center, and a realistic current range. One who is vague either does not work here often or is not the one handling permitting, and you should know which.
Follow up with the questions that reveal local experience:
- What is the daylight plane and does it affect my project?
- Does my lot coverage allow what I am asking for?
- Will this trigger Title 24 requirements, and which ones?
Those three are San Jose-specific and someone who works here has answered them a hundred times.
5 · “Who is actually on site, and who is my point of contact?”
| Model | What to expect |
|---|---|
| Own crews for carpentry, subs for trades | Most common; good control over the core work |
| All subcontracted, contractor manages | Works well with a strong project manager, poorly without |
| Owner-operator running the site personally | Excellent attention, limited capacity if they take another job |
The question that matters more than the model: who do I call, how quickly do they respond, and are they on site daily? A project with no daily on-site supervision is where trade coordination problems come from.
How to compare bids that are not comparable
Bids for the same project routinely differ by 40 percent, and it is almost never quality. Normalise them before comparing:
- List every item in the highest bid and check whether the others include it. Design, engineering, city fees, Title 24 compliance, duct testing, painting, flooring, landscaping repair and final cleaning are the usual omissions.
- Put the allowances side by side. Adjust each bid to the same allowance values.
- Check for a contingency line. A bid with none on a 50-year-old house is not more competitive, it is less complete.
- Check who carries the permit fees. On a large project this is $14,000 to $38,000 and bids differ on it.
- Then compare. The spread usually collapses to 10 or 15 percent, which is a real difference you can evaluate.
If the low bid is still 30 percent below after normalising, something is missing from it that you have not found yet.
Red flags
- A deposit above $1,000 or 10 percent of the contract, whichever is less. That is the legal cap in California.
- A firm price at the first meeting, before seeing the panel, the crawlspace or the zoning numbers.
- A price that expires in 48 hours, or pressure to sign at the meeting.
- Reluctance to provide lien releases with each payment.
- No written change order process.
- Scope described in a paragraph rather than itemised.
- Suggesting work be done without a permit to save time or fees. It becomes your problem at resale, and it is your property.
- References only from the last few months.
What a good first meeting looks like
It should produce four things: what your zoning actually allows on your lot, whether the electrical service and structure can carry the project, a realistic range with the assumptions stated, and an honest answer about whether you can stay in the house.
It should not produce a signature. A contractor comfortable with you taking two weeks and getting two more bids is a contractor confident in their number.
The five questions, together
- What does your number assume about my house, and what have you actually verified?
- Can I see the allowance schedule separately, and does each allowance include labour?
- What is the change order markup as a number, and does it apply to credits?
- What is the current plan check time in San Jose, and does the daylight plane affect me?
- Who is on site daily and who is my point of contact?
A contractor who answers all five specifically and without hedging is telling you how your project will run. One who deflects on three is telling you the same thing.

Frequently Asked Questions
How do I choose a remodeling contractor in San Jose?
Start with the ten-minute checks: active licence with the right classification, current workers’ compensation, a liability certificate sent by the insurer directly, and complaint history. Then ask what their number assumes about your specific house, ask for the allowance schedule separately, and ask for the change order markup as a stated number. Portfolio photos and price per square foot are the least predictive things available.
Why do bids for the same project differ by 40 percent?
Almost never quality. Usually allowances and omissions. Design, engineering, city fees, Title 24 compliance, duct testing, painting, flooring and final cleaning are commonly in one bid and out of another. Normalise every bid to the same scope and the same allowance values first, and the spread typically collapses to 10 or 15 percent. If a low bid is still 30 percent under after that, something is missing you have not found.
What references should I ask for?
Two from projects finished 18 to 36 months ago rather than last month, since recent clients are still in the glow. Ask each one what the final number was against the contract and why it changed, how long it took against the schedule given, and whether they had to chase anything after final payment. That last question separates contractors who finish from contractors who leave at 95 percent.
What is the biggest red flag?
A firm price at the first meeting, before anyone has looked at the electrical panel, the crawlspace or the zoning limits. On a pre-1980 San Jose house those unknowns are worth $5,000 to $38,000 each, and a number that does not account for them is an average being presented as a quote. A deposit above $1,000 or 10 percent of the contract is a close second, because that exceeds the legal cap.
What San Jose specific questions should a contractor be able to answer?
What the current plan check time is at the San Jose Permit Center, whether the daylight plane affects your project, whether your lot coverage allows what you are asking for, and which Title 24 requirements the work will trigger. Anyone who genuinely works in San Jose has answered all four many times and will answer immediately.
