Straight answers about building in California

The questions homeowners actually ask us — answered properly, including the ones where the honest answer costs us money.

Home  /  Guides

Most contractor websites answer one question: what does it cost. That is usually the last thing a homeowner needs to know and the first thing everybody publishes.

These pages answer the questions that come earlier and matter more — whether a deposit request is legal, why two bids on the same yard came back $80,000 apart, what a change order is supposed to look like before you sign it. Some of the answers work against us commercially. We publish them anyway, because a homeowner who understands how the work is priced is a better client than one who doesn't, and because it is the truth.

Every number here comes from our own projects or from California law, and where we don't know something — a specific city's permit fee, a size limit that varies by jurisdiction — we say so rather than guessing. Written by a licensed general contractor building in Santa Clara and San Mateo counties.

Hiring a Contractor

Your contractor asked for 50% up front. Is that legal?

Short answer: no. And of every warning sign on a residential job, this is the one that costs homeowners the most money.

ADUs

Why two ADU quotes can be $80,000 apart

Two builders walk the same yard and come back $80,000 apart. Usually neither one is lying. They are quoting different scopes, and the difference is mostly in the work that happens before anyone breaks ground.

ADUs · California Law

Your city has to offer pre-approved ADU plans now

A state law that took effect in January 2025 changed the ADU permitting math, and most homeowners — and a fair number of builders — still don't know it exists.

During Construction

When should you refuse a change order?

Change orders are normal. Change orders you find out about after the work is done are not, and the difference is entirely about when the paperwork happens.

Buying & Selling

The inspection found unpermitted work. Now what?

You have a closing date and a problem that was built ten years ago. Here is how this normally plays out, and the three decisions that actually matter.

ADUs

Can I actually build an ADU on my lot?

California law made this question much easier to answer. What it did not do is make every lot the same.

ADUs

Converting your garage into an ADU

It looks like the easy one because the structure already exists. Usually it is. Here is where it stops being easy.

Hiring a Contractor

Your contractor stopped showing up. Here is what to do.

Half-finished, money already paid, and the phone stopped being answered. The order you do things in from here matters more than you would expect.

Permits & Inspections

What a failed inspection actually costs you

Most homeowners assume the cost is the fee. The fee is almost never the expensive part.

Structure

There is a crack in my foundation. Is it serious?

The honest version of this article is shorter than most: some cracks are normal, some are not, and the difference is not something to diagnose from a photo.

Before You Sign

Will your remodel trigger a panel upgrade?

This is the line item that most often turns a fixed price into a change order. It is also the easiest one to catch early, and the check takes an afternoon.

Before You Sign

Do you need an architect, a designer, or a builder?

The answer depends almost entirely on one thing: whether your project changes the structure, or only what is inside it.

Hiring a Contractor

How to check a contractor's license before you sign

It takes two minutes and it is the single highest-value thing you can do before handing anyone money.

During Construction

Your builder found something unexpected. What should happen next?

Almost every renovation runs into something nobody could see. The discovery isn't the problem — what happens in the next 48 hours is.

How roofing gets handled on your project

Short version: it gets done, by someone licensed for it, sequenced so it lands before interior finish.
