A Mid-Peninsula Homebuyer's Guide to Property Tax and Permit Lookup for Homes in San Carlos, Belmont, and Redwood City

How do you do a property tax and permit lookup for homes in San Mateo County? You might "kick the tires" or check "under the hood" when buying a car, but when it comes to buying Mid-Peninsula real estate, you'll have to do some digging. (Metaphorically, of course. Bringing a shovel to the open house is not recommended.)

If you're a homebuyer in San Carlos, Belmont, or Redwood City, the good news is that you can research property tax and permit info from the comfort of your own home, without getting your hands dirty. Here are the tools you'll need and where to find them.

Where Do You Start a Property Tax and Permit Lookup in San Mateo County?

San Mateo County makes it simple to research property tax records, and that's the natural first stop on any property tax and permit lookup. The Property Tax Look-up tool on the County Assessor's website is where you'll begin.

Using the property address (or parcel number, if you happen to have it) you can pull up a wealth of useful information on a home you're considering. Here's what you can find:

Property tax status. Current status of taxes, showing paid or unpaid.
Annual tax amounts. Both the first and second installment amounts for the year.
Ownership history. A record of who has owned the property over time.

This information helps you understand the true cost of ownership and gives you a window into the property's history before you ever set foot in an open house. For a deeper look at how San Mateo County property taxes work, including assessment rules, deadlines, and exemptions, the Assessor's office provides a thorough overview of secured property taxes.

While you're researching, our Mid-Peninsula home search portal is a good page to bookmark alongside the tax lookup tool so you can run both searches side by side.

How Do You Look Up Home Permit History in San Carlos, Belmont, and Redwood City?

Permit history lookup happens at the city level rather than the county level, so the portal you use depends on where the home is located. Each of our main service areas runs its own building department and online lookup tool:

San Carlos: permit lookup portal and the San Carlos Building Department website for more information. To get to know the area, visit our San Carlos community page.
Belmont: permit lookup portal and the Belmont Permit Center. Learn more about the area on our Belmont community page.
Redwood City: permit lookup portal and the Redwood City Building Inspection and Code Enforcement page. Read up on the area on our Redwood City community page.

Why bother with a permit history search in the first place? Permit records reveal the story of any permitted work done on a home. That includes when the roof was replaced, when A/C was added, when a kitchen or bathroom was remodeled, and when major additions or structural changes were completed. Taken together, those records give you a clearer picture of how the home has been maintained and what kind of investment has gone into it over the years.

There's an important flip side, too. Permit history will not show unpermitted work, and that absence can be just as telling. If you walk through a home and notice an obvious new addition, a converted garage, or a finished basement that doesn't appear in the permit records, that's worth flagging. Unpermitted work can affect resale value, insurance coverage, and sometimes the safety of the home itself. Knowing what isn't on file is part of being an informed buyer.

What Are the Limits of Online Property Tax and Permit Lookup?

Online property tax and permit lookup tools are a great starting point, but they don't tell the full story of a home. Tax records won't reveal the condition of the roof, and permit history won't tell you whether the foundation is settling or how the plumbing was actually installed. That's where professional inspections come in.

In the Mid-Peninsula market, sellers often complete inspections ahead of time and include the reports in the disclosure package shared with prospective buyers. Offers in San Carlos, Belmont, and Redwood City rarely include inspection contingencies, so most of the inspection work tends to happen upfront. Even so, buyers may still bring in a general inspector at some point in the process for an independent look. Reviewing pre-inspection reports carefully, and knowing what questions to ask about them, is one of the most important parts of buying a home in our market. If you have questions, we are happy to guide you through them.

This is also where working with an experienced local team makes a real difference. The top San Carlos real estate agents at Veritas Homes have spent two decades helping buyers interpret disclosures, vet inspection findings, and understand what permit and tax records actually mean for a specific property. Our team knows the patterns of these neighborhoods, the contractors who do reliable work, and the questions that protect buyers from costly surprises after closing.
