Why Plano pays $60 more than Frisco on auto, despite being a mile apart

Two friends, two renewal letters, same week in April. One lives in a 2014 build on the West Plano side of Spring Creek Parkway. The other moved to a 2019 build in east Frisco about a mile north. Same compact SUV on both driveways, same age range, same clean record on both, same coverage limits and same deductibles. Plano letter: about $1,877 a year. Frisco letter: about $1,530. Same Collin County. Same school feeder pattern, mostly. Same severe-weather corridor overhead. So why does Plano cost $347 more on this comparison, and roughly $60 more on the closer publisher-to-publisher cut?

Most of it isn't the customer. It's the housing stock, the loss history, and the way carriers draw their territory factors inside one fast-growing county.

The numbers, with the publisher footnote

Plano's average full-coverage auto premium runs about $1,877 a year per Compare.com's 2024 Plano city page. Frisco, on the same Compare.com / MoneyGeek 2024 methodology, lands in the $1,411 to $1,528 range, with $1,530 a fair midpoint that's still slightly under the publisher's Texas baseline. Both cities use the Compare.com $1,818 Texas baseline, not the Bankrate $2,751 number. The two publishers use different driver profiles, vehicle mixes, and coverage assumptions, so their state averages don't line up. We're holding the methodology constant inside the same publisher to compare these two cities fairly.

Against the Compare.com $1,818 baseline, Plano sits about 3% above and Frisco sits about 16% below. That's the gap that produces the $60-and-up monthly difference some Plano households see when they actually shop a Frisco address.

Both cities sat under the same statewide 2024 rate-filing cycle. Per S&P Global Market Intelligence's 2024 rate-filing tracking summarized in trade press, approved rate filings on the Texas homeowners market ran in the high-teens (around 19%) on a premium-weighted basis, while personal-auto filings ran lower, in the mid-single-digit range. The aggregates are blended market averages, not any single carrier's number. Some filed higher, some lower, some flat. The filing cycle hit both Plano and Frisco at the same time. The structural gap between the two cities sat on top of it.

Why Frisco runs cheaper

Four inputs separate the two ZIP grids, none of them dramatic on their own.

Newer housing stock is the first. Frisco's median build year is meaningfully later than Plano's. Frisco was a 33,000-person town in 2000 and crossed 225,000 by the Census Bureau's Vintage 2024 estimate. Plano's growth happened a generation earlier. That timing shows up in the housing footprint: Frisco neighborhoods skew toward larger lots, attached garages on every house, more new-build cul-de-sacs, and fewer apartment blocks per square mile. Cars parked in attached garages get stolen less and damaged less in hailstorms. Comp claim frequency follows. Comp rate follows that.

Theft is the second. NICB regional data has Collin County running well below the urban Texas average on auto theft, but the city-level read inside the county still varies. Frisco's theft frequency tracks slightly below Plano's on multi-year DPS reporting. It's not a dramatic difference, but underwriters see it and the territory factor reflects it.

Density is the third. Plano's developed footprint is older and tighter near the Legacy West and downtown grid. More cars closer together on the same blocks means more collision frequency per insured vehicle in those ZIPs. Frisco's growth spread out instead of up: bigger setbacks, wider streets in the newer master-planned sections, more open distance between vehicles. Collision frequency drops a few percentage points on the territory factor and the premium follows.

Commute pattern is the fourth, and it's the one nobody talks about. Plano sits closer to the Dallas employment core on the Dallas North Tollway and on US-75. Plano commuters spend more daily miles on the highway segments that produce the most claims in the metroplex. Frisco's job base has grown north into the city itself, around The Star, the PGA campus, and the Frisco Station / Hall Park developments. More Frisco residents work in Frisco than Plano residents work in Plano on a percentage basis. Fewer commute miles, fewer collision exposures, lower territory factor.

Stack those four together and you have most of the gap. Each one shaves a little off the territory factor a carrier assigns the address, and the territory factor is the lever that moves the bill.

What's the same on both sides of the line

Hail. Collin County's hail exposure doesn't care about the Plano-Frisco boundary.

The DFW corridor's June 2023 supercell ran an estimated $7 to $10 billion in insured losses across the metro, with hail responsible for about 95% of that damage per the Insurance Information Institute and CoreLogic figures compiled in the InsuranceQuotes post-event writeup. The March 2024 hail event added an estimated $3.2 billion in vehicle damage across North Texas. Both storms crossed Collin County. Both produced roof claims on both sides of the Plano-Frisco line. Wind and hail together account for roughly 60% of homeowner losses across the DFW counties in a normal year on TDI's published data.

That's why the home-premium picture between Plano and Frisco is closer to flat than the auto picture. City-specific homeowner-premium averages aren't separately published for either Plano or Frisco. Both track the broader DFW-corridor average that Steven J Thomas pegged around $3,500 on a $300K dwelling for 2024. Hail is a corridor exposure, not a city-line exposure. Carriers price it across the whole footprint and the 2024 filings landed about the same way on both sides of the boundary.

The ZIP-code reality inside each city

The city average smooths over real spread inside each one.

Plano's 75025 / 75093 west-side ZIPs typically quote lower than the 75074 / 75075 older-east-side ZIPs on the same clean-record full-coverage profile. The spread between Plano ZIPs commonly runs $150 to $300 a year on a basic comparison. Frisco's 75033 / 75034 west-side ZIPs and the 75035 / 75036 ZIPs each carry their own territory factor too, with the older 75034 segment around Lebanon Road sometimes pricing closer to north Plano than to the rest of Frisco.

Two addresses three miles apart, on opposite sides of the Plano-Frisco line, can quote five to ten percent differently on the same coverage profile. Two addresses three miles apart inside the same city often quote close to that, too. The city line on a map isn't a hard line on the premium. The ZIP boundary inside the carrier's territory file is.

Texas Insurance Code §551.105 (Use of Claims Information) restricts a carrier's use of weather-related claims information against an individual homeowners policyholder for surcharge or non-renewal. It doesn't block ZIP-level base-rate resets. Carriers can and do reset territory factors after a loss cycle, which is how a clean-record household ends up with a higher renewal even though they personally never filed. Their ZIP did, in aggregate.

What it means at renewal

Considering a move from one side to the other? Pull a side-by-side quote before you sign the lease or close on the house. Have your agent run identical coverage on both addresses on the same day. On auto, the Frisco number usually comes in lower for an otherwise-identical profile, but not always. A 75034 quote against a 75093 quote can flip the expected order on some carriers' books. Get the actual numbers.

Staying put? The renewal playbook reads the same on either side. Get at least two quotes in front of you at once. One from a captive agent who writes a single carrier you already work with, and one from an independent who can run your address across five or ten companies on the same coverage. Make both quote the same limits and deductibles so you're actually comparing the same product. Ask about telematics if you're a low-mileage household. Ask about multi-policy bundling if you own the home and the cars at the same address. Ask whether the agent re-quoted you against multiple carriers inside the past 90 days or just renewed you on the same one.

Five questions to bring to your local agent

A short list either side of the line.

1. What's the territory factor on this exact address, and how does it compare to the city average? Carriers won't always print the factor on the declarations page, but a good agent can tell you whether your ZIP is pricing above or below the city baseline.

2. When did the carrier last reset their Collin County territory file, and what did it do to renewals at this ZIP? Post-hail-cycle resets land at different times for different carriers.

3. Are there discounts on the table that the current policy doesn't carry? Multi-vehicle, multi-policy, telematics, defensive driving, paid-in-full, and electronic-funds-transfer discounts each shave a small percentage. Several of them together can close $200 a year.

4. If I moved one ZIP over inside the same county, what would the same coverage cost? Useful before a move and useful as a sanity check on whether you're being quoted fairly today.

5. Did you re-shop me against more than one carrier this renewal, or did you renew me on the same one? Collin County auto appetite shifts inside the Texas filing cycle, and the carrier that wrote your best rate two years ago may not be the cheapest for your address today.

If you want to compare quotes locally, both directory pages are the starting point. The Plano directory page lists several hundred licensed agencies serving the Plano side, and the Frisco directory page covers the Frisco side. Pick at least one captive and at least one independent on whichever side you're shopping. Plano-to-Frisco premium differences vary more between carriers than the city-average gap suggests, so the spread on a re-quote is usually wider than households expect.
