## Where prices run highest and lowest

In our October 2026 cost tables, [Thousand Oaks](https://keystoneconnect.us/cities/thousand-oaks) is the most expensive place in Ventura County to renovate, about 7% above the county average, and [Santa Paula](https://keystoneconnect.us/cities/santa-paula) the least expensive, about 14% below it. A mid-size kitchen remodel runs $39k–$73k in Thousand Oaks and $32k–$59k in Santa Paula. The difference is mostly labor rates, permit fees and site conditions.

## How to read these numbers

### How are these county cost ranges calculated?

+

Each project type starts from a 2026 Los Angeles County baseline, adjusted by a county multiplier for local labor, permitting and site conditions. City pages apply their own multiplier. Planning estimates, not quotes.

### How do I get a real price for my project?

+

Get two or three bids on the same scope from licensed builders. Keystone Connect lines them up and lays the bids side by side, free to homeowners.

## Want real bids for your Ventura County project?
