# Renovation prices in Santa Barbara County: 2026 ranges

Santa Barbara, Goleta, Carpinteria, and Montecito on the South Coast, plus Santa Maria, Lompoc, and the Santa Ynez Valley up north. The South Coast is the priciest market we cover.

What moves prices here: a small South Coast trade pool, coastal and historic design review, and high finish expectations.

## Where prices run highest and lowest

In our October 2026 cost tables, [Montecito](https://keystoneconnect.us/cities/montecito) is the most expensive place in Santa Barbara County to renovate, about 39% above the county average, and [Guadalupe](https://keystoneconnect.us/cities/guadalupe) the least expensive, about 26% below it. A mid-size kitchen remodel runs $56k–$104k in Montecito and $30k–$56k in Guadalupe. 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.
