# Renovation prices in San Diego County: 2026 ranges

From Oceanside and Carlsbad down to Chula Vista, and east to El Cajon and Ramona. Coastal cities price at a premium; East County and South Bay run closer to Inland Empire rates.

What moves prices here: coastal-zone review, hillside lots in North County, and a tight trade-labor market.

## Where prices run highest and lowest

In our October 2026 cost tables, [Del Mar](https://keystoneconnect.us/cities/del-mar) is the most expensive place in San Diego County to renovate, about 47% above the county average, and [Campo](https://keystoneconnect.us/cities/campo) the least expensive, about 16% below it. A mid-size kitchen remodel runs $53k–$98k in Del Mar and $30k–$56k in Campo. 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.
