Home Remodeling in Rancho Cucamonga

Most of Rancho Cucamonga was built between 1980 and 2009

The Census Bureau's 2024 American Community Survey counts 60,879 homes in Rancho Cucamonga with a median year built of 1988. The 1980s were the biggest decade, with 16,157 homes, and 63 percent of the housing went up between 1980 and 2009. Fewer than 1 in 10 homes predate 1970. That makes the typical project here a first full update: the original roof, windows and air conditioner, and a kitchen or bathroom that still has its builder finishes.

The 2003 Grand Prix Fire burned through the city's entire wildland edge

The city's Community Wildfire Protection Plan describes Santa Ana winds with gusts that can exceed 80 miles per hour, and CAL FIRE research it cites found embers can travel more than a mile into neighborhoods. In October 2003 the Grand Prix Fire was driven west by those winds, burned through the whole wildland interface of Rancho Cucamonga and more than 50,000 acres in total, and destroyed 15 homes in the city. The city and its Fire District mapped a Wildland Urban Interface Fire Area covering nearly a third of the Fire District's service area, including the foothill neighborhoods of Alta Loma and Etiwanda. Homes there fall under the state's Chapter 7A wildfire building rules, which require Class A roofing and ignition resistant vents, siding, decks and windows.

Rancho Cucamonga designs homes for 110 mph wind

The city amends the California Residential Code so that homes are designed for an ultimate wind speed of 110 miles per hour with Exposure C, the category for open terrain. That rule, carried forward in Ordinance No. 1048 in November 2025, affects how a patio cover, pergola, addition or new roof has to be anchored and fastened. The city also requires at least a Class A or B fire rated roof covering on new homes, additions and reroofs outside the very high fire zone, and Class A inside it, and requires a soils report when an addition is more than half the existing floor area, with reports older than 3 years updated.
