how we build
Habitat for Humanity of Tuolumne County builds to “Green” standards and is compliant with all California building codes.
We have a moral and financial responsibility to our partner families and the community to design and build homes in an environmentally and structurally responsible way. The average monthly energy consumption for our homes in Parrotts Ferry Village is $10/home from our local utility service provider PG&E. Homes are built with photovoltaic solar systems on the roof to supplement electricity. The onsite solar power source can reduce electricity bills by as much as 70 percent. In addition, all appliances are ENERGY STAR rated and homes have energy-efficient tankless hot water heaters.
Our goal is to build homes that are energy efficient today and that will remain energy efficient in the future, with ratings that are higher than what current California Title 24 standards require.
Given the high fire risk in Tuolumne County, homes are outfitted with fire-sprinkler systems, per California new construction building code.
Starting in 2017, homes built at Parrotts Ferry Village will include:
- GAF composite roofing shingles
