Downtown Fullerton and the streets around it include some of the city's oldest buildings, from early twentieth century houses to commercial and mixed-use blocks. Many have been renovated more than once, so plumbing can be a patchwork of eras.
Water heaters here may sit in tight utility closets, back porches, basements or shared mechanical spaces. Apartments and mixed-use buildings may have shared systems managed by an owner or property manager.
Building types and what to expect
| Building | Water heater notes |
|---|---|
| Older single-family homes | Often raised floors; heater in a porch, closet or garage; mixed pipe materials |
| Small apartment buildings | Individual or shared heaters; tenants should contact the owner or manager |
| Mixed-use buildings | Commercial and residential systems may differ; owner coordinates work |
| Renovated historic homes | Ask about permit history and what was replaced |
