New roof installation in La Puente covers the roof on an addition, an ADU or a new building, permitted through the city's Building and Safety Division. La Puente is in climate zone 9, and ACS 2020-2024 gives 1958 as the median year built.
The permit office for new roofs
The City of La Puente's Building and Safety Division provides plan checking, permit issuance and inspection. A new roof on new work is reviewed with the rest of the structure, so its details belong in the plan set from the start.
Ask the division what it expects for your project, and bring the roof details with the rest of the drawings.
Where new meets old
Because the median La Puente home dates to 1958, an addition or ADU often shares a wall or a roofline with an older structure. The new roof can follow the old one in slope and color. The layers underneath belong to the new frame, and the junction gets its own flashing.
About 3,900 owner-occupied single-family homes are counted here (ACS 2020-2024).
Energy code and fire class
The 2025 Energy Code, in force since 1 Jan 2026, carries the roof text of the 2022 code forward (California Energy Commission). Fire rules for hazard areas are in Title 24 Part 7 (DGS/California Building Standards Commission, 2025).
A required fire class follows the mapped zone, which is set by address. Check the address on the CAL FIRE map viewer.
