A new roof starts on paper. In Rosemead the plan names the covering, the slope and the fire class, then goes to the city. Census Bureau figures for Rosemead: median year built 1959, 4,925 owner-occupied single-family homes, median home value 807,200 dollars (U.S. Census Bureau, ACS 2020-2024).
The city office
Rosemead has a Building and Safety Division in Community Development (City of Rosemead). It issues permits for new construction and takes the plan sheets, so it is the office to ask about a new roof.
We can help you build a scope that matches the plans, which keeps the counter visit short.
Fire hazard notes
The city says a small area is identified as fire hazard, with no level given (City of Rosemead). Check the address on the CAL FIRE map viewer.
If the address is mapped, check with the city's building department for the class the plans must carry.
ADUs, additions and Title 24
An ADU or addition roof can be drawn to match the house or to stand apart. Matching is a design choice.
Title 24 energy rules are now the 2025 Energy Code, in effect from 1 January 2026 (California Energy Commission, 2025). Rosemead is in climate zone 9 (California Energy Commission, 2022), and the designer sets the values.
