Math index

Search for the thing you are stuck on. Each link opens that scene.

Guide contents

Sections 1 and 2 first. Then follow your stage.

Tool families

The number is how many tools sit in the family. Each link opens the first tool in it.

Built for this coast

Montecito is County land. Check your address.

Montecito is unincorporated County of Santa Barbara, so City of Santa Barbara window rules do not apply there [B]. County permit rules for windows and doors, the County's building code edition and adoption date, coastal and hillside rules and any construction-hours rule were not found. County BAR review applies in the Montecito Community Plan area, and the County's quiet hours for amplified sound are 10 p.m. to 7 a.m. Sunday to Thursday nights and midnight to 7 a.m. on Friday and Saturday nights (construction not mentioned). Call the County counter. Montecito Fire adopted the 2025 California Fire Code and WUI Code on Nov 17, 2025 [S7]. The guide's local rules table lists each item as confirmed or unconfirmed.

Sill-pan slope

Crew practice, not a sourced number. The window maker controls. [P][V]

Energy values conflict

Roseville and Elk Grove 2025 forms show U 0.27 and SHGC 0.23, San Bernardino County quotes 0.30. None is Santa Barbara. Use the NFRC label and the CF1R. [V]

Tape widths

4, 6 and 9 in are common sizes, not code rules. Follow the WRB and unit makers. [S8][S11]

Plans win

The approved plans, the adopted California codes, the unit maker's instructions and your inspector overrule this site.

Safety first

Read guide section 1 before you use a tool. Set ladders at one quarter of the working length.
