Tenant Improvements in North Hollywood

Adding offices to a North Hollywood suite? Sprinkler layout, shared-wall details and LADBS review are planned before the build-out gets its written price.

Will the sprinkler heads have to move if we add 2 private offices? Usually some will. A new full-height wall in a North Hollywood suite can block a head's discharge or leave a fresh room with no coverage, so the sprinkler layout follows the floor plan. During that first walk we note head positions, ceiling height and where the branch lines run, and the quote then carries the sprinkler work from the start.

Sprinklers, ceilings and new rooms

A licensed fire sprinkler contractor redraws the affected branch lines and submits them for fire review apart from the architectural plans, so that submittal runs alongside plan check. Heads are added or moved to keep each new room covered, and the ceiling grid is laid out around them. If a soffit or bulkhead drops below existing heads, they may need to come down to it. We price the sprinkler drawings, the fitting work and the drain-down of the system as separate lines, since the building's rules decide when the system can be shut off.

Walls that touch the neighbors

A wall shared with the next suite may be a rated assembly, depending on the building's construction type and occupancy, and the drawings or a look above the ceiling tell us which. If it is rated, any new outlet, duct or cable passing through it needs a listed firestop system. If it is not, sound insulation and sealed gaps still keep calls and printers from carrying through. Either way, the layout keeps new doors, power and data on interior walls where it can, and the quote marks any work that touches the shared wall.
