Tenant Improvements in Altadena
Altadena tenant build-outs including cooking exhaust, with vent outlets planned for ember-resistance rules and county plan check. Aspenwell Construction.
Where can the exhaust from a cooking hood leave the building? In an Altadena suite that will serve food, that is a first-visit question, and the answer starts at a roof or an exterior wall the landlord controls. A lot in Altadena may lie inside a mapped fire hazard zone, and then a vent that opens outdoors can face ember-resistance rules, such as fine metal mesh over the opening.
Where the duct can go
A grease duct rises in a straight, welded run from the hood to the roof, with clearances to anything that can burn and an access panel for cleaning. Cutting the roof for it means framing around the opening so the weight of the duct and a fan reaches the structure directly and the roof sheathing carries none of it. We locate the route over the cooking line, check the framing above the ceiling, and bring in the engineer when a joist has to be cut. The duct's insulation wrap, the fan's curb and the flashing are shown on a detail so the roofer and the inspector work from the same drawing.
Fire hazard mapping and the plan set
Because Altadena has no city government of its own, the county building department is the reviewer here. The drawings show the hood, the duct, the fire suppression system and the outlet details, along with a note on how openings resist embers where the mapping applies. The landlord approves the roof penetration and its flashing, and a leak-tight curb is built around it. Make-up air is planned with the hood, so the kitchen does not pull air in through the entry door and the exhaust fan works against less resistance. The fire suppression contractor tests the system before the inspector arrives.

Tenant Improvements in Altadena: questions
Capacity depends on the slab's thickness, steel and the ground under it. A range line, a cold room and a dish station each load the floor differently, so we scan, ask for each unit's weight and let the engineer decide where a thickened pad or plate is needed.
We pass the drawings and the work letter requirements to the owner or property manager, and ask in writing about roof access, shutoffs and any restrictions on grease ducts. Work hours are fixed with them. The tenant is copied, and lease questions go to the tenant.
Moved walls, new power, plumbing, a hood and its duct, and suppression work all need one. Altadena is unincorporated, so the county building department handles it. Should the lot lie within a mapped hazard area for fire, rules for exterior openings can be added. We confirm the scope first.
