ADU Quotes in Agoura Hills
How an Agoura Hills ADU quote is laid out phase by phase, why the unit type moves it most, and how finish selections and fire mapping change the lines.
A written quote for an Agoura Hills ADU follows the order the building goes up: permit drawings, site work, foundation, shell, systems, interior finishes and closeout. Each phase is its own line with a short scope note beneath it. We write it after a visit to the lot, and when the parcel can take several unit types, each type gets a separate column so the totals can be read across.
Choices that change a column
The largest movement comes from the type itself. A detached unit carries a foundation, roof and utility trench of its own. A garage conversion reuses walls and a slab, though both must pass inspection as living space. An attached unit shares a wall and can draw on systems already in the house. A JADU stays within existing rooms. Inside any type, finish selections move the interior lines: cabinet grade, flooring, plumbing fixtures and the kind of heating and cooling. Each selection is listed with a default named beside it, so a change shows exactly which line it lands on.
Fire mapping and review comments
Parts of Agoura Hills appear on fire hazard maps, and a lot inside a mapped area may be held to ember-resistance rules. Those rules reach the shell lines, from the Class A roof and the vent screens to the soffits and the cladding near grade. The City of Agoura Hills reviews the drawings, and a comment from its plan checker can add a detail, a calculation or a note to the set. That addition is priced on the line it touches. Where the lot is not flat, soil testing may enter the drawings phase so the footings are sized from real data.
