Pricing a Monrovia addition waits for good drawings, so we measure the house and have an engineer size the new beams and footings first. From there the quote lists each stage of the build on its own line. The things that move the total most are the size of the room, whether it grows out or up, and how much help the existing frame needs to carry it.

Reading the lines of the quote

Site preparation and footings come first on the page, followed by framing, the roof, doors and windows, plumbing and electrical rough-in, insulation, drywall and finish work. Plan check and permit fees sit on a line apart from labor and materials. Choices the family has not made yet, like flooring or fixtures, are carried as allowances that state what they assume. A second story brings its own entries for a stair and any reinforcement below. When a later choice or a hidden condition changes the work, we write up the change and its cost before that part goes ahead.

Fire mapping and the price

Fire hazard maps reach into parts of Monrovia. A new room on a mapped parcel must follow ember-resistance rules. We look up the address before pricing, so those requirements are part of the first quote the family reads. On a mapped lot the cladding moves to a noncombustible product, the vents carry ember screening, the eaves are enclosed and the roof covering carries a fire rating, and each of those choices shows on its own line. If the parcel is clear of the map, those same lines price ordinary materials, and the quote says so plainly.
