A Practical Guide to a Second-Story Addition in Arcadia
Review the existing structure, stair layout and construction sequence before adding a second story.
Kitchen, bathroom and whole-home remodeling explained for San Gabriel Valley homeowners.
TOPIC GUIDE
A large share of the housing stock in Arcadia and the surrounding San Gabriel Valley was built between the 1940s and the 1960s, which shapes every remodel in this area. The rooms are smaller than current expectations, the plumbing and wiring are often original, floors are rarely level, and the wall between the kitchen and everything else is usually the one everybody wants removed. None of that is a problem — it is simply what decides whether a project is a refresh or a rebuild.
The guides here deal with money and judgement rather than finishes. What a kitchen remodel costs by scope, and why moving the sink moves the number more than any finish choice. How to read a quote, and why a written scope is worth more than a single figure. What to check before signing with any contractor, including us. The pattern across all of them is the same: the cost of a remodel is set by decisions made before demolition, not by the tiles.
Budgeting? Start with what a kitchen remodel costs and what an ADU costs for comparison. Choosing a contractor? Use the eight checks — including on us. Service detail is on kitchen remodeling and bathroom remodeling. Doing several rooms at once is a different problem from doing one — see whole-home remodeling.
FAQ
It depends on scope more than size: a refresh that keeps the layout, a mid-range rebuild, a layout change, or structural work. See the cost bands and where the money goes.
Generally not for replacing finishes and appliances in place. Yes when plumbing moves, circuits are altered, or a wall is removed or relocated. Confirm your project with the City of Arcadia.
Compare written scope, not totals. Two numbers that look far apart are often two different scopes. See what to check before signing.
