West Hollywood

Room Additions contractor in West Hollywood

Adding a bathroom to an addition is what separates a straightforward room from a coordinated one. Supply is the easy half. Waste is the half that decides the plan, because a drain has to fall toward the existing main at a consistent slope, and the route it takes sets the floor structure above it. Vent lines have to reach the roof. Fixture positions get fixed before the slab is poured or the joists are cut, since moving a toilet after concrete is a demolition job. Hot water is checked as well, since another bathroom draws on equipment already serving the house. All of that is drawn and specified ahead of framing, then run and inspected before anything closes.

No price appears on this site for any service, and that is a position rather than an oversight. A number comes out of a scope, and a scope comes out of a visit to the house. The visit is free. So is the written estimate, which is a detailed scope of work with a remodeling consultation handed over together. Permit filings and inspection bookings are the builder's responsibility. Financing exists. The finished addition is covered by a warranty of 5 years. The contractor is licensed and insured, working under CSLB #1072368, and holds Yelp top contractor reviews 2023-2025.

West Hollywood area

Room additions are judged on the join rather than on the new square footage. Roofline, foundation depth, wall thickness and window rhythm all have to match what is already standing, or the addition reads as a bolt-on forever. Norma Triangle is a neighborhood name on this city's map.

I recently hired My Cali Builders for a backyard remodel and couldn't be happier. Danny and his team were professional, punctual, and easy to communicate with. They really paid attention to the details and brought my vision to life. The quality of the work exceeded my expectations from start to finish. Everything was done cleanly and on schedule, which I really appreciated. Danny made the whole process smooth and stress-free. The backyard now looks amazing and feels like a completely new space. I would definitely recommend them to anyone looking for reliable contractors.

I began my Yelp search for a company to perform structural repairs and ultimately chose 5 companies, scheduling each of them for a representative to visit and discuss my needs. I chose My Cali Builders based upon Danny's (owner) review of the work and how he defined the scope of the work. The other representatives vacillated on the scope of the work and attached various caveats. My Cali Builders also gave me the best bid. So I hired them and boy, am I glad I did. Work was performed quickly, efficiently and the finish work was excellent. Every task I initially discussed with Danny was completed. Danny's crew including Francisco and Jaime, were top notch and pleasant. Each day, refuse and trash were removed. Every day, Danny either visited or texted to advise on progress and to insure the work was progressing as discussed and to ask if I was satisfied and happy. I can't convey in words how much I appreciated My Cali Builders. Look no further, they are the best I've ever encountered.

Danny Raz is a man of action; the work was done promptly and even finished ahead of schedule. The workers were polite, respectful, of cleaned up well after the job.

There is no published price for an addition on this site. What moves the number most is not floor area but what goes inside: a plain room, a room with a bathroom, and a room with a kitchenette are three different scopes at the same square footage. Structure, services and finish level fill in the rest, and the free onsite visit is where all of it is written down.
Yes. Licensed and insured, under CSLB #1072368, which can be checked with the state board in a minute. That check is worth running on every bidder rather than only on this company. Work that reaches the frame of the house makes the licence something to verify rather than assume. In business since 2020, with Yelp top contractor reviews 2023-2025.
Finished work is covered by a warranty of 5 years, and that single term is the whole of it. It appears in the scope of work rather than in a separate leaflet, alongside the licence, CSLB #1072368. Bring any question about how it applies to a particular addition to the remodeling consultation, where the specification it attaches to is being discussed anyway.
