Tarzana

Room Additions contractor in Tarzana

An addition is designed against a house that was built to a drawing nobody has any more. So the first real work is measuring what is actually there: wall lengths, ceiling heights, floor levels between rooms, where the panel sits, which walls carry load and which do not. Ceilings and walls get opened where the connection will be made, because a joist direction assumed from outside is a guess. Those measurements become the base plan the new rooms are drawn onto, and they decide where a beam can land and how wide an opening can be. Skipping this stage produces a set of drawings that stops working the day framing starts.

Bring questions and the visit does more work. What the room is for, whether a bathroom goes in it, what the ceiling should do, whether the existing flooring can be extended: all of that shapes the document that comes out. Nothing is charged for the walkthrough of the rooms the addition will tie into, and nothing is charged for the written estimate that follows it. It is a detailed scope of work, with a remodeling consultation attached. Permit filings and inspection bookings are handled. Financing exists. A 5 year warranty covers the finished addition. The licence is CSLB #1072368, and the builder is licensed and insured. Call or text (310) 220-0903.

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.

Yes. Permit submissions and inspection scheduling are carried by the company as part of the work, and they follow the scope of work written after the free onsite visit. Accurate measurements of the existing house feed straight into that paperwork, so the visit is a survey rather than a look around. Call or text (310) 220-0903 to arrange one.
No price is published for an addition anywhere on this site. What sets the number is the scope: the size of the new structure, what the foundation has to do, how much of the existing house is opened up, and the finish specification. Surprises behind old walls move it too, and that is one reason the free onsite visit measures rather than eyeballs from the kerb.
