What a new home build covers
We build custom homes from the ground up. Our architects and engineers draw the plans and the structural calculations, GM Ironwood can pull the city permits, and the same team handles the excavation, foundation, framing and everything that goes inside the house, through the final walkthrough with you.
The photos on this page are GM Ironwood work: a farmhouse-style house with a stone base, during construction and finished, a modern house with a long wood deck, and wall and roof framing going up.

Hand-off
We walk through the finished work with you before calling it done.
For a new home, the plans and structural calculations come first, then the city permits. The city inspects the work at each stage, from the foundation and the framing to the final inspection, before the walkthrough with you.
Timeline and cost
Every house is different, so the price comes after we see your lot and the plans. Here is what changes the number:
- Size of the house and number of floors
- The lot: slope, soil and excavation
- Finishes: floors, cabinets, fixtures and windows
- Permits: how long your city takes to review the plans
You get the price and the schedule in one written bid, line by line.
Questions
Do you work outside Oakland?
Yes. GM Ironwood is based in Oakland, at 1824 79th Ave, and works across the San Francisco Bay Area, Contra Costa County and the Tri-Valley, plus the North Bay and the South Bay. The full list of cities is on our service areas page. Not sure about your city? Call (510) 479-2809 and ask.
Do you give a written estimate?
Yes. After the site visit you get a written bid, itemized line by line, before any work starts. Each line is one part of the job with its own price, so you can see where every dollar goes and decide what to include. One client wrote that the bid was detailed and itemized.
Are you licensed and insured?
Yes. GM Ironwood Construction Inc. holds California contractor license CSLB #1125088 as a Class B general building contractor. The company is bonded and carries general liability insurance. You can check the license at any time on the Contractors State License Board website, cslb.ca.gov, using that number.
Do you pull the city permits?
Yes, if you want us to. We can prepare and submit the permit package and schedule inspections, or you can handle permits yourself. Either way, the city inspects the work at each stage, and each inspection has to pass before the job moves on to the next step.
Do I need my own architect or engineer?
No. You can use our architect and structural engineer, or bring your own plans. Plans and permits can be part of our contract or separate. If you use our team, the same plans the city approves are the ones our crew builds from, so the design and the work match.
Does every city have different rules?
Yes. Each Bay Area city has its own building department, its own forms and its own local requirements, and some areas outside city limits are handled by the county. Before we write your bid, we check the rules that apply to your address, so the price already reflects what your city will ask for.
How long do permits take?
It depends on the size of the project and the city. We give you an estimate for your address with the bid. Plan review can take more than one round when the city sends comments on the plans, and larger projects usually need more review time.
Do you take commercial work?
Yes. GM Ironwood builds residential and commercial projects, including commercial renovations. The process is the same: a site visit, a written bid itemized line by line, city permits pulled by GM Ironwood, and plans with our architects and engineers when the work needs them. Call (510) 479-2809 to talk about your project.
Do you build the whole house?
Yes. GM Ironwood builds custom new homes from start to finish. Our architects and engineers prepare the plans and structural calculations, GM Ironwood can pull the city permits, and the same team runs the construction, from the foundation and framing to the finishes and the final walkthrough with you.
How are the price and schedule of a new home set?
It depends on the size of the house, the design, the finishes you pick and how long your city takes to approve the permits. After the site visit and the plans, you get a written bid, itemized line by line, with the price and the schedule before construction starts.
