What the middle of a job actually looks like

Most contractors only show you the finished photo. Here is the framing, the underlayment and the tile layout — the work you will never see again once the walls close up.

Our commitment

Homeowners do not get burned by bad framing. They get burned by surprise invoices, silent weeks, and work nobody agreed to. So we put it in writing.

How we can help

A San Diego general contractor for residential and commercial builds

Whether you are adding rental income with an ADU, buying back square footage with an addition, or turning over a suite for a new tenant, you get the same thing from us: a documented scope, a transparent cost breakdown, and a crew that shows up.

Our process

Four steps, and you know where you stand at each one

No mystery phases. Every stage ends with something in writing that you have seen and approved.

1

Consultation

We walk the site, listen to what you want out of the space, and talk honestly about what the property and the code will allow.

2

Feasibility & scope

We define the real requirements: structure, permitting path, utilities, and the approach that fits your budget.

3

Written estimate

You receive a line-item estimate with the scope spelled out. You read it before anything is ordered or scheduled.

4

Build & walkthrough

Execution with weekly photo updates, inspections coordinated on our end, and documented closeout when it is done.

Questions

What clients ask us first

Are you licensed and insured?
Yes. Alpha Advantage Home Builders Inc holds California contractor license #1153656 and carries general liability and workers' compensation coverage. We will provide current certificates on request before you sign anything.
What does SDVOSB mean for me as a client?
It means we are a certified service-disabled veteran-owned small business. For private clients it signals how the company is run. For public and prime-contractor work, it can also help you meet set-aside and subcontracting goals.
Do you handle permits and inspections?
We do. Permit requirements depend on scope and jurisdiction, and structural, electrical and plumbing work almost always trigger them. We coordinate submittals, schedule inspections, and manage corrections so you are not sitting at a counter downtown.
What does a written estimate actually include?
A line-item breakdown of scope, materials, labor and allowances, plus the assumptions behind the number. If something is excluded, it says so. You will not get a lump sum with no explanation.
How long does an ADU or addition take?
It depends on scope, permitting and site conditions. Bathroom remodels can run a few weeks. ADUs and second-story additions typically run several months once permits are in hand. We give you a phase-by-phase timeline with the estimate rather than a single optimistic end date.
What happens if something changes mid-build?
Nothing extra gets built until you approve it in writing. If a condition shows up behind a wall or you change direction, we issue a change order with cost and schedule impact, and work continues only after you sign it.
Do you take commercial and tenant improvement work?
Yes. Alongside residential renovation we handle ground-up commercial construction and tenant improvements, including turnovers on a landlord's schedule. Tell us the delivery date you are working against and we will tell you honestly whether we can hit it.
