◆ From the Founder
You deserve a contractor who treats your home like their own.
I started Ethos Building Group because I saw too many homeowners get burned — unclear scopes, hidden costs, crews that disappeared. That's not how we operate.
Every project we take on gets a clearly defined scope before a single nail is driven. You get daily progress updates, direct access to your Project Manager, and a team that shows up the same way every day: professional, accountable, and focused on the result.
We build in the South Bay because this is our community. When we finish your project, we want you telling your neighbors about us — and that only happens when the work is done right.

◆ The Client Experience
What it's like to work with us.
From the day you sign to the day we hand over the keys, here's what you can count on from Ethos Building Group.
One point of contact
Your dedicated Project Manager handles everything — questions, updates, scheduling, and problem-solving. You always know exactly who to call.
Daily progress logs
Every day work is active on your project, you receive a written log: who was on site, what was completed, and photos of the progress.
Clean, professional crew
Our crews respect your home. Clean job sites, no profanity, no chaos. We operate like professionals because that's the standard we hold ourselves to.
Organized from day one
Selections, schedules, permit timelines — all tracked and communicated before they become issues. You should never have to chase us for an update.
We honor our commitments
When we tell you something gets done by a certain date, we mean it. And if anything changes, we tell you immediately — not after the fact.
◆ Our Team
The people behind every project.
◆ Our Process
From first call to final walkthrough.
Every project follows the same disciplined path. Here's exactly how we move from inquiry to completion.
Free Consultation
We meet at your property, walk the scope, and understand your goals. No pressure, no obligation.
Scope & Estimate
We build a detailed line-item estimate. You know exactly what you're getting before anything is signed.
Permits & Prep
We handle city submissions, plan checks, and HOA coordination. Everything in order before we break ground.
Construction
Daily logs, progress photos, and direct PM access throughout. Clean site, organized crew, zero surprises.
Final Walkthrough
We walk the project together and close the punch list. The job isn't done until you're fully satisfied.
◆ What Sets Us Apart
This isn't the typical contractor experience.
◈Daily progress logs
Photos and a written summary sent each day work is active on your project.
◈Direct PM access
Your Project Manager is reachable throughout the build — no middlemen, no message queues.
◈Permit-ready process
We manage city submissions, plan checks, and all required inspections in-house.
◈Clean job site standard
Enforced as company culture on every project, every day.
◈Line-item estimates
You see a full scope and cost breakdown before signing anything.
◈Zero punch-list close
We don't consider a project finished until the punch list is at zero.
◆ Core Values
The standards we hold ourselves to every single day.
◈Structured Scopes
Every project starts with a clearly defined scope before construction begins. No ambiguity, no assumptions.
◈Clear Communication
Daily logs, progress photos, and direct PM access. You're never left wondering what's happening on your project.
◈Clean Job Sites
We enforce clean, organized job sites as a company standard — not something we do when clients are watching.
◈Honest Pricing
Realistic line-item estimates. No lowball bids to win the job and no surprise change orders once it starts.
◈Built to Last
We build for long-term durability and real property value — not just to pass inspection and move on.
◈Full Accountability
We own the schedule, the quality, and the outcome from day one through the final walkthrough.
What types of projects do you take on?+
Residential remodels — kitchens, bathrooms, full-home renovations — ADU construction, room additions, and specialty safe rooms. We work throughout the South Bay and greater Los Angeles County.
Do you offer free estimates?+
Yes. We offer a free on-site consultation to review your goals, walk the property, and discuss scope and budget before anything moves forward.
Do you offer financing?+
Yes. We offer 3rd party financing options for qualifying projects.
How long does a project take?+
It depends on scope. A kitchen remodel typically runs 6–10 weeks. An ADU can take 4–8 months from permits to final inspection. We provide a realistic phased schedule after reviewing your site.
Are you licensed and insured?+
Yes. Ethos Building Group holds California CSLB License #1152661 and carries general liability and workers' compensation coverage on every project.
Do you handle permits and HOA approvals?+
Yes. We manage the full permit process — city submissions, plan checks, required inspections — and coordinate HOA approvals where applicable.
Can I live in my house during a remodel?+
In most cases, yes. It depends on which areas are affected. We sequence the work to minimize disruption and discuss occupancy logistics during the planning phase.
How do change orders work?+
Any scope change is documented in writing and approved by you before work proceeds. We explain the cost and timeline impact clearly — there are no surprises on your final invoice.
Can I get a ballpark before committing?+
Yes. After a brief site visit and conversation about your project, we can provide a general budget range. A formal line-item estimate follows once we've fully defined the scope together.
Do you offer design-build or work off existing plans?+
Both. We can build from your architect's drawings or connect you with design resources if you're starting from scratch.
What is your warranty?+
We stand behind our work. We offer a workmanship warranty on completed projects and will return promptly to address anything that isn't right after we leave.
What areas do you serve?+
Manhattan Beach, Hermosa Beach, Redondo Beach, Torrance, Palos Verdes Estates, Rolling Hills, Rancho Palos Verdes, Gardena, Lawndale, Long Beach, and surrounding communities throughout LA County.
