Los Angeles homeowners choose New Dawn Construction for major home extensions because the work demands a licensed, locally experienced builder. We are a licensed general contractor (CA License #1087088) with over 15 years in the field and 1,000+ projects across LA County. Our design-build approach gives you one team, one point of contact, and one standard of quality from start to finish.
From permits to final finishes, we provide a turnkey room addition service that LA families trust. Your upgrade should feel like a new beginning, not a disruption. Our track record, clear budgets, and inspection-ready work reflect what homeowners value most: reliability, craftsmanship, and a process that stays on schedule.
Proven Experience and Licensing You Can Rely On
Credentials matter when you are adding to your home. We hold CA License #1087088 and have completed more than 1,000 projects across LA County over 15 years. A design-build general contractor manages your entire project from concept through completion. That means one point of contact and one team responsible for quality and timing.
This single-source model lets our team move faster and more accurately than a multi-vendor setup. Choosing an experienced builder is not just a preference — it is a safety and compliance requirement in a complex jurisdiction like LA. Learn more in our LA contractor verification guide.
Comprehensive Full-Service Construction Approach
Homeowners who want minimal stress choose our full project coordination model. We handle everything — from feasibility and architectural planning through permitting, trade management, inspections, and post-construction support. You never have to coordinate between designers, engineers, and subcontractors. A single point of contact reduces risk, prevents scope gaps, and keeps communication clear at every phase.

Expertise in Permits and Local Regulations
In LA County, almost all major work requires formal permits and multiple inspections. This includes ADUs, garage conversions, and room additions. We manage the paperwork, plan checks, timelines, and city communication so your project keeps moving. A building permit is an official approval from local government that allows construction to begin after plans meet zoning and safety codes.
The permit process typically flows: pre-application → plan submittal → plan check → corrections → permit issuance → rough inspections → finals → certificate of occupancy. To understand your jurisdictional requirements, try our quick Permit Checker. For more details, see our LA permitting guide.
Customized Design and Craftsmanship Excellence
A major extension should feel original to your home — not tacked on. Our designers and artisans tailor each addition to match your neighborhood style and lot. We blend period details in Beverly Hills and maximize compact lots in Sherman Oaks. From custom layouts to one-of-a-kind finishes, every line and joint aims for harmony and everyday utility.
Craftsmanship highlights include:
- Architectural millwork that ties old and new spaces together
- Built-ins and cabinetry with furniture-grade finishes
- Crown molding, wainscoting, and period-accurate trim profiles
- Entertainment wall units and AV-ready niches
- Custom closet systems and space-optimizing storage
- Hand-finished stair components and railings

Transparent Budgeting and Timeline Management
Clear budgets mean you know what the project costs upfront. We provide detailed estimates that outline all major line items, so mid-project surprises are rare. Typical costs in Los Angeles: ADUs run roughly $150,000 to $400,000+. Room additions generally cost $100,000 to $300,000. Garage conversions are usually less. Kitchen remodels often take 5 to 10 weeks. Major structural additions take 12 to 16 weeks, with permits adding about 2 to 4 weeks.
Sample extension timeline (typical ranges):
- Design and engineering: 3–6 weeks
- Permitting and plan check: 2–4+ weeks (jurisdiction-dependent)
- Site prep and structural: 4–8 weeks
- Rough MEP and inspections: 3–5 weeks
- Finishes and punch list: 3–6 weeks

Value-Driven Solutions Tailored to Los Angeles Lifestyles
LA trends favor indoor-outdoor living, flexible ADUs, and smart upgrades to kitchens and bathrooms. Mid-range bathroom remodels in Los Angeles often recover 60 to 70 percent of their cost at resale. Garage-to-room conversions can add usable square footage without pouring a new foundation.
Think retractable glass walls that connect your living room to a covered patio. Or a spa-style primary bath to anchor a new suite. These are value-forward choices that turn extensions into high-ROI upgrades. For more ideas, see our guide to renovations that boost home value.
