How We Work

We start with your vision and move step-by-step toward a finished room that works for your family and your home.

Plan Your Addition

We listen to what you need. Bedrooms, offices, and bonus rooms all start with understanding your lifestyle and how the new space fits into your home.

Los Angeles homes sit on tight lots. We check setbacks, easements, and local zoning to ensure your addition works with your property and the neighborhood.

Secure Permits and Approval

We handle the paperwork so you don't have to. Building permits in Los Angeles require detailed plans, structural calculations, and city review. We submit everything correctly the first time.

Permits protect your investment and ensure the work meets code. It's non-negotiable for room additions in Los Angeles.

What's Involved: The Building Process

1

Set Up the Site

We protect your existing home, set up work zones, and arrange materials so building stays organized and safe.

2

Build the Foundation

A solid foundation is the base for everything. We dig, pour concrete, and ensure proper grading for your Los Angeles lot.

3

Frame and Roof

Framing creates the room's structure and shape. Once the roof is on, we're protected from weather while rough-ins begin.

4

Run Utilities

Electrical, plumbing, and HVAC lines are run behind walls. All work is inspected by the city to meet code.

5

Close and Finish

Drywall, paint, flooring, and trim bring the room to life. Doors and windows complete the enclosure.

6

Final Inspection

The city inspector walks through to confirm the work is complete and meets code. You get your certificate of occupancy.

You'll always know what's happening next—and when.

Why It Matters

Room additions and major construction carry risk if done wrong. Permits, inspections, and expert execution protect your investment and your family.

Permits Protect Your Home

Unpermitted work voids insurance coverage and creates problems when you sell. Los Angeles city requires permits for all room additions, structural changes, and utility work.

We submit complete plans, secure approval, and work with city inspectors. Your finished room comes with a certificate of occupancy—proof that the work is legal and complete.

Build for California Climate

Los Angeles heat, dry air, and occasional seismic activity shape how homes must be built. Proper insulation, ventilation, and structural reinforcement ensure comfort and safety.

Energy code compliance also saves you money on utilities. We build additions that stay cool in summer and meet current California Title 24 standards.

What is an ADU and is it legal in Los Angeles?

An accessory dwelling unit (ADU) is a separate, self-contained home on your property. ADUs are legal in Los Angeles. You can build a backyard ADU, garage ADU, or convert an existing structure, provided it meets zoning and parking rules.
