Garage Conversions: Full structural reinforcement, insulation, and utility tie-ins to create legal “Granny Flats.”
Detached ADUs: Ground-up builds for rental income or multi-generational living.
Room Additions & Bump-Outs: Expanding bedrooms or adding a “California Room” (indoor-outdoor transitional space).

Title 24 Energy Upgrades:

Cool roof installations and high-performance insulation.
EV charging station installations and solar-ready electrical panels.
Permit Expediting: Managing the complex approval process through the LADBS (Los Angeles Dept. of Building and Safety) or various city-specific planning departments (e.g., Santa Monica, Culver City).
Common types of ADU – Accessory Dwelling Unit:
1. Detached ADU
This is a standalone structure separate from the primary home, usually located in the backyard.
Max Size: Up to 1,200 sq. ft.
(Standard in LA County).
Key Feature: Offers the most privacy and highest rental value.
2026 Update: Must include solar panels per updated California Building Codes for new detached construction.
2. Attached ADU
A unit that shares at least one wall with the primary residence. It is often a “bump-out” or an addition to the side or rear of the house.
Max Size: Limited to 50% of the primary dwelling’s living area, but the city must allow at least 850 sq. ft. (or 1,000 sq. ft. for 2+ bedrooms).
Key Feature: Often more cost-effective for utility tie-ins (plumbing/electrical) since it’s connected to the main house.
3. Junior ADU (JADU)
A specific category of unit built entirely within the “existing footprint” of a single-family home (e.g., a spare bedroom or an attached garage).
Max Size: Strict limit of 500 sq. ft.
Requirements: Must have its own exterior entrance and an “efficiency kitchen.”
Unique Factor: Can legally share a bathroom with the main house. Note: In 2026, JADUs generally still require the owner to live on-site, unlike standard ADUs.
4. Conversion ADU
The most popular type in Los Angeles, these involve transforming existing non-living space into a legal residence.
Common Sub-types:
Garage Conversions: Turning a detached or attached garage into a studio or 1-bedroom.
Basement/Attic Conversions: Less common in LA but viable for older homes with significant vertical space.
Accessory Structure Conversions: Converting old pool houses, workshops, or sheds.
Benefit: Often exempt from certain setback requirements if the existing structure was legally built.
5. Two-Story or “Over-Garage” ADU
A unit built on top of an existing or new garage (carriage house style).
Height Limits: Recent 2026 guidelines allow for heights up to 25 feet in certain transit-rich or multi-family zones in LA, making 2-story units more feasible.
Challenge: Requires significant structural engineering (bolting and shear walls) to support the weight and meet seismic codes.
We provide an end-to-end “Turnkey” ADU service divided into the following phases:
1. Pre-Construction & Feasibility
Before a shovel hits the dirt, the contractor must navigate the complex zoning laws of LA County or the City of Los Angeles.
Zoning Analysis: Checking the property via ZIMAS (Zone Information and Map Access System) to determine allowable ADU size, height limits, and setback requirements (usually 4 feet from side and rear property lines).
Utility Capacity Assessment: Determining if your current electrical panel (e.g., 100-amp vs. 200-amp) can handle the added load or if a separate meter is required.
Sewer & Septic Evaluation: Locating the main sewer line to determine if the ADU can gravity-feed or if an ejector pump is necessary.
2. Architectural Design & Engineering
The contractor manages the creation of the “Plan Set” required for city approval.
Architectural Blueprints: Designing the layout (Studio, 1-bed, or 2-bed) to maximize small-footprint living.
Structural Engineering: Necessary for “over-the-garage” builds or units on hillside lots common in the Hollywood Hills or Silver Lake.
Title 24 Energy Calculations: Ensuring the unit meets California’s strict energy efficiency standards (insulation, window ratings, and solar requirements).
3. Permitting & “Expediting”
A seasoned LA contractor acts as your representative at the LADBS (Department of Building and Safety).
Plan Check Management: Submitting plans and handling the “corrections” process where city engineers request modifications.
Coastal Commission Clearances: If the property is in a coastal zone (like Malibu or Venice), the contractor handles the extra layer of environmental permitting.
4. Structural Construction (The Build)
This covers the actual physical assembly of the unit.
Foundation Work: Excavation and pouring of a “slab-on-grade” or raised foundation.
Framing & Envelope: Building the skeleton of the unit using traditional timber or cold-formed steel.
Roofing: Installing “Cool Roof” certified materials to reflect heat, as required by LA code.
5. Specialized MEP (Mechanical, Electrical, Plumbing)
Sub-Metering: Installing separate meters for water and electricity if the unit will be a rental.
HVAC: Installation of “Mini-Split” ductless systems, which are the standard for ADUs due to their space-saving efficiency.
Solar Integration: Per the California Building Code, almost all new detached ADUs must include a solar photovoltaic system.
6. Interior Finishing & Compliance
Space-Saving Finishes: Installing pocket doors, built-in storage, and stackable laundry hookups.
Fire Safety: Installing required fire sprinklers (if the primary residence has them or if required by local fire distance codes) and smoke/CO2 detectors.
Hardscaping: Creating a private entrance or path for the ADU to separate it from the main house.
Fix & Flip Construction Services:
These services are focused on ROI (Return on Investment)—prioritizing high-impact visual upgrades and essential structural “deal-killers.”
1. Rapid Interior Value-Add
Cosmetic Overhauls: Level 5 drywall smoothing, trending paint palettes (interior/exterior), and modern baseboard/trim packages.
Kitchen/Bath “Pulls”: Rapid replacement of cabinetry, countertops, and fixtures with high-style, mid-tier materials (e.g., Prefab Quartz and Shaker cabinets).
Flooring Upgrades: Installation of durable, wide-plank Luxury Vinyl Plank (LVP) or engineered hardwoods.
2. Critical Systems & “The Big Three”
Lenders and buyers’ inspectors focus on these; fixing them is non-negotiable for a successful flip:
Roofing: Repair or replacement to ensure the property is insurable and qualifies for traditional financing (FHA/Conventional) for the end-buyer.
Electrical/Plumbing: Upgrading legacy “Knot and Tube” wiring or galvanized pipes to Copper/PEX to pass 2026 code inspections.
HVAC: Replacing aged units with energy-efficient heat pumps (standard in 2026 LA climate goals).
3. Curbside Transformation
Drought-Tolerant Landscaping: Utilizing DG (Decomposed Granite), succulents, and drip irrigation to meet LA water conservation standards while boosting curb appeal.
Exterior Skin: Patching stucco, installing modern wood-look siding accents, and replacing windows with dual-pane vinyl for energy compliance.
4. “The Force Multipliers”
Garage-to-ADU Conversion: The most common flip strategy in LA to significantly increase the “Exit Price” by adding a legal second unit.
Open Floor Plan Conversion: Removing non-load-bearing walls (or installing LVL beams) to create the “Great Room” look buyers demand.
