Built for performance.
Onyx approaches every investment property — ADU, addition, value-add remodel, or multifamily upgrade — through a development lens. Scopes are built to lift rents, reduce vacancy, and strengthen long-term asset value across Los Angeles.
A development-driven approach to construction
Investment properties require a construction strategy tied to performance — rent, NOI, absorption, and long-term valuation. In Los Angeles, where land is scarce and buildings vary widely in age and condition, the difference between a standard renovation and a development-grade improvement can shift a property's financial trajectory entirely.
Scopes built around financial outcomes
Before a single scope item is written, Onyx evaluates finish levels, layout efficiency, mechanical performance, and structural viability to determine where improvements will produce measurable returns. Construction must support the trajectory — whether that's rent lift, repositioning, refinance, or long-term stabilization.
Design-build aligned with cap rate expectations
Strategic design-build ensures budgeting, sequencing, and material specifications are tied to neighborhood rent profiles and investor return thresholds. The goal is durable, high-performing improvements — not over-finishes that don't pencil, and not shortcuts that create deferred maintenance.

The strongest income tool in Los Angeles
ADUs remain one of the most powerful investment instruments available to Los Angeles property owners. Detached ADUs, attached units, over-garage structures, and garage conversions allow owners to add rentable square footage without acquiring new land — and state law now enables additional units within underutilized spaces on multifamily parcels.
Onyx manages planning, engineering, feasibility, utilities, and full construction for ADUs across single-family and multifamily parcels — structuring every scope around income generation, tenant privacy, daylighting, and modern renter expectations in neighborhoods from Venice to Brentwood.

High-impact upgrades that lift rent and reduce vacancy
Value-add work targets improvements that shift the rent conversation — kitchens, baths, flooring, lighting, and system renewals that deliver outsized returns when executed cleanly and efficiently. These aren't cosmetic gestures. They're strategic investments in tenant attraction and unit longevity.
Exterior improvements — paint, stucco repair, lighting, fencing, upgraded entries — significantly enhance tenant perception and curb appeal. The goal is durable, predictable improvements that hold up through turnover cycles in Santa Monica, Culver City, Silver Lake, and the Westside communities where Onyx works most often.
What we build for investors
From single-unit turns to multifamily repositioning, every scope is aligned with the financial strategy behind the project.
Additions & Reconfiguration
Single-story and second-story additions engineered to seismic standards. New rooms, flexible layouts, and primary suites that increase bedroom count and rent potential across Los Angeles's older housing stock.
Multifamily Improvements
Common area upgrades, unit interior improvements, laundry, exterior lighting, and landscape — all phased around active tenancy to minimize downtime and maintain occupancy during construction.
Permit Navigation
Full coordination across LADBS, Planning, Public Works, and LADWP — including architectural plans, structural engineering, MEP design, Title 24, and expediting services to keep approvals on schedule.
Vacant Unit Turns
Accelerated improvement cycles for vacant units — ensuring properties return to market quickly and in rent-ready condition. Inspection batching and coordinated trades keep timelines predictable.
Cost Modeling
Detailed cost models built on site conditions, existing systems, structural requirements, and finish standards — aligned with pro forma assumptions before construction begins.
Reporting & Documentation
Weekly photo logs, schedule updates, cost tracking, inspector sign-offs, and change-order transparency. Documentation that supports refinancing, insurance, and long-term asset management.

Predictable budgeting for development planning
Investment construction prioritizes clarity and alignment with pro forma assumptions. Onyx provides detailed cost models based on site conditions, existing building systems, structural requirements, and finish standards — so owners can plan with confidence before committing capital.
From first conversation to stabilized asset
Onyx is most valuable at the beginning of a project — before design is locked and before budget is committed. The decisions made in the first weeks determine the outcome more than any single construction choice.
Evaluate the investment strategy
Before scope is discussed, we understand the financial goal — rent lift, repositioning, refinance, or long-term hold. The construction plan follows from that, not the other way around.
Build the scope and cost model
Site conditions, existing systems, structural requirements, and finish standards are evaluated and translated into a detailed cost model aligned with your pro forma assumptions.
Navigate permitting early
LADBS, Planning, and LADWP coordination begins at the planning stage — identifying utility constraints, required clearances, and potential upgrades before they create schedule or budget exposure.
Execute and deliver
Coordinated trades, phased sequencing, and weekly reporting keep the project on schedule — and units return to market in rent-ready condition, not on a timeline that surprises anyone.
Not sure where to start?
Most investors arrive with a financial goal, not a construction plan. Here's how Onyx matches strategy to scope.
"I want to add a rentable unit without buying new land"
Start with an ADU feasibility conversation. Detached, attached, over-garage, and garage conversion options all exist on most Los Angeles parcels — and Onyx will tell you which is buildable and what it costs to pencil.
"I want to lift rents and reduce vacancy time"
Start with value-add remodel planning. Kitchens, baths, flooring, and exterior improvements deliver the highest return per dollar spent — when scoped to the neighborhood rent ceiling, not beyond it.
"I want to increase the bedroom count"
Start with an addition or reconfiguration review. Second-story additions and floor plan restructuring can increase bedroom count and rent potential without expanding the footprint beyond zoning limits.
"I want to improve a partially occupied building"
Start with a phasing strategy. Onyx structures work around active tenancy — maintaining safe common areas, limiting disturbance windows, and keeping the property income-producing throughout construction.
"I want predictable budgets before I commit capital"
Start with a cost model. Onyx builds detailed estimates against site conditions and finish standards before construction begins — so your pro forma assumptions have a real number behind them.
"I want documentation that supports refinancing"
Start with a reporting agreement. Weekly photo logs, cost tracking, inspector sign-offs, and full change-order transparency support lender confidence and long-term asset management.
