In the quiet streets of North Hills, near Northridge, a homeowner had a vision: turn their single-family home into a property that could create real income and long-term value.

The plan?
A modern two-story detached ADU — with two separate living spaces, built right in their own backyard.

Building the Dream

The project was ambitious:

  • A 1,200 sq ft, 3-bedroom, 2-bathroom home on the ground floor (an SB9-compliant unit).
  • An 800 sq ft, 2-bedroom, 1-bathroom home on the second floor.

Each unit would feel like a true home — private, comfortable, and finished with modern details that today’s renters expect.

Designed for Independence

This wasn't just an addition.
Each unit got its own:

  • Separate address
  • Own LADWP electric meter and account
  • Individual mailbox
  • Separate trash service

No sharing utilities. No confusion.
Just clean, independent living spaces — exactly what the city (and future tenants) want.

Quality That Shows

From the start, the owner focused on quality craftsmanship:

  • Modern kitchens with quartz countertops
  • Designer bathrooms with stylish tile work
  • Energy-efficient windows
  • Solar panels for huge electricity savings
  • Fresh landscaping that made the property feel brand new

Every detail was chosen carefully — blending style with long-term durability.

Breaking Down the Costs

Item Cost
Construction $420,000
Architectural plans $20,000
City permits and fees $30,000
Landscaping and extras $40,000
Total investment $510,000

The Payoff

Today, the property stands out on the block.
The two units offer strong rental income, solar keeps utility bills low, and the value of the entire property has jumped dramatically.

This North Hills/Northridge ADU project shows what's possible with the right plan, great design, and excellent construction.

If you're thinking about adding an ADU in Los Angeles or anywhere in the San Fernando Valley, take this story as proof:
It’s worth it.
