ADUs & Guest Houses

ADU Builder in Los Angeles

NEPSA Construction builds detached ADUs, guest houses, garage conversions, attached ADUs and junior ADUs across Los Angeles. We help you figure out what fits your lot, then build it from plans to move in, with one point of contact the whole way.

What’s included

An ADU, managed start to finish

Add space for family, aging parents or rental income. We coordinate the trades, utilities and city inspections so you are not managing a dozen contractors in your own backyard.

  • Detached ADUs and backyard guest houses
  • Garage conversions
  • Attached ADUs and junior ADUs (JADUs)
  • Utilities, framing and finishes coordinated for you
  • City inspections through final sign-off

Is it a fit?

Good reasons to build an ADU

  • Housing for aging parents or grown kids, close but separate
  • Rental income on the lot you already own
  • A guest house, home office or studio
  • Converting an underused garage into living space

Questions

Common questions

What types of ADUs do you build?

Detached ADUs and guest houses, garage conversions, attached ADUs and junior ADUs. On your free consultation we look at your lot and tell you which options make sense.

Can you tell me what fits on my lot?

Yes. That is the first thing we do. We visit, look at the lot, access and existing structures, and talk through what you want the space for before anything is drawn.

Do you handle the city inspections?

Yes. We coordinate inspections through final sign-off as part of the project.

Is financing available?

We are setting up project financing for larger builds like ADUs. Until then we offer clear, milestone based payment schedules. Ask when you request your estimate.

Where do you build ADUs?

Across the City of Los Angeles and communities within about 45 minutes of central LA.
