This Huntington Beach attached ADU will be used as another rental for this property.

It is an approximate 400 sq ft studio. We will be installing a murphy bed once it arrives which will save room in the unit when not being used as a bed.

The goal: create a functional rental on an existing single family rental property. Its a great way to add to your rental portfolio without having to purchase another property.

A garage conversion is the most under-appreciated ADU path in SoCal right now.

Here's the short version of what's involved on a typical OC or LA County job:
→ Confirm the existing slab is in usable shape, or plan for a partial repour
→ Frame in interior walls, a bathroom location, and a kitchen wall
→ New plumbing rough-in tied into the main sewer line
→ Electrical sub-panel, often a service upgrade on older homes
→ Insulation, drywall, finishes
→ Inspections at rough, then final
→ Certificate of occupancy

State law treats the conversion as ministerial, which means no public hearing and a 60-day permit clock under SB 543 once the application is complete.

Most of the homeowners I talk to don't realize a garage conversion is usually the fastest ADU you can build on a single-family lot.

This Costa Mesa backyard went from unused space to a fully livable ADU 👀

This detached ADU was designed with an open layout that makes the space feel bigger than the footprint.

Full kitchen. Dedicated living area. Natural light throughout.
Everything needed to make a compact ADU feel like a real home.

The project proposal came in around the mid-600 sq. ft. range, showing how much functionality can fit into a smaller build when the layout is done right.

That’s what good ADU design is really about — maximizing usable space without making it feel cramped.

Would you use a detached ADU like this for rental income, family, or a guest house?

Quick city spotlight: Lakewood ADU permits.

A lot of homeowners I talk to in Lakewood assume the city is going to be slow or restrictive on ADUs. Here's what we're actually seeing on jobs going through right now:
→ Lakewood spun up its AB 434 pre-approved plan program to hit the January 2026 deadline
→ Plan check has been running close to the SB 543 60-day window for ministerial ADU applications
→ City staff are familiar with the SB 1211 multifamily detached path for duplex and fourplex lots
→ They process garage conversions, attached ADUs, and detached new builds under the same ministerial track

Lakewood is not a city you have to fight to build in. The infrastructure is there. The staff knows the law.

If you own a single-family or small multifamily lot in Lakewood and you've been thinking about it, this is one of the easier cities to move a project through right now.

Small space. Big upgrade.

This Whittier ADU shows how much value you can add when the layout is planned right.

What started as extra space on the property became a full living unit with its own kitchen, bathroom, and private setup.

That’s why ADUs make so much sense for homeowners — they give you options.

Family space now. Rental potential later. Or both.

What would you use an ADU for?

This is what a backyard ADU can become 👀

At this Lakewood project, we turned open backyard space into a functional ADU designed to add real usable living space to the property.

A full kitchen. A bathroom. A private living area. Everything needed to make the ADU feel like its own home.

That’s the goal with a good ADU layout — not just adding square footage, but making the space actually work.

Would you build one for family or rent it out?

Backyard space, but make it usable 👀

This Signal Hill project added a 550 sq. ft. freestanding ADU in the backyard.

It’s being used as a flex space — part office, part entertainment area, part extra living space.

Not every ADU has to be a rental. Sometimes it’s about creating more room for the way you actually live.

Office? Guest space? Hangout spot?

How would you use it?

From carports and laundry space to a real living unit 👀

This Costa Mesa project turned two carports + a laundry room into a 470 sq. ft. ADU with 1 bed, 1 bath, a full kitchen, and living space.

What used to be overlooked square footage is now a functional home.

Clean, simple, and actually livable.

Proof that you don’t always need more land — sometimes you just need a better plan.

Would you rent it, keep it for family, or use it yourself?

A separate space, but still close to home.

This Whittier project added a 900 sq. ft. attached ADU with 2 beds and 2 bath.

The goal: create a functional living space for an elder family member while keeping everyone on the same property.

Private space. Shared property. More flexibility for the family.

That’s one of the biggest reasons homeowners build ADUs — not just rental income, but options.

Would you build for family or rental income?
