About Jay Remodeling

ADU Construction Services by Jay Remodeling in Los Angeles

Jay Remodeling is a licensed and certified ADU contractor based in Los Angeles, California. Under California's updated ADU guidelines introduced in 2020, a single-family residence is now permitted to have two separate accessory dwelling units on the same property — one being a standard ADU and the other a Junior ADU (JADU). Jay Remodeling helps homeowners navigate this process, from design and permitting through to construction.

As an experienced accessory dwelling unit builder, Jay Remodeling handles a range of ADU types, including:

  1. Attached ADU — conjoined with the existing main unit
  2. Detached ADU — a fully separate structure from the primary residence
  3. Garage conversion ADU — converting an unused or old garage into a livable space
  4. Above-the-garage ADU — building a new unit over an existing garage
  5. Basement conversion ADU — transforming a basement into a new dwelling unit
  6. Junior ADU (JADU) — smaller units typically ranging from 450 to 500 sq. ft.

Whether a homeowner is looking for a backyard cottage builder, a granny flat builder, or a garage conversion contractor, Jay Remodeling offers services across these different ADU formats. The maximum size for an attached ADU under California state law is 1,200 sq. ft., or up to half the size of the existing home — whichever is smaller. Detached ADUs may be larger in size.

Building an ADU requires obtaining the appropriate permits from the local municipality and the Building & Safety Department. This typically involves submitting a master plan and floor layout design for approval. In Los Angeles, the permit approval process generally takes between 60 and 120 days, depending on the quality and completeness of the submitted plans. Jay Remodeling assists clients through this permitting process as part of their service.

Benefits of Adding an Accessory Dwelling Unit

There are several practical reasons homeowners in Los Angeles choose to build an ADU on their property. One of the most common motivations is the need for additional living space. A Casita, in-law suite, or granny flat can provide comfortable accommodation for extended family members such as parents, grandparents, or adult children.

Beyond family use, an ADU can also serve as a rental unit, providing a potential source of ongoing income. A garage conversion contractor like Jay Remodeling can also transform an underused garage into a functional home office — a separate, quiet workspace away from the main household.

From a financial standpoint, statistics suggest that more than 75% of southern California homes with ADUs benefit from increased property values. An accessory dwelling unit can raise a home's resale value by an estimated 50 to 60%, making it a worthwhile investment for many homeowners looking to improve their return when selling.

Permitting and Zoning Considerations

Zoning laws play an important role in determining what type of ADU can be built on a given property. If a lot is zoned for single-family residential use, homeowners are generally permitted to build and rent an accessory dwelling unit — even if a local homeowners association has restrictions in place. State law in California takes precedence in many of these situations.

A permit is always required before construction begins. Building without one would render the new structure illegal. Jay Remodeling works with clients to ensure all necessary documentation is submitted correctly, helping to avoid delays in the approval process.

For homeowners in Los Angeles considering a detached ADU builder, a JADU contractor, or any form of accessory dwelling unit construction, Jay Remodeling offers the experience and licensing to manage the project from planning through completion.

"We are two designers in the film business and hired Jason and Shane of JHandy Construction to build a two-story 800 - square foot ADU apartment on our property in Pacific Palisades. The project featured high-end finishes and required an exceptional level of craftsmanship and detail - Jason and Shane delivered beautifully. They were a pleasure to collaborate with: professional, communicative, and proactive in finding solutions throughout the process. Their team of subcontractors was excellent, the work was completed on time, and the project stayed on budget. They stand by their work and were always quick to respond after completion of construction - often on site the very next day. We highly recommend JHandy Construction to anyone seeking quality, artistry and integrity in their build. Deborah Evans Tom Foden"

"I have worked with Jason and his crew for years! Wonderful helpful experienced people. Kind and thoughtful. Everything from construction to touch ups and repairs. Local and trustworthy! Even did some construction on our business offices with them too. I've known them for 10 years now. Solid."

"When I first reached out to Jason and Shane, it was to do a small patio and deck. That turned into hiring them to finish a remodel and repair project started by another contractor. When I moved, I hired them again for a kitchen and bath remodel, and when heavy rains uncovered some major issues, they took care of securing and improving my house - from a new roof to interior structural work to finish work. They have excellent teams of subs working with them and stay on top of every detail. Their work is top-quality."
