Accessory Dwelling Units (ADUs) have made homeownership far more accessible to Los Angeles residents. Between 2017 and 2022, over 25,000 ADUs have been approved for construction in LA, creating more opportunities for affordable housing. ADUs also allow homeowners to add more living space to their property, which they can use for themselves or rent out for additional income.
The existence of pre-approved plans, the relaxing of some building restrictions, and the ease of working directly with designers and architects can make it easier for you to expand your LA home.
One of Minix Home pre-approved plans might work for you, so keep reading to learn more about LA City’s Standard Plans Program, the pros and cons of choosing a pre-approved standard plan, and how to go about building a pre-approved ADU in the city of LA.
Building a Pre-Approved ADU Plan in Los Angeles: How Does it Work?
In response to California’s housing crisis, Los Angeles has allowed professional architects, designers, and ADU experts (like Cottage) to submit standard ADU plans to the Los Angeles Department of Building and Safety (LADBS). These plans are then pre-approved and made available to homeowners under the LADBS Standard Plan Program.
These plans come in a variety of types, styles, and sizes and are already approved by the City of Los Angeles. This “pre-approved” status can mean significantly shorter review and approval times. Not only that, but homeowners can work directly with the original architects and designers for guidance on how to build out these plans and in some cases, get assistance with any plan modifications and the actual construction process.
Let’s take a closer look at the advantages of using a pre-approved plan.
The Benefits of Using the LADBS Standard Plan Program
There are a number of advantages to using the LADBS Standard Plan Program:
- Save time and money
With a pre-approved plan, you’re likely to cut costs and enjoy a more convenient construction process.
- Streamline the permitting process
All LADBS standard plans are compliant with building, residential, and green codes, so you can obtain permits and plan checks quickly.
- Ensure a hassle-free project
All you’ve got to do before starting to build an LADBS pre-approved plan is review it against the conditions of your building site, such as foundation requirements and zoning compliance, and get the required permits.
While there are certain benefits that come along with using an LADBS Standard Plan, keep reading to explore some disadvantages of taking the pre-approved route.
Drawbacks of Using Pre-Approved ADU Plans: Are They Right for You?
While pre-approved plans come with several advantages, there are a few factors you should consider when choosing how you want to build your ADU:
- Pre-approved plans aren’t a one-size-fits-all
Not all plans are right for all properties. If you opt to use a pre-approved plan, you’d still need to go through the required checks to ensure the plan can be built on your lot. You may require some adaptations.
- Changes to your plan require further review
Room for customization is limited with a pre-approved plan; you can change windows and door types, sizes and colors, and also rotate floor plans. Minimal changes will allow you to maintain the pre-approved status, but larger changes to the floor plan are usually not permitted. Any changes would need to be reviewed and approved by building authorities, adding more time to the length of your project.
- Pre-approved plans aren’t good to go off-the-shelf
A pre-approved plan is not pre-permitted. You’d still need to carry out site-specific calculations before starting out and, all things considered, your best bet is to pick a plan that is closest to your vision and site needs and work off of that.
While considering the pros and cons of building out a pre-approved plan, you should also be aware of some of the requirements and regulations that govern ADU construction in the city or LA.
What to Consider When Choosing a Pre-approved ADU Plan in Los Angeles
There are a few things you need to keep in mind before choosing a pre-approved plan and setting out to build your ADU:
- Zoning
You may be eligible to build one ADU and one Junior ADU (JADU) on your property only if it has been zoned for single or multi-family use.
- Size and height
In the city of LA, detached ADUs may be up to 1,200 sq.ft. and JADUs may be up to 500 sq.ft.
If you have an existing primary dwelling on your property, an attached ADU may be up to 50% of its square footage.
ADUs within 200 ft. of a Scenic Highway cannot exceed a height of 18ft., while 25 ft. is the standard height allowance.
- Rental period
While long-term rentals are allowed, you cannot rent out your ADU for a period of fewer than 30 days.
Specific regulations around zoning, size, setbacks, parking, owner occupancy and other watch outs specific to LA can be explored in greater detail with the expert guidance of your architect or designer, but now that you know the basic requirements to build an ADU in LA, let’s explore the different plans available under the LADBS Standard Plan Program.
Designer-Owned Plans Available Under the LADBS Standard Plan Program
As of early 2023, there are 66 standard plans that have been pre-approved by the LADBS, and 4 pending approval. These plans, which have been submitted by around 30 different architects, designers, and ADU construction firms, vary in size, type, style, and price, and cater to a variety of aesthetics. Some plans have been submitted by companies that handle the whole process for you, from contract to construction. Other plans don’t come with expert guidance and require you to do some of the work yourself, so choose wisely!
