Maybe, a duplex ADU is something entirely new to you, so it’s a good idea to shed some light on the topic. Essentially, a duplex ADU is an accessory dwelling unit added to an existing duplex (or two dwelling property) to create a three-unit property. It is its own separate, private dwelling, similar to the other two units. As such, it fits neatly into the multi-family ADU category.
It’s easy to understand the surging demand for these properties throughout Orange County. First, they’re an excellent investment, maximizing aggregate rental income and consequently, ROI. But there’s another advantage to consider – Adding a duplex ADU generally enhances overall property value, which definitely boosts the bottom line should you sell.
John Christopher Construction is uniquely positioned to help owners maximize the benefits accruing from a duplex ADU. We’re among Orange County’s most experienced ADU builders, with a thorough understanding of both structural design and regulatory compliance. This gives us a big edge over our competitors, who may be much less familiar with the territory.
What Is a Multi-Family ADU?
To understand where these properties fit on the legal landscape, it’s important to know the legal definition of a multi-family. To qualify as a multi-family structure, a property must occupy one lot and consist of two or more attached dwellings. Within this framework, a multi-family ADU is distinct from a detached ADU (a separate, stand-alone structure) and a conversion ADU, which typically is garage conversion, storage facility, or other un-utilized space transformed from its original form into an ADU.
Recent regulatory updates have expanded the possibilities for multifamily lots. SB 9 allows single-family-zoned properties to be divided into two lots. Owners can build a maximum of two primary units on each newly created lot.
SB 1211 permits the building of a maximum of eight ADUs on a lot with a multifamily structure. However, the number of ADUs cannot exceed the current number of multifamily units. All in all, these two Senate bills expand the opportunities offered by multi-family ADUs.
Duplex ADUs Explained
Multi-family, duplex ADUs epitomize versatility. The original duplex structure may consist of two units stacked vertically, or the units may be positioned horizontally in a side by side arrangement. Either configuration offers owners significant benefits. As previously mentioned, two rentable units instead of one increases rental income potential. Furthermore, the extra unit allows for convenient multigenerational living while maintaining privacy for all occupants. Many variations are available to owners, including the popular ADU over the garage and detached unit combo. The possibilities are all the more enticing when you consider Orange County’s already high land values, which an ADU addition will undoubtedly boost. Definitely a savvy move from an investment perspective. The good news is, John Christopher Construction can make it happen for you now.
Benefits of Duplex & Multi-Family ADUs
While ROI maximization is a clear-cut benefit of duplex and multi-family ADUs, there are other advantages to consider. For one thing, as comparatively small dwellings, these units provide affordable housing. Plus, they offer property value enhancement and functional versatility, with these units serving as guest homes, rentals, offices, and blended living solutions.
California Regulations & Compliance
California regulations and compliance rules set important parameters for multi-family ADUs. Among the most important are the following: Minimum size (150 sq ft), maximums for studio/1-bed (850 sq ft) and 2+ bedrooms (1,000 sq ft). Additionally, parking is often reduced/waived near transit areas. And finally, there’s an allowance of 2 detached ADUs on multifamily properties (and more depending on unit count).
The complexity of the regulation and compliance environment underscores the need for an experienced proven contractor like John Christopher Construction to take the reins. Thoroughly familiar with the regulatory landscape, we navigate the environment with unsurpassed efficiency. The upshot? We get it done on time and on budget.
Design & Build Considerations
When constructing an ADU, John Christopher Construction considers many factors on the road to excellence. The most important of these are: lot size and layout constraints, privacy and soundproofing between duplex units, the matching exterior aesthetics with that of the main residence, and the implementation of separate utility hookups (plumbing, electrical). It all adds up to structural perfection, reflecting John Christopher Construction’s widely acclaimed custom design-build approach.
