Benefits of building an ADU in Historical

HPOZ Los Angeles 

What is a HPOZ zone in Los Angeles?

And should I build an accessory dwelling unit? 

Due to residents of Los Angeles being upset that their historic neighborhoods were being uprooted. As the city recognized the importance of preserving the architectural and cultural legacy of its neighborhoods, the City adopted the HPOZ Ordinance A Historic Preservation Overlay Zone, or HPOZ, is a zoning tool that protects and preserves neighborhoods composed of architecturally and historically significant structures. A type of historic district, HPOZs primarily protect single-family residential neighborhoods. In 1983, Angelino Heights was the city’s first HPOZ neighborhood.

The first step to designating an HPOZ is to prepare an historic context statement and survey, which outlines the historic, architectural, and cultural significance of a neighborhood and identifies contributing and non-contributing structures. Generally speaking, contributing structures date to the period of significance of the neighborhood and do not feature major alterations and additions that compromise the historic integrity. Conversely, non-contributing structures may have been heavily altered and/or constructed outside the period of significance. Now is a better time than ever to build an ADU in an HPOZ.

According to the state of California, an ADU is defined as, “An accessory dwelling unit with complete independent living facilities for one or more persons and has a few variations.” What exactly does that mean? It means that ADU’s are made for independent tenants that may vary in terms of size, design, bedrooms, bathrooms, and more. ADU’s can be custom built to any homeowner’s specifications while still following all regulations that the state of California hands down to builders. ADU’s go by a few different names. Some people call them granny flats, in-law units, backyard cottages, secondary units and more. No matter what you call them, ADUs are an innovative, affordable, effective option for adding much-needed housing in California.

California has an affordable housing problem. As rent prices skyrocket through the city, people are having trouble finding affordable places to live. By building an ADU,you are giving your future tenant a chance to have their own independent dwelling without paying the price of their own full sized home. ADU’s come in 1-3 bedrooms so even a whole family could rent one out. ADUs provide benefits for both society and individuals. ADU’s provide livable spaces but  with lower costs and quicker permitting processes than for larger, multi-family buildings. Because ADUs tend to be smaller than full size homes, and their amenities are more inexpensive. They provide more affordable housing options. Oftentimes, these units are the only rental housing available in older, predominantly single-family neighborhoods, making it possible for people from all walks of life to live in the area. 

Top 3 reasons to build  ADU in Historical

HPOZ Los Angeles 

Second source of income

Creating a second source of income is one of the greatest things you can do for your financial situation. Creating one that is passively earning you money is even better! Building an ADU is exactly what you should do if you want the best of both worlds. You can either rent out your ADU for short term or for the long term. Long term is more stable, while short term is less but provides 2-3x more monthly income for you. In the city of San Fernando you can rent your ADU as a short term rental for less than 30 days.

Improve your space

You can improve your space however you want to though. In the City of San Fernando there are many options available. Like a in-law unit, secondary unit, a backyard cottage, yoga studio, business address, or just a workshop. Anything you can dream up, we can build it in San Fernando.

Family Flexibility

Many individuals will want to convert their garage or build an ADU so they have space for their relatives to live when they come to visit or have a college student back for the summer. These are great alternatives to buying a bigger house or trying to move that college kid back into their own bedroom.

What should you keep in mind in the planning stage of your ADU?

Since January 2020 it has become much simpler to get plans approved by the city of Los Angeles HPOZ department .

The most tedious phase of building an Accessory Dwelling Unit or a garage conversion is the permit and planning process. This takes longer because you have to get plans approved by the city, by an architect, receive permits, and then finally sign them yourself. You’ll have to create, with the help of your general contractor, a “Site Plan”. This includes the proposed location, the size, parking, setbacks, existing structures, floor plans, elevations, utilities, and any other additional JADUs you want to build at the same time. In the city of Los Angeles depending on your zoning you can have multiple ADUs or JADUs. After getting approval from the architect you can sign the documents and get started with the build.


Once all paperwork is recorded the draftsman will submit complete plans with required structural and energy reports to the building and safety division for review. This process should take around 30-120 days, but the city San Fernando has been known to take their time. There is an expedited process, but it does cost a bit more.

Understanding Parking at your ADU

ADUs are required to provide 1 additional parking space. It doesn’t matter if it is covered or uncovered. The exception is if the ADU is located within ½ mile of public transportation. ADUs within HPOZ Los Angeles cannot have direct access to a garage if the proposed or existing garage of less than 3 spaces.

Setbacks are an important part of planning your ADU

Unit size has grown over the years, In January 2020 the maximum size of an ADU is 1200 square feet. The increased floor area of an accessory dwelling unit shall not exceed 50 percent of the existing living area. In HPOZs specifically, an ADU can be anywhere from 150-1200 square feet.

Setbacks must adhere to the state’s 4 feet rule from the side and rear of the yard. It also must remain 6 feet from the existing main dwelling. Existing accessory structures and single family homes that are converted into ADUs are exempt. So it’s worth it to see if you can do a garage conversion rather than build a brand new structure.

Title 24 in California

Title 24 is California building energy efficiency standers. California energy code is designed to reduce wasteful and unnecessary energy consumption in newly constructed buildings. The states energy commission updates the building standers every three years by working with public stakeholders.

All ADUs that are permitted after January 1st 2020 must comply with 2019 Title-24 standards.

New building energy standards will help reduce wasteful and inefficient consumption of energy. The new ordinate is specific about water heaters, high performance attics, walls and windows. Every set of plans will come with window schedule, this will be discussed in your meeting with our architect.

A JADU is known as a Junior Accessory Dwelling Unit and is an independent living space created through the conversion of an existing legally permitted bedroom. They are typically very small living units and are up to 500 sqft. You are allowed to add an efficiency kitchen and other necessities.
