ADUs

ADU is an accessory dwelling unit, a detached or an attached building that goes into a backyard or a side yard of an existing residence. ADUs are usually built as a guest house or extra living space on the property for rental purposes or as a long term investment.

ADUs are an extension of your property so it does increase your property value. However, the property tax goes up insignificantly by the amount of construction costs added to the base of your assessment value.

New ADU State Laws

On October 9th 2019, Governor Gavin Newsom signed a series of bills opening up ADU’s statewide. These bills went into effect on January 1st 2020 and dramatically loosened the restrictions for building ADUs throughout the state. The main purpose of these bills is to standardise the regulations for ADUs.

Remove minimum lot size requirements
Mandate setbacks to a maximum of 4 ft from side and rear property lines
Eliminate impact fees for units less than 750 sq. ft.
Place a 5 year moratorium on owner occupancy requirements
Allow up to 2 ADU’s in multi-family zones
Eliminate lot coverage requirements for units under 800 sq. ft.

While these new laws have done a great deal of work in standardizing the accessory dwelling unit requirements statewide, local jurisdictions still have a lot of ability to control the types of ADUs in their area. For instance, design requirements may still be a factor in specific locations. Feel free to reach out to your Mighty Buildings representative to check specific properties for their local requirements.

Factory Built Housing

Mighty buildings plan

Factory Built Housing is exactly what it sounds like. It is a program put in place by California’s Department of Housing Community Development to allow the assembly and construction of portions, or the entirety of a construction project be built offsite as a method to reduce cost and weather delays. Once onsite and installed, there is essentially no difference between a Factory Built House and a traditional built house. These units are inspected at the factory, but installations are inspected by the local jurisdiction.

All our designs are reviewed at the State level and come with a pre-approval at the authoritative housing jurisdiction level. This means that when the permit package is submitted to the local jurisdiction, they only review site specific details, such as the foundation, utility connections, and installation plan for the unit, creating less confusion and much quicker straight forward plan review.

For more information on the Factory Built Housing Program refer to this HCD Manual.

Why Build an ADU?

Mighty buildings plan

The best time to build is now. ADU’s are an investment for your property and provide financial security in a slow housing market or economic downturn. In fact, an ADU can be one of the safest investments you can make. It is a direct investment into your current property and during a downturn, it can increase the value of your property. In addition to the sizable increase to your property, you can gain the potential rental income, which gives you a steady flow of income during unprecedented times.

Assumptions:

  • + Purchase Price: $1,250,000
  • + Down Payment: 10%
  • + 30-year fixed
  • + 3.50% interest rate

Rates are historically low

Higher ROI than a traditional remodel
Multiple models to accommodate virtually any size yard

Benefits of ADUs?

Price vs cost

All our ADU's come complete with state of the art 3D printed technology, high end appliances, Anderson windows and doors, stone countertops, tankless water heater, central heating and air, and even solar panels. Mighty Buildings’ industry leading 10-year warranty shows our dedication to the quality of construction and craftsmanship. In comparison to other ADU units in the market without turn-key solutions, we truly believe you get the quality you pay for and in the end, you will save on the overall cost of your new ADU.

An end-to-end process

Our end-to-end service includes permitting, site evaluation, construction, delivery and setup, and financing. This saves you time and money as you don't have to get involved in the time consuming process of ensuring your new ADU is built to code. Our project managers and compliance officers guarantee that all the required documentation will be completed and filed in accordance to state and local guidelines.

Property Values

A recent University of Oregon study showed that an ADU can increase the value of your property more than 20% over a traditional full home remodel. In addition, you gain valuable additional living space that a typical remodel would not be able to provide.

Rental Income

One of the most sought after benefits of an ADU is the ability to rent it out and generate a steady monthly income. Unlike adding a guest room to your existing home, renters are separated from your main residence. This allows you to monitor and maintain the ADU without sacrificing your privacy.

Financing

Rates are currently at historic low levels and Mighty Buildings has several loan programs that can assist you in purchasing your new ADU. Even if you were planning to pay in cash, a short discussion with our financing team could provide valuable options.

ADU Laws

On January 1, 2020 a series of laws went into effect that revise and relax the laws governing ADUs. The new laws are intended to help address the housing shortage in California and make ADU development easier. For developers, investors and homeowners these laws will open up a range of investment possibilities.

MB tech advantages vs concrete 3D printing

Mighty buildings plan Mighty buildings plan

Mighty Buildings uses 3D printing technology and proprietary Light Stone Material such as reinforced concrete, as an alternative to conventional building materials. Beyond the structural and other physical properties, the material replaces several layers of material as it can work as structural, exterior, and interior material.

Our Light Stone Material eliminates cold joints between layers, which occur when the specific temperature and humidity requirements for proper curing of concrete are not met. We are able to achieve this due to the rapid solidification of our material under UV light, thus avoiding the structural issues when the material is solid and subjected to loads. This rapid curing also allows the LSM to print in horizontal layers without a supporting structure, meaning we can print walls, floors, ceilings and more.

Other important qualities of the material:

  • Fire resistant
  • Hydrophobic
  • Resilience

Mobile homes vs Modular

Mighty Buildings is considered a modular home builder which differs from traditional “mobile homes”. Mobile homes could serve a means of temporary housing solution whilst our 3D printing technology and unique composite materials are able to bring energy efficient buildings of a high quality and modern design to the market at a cheaper price point than traditional construction.

Modular construction is permanent real property and an appreciating asset. It serves as a long-term investment while mobile and manufactured homes will depreciate in value since they are not affixed to a permanent foundation.

Additionally, financing for modular construction works the same as traditional home or construction loan financing. Mobile homes are financed similar to other depreciating assets like RVs or boats.

  • High quality
  • Permanent real property
  • Appreciating asset
  • Long-term investment
  • Traditional financing applied
