Is it time for you to consider building an ADU?

ADUs are also seen as an environmentally friendly housing option. They typically require fewer resources to build and maintain compared to new single-family homes. Moreover, ADUs can contribute to more sustainable urban development by increasing density without the need for sprawling new developments. This can reduce the overall carbon footprint of housing in California.

Villa Homes is the largest ADU builder in California, offering 15-floor plans with customizable interior finishes. Well, for starters, most households in the United States are now 1 and 2 person households. Yet, most of our legacy housing stock, and even our new residential housing stock, is designed for families of 4 or 5 people. While their structural forms vary, ADUs share many common traits and face similar design and development challenges.

Managing Your ADU Project

They have earned the respect of many homeowners across Los Angeles, and it’s easy to see why. ADU regulations and building codes vary dramatically by city and state. Many cities limit ADU size to 50% of the main house square footage or set absolute caps (commonly 800-1,200 square feet).

For one thing, the fact that they’re secondary housing units on single-family residentially zoned lots puts ADUs into a unique category. ADUs also have some other distinguishing characteristics that help further define, differentiate, and distinguish them from other housing types. Get detailed bids from at least three contractors based on identical plans and specifications. The lowest bid isn’t always best—look for contractors who catch potential issues in your plans, suggest value engineering ideas, and provide clear timelines. Read online reviews but weight recent references more heavily.
