Accessory Dwelling Units (ADUs) are now among the most popular house additions in California, especially around the San Francisco Bay Area. As housing prices go up, lack of space, and changing family needs are becoming issues, homeowners are increasingly turning towards ADU building to realize the full potential of their homes. If you're considering construction of an ADU, here's the scoop — and how Aziz Construction, an award-winning ADU contractor, can assist.
What is an ADU and Why Are Bay Area Homeowners Constructing Them?
An ADU, or Accessory Dwelling Unit, is a second house unit constructed on the same site as a single-family residence. They may be a separate building, garage conversion, or basement unit. They're ideal for:
Generating rental income
Making room for aging parents or adult children
Constructing a home office or guest bedroom
ADU building needs have skyrocketed as a result of state law changes, such as eased zoning and faster permitting. The housing deficit prompted state and local governments to incentivize ADU construction — and now is the perfect time to begin your project.
Frequently Asked Questions Homeowners Are Considering
How much does it cost to build an ADU in California?
Pricing is different, but standard Bay Area ADU projects range from $100,000 to $300,000+, depending on size, materials, and whether detached or a conversion.
How long does an ADU take to build?
Standard ADU building projects run approximately 4 to 9 months. Aziz Construction reduces schedules by having design, permitting, and building under one roof.
What are ADU regulations in 2025?
California and San Francisco have revised ADU codes to provide increased flexibility in size (up to a max 1,200 sq ft), minimum parking requirements, and simplified permits. Our staff keeps abreast of local codes so you don't have to.
Prefab vs Custom-Built ADUs: What's Best for You?
While prefab ADUs include faster construction timelines, most San Francisco homeowners want custom ADU services for greater design incorporation and long-term appreciation. Aziz Construction provides tailored solutions — from idea to completion — to fit your unique lot, budget, and vision.
