ADU Construction in Sacramento: Build Smart, Build Local

Thinking about adding an ADU to your property in Sacramento? With housing demand on the rise and zoning laws more ADU-friendly than ever, now is the perfect time to invest in your space and increase your property’s value. At GBG Construction Inc, we specialize in ADU construction in Sacramento and surrounding areas—helping homeowners turn unused space into income-generating or family-friendly living units.

What is an ADU?

An Accessory Dwelling Unit (ADU) is a second, independent living space located on the same property as a single-family home. It includes its own kitchen, bathroom, and sleeping area. ADUs go by many names: in-law units, granny flats, backyard cottages—no matter what you call them, they offer flexible housing solutions for families, guests, or renters.

Types of ADUs

Sacramento homeowners have several options when it comes to ADU designs:

  • Detached ADU: A standalone unit built in your backyard.

  • Attached ADU: Shares a wall with your main house but has a separate entrance.

  • Garage Conversion: Transforms your existing garage into a fully functioning living space.

  • Junior ADU (JADU): Built within your existing home, typically up to 500 sq ft.

Whether you're building from the ground up or converting an existing structure, there’s an ADU solution to match your needs.

Sacramento Zoning & Permitting for ADUs

The City of Sacramento has made it easier than ever to build ADUs. Most residential lots are eligible for at least one ADU and one JADU. Common zoning and permit guidelines include:

  • Setbacks: Typically 4 feet from side and rear property lines.

  • Height limits: Vary by neighborhood (16–20 feet on average).

  • Parking: Usually not required if near public transit.

  • Owner-occupancy: No longer required for newly built ADUs.

At GBG Construction Inc, we handle the entire permit process—so you don’t have to worry about navigating local red tape.

Benefits of Building an ADU in Sacramento

Building an ADU is more than just a construction project—it’s a smart, long-term investment. Here’s why:

  • Rental Income: Generate monthly cash flow by renting out your ADU.

  • Multigenerational Living: Keep family close while maintaining privacy.

  • Home Value Boost: ADUs significantly increase your property’s resale value.

  • Sustainable Housing: ADUs are energy-efficient and reduce urban sprawl.

  • Affordable Expansion: Compared to buying a new home, it’s a cost-effective way to grow.

How Much Does an ADU Cost in Sacramento (2025)?

As of 2025, the average cost to build an ADU in Sacramento ranges from $150,000 to $300,000 depending on:

  • Type (garage conversion vs. new construction)

  • Square footage

  • Utility connections

  • Site conditions and finishes

Garage conversions tend to be the most affordable, while detached units with custom finishes are on the higher end.

Timeline for Planning and Building an ADU

Here’s a rough timeline for a typical ADU project:

  • Planning & Design: 1–2 months

  • Permitting: 1–2 months

  • Construction: 4–6 months

That means from first meeting to move-in ready, you’re looking at around 6–9 months total with the right contractor.
