Local ADU Regulations in Saratoga
Below is an overview of ADU regulations in Saratoga. If you need more details about how these guidelines apply to your property, reach out to us to connect with an ADU expert.
Where ADUs Are Allowed
ADUs are typically permitted on properties designated for residential use, though there may be exceptions. Your property must have an existing or planned single-family home or a multi-family building, such as a duplex, triplex, or apartment complex. Contact us to determine if your property is eligible for an ADU.
Minimum Lot Size
There are no minimum lot size requirements—any property, regardless of its dimensions, may qualify for an ADU.
Number of ADUs Allowed
Single-family homes can typically have one or two ADUs. Multi-family properties may be eligible for multiple ADUs depending on the number of existing units and the type of ADU constructed. Get in touch with our team to find out how many ADUs your property can accommodate.
Parking Requirements
Conversion and junior ADUs generally do not require additional parking. However, attached and detached ADUs usually need at least one parking space unless an exemption applies. Reach out to us for expert advice on Saratoga’s ADU parking requirements.

ADU Builder Saratoga FAQs
How long does it take to build a backyard cottage or in-law unit in Saratoga?
Most projects are completed in 9 to 14 months, depending on site conditions and customization. This includes 1–2 months for design, 3–5 months for permitting and reviews, and 4–6 months for construction. Homes on larger or hillside lots may require more time due to grading or utility considerations.
What’s the typical cost to build a compact home on my property?
Construction costs in Saratoga generally range from $500 to $550 per square foot, reflecting the city’s emphasis on quality and design. A 750 sq. ft. guest house or granny flat might start at $400,000, with larger custom units often exceeding $600,000. Additional expenses include permits, site work, and utility upgrades.
Can the new living space use the same utilities as the main house?
Yes, most secondary homes are connected to existing water, sewer, and electrical systems. If the space will be used for rental or separate occupancy, independent meters are optional but can be useful. For older homes, electrical panels or plumbing systems may need upgrades.
Are there energy-efficiency incentives for building these units?
Yes. Homeowners can take advantage of BayREN rebates, along with programs for solar panel installation, EV charging, and appliance upgrades. New units must comply with California’s Title 24 energy code, and structures under 750 sq. ft. are usually exempt from local impact fees.
Why are Saratoga residents building in-law suites or backyard homes?
These additions are ideal for multigenerational living, guest accommodations, or creating a quiet office or studio. They allow homeowners to expand usable space without altering the primary residence—and can also provide passive income if rented long-term.
Is there growing interest in secondary living spaces in Saratoga?
Yes. With high home values and large lot sizes, many Saratoga residents are adding garage conversions, detached garden cottages, or private suites to better accommodate family or plan for future living needs.
What kinds of architectural styles are common for these units?
Designs often reflect the style of the main residence, including Mediterranean, Craftsman, or contemporary farmhouse. Popular features include open layouts, vaulted ceilings, premium finishes, and outdoor elements like patios or courtyards.
Where can I find guidance on local requirements and permitting?
The City of Saratoga Planning Division provides zoning info, design guidelines, and permit resources online. You can also schedule a pre-application meeting to get help assessing your site’s potential and streamlining the review process.
How do small dwellings affect neighborhood character in Saratoga?
With the city’s design standards and lot-size requirements, these homes are built to complement existing properties. Saratoga requires setback, height, and privacy regulations to ensure secondary units blend in with their surroundings and maintain the area’s tranquil, low-density feel.
Do I need to provide additional parking for the new space?
It depends. If the new home is within ½ mile of public transit or replaces a garage, no additional parking is typically required. Otherwise, one off-street space may be necessary depending on the property layout.
