Local ADU Regulations in Albany
Below is an overview of ADU regulations in Albany. For more details on how these rules apply to your property, contact us to get connected with an ADU expert.
Where ADUs Are Allowed
ADUs are typically permitted on residential properties, though some exceptions may apply. Your property must have an existing or planned single-family home or a multi-family building, such as a duplex, triplex, or apartment complex. Reach out to us to verify if your property qualifies for an ADU.
Minimum Lot Size
There are no minimum lot size requirements—any property, regardless of its dimensions, may be eligible for an ADU.
Number of ADUs Allowed
Single-family homes can generally accommodate one or two ADUs. Multi-family properties may allow multiple ADUs, depending on the number of existing units and the type of ADU constructed. Get in touch with our team to determine how many ADUs your property can support.
Parking Requirements
Conversion and junior ADUs typically 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 Albany’s ADU parking requirements.

ADU Builder Albany FAQs
How long does it take to build a secondary unit in Albany?
Most projects take about 8 to 12 months from start to finish. That includes 1–2 months for design, 2–4 months for city permits, and 4–6 months for construction. If your property is on a narrow lot or requires extra site prep, the timeline could be longer.
What’s the typical cost to build a compact second home?
Costs generally range from $450 to $500 per square foot, depending on the size, finishes, and whether you’re building from the ground up or converting an existing space. A 750 sq. ft. in-law unit may cost $340,000 or more, with larger dwellings pushing beyond $475,000. Utility upgrades and permit fees are also part of the overall budget.
Can the new living space share utilities with the main house?
Yes. Albany allows shared connections for water, sewer, and electricity, though some homeowners choose to install separate meters—especially if the space will be rented out. In older homes, upgrades to electrical panels or plumbing might be required to meet modern standards.
Are there energy-saving incentives or rebates available?
Yes. Homeowners may be eligible for BayREN rebates, solar panel incentives, and discounts on energy-efficient appliances and EV charging setups. All new construction must meet Title 24 energy codes, and units under 750 sq. ft. are exempt from local impact fees.
Why are more Albany homeowners building backyard cottages?
These smaller homes are a smart way to create flexible, affordable housing without leaving your property. Whether it’s for aging parents, adult children, guests, or passive income, they offer a thoughtful solution in a city where space is limited and housing costs are high.
Is there a strong local interest in building these units?
Yes. With rising rents and limited inventory, more residents are exploring the option to build small secondary dwellings—especially those looking for multi-generational living or extra rental income without selling or moving.
What kinds of styles or features are popular?
Designs often reflect Albany’s cozy, walkable feel. Homeowners are choosing modern studios, eco-friendly micro homes, and converted garages with features like open layouts, large windows, smart tech, and private entrances.
Where can I find help getting started?
The Albany Community Development Department provides resources including zoning information, design guidelines, and step-by-step permitting checklists. You can also request a pre-application review to go over your property’s feasibility and next steps.
Will a second unit change the look of my neighborhood?
Not likely. Albany has design and setback standards to ensure these homes are scaled to fit the lot and surrounding properties. When done thoughtfully, they blend in while gently increasing housing options.
Do I need to provide extra parking?
In many cases, no extra parking is required, especially if the unit is within ½ mile of public transit or part of a converted garage or basement. Otherwise, you may need to provide one off-street space, depending on the layout and location.
