Frequently Asked Questions
Answers to common questions about ACSIOM homes — cost and budget, site fit, Smart Living and privacy, service area, permits, and how pricing and deposits are handled.
Cost & Budget
How much does a 750-square-foot ADU cost in the Bay Area?
The total cost varies based on site conditions, foundation requirements, utility connections, permitting requirements, construction access and the selected home configuration. ACSIOM’s current 749-square-foot, two-bedroom, two-bath model, ACSIOM ADU 749-26, starts at $349,000 based on the standard model scope.
The final project budget may also be affected by foundation and site preparation; water, sewer and electrical connections; electrical service upgrades; grading and drainage; fire-protection requirements; HVAC; water heating; special access or construction conditions; and local jurisdiction requirements. A Site Assessment is recommended before the project scope and budget are confirmed.
What costs are excluded from an ADU model price?
ACSIOM model pricing is based on the standard home package and the scope specifically listed in the applicable proposal. Site-specific work may require additional cost.
Common examples include foundation and site preparation; utility trenching and connections; electrical meter, panel or service upgrades; water and sewer connections or upgrades; HVAC; water heaters; fire sprinkler systems when required; solar or battery systems; grading and retaining walls; landscape restoration; special transportation or crane access; site-specific structural or geotechnical work; and government, utility or third-party fees outside the stated proposal scope. The applicable proposal and contract define the final included and excluded items.
How do utility connections affect ADU cost?
Utility conditions can significantly affect the final project cost. Early planning typically reviews electrical service capacity; main panel and meter location; water and sewer connections; trenching distance; meter requirements; existing utility conditions; and potential upgrades or relocations.
A property with nearby utilities and adequate service capacity may require less work. Long trench runs, electrical upgrades, sewer modifications or utility relocation can add cost. Therefore, two homeowners selecting the same ADU model may have different total project costs.
Site & Feasibility
Can a two-bedroom ADU fit on my property?
Many Bay Area residential properties may be able to accommodate a two-bedroom ADU. ACSIOM ADU 749-26 is designed as a compact 749-square-foot, two-bedroom, two-bath home.
Suitability depends on available buildable area, side and rear setbacks, easements, the position of the main house and other structures, trees, utility locations, fire access, site slope, drainage and the overall property layout. A smaller backyard does not automatically mean that an ADU is not feasible. A Site Assessment can help identify an appropriate model and possible placement.
What happens during an ADU Site Assessment?
A Site Assessment evaluates whether a selected ACSIOM model may be appropriate for the property and identifies conditions that could affect design, permitting, construction or budget.
The assessment typically reviews the proposed ADU location, available buildable area, setbacks and easements, the main house and other structures, electrical service, water and sewer access, foundation and site conditions, construction access, trees and landscaping, fire access, drainage, material-delivery access and other visible site constraints.
After the assessment, ACSIOM can help identify suitable models, possible placement, items requiring further engineering or investigation and major cost factors to evaluate early. The Site Assessment is an early-stage feasibility review; final engineering, utility approvals, permit approval and concealed site conditions may still affect the project.
Products
How is an ACSIOM home different from a traditional custom-built home?
ACSIOM homes are designed as a system rather than one-off projects. Each model starts from a resolved architectural design, then takes shape through your choice of Architectural Collection, Interior Experience, and future-ready Smart Living pathways. That systemized approach is intended to bring more predictability to design and construction than a fully custom build, while still giving you meaningful architectural choice.
How do prefabricated, panelized and site-built ADUs differ?
The primary difference is where building components are produced and how much work is completed at the project site. Prefabricated ADUs have large portions manufactured off-site and transported to the property for installation and final connection. Panelized ADUs use walls, roof sections, floor systems or structural components prepared in advance and assembled on-site. Site-built ADUs complete most construction and fabrication directly on the property.
ACSIOM uses a standardized building-system approach with pre-engineered components and defined installation procedures to reduce unnecessary field fabrication, improve consistency and create a more repeatable construction process. The final method may vary by model, engineering requirements, site conditions and local approvals.
How much can I customize my home?
Every ACSIOM model can be shaped along three dimensions: the Architectural Collection (Modern, Contemporary, or Traditional, where offered for that model), the Interior Experience (Core, Select, or Signature), and the future-ready Smart Living pathways. This gives each home a distinct character without the open-ended complexity of a fully custom design.
What technology is included in an ACSIOM home?
ACSIOM Designs is bringing productized housing to market first. We are designing future-ready pathways into these homes: designated device locations, planned wiring routes, blank panels, and space for a central console. AIOS-CM is our operating-system vision for connecting those capabilities as devices and integrations are developed and validated. The first customer offering will be defined by its documented construction specification; connected features will be introduced as they become ready.
Your consultation will confirm what applies to the home you’re considering.
Can I use an ACSIOM home as a rental or investment property?
Many homeowners consider ADUs and small homes for long-term rental or multigenerational living. Whether that works for your property depends on local zoning and regulations, which are looked at as part of the site and regulatory review step. Our team can discuss how different models fit rental and investment scenarios during your consultation.
Smart Living & Privacy
How does ACSIOM handle privacy in an AI-ready home?
“AI-ready” means ACSIOM homes are being designed with future-ready pathways for connected features; it does not mean mandatory monitoring or surveillance. The first ACSIOM homes will be defined by their documented construction specification, and connected features will be introduced as they become ready.
If connected features are added to a home in the future, ACSIOM’s approach is to design them around homeowner control. Privacy settings, data handling and cloud dependencies will depend on the equipment, software platform and third-party services involved.
Will connected features be able to work without cloud services?
The first ACSIOM homes will be defined by their documented construction specification; connected features will be introduced as they become ready.
If connected features are added in the future, which functions can operate locally and which require internet or cloud services will depend on the devices, controllers and software selected at that time.
Will homeowners be able to turn off connected features?
The first ACSIOM homes will be defined by their documented construction specification; connected features will be introduced as they become ready.
If optional connected features are added in the future, ACSIOM’s approach is that homeowners should be able to adjust or turn them off, with the specific level of control depending on the equipment and software selected. Life-safety, fire-protection and code-required systems must remain operational in accordance with applicable regulations, approved plans and manufacturer requirements.
Process
Where does ACSIOM Designs currently serve?
ACSIOM Designs is based in San Jose, in California’s Silicon Valley. We actively serve San Jose, Santa Clara, Sunnyvale and Fremont. San Diego, Los Angeles, Sacramento, Roseville, Irvine and Rancho Cucamonga are pilot / project-review markets, where projects are reviewed case by case.
For other California locations, join the waitlist and we’ll keep you updated as new markets open.
Who handles permits and approvals?
ACSIOM Designs provides design and product configuration and coordinates engineering. Permitting responsibility, site work, construction, installation and final handover are assigned for each project to the responsible licensed parties, as defined in the project proposal and contract — so you know who handles what before any agreement is made.
Permit approval is decided by the local jurisdiction and cannot be guaranteed. Requirements vary significantly by city and county.
How long does it take to build an ACSIOM home?
Timelines depend on your site, local permitting requirements, and the model and configuration you choose. During your consultation and Site Assessment, we walk through the stages of your specific project — from permitting through construction, installation and handover — so you have a realistic picture before committing.
What happens after I join the waitlist?
You’ll receive updates on product availability and launch timing for the models you’re interested in, and you can book a consultation at any time. Joining the waitlist doesn’t commit you to anything — it simply keeps you first in line for updates.
Payments
How do pricing and deposits work?
ACSIOM ADU 749-26 starts at $349,000 based on the standard model scope. This is model/package pricing and is not the guaranteed total project cost. The applicable proposal and contract define the final inclusions, exclusions, payment terms and project price. Published pricing is planning guidance and not a formal quotation.
When a project moves forward, any deposit is handled through Stripe’s secure hosted checkout — ACSIOM Designs never stores your card details — and the applicable refund and cancellation policy is shared with you in writing before any payment.
