Multigenerational & Universal Design Drafting Services
Households are combining generations under one roof more than ever, whether that means an aging parent moving in, adult children staying longer, or a family planning ahead for the years they'll spend in this same house. We draft floor plans built around that reality: accessible, private where it needs to be, connected where it should be, and ready for permit submission.
What This Service Is and Who It's For
Multigenerational and universal design drafting covers two related goals: laying out a home so multiple generations of one family can live together comfortably, and building in accessibility features so the home continues to work for its residents as mobility needs change over time. Sometimes these overlap in the same project. Sometimes a client only needs one or the other.
This service is a fit if you are:
- Planning a new house that needs to work for a parent, in-law, or adult child living with you long-term
- Adding a private suite, wing, or secondary living space onto an existing home
- Designing or remodeling with aging in place in mind, for yourself or a family member
- Building for a household member with a mobility limitation, current or anticipated
- A builder or contractor who needs accessibility-conscious plans for a client project
We serve homeowners, builders, and contractors nationwide, remotely, with a focus in Texas, Florida, New York, and California. Every project is drafted around your household's actual needs rather than a generic template, because the reasons a family needs this kind of layout vary widely from one household to the next.
What's Included
Depending on the scope of your project, a multigenerational or universal design package can include:
Accessibility-Conscious Layout Features
- Zero-step or low-threshold entries
- Wider doorways and hallway clearances
- Curbless or roll-in shower layouts
- Single-level living arrangements where feasible
- Wall blocking notation for future grab bar installation
- Clear turning radius planning in kitchens and bathrooms
Dual Living Space Planning
- Private or semi-private secondary suites
- Separate or discreet entrances
- Kitchenette or secondary kitchen layouts where allowed
- Sound and privacy separation between living areas
- Shared vs. separate utility layout options for discussion with your jurisdiction
Every project includes full construction drawing sets: floor plans, elevations, and the supporting documentation needed to move your project toward permit. If your project also needs visual walkthroughs to help family members agree on a layout before construction, ask about pairing this service with 3D Renderings & Walkthroughs.
Our Process for Multigenerational and Universal Design Projects
- Household needs conversation. We start by understanding who will live in the home, their current and anticipated mobility needs, and how much privacy or separation each generation wants.
- Site and structure review. For additions and remodels, we assess your existing home's structure and site conditions to determine what's feasible. For new construction, we work from your lot and program requirements.
- Layout drafting. We draft the floor plan around accessibility clearances and living-space separation, balancing togetherness with privacy based on what you told us in step one.
- Review and revisions. You review the layout with your household. A set number of revisions is included and confirmed at quote, so gather feedback from everyone before sending it back to us.
- Permit-ready delivery. Once the layout is approved, we finalize the full drawing set for submission to your local building department.
Turnaround
Timelines vary by project scope and jurisdiction. A single accessible suite addition moves differently than a full multigenerational new-construction home with two living zones. We'll give you a specific timeline estimate once we understand your project scope and location during your quote.

Frequently Asked Questions
What is universal design and how is it different from ADA compliance?
Universal design is a set of layout and feature principles that make a home usable by people of all ages and ability levels, from a toddler to a grandparent using a walker. ADA compliance is a specific legal code that applies mainly to commercial and public buildings. Most single-family homes are not legally required to meet ADA standards, but we draft using universal design and aging-in-place principles so the home works well for the people who will actually live in it. Any code requirement that does apply to your project is confirmed against your local jurisdiction during drafting.
Can you add an accessible suite to our existing home instead of a new build?
Yes. Many of our multigenerational projects are additions or remodels to an existing house rather than new construction. We evaluate your existing structure, structural constraints, and site conditions, then draft an addition or reconfigured layout that meets your accessibility and privacy goals. If your project is closer to a straightforward room addition without the accessibility component, our Home Additions & Remodel Drafting service may be the better starting point.
Do you design separate entrances and utility metering for a second living space?
We can draft a separate or semi-private entrance, and we will lay out the plan to support separate utility metering if that is something you want to pursue. Whether separate metering is required, optional, or restricted depends on your local jurisdiction and utility provider, so that detail is confirmed with your building department as part of the drafting process rather than assumed in advance.
Is a multigenerational suite the same as an ADU?
They can overlap, but they are not always the same thing. An ADU is typically a distinct dwelling unit, often detached or with its own address, governed by its own set of zoning rules. A multigenerational suite is often attached to and integrated with the primary home, sharing some systems or spaces. If your goal is a fully independent unit, take a look at our ADU Plans & Design service. If your goal is connected but separate living space within one home, this service is the right fit.
What accessibility features can be included in the drawings?
Common features we draft include zero-step entries, wider doorways and hallways, curbless showers, blocking in walls for future grab bars, lever-style hardware notations, single-level living arrangements, and turning radius clearances in bathrooms and kitchens. The specific mix of features included in your set is confirmed with you at the quote stage based on your household's needs and budget.
How many people can review or request changes to the plan?
We are happy to gather input from everyone who will live in the home, including extended family members joining the household. A set number of revisions is included in your project and confirmed at quote, so we recommend consolidating feedback from all household decision-makers before each review round to make the most of them.
