The U.S. Census Bureau’s 2024 American Community Survey counted more than 5 million multigenerational households nationwide, showing how common it is for several generations to share one home. In Los Angeles, that may mean remodeling for aging parents, adult children, grandchildren, or relatives who need more independence without moving far from family. A successful multigenerational remodel is not simply about adding bedrooms. It is about designing a home around privacy, accessibility, daily routines, and the ways each generation may use the property over time.
Direct answer: A multigenerational home is designed for two or more adult generations to live together while maintaining appropriate private and shared spaces. Effective multigenerational home remodeling in Los Angeles often combines private bedroom or living zones, accessible bathrooms, flexible common areas, additional storage, and, where appropriate, an addition, garage conversion, or ADU.
Start With the Needs of Every Generation Before Changing the Floor Plan
Before moving walls or adding square footage, determine how everyone will actually live in the home. A multigenerational floor plan should respond to different schedules, privacy expectations, mobility needs, and household responsibilities.
A useful pre-remodel checklist is:
- Identify everyone who will regularly live in the home.
- Decide which bathrooms and living areas should be private.
- Map work, school, sleep, cooking, and caregiving schedules.
- Identify accessibility needs that exist today or may develop later.
- Determine whether the existing footprint provides enough functional space.
Identify Who Needs Private Space and Who Will Share Space
Start with sleeping arrangements, bathrooms, work-from-home needs, children’s study or play areas, quiet spaces, and common gathering rooms.
A private zone does not necessarily require a completely separate dwelling. For some households, a bedroom suite with its own bathroom and storage provides enough independence. Others may benefit from a small sitting room or a more distinct section of the house.
Plan Around Different Daily Routines
Two families can share the same square footage very differently. Early risers may use the kitchen while another generation sleeps. Children may need homework areas while adults work remotely. Older family members may prefer quieter spaces away from televisions and entertaining areas.
Mapping these routines before developing the floor plan can reveal where additional separation, bathroom capacity, storage, or circulation improvements matter most.
Design for Today Without Ignoring the Next 10 Years
Good multigenerational home design is adaptable. An adult child may eventually move out. An aging parent may later need easier bathroom access. A nursery might become an office or guest room.
Flexible rooms, accessible circulation, and thoughtful connections between private and shared areas can help a remodel remain useful as the household changes.
Create Private Living Zones Without Making the Home Feel Divided
Privacy is one of the most important considerations in a multigenerational home remodel. The goal is usually not to isolate family members, but to create enough separation that everyone can maintain a sense of independence.
Ways to add privacy to a multigenerational home include:
- Private bedroom and bathroom suites
- Separate floors or wings
- Hallways or transition spaces between living zones
- Independent entrances where appropriate
- Better separation between entertainment and sleeping areas
- Sound-conscious wall, door, and room placement
Use Bedroom Suites as Private Retreats
An in-law or extended-family suite may combine a bedroom, bathroom, closet, and small sitting area. Locating the suite away from high-traffic spaces can also reduce unnecessary circulation through someone else’s private area.
For homes that need additional conditioned space, Nextgen’s room addition services provide one potential remodeling path for creating a dedicated suite or living zone.
Separate Living Areas by Floor, Wing, or Transition Zone
Existing architecture can often help establish privacy. Parents might occupy a main-level section while younger family members use bedrooms upstairs. In wider homes, front and rear zones may work better.
Pocket doors, vestibules, hallways, built-in storage, or shared transitional rooms can establish boundaries without making the house feel like two unrelated spaces.
Consider Independent Entrances Where the Property and Design Allow
A separate entrance may provide additional independence for an adult child, parent, or long-term relative. Some families still prefer an internal connection so everyone can move between spaces without going outdoors.
Whether an independent entrance works depends on the home’s configuration, proposed use, zoning, and permitting requirements.
Control Noise Between Generations
Avoid placing a television room directly against a quiet bedroom when possible. Strategic room placement, wall insulation, solid-core doors, and transition spaces can help reduce sound transfer.
Noise planning becomes especially important when household members have different sleep, school, work, or entertainment schedules.
Remodel Kitchens and Bathrooms for Shared Living Without Daily Bottlenecks
Kitchens and bathrooms frequently become pressure points when more people share a home. Adding capacity does not always mean duplicating entire rooms. Sometimes better layout and circulation solve the problem.
Give a Shared Kitchen More Than One Work Zone
A multigenerational kitchen may benefit from larger preparation surfaces, multiple countertop work zones, easier-to-reach storage, additional pantry capacity, and appliance placement that allows two people to cook without continually crossing paths.
Homeowners substantially reworking these spaces can explore Nextgen’s kitchen remodeling services as part of broader whole-home planning.
Decide Whether a Secondary Food-Prep Area Makes Sense
A beverage station, compact food-preparation area, or kitchenette can give relatives more independence without automatically creating a second full kitchen.
Whether a secondary cooking area is appropriate should be reviewed during design because its configuration can affect how the space is classified and what approvals may apply.
Add Bathroom Capacity Where It Reduces the Most Conflict
An additional ensuite bathroom, powder room, double vanity, or separated sink area may noticeably improve morning routines.
For older relatives, bathroom planning can also address accessibility at the same time. Nextgen’s bathroom remodeling services can be considered within a larger multigenerational renovation.
Make the Home Safer and More Comfortable for Aging Parents
A multigenerational remodel is an opportunity to make the home easier to navigate as family members age. The National Institute on Aging’s home-safety guidance recommends measures such as improved lighting, reducing fall hazards, and installing appropriate bathroom support features.
Prioritize a Bedroom and Full Bathroom on the Main Level
When the existing home allows it, placing an older adult’s primary bedroom and full bathroom on the main level can reduce dependence on stairs.
Even when stairs are manageable today, designing around fewer level changes may make the home more adaptable later.
Design Bathrooms for Easier Movement
Depending on the household and available space, useful features may include:
- Curbless or low-threshold showers
- Comfortable circulation areas
- Blocking for possible future grab bars
- Slip-resistant flooring
- Improved lighting
- Convenient fixture placement
Accessibility needs vary, so design decisions should be based on the people who will actually use the room.
Improve Everyday Circulation Throughout the Home
Look beyond the bathroom. Wider, unobstructed pathways, better lighting, easier-to-operate door hardware, convenient storage, and fewer abrupt level changes can make everyday movement more comfortable.
Choose Features That Work for Every Generation
Universal-design ideas do not need to make a house look institutional. Lever handles, bright task lighting, comfortable circulation, and easy-entry showers may also benefit children, guests, injured family members, and adults carrying groceries or laundry.
Decide Whether an Addition, Garage Conversion, or ADU Better Fits the Family
There is no single best construction strategy for multigenerational living. The right approach depends on the existing house, lot, desired level of independence, available space, utilities, parking, zoning, and budget.
| Option | Best Suited For | Level of Separation |
| Interior reconfiguration | Homes with enough existing square footage | Low to moderate |
| Room addition | Families needing more space within the main residence | Moderate |
| Garage conversion | Properties where existing garage space can be repurposed | Moderate to high |
| ADU | Relatives seeking greater day-to-day independence | High |
Reconfigure the Existing Interior When the House Has Enough Space
Underused bedrooms, formal dining rooms, oversized living spaces, and inefficient hallways may provide opportunities to improve privacy without expanding the building footprint.
Reviewing examples of Nextgen’s full-home renovation work can help homeowners think about how several spaces may be coordinated as one remodeling project.
Consider a Home Addition When More Conditioned Space Is Needed
An addition may create a new bedroom suite, family room, bathroom, or dedicated living zone while keeping the household within the primary residence.
Site conditions, structural requirements, zoning, and the relationship between the new and existing portions of the home should be evaluated before assuming an addition is feasible.
Evaluate a Garage Conversion for More Separation
A garage’s location can make it attractive for an in-law suite or private living area, but homeowners should consider parking, utilities, access, ventilation, natural light, existing construction, and the intended legal use of the converted space.
Nextgen offers ADU and garage conversion services for homeowners considering this type of property transformation.
Consider an ADU When Greater Independence Is the Goal
California’s Department of Housing and Community Development ADU guidance describes ADUs as independent residential units, while LADBS notes that Los Angeles ADUs can include attached units, detached structures, and converted spaces.
An ADU may therefore work well for an aging parent or adult child who wants a more independent household while remaining on the same property.
Preserve Family Connection Through Thoughtful Shared Spaces
Privacy should not eliminate the reason many families choose multigenerational living in the first place. Shared spaces should make it easy to spend time together without requiring everyone to occupy the same room throughout the day.
Make the Main Living Area Comfortable for Different Ages
Provide different seating choices, clear walking paths, layered lighting, and convenient connections among the kitchen, dining, and living spaces.
Create Smaller Shared Spaces in Addition to One Large Great Room
Useful secondary gathering spaces can include a breakfast nook, den, reading area, patio, homework station, or hobby room. These smaller spaces allow family members to interact without crowding one central great room.
Connect Indoor and Outdoor Living
Los Angeles’s climate makes patios and outdoor gathering areas especially useful. Consider comfortable transitions, shade, seating, and circulation so family members can move naturally between indoor and outdoor spaces.
Address Storage, Parking, Laundry, and Other Details That Become Bigger With More People
Small logistical problems can become daily frustrations when the number of people in a home increases.
Increase Personal and Shared Storage
Plan bedroom closets, linen storage, pantry capacity, entry storage, and space for items such as strollers, sports equipment, mobility devices, or seasonal belongings when relevant.
Reduce Laundry Conflicts
Consider where the laundry room sits relative to bedrooms, how much storage it provides, and whether everyone must travel through another household member’s private area to reach it.
Think Through Parking and Household Entrances
Additional adults often mean additional vehicles. Review driveway circulation, garage use, available off-street parking, neighborhood conditions, and how a garage conversion or addition could change existing parking arrangements.
Check Los Angeles Requirements Before Finalizing the Design
Multigenerational remodeling can involve structural changes, additions, plumbing, electrical work, garage conversions, or new dwelling units. Approval requirements depend on the actual scope and property.
Confirm the Property’s Existing Conditions and Zoning
For properties within the City of Los Angeles, City Planning’s ZIMAS zoning search can provide information about a property’s zoning, planning history, overlays, and related records.
Start by confirming the existing permitted configuration, structures, zoning conditions, and intended use of remodeled areas.
Determine Which Parts of the Remodel Require Approval
Structural alterations, additions, conversions, plumbing, electrical work, and ADUs may involve different reviews and permits. The Los Angeles Department of Building and Safety ADU resources are particularly relevant when a project creates a separate dwelling unit.
Do not assume that a design that works on one Los Angeles property will receive identical treatment on another.
Account for Property-Specific Regulations Early
Planning overlays and specially regulated locations can add another layer of review. Los Angeles City Planning records include coastal projects involving an existing-home remodel, addition, and ADU that required separate coastal review, illustrating why property-specific research should happen before final design.
Nearby cities also have their own processes. For example, the City of Pasadena Permit Center separately handles remodeling, additions, conversions, and ADU submissions for Pasadena properties.
Plan a Los Angeles Multigenerational Remodel Around How Your Family Actually Lives
The most successful multigenerational remodeling plan begins with people rather than square footage. Define how much independence each generation wants, where accessibility matters, what everyone will share, and how those needs may change.
Define the Family’s Privacy, Accessibility, and Shared-Space Priorities
Before selecting a design direction, establish:
- Who will live in the home
- Which spaces should remain private
- Which rooms everyone will share
- Whether accessibility needs may change
- Whether the existing footprint offers enough space
Evaluate the Existing Home Before Choosing a Remodeling Strategy
An interior reconfiguration may be enough for one family, while another property may be better suited to a bedroom-suite addition, garage conversion, or ADU.

Frequently Asked Questions About Multigenerational Home Remodeling
What is a multigenerational home?
A multigenerational home accommodates more than one adult generation within the same household. Remodeling may create private bedroom suites, separate living zones, accessible areas, additional bathrooms, or independent living spaces while preserving common areas for the family.
How can I create privacy in a multigenerational house?
Start with bedroom placement, private bathrooms, separate floors or wings, transition spaces, noise control, and clearly defined circulation paths. Depending on the home, a separate entrance or more independent suite may also make sense.
Is an ADU better than an in-law suite?
Neither is automatically better. An in-law suite usually keeps relatives more closely connected to the primary residence. An ADU provides greater independence because it functions as a separate dwelling. Property conditions, family preferences, zoning, permitting, utilities, and budget should guide the decision.
Can I convert my garage into living space for my parents?
Potentially. A garage conversion should be evaluated for its existing construction, intended use, parking implications, utilities, access, building requirements, and local regulations. If the space is intended to become an independent dwelling, ADU requirements may apply.
What should I include for aging parents?
Consider convenient sleeping and bathing spaces, reduced dependence on stairs, good lighting, easier circulation, appropriate shower access, slip-resistant surfaces, and the ability to install support features if needs change.
Do multigenerational remodels require permits in Los Angeles?
Permit and planning requirements depend on the work being performed and the property. Structural work, additions, utility changes, conversions, and ADUs may require approvals. Property zoning and existing permit history should be researched before plans are finalized.
A comfortable multigenerational home gives family members opportunities to be together without requiring them to sacrifice independence. In Los Angeles, begin by understanding each generation’s routines, then evaluate privacy, accessibility, kitchens and bathrooms, storage, parking, and the appropriate remodeling strategy. Before committing to a floor plan, confirm the property’s existing conditions and local requirements and have a qualified remodeling team evaluate which options are realistic for the home.
