Turn unused space into income-generating ADUs & beautiful additions
Most Massachusetts Property Owners Are Sitting on a Missed Income Opportunity and Don’t Even Know It
Because of a new Massachusetts ADU law, your property may now allow a legal second living unit — rental income, added value, and long-term flexibility — without rezoning.
But here’s the problem:
Most homeowners and property owners still think the old rules apply.
And while they wait… they miss out.

What Changed in Massachusetts (2024 ADU Law)
Massachusetts passed a new law that quietly changed the game for homeowners.
In many situations:
ADUs are now allowed by right
Special permits may no longer be required
Towns can’t outright ban ADUs
Homeowners gained more flexibility than ever before
But here’s the part no one tells you:
The law made ADUs easier, not automatic.
Design, setbacks, utilities, size limits, and local interpretation still matter.
Get one thing wrong, and your project stalls.
Why Most ADU Projects Fail Before They Start
We see the same mistakes over and over:
Designing before checking zoning reality
Hiring builders who don’t understand the law
Paying architects for plans that won’t get approved
Assuming “by right” means “no rules”
Underestimating how towns interpret the law
A denied permit isn’t just frustrating and it’s expensive.
Months lost.
Money wasted.
Momentum gone.
Who This Is For
This page is for homeowners and investors who:

Rushing into design without clarity
Why PS3 Remodel, Design & Build Is Different
Most contractors build first… and figure things out later.
We don’t.
PS3 is a design-build firm that understands:
The Massachusetts ADU law
Local zoning interpretation
Permit realities
Structural and design constraints
Construction execution
Everything is handled under one roof:
Feasibility review
Code-aligned design
Permit coordination
Construction
One team. One plan. One accountable outcome.
ROI: How ADUs & Additions
Create Real Income
Monthly Rental Income - A legal ADU can generate predictable monthly cash flow and help offset mortgage costs.
Increased Property Value - Homes with legal, code-compliant ADUs often appraise higher due to income potential and flexibility.
Built-In Flexibility - Even if you don’t rent immediately, ADUs provide:
Housing for aging parents
Space for adult children
Future rental options
Flexibility is a form of financial leverage.
Return on Investment.
Not just resale value — but monthly income, flexibility, and long-term leverage.
Why ROI Starts Before Construction
Poor early decisions can:
Limit rental potential
Reduce appraised value
Increase costs
Delay income
Smart feasibility planning:
Maximizes usable square footage
Reduces approval risk
Aligns design with income goals
Protects your investment
Here’s the truth most contractors won’t tell you:
ROI is decided at the planning stage — not after the build

Meet the Builder Behind
the Work
Paulo Santos has been working in design and construction since the age of 16.
That’s over 30 years of hands-on, real-world experience.
He didn’t learn construction from shortcuts or theory.
He learned it:
On job sites
Through real projects
By solving real problems
By being accountable for the outcome
Experience like this doesn’t show up in proposals.
It shows up when problems are avoided entirely.
ADUs and additions are not beginner projects.
They demand experience — not guesswork.
The PS3 ROI-First Approach
At PS3, we don’t just ask:
“Can this be built?”
We ask:
“Does this make financial sense?”
Every feasibility consultation considers:
Income potential
Approval risk
Long-term usability
Resale impact
Cost vs return alignment
Because building something that technically works — but financially underperforms — is still a loss.

FAQ
Common questions about ADUs and additions
Don’t see your question here? Ask it in the quote form and our team will respond within one business day.
How long does an ADU or home addition project usually take?
Timelines vary by scope and city, but most ADUs take 2–4 months for design and permits, followed by 4–6 months of construction. Larger additions can run 6–9 months. After your feasibility study, we’ll provide a personalized schedule with clear milestones.
Do you handle permits and work with the city?
Yes. Our team prepares the full permit set, submits it to the city, coordinates plan check comments, and attends any required inspections. You stay informed, but we handle the back-and-forth with building departments.
Can you work with my budget?
We start with your target budget and design toward it, presenting options at different finish levels. If an ADU or addition is not realistic within your budget, we’ll be upfront before you commit to a build contract.
Is financing available for ADU or addition projects?
Many clients use home equity loans or specialized renovation financing. While we’re not a lender, we can connect you with partners who understand ADU and addition projects and can walk you through options.
Will construction disrupt our daily life?
We plan access, staging, and work hours to minimize disruption. For detached ADUs, impact is usually limited to access paths and utility tie-ins. For additions, we phase work to keep as much of your home livable as possible and maintain clean, safe jobsites.
