Most homeowners looking for a deck builder in Massachusetts have the same worry: "Will this turn into a paperwork mess?" If your website answers that clearly, you look like the careful builder in the stack of quotes. If it says nothing, they assume the worst or ask a cheaper competitor who says "no permit needed."
This post covers what to say about deck permits on your site, which facts to check, and how to set the page up. It's general information, not legal advice. Have your own page checked against your town's current rules.
Why a permit page helps you win jobs
Permit questions come up on almost every deck call. Answering them once, in writing, saves phone time. It also screens out the homeowner who wants the job done "off the books," which is not a customer you want.
A good permit page does three things:
- Shows you know the local process, which builds trust before the first visit.
- Sets expectations on timing, so a homeowner doesn't blame you for the building department's queue.
- Gives your estimate a reason for the permit and inspection line items, so they don't look like padding.
What to explain, and what to verify first
Start with the state basics, then add what your town does differently. Here is a table of the questions homeowners ask, with the plain-English answer and what to confirm locally.
| Homeowner question | Plain answer (as of 2026) | Confirm with your town |
|---|---|---|
| Which code applies? | The 10th Edition of 780 CMR took effect October 11, 2024, and became the only building code in effect after the concurrency period ended June 30, 2025. It is based on modified 2021 International Codes. | Whether your town has any local amendments or handouts |
| Do I need a permit? | There is one narrow exemption: not attached to a dwelling, no larger than 200 square feet, no more than 30 inches above grade, and not serving a required exit door. Any deck attached to the house needs a permit, no matter the size. | Exact thresholds, since sources word the 200 square foot limit slightly differently |
| What about a patio? | Mass.gov's home improvement table lists decks as needing a CSL, an HIC registration and a building permit, while patios need none of the three. | Zoning and drainage rules |
| How deep are footings? | Massachusetts lists a 48-inch frost depth statewide in Table R301.2(1) of the residential code. | What the inspector expects on your soil and design |
| Is a call to Dig Safe needed? | State law requires calling 811 at least three days before digging, and building a deck is a listed example. | Who places the request (usually the builder) |
Don't publish permit fees or turnaround times as fixed numbers. They vary because local building departments and zoning bylaws can add their own rules. Link to the town's fee schedule or say "we'll give you the exact fee in your estimate."
Explain who pulls the permit: CSL, HIC and the homeowner exemption
This is where Massachusetts confuses people, so spell it out in short paragraphs.
Two credentials, two jobs. Mass.gov says larger projects, such as building a deck or an addition, require a CSL. Separately, contractors who perform work on existing, owner-occupied properties with one to four units must be registered as Home Improvement Contractors. Say which ones you hold, and tell homeowners where to verify them on mass.gov.
Put your HIC number where the state expects it. Mass.gov states that building permits, contracts and advertising for residential contracting must contain the contractor's active registration number. That includes your website. Put it in the footer and on the contact page, and check that it appears on every ad you run.
Contracts over $1,000. Under the Home Improvement Contractor law, contracts over $1,000 must be in writing. A line on your page about what the written contract and estimate include is a trust builder.
The homeowner exemption. Some homeowners will ask if they can pull the permit themselves. Town forms explain that the homeowner must supervise anyone they hire to do the permitted work, and that an owner who pulls a permit this way will not have access to the arbitration program or guaranty fund under M.G.L. c. 142A. You don't need to argue against it. State it plainly and let them decide.
Walk homeowners through the timeline
A numbered process on the page reduces "what's next?" calls. Adapt this to how your crew and town actually work:
- Site visit and design. You measure, note height above grade, attachment to the house and any exit door, and discuss materials.
- Drawings and application. The application typically includes a plan showing the deck's size, location on the lot, footing layout, framing details and how it connects to the house.
- Zoning check. Building-code review looks at construction standards, while zoning review looks at how the deck fits the property's rules. Setbacks are the usual trouble. Properties near wetlands can bring in the conservation commission.
- Dig Safe mark-out. Utilities get marked before any footing is dug. Note that the 72-hour notice excludes weekends and legal holidays, so this can add to your schedule.
- Footing inspection. Many departments require a footing inspection before concrete is poured.
- Framing inspection. This happens after the structural frame is up but before decking goes down.
- Final inspection. This comes after all work, including railings and stairs, is complete.
Inspection stages differ by town, so label this as "typical" and name the ones your local department uses. If you work in several towns, a short section per town with a link to its building department is more honest than one blanket answer.
Why skipping the permit is a bad idea (say it calmly)
Homeowners get tempted by the "no permit" quote. Explain the downside without scaring them. According to one Massachusetts builder guide, building without a permit can bring a stop-work order, an after-the-fact permit at a doubled or tripled fee, and an exposure inspection of concealed framing. Another source notes that the building department can impose a double fee before issuing a retroactive permit. Penalties vary by town, so keep your wording general: "Unpermitted work can mean extra fees, rework and trouble when you sell."
Where to put this on your site
Don't bury it in a blog post nobody finds. Use this layout:
- A dedicated "Permits and Inspections" page, linked from your deck services page and the main menu.
- A short FAQ block on each deck service page (pressure-treated, composite, railings) with a link to the full page.
- Your credentials in the footer, including CSL and HIC numbers.
- A "what's included in your quote" line listing permit filing, drawings and inspection coordination.
- A clear call to action at the bottom: request a site visit.
For the rest of the page structure, see our guide to deck builder website pages and features. If you're choosing who builds the site, hiring a web designer for your trade business covers the questions to ask. Once the page brings in inquiries, an estimate follow-up sequence keeps those quotes from going cold.
Mistakes to avoid
- Quoting the old code. Any page that references the 9th Edition is out of date.
- Giving legal advice. Explain the process and link to official sources. Don't tell people what the law "definitely" requires on their lot.
- Promising dates. Say "timing depends on your town's review," not "permit in a week."
- Hiding the cost. If the permit and drawings are in your price, say so. If they're separate, say that too.
- Forgetting to update. Put a "last reviewed" date on the page and set a calendar reminder to recheck it each year before deck season.
