Falmouth Building Department 2026: Permits, Inspections & Services

Falmouth Building Department Contact Information

The department issues and reviews building permits, performs construction inspections, handles building-code enforcement and works with zoning requirements. Separate inspectors handle electrical, plumbing and gas work.

For current staff assignments, use the Town’s official inspector information page.

How to Apply for a Falmouth Building Permit Online

Falmouth uses PermitEyes. You do not need to visit several unrelated websites to begin a standard building application. Start from the Town’s official permitting page and follow the application through the same system.

1. Open the official Falmouth permit page.
   Go to Falmouth Online Permitting. This page links directly to the authorized PermitEyes registration, login and public-record tools.
2. Create a PermitEyes account if you are a new applicant.
   Use the Falmouth PermitEyes registration page. Enter your contact information and, when applicable, contractor or professional-license details.
3. Choose “New Application.”
   After signing in, select the building module and the permit type that fits the proposed work. Do not choose a permit only because its name looks close; the project scope determines the correct application.
4. Select the property from the Town address list.
   Falmouth connects applications to its address database. Use the available dropdown rather than manually creating a different version of the address.
5. Complete every required field.
   Fields marked with a red star are mandatory. A partially completed application may not move forward.
6. Upload plans and supporting approvals.
   Depending on the project, this can include a site plan, construction drawings, contractor credentials, workers’ compensation information, Conservation approval, Historical Commission approval, zoning decisions or flood-related documents.
7. Submit and monitor the Status Panel.
   From your PermitEyes home page, use the eye icon to open the Status Panel. The paperclip is used for documents, while the chat function is used for communication with department staff.
8. Pay after the Town calculates the fee.
   PermitEyes provides a PAY NOW function once the applicable amount has been entered. Save your receipt and continue watching the application for approval or correction requests.

How to Search Falmouth Permits Without an Account

If you are checking a permit on your own property, researching a house before purchase, confirming whether work was finalized, or looking for an old application, Falmouth provides a public PermitEyes search.

1. Open the Falmouth Public PermitEyes portal.
2. Select the BLDG section for building records.
3. Search using the permit or application number when you have it. That is normally the most precise method.
4. If you do not have a permit number, use available columns such as street number, street name, parcel number, owner, applicant or description.
5. Open the record and check the application date, issue date, permit number, status, inspections and available attachments.
6. For property due diligence, check related electrical, plumbing, gas or other permits instead of assuming one building record represents the entire project.

What to Prepare Before Filing

The exact documents depend on the project, but preparing the property and zoning information before opening the application can prevent avoidable review delays.

• Correct property address and assessor parcel information.
• Owner and applicant contact details.
• Detailed description of the proposed work.
• Estimated construction cost where requested.
• Construction plans drawn to the required scale and detail.
• Contractor and Massachusetts license information where applicable.
• Workers’ compensation documentation or applicable homeowner exemption paperwork.
• Site or certified plot plan when required.
• Flood-zone information for affected properties.
• Conservation approval where work affects regulated wetland areas.
• Historical Commission approval for applicable properties and exterior work.
• Zoning Board decision when a special permit or variance is required.
• Health or septic documentation when a property is not served by the applicable sewer system.

Falmouth Site Plan Requirements

The Town’s site-plan guidance says permit plans may need to show assessor map/section/parcel/lot information, flood zone, zoning district, overlay districts, existing and proposed structures, exact setbacks, septic location, street address, wind information and lot coverage. Plans requiring certification should carry the appropriate surveyor or engineer information.

Review the official Falmouth site-plan requirements before ordering a survey so the professional preparing it knows what the Building Department expects.

How Long Does Permit Review Take?

Falmouth’s published building FAQ says a typical permit may take about 10 to 30 days to receive all necessary departmental review and final sign-off. The actual time depends on the project, completeness of the submission and additional approvals.

The Town identifies some work—such as reshingling, residing, reroofing, windows and doors—as express-type work that may be processed more quickly. That does not mean every project in those categories is automatically approved immediately.

Falmouth Building Permit Fees

The Town’s Building Department fee page currently displays an approved fee schedule effective January 1, 2025. Because this guide is for 2026 and municipalities can revise charges, use the figures below for planning and verify the live amount on the official Falmouth fee page before paying.

Electrical, Plumbing and Mechanical Fees

Falmouth uses separate trade fees. Examples on the published schedule include $100 for residential new-construction electrical permits, $75 for residential alterations/remodels/additions, $100 for residential generators and $150 for swimming-pool electrical permits. Plumbing and gas charges are based partly on the number of fixtures or appliances. Mechanical/sheet-metal work is also separately listed.

Do not add these amounts together blindly. Your actual invoice depends on the permit combination and project details shown in PermitEyes.

How Falmouth Building Inspections Work

Inspection timing matters in Falmouth. Covering work before an inspector sees the required stage can cause delays, additional work or a reinspection fee.

Building Inspections

Call 508-495-7470 to arrange a building inspection. The Town’s dedicated inspection page says building inspections are taken one day in advance. Have these three items ready:

• Job-site address
• Permit number
• Type of inspection requested

Falmouth requires house numbers to be posted at the site. Stamped plans and the building card must remain available at the job site.

Typical New Construction / Addition Inspection Sequence

The Town also publishes project-specific sequences: decks generally require sonotube, framing and final inspections; sheds and above-ground pools may require a final inspection; in-ground pools include electrical, steel/rebar or collar and final inspection stages.

Electrical and Plumbing Calls Are Different

Electrical: the licensed electrician performing the work should call 508-495-7473 between 7:00 and 8:30 a.m.. Rough and final inspections are required where applicable.

Plumbing/gas: the licensed plumber or gas fitter should call 508-495-7474 between 7:00 and 8:30 a.m.. The Building Department also publishes an assistant plumbing inspector number, 508-495-7476, for Tuesday and Thursday morning availability.

For the latest scheduling instructions, check the Town’s Building Inspections page before calling.

Local Checks That Can Delay a Falmouth Permit

On Cape Cod, a building permit can involve more than structural drawings. Falmouth properties may have zoning, wetland, flood, historic-district or lot-status issues that need to be resolved before the Building Department can issue the permit.

Zoning and Setbacks

Falmouth’s published FAQ says common residential setback requirements in many areas are approximately 25 feet from the front property line and 10 feet from side and rear property lines. These are not safe universal numbers for every parcel. District rules, pre-existing nonconformities, corner lots, accessory structures and special permits can change the result.

If your plan is close to a property line, confirm the zoning before paying for final construction drawings. Use the Town’s zoning resources and obtain a survey when accurate property-line placement matters.

Sheds and Small Accessory Structures

Falmouth’s shed guidance says residential sheds larger than 200 square feet require a building permit. A residential shed of 100 square feet or less is generally subject to a minimum 3-foot side and rear setback, while sheds greater than 100 square feet are generally subject to a 10-foot side and rear setback under the cited local rules.

The same guidance says sheds cannot simply be placed in a front yard without the required zoning approval, and shed area counts toward lot coverage. Even a shed small enough to avoid a building permit may still need historic or conservation review.

See the Town’s official fence and shed guidance.

Swimming Pools

Falmouth states that an in-ground or above-ground pool that is 24 inches deep or greater requires a building permit. Pool projects may also involve electrical inspections, barriers and other safety requirements.

Wetlands and Conservation

If your project is close to wetlands or another regulated resource area, do not rely only on an online map. The Town’s Conservation Department provides guidance for work within 100 feet of resource areas.

Contact Conservation at 508-495-7445 or review the Falmouth Conservation Department before finalizing site work.

Historic District Properties

Falmouth has seven local historic districts. Exterior work such as new construction, additions, renovations, sheds, fences, stone walls, signage and certain material or color changes can require Historical Commission review before a building or sign permit is issued.

Historic applications are submitted through the Planning/Historic module in PermitEyes. Depending on the proposed work, the result may be an administrative approval or a Certificate of Appropriateness requiring a public hearing.

Check the Falmouth Historical Commission instructions early. Waiting until the building application is otherwise complete can add unnecessary time.

Flood-Zone Properties

Falmouth’s site-plan guidance requires flood-zone information when applicable. For new construction and major renovations in flood areas, an elevation certificate or professional flood-related plan may be required.

This matters especially in coastal areas because the Massachusetts Tenth Edition Building Code includes updated flood-protection provisions. Use certified survey or engineering information rather than estimating elevations from a general map.

Is a Vacant Lot Buildable?

An assessor parcel number or tax assessment does not guarantee that a lot is legally buildable. Falmouth’s vacant-lot guidance says the Town does not make a final buildability determination until a complete building permit application and supporting documentation have been submitted.

If you are researching vacant land, review the Town’s Buildable Lot Packet before assuming that an old lot, undersized parcel or prior letter establishes a right to build.

Which Building Code Applies in Falmouth in 2026?

For 2026 applications, the current statewide building code is the Massachusetts State Building Code, 780 CMR, Tenth Edition. The Tenth Edition first took effect October 11, 2024. The transition period allowing use of the Ninth Edition ended June 30, 2025, making the Tenth Edition the applicable statewide edition for new 2026 applications.

The code is based on modified 2021 International Codes and includes Massachusetts-specific amendments. Depending on the project, separate electrical, plumbing, fire, accessibility, energy and local zoning requirements can also apply.

Use the state’s official 780 CMR resource when you need the governing code text or current amendments.

Common Falmouth Permit Problems

Make Sure You Are Using the Correct Cape Cod Department

Falmouth permits apply to property within the Town of Falmouth. A Cape Cod mailing address or nearby location does not mean Falmouth has jurisdiction. If the property is elsewhere, use that municipality’s own permit office. Our related guides include the Bourne Building Department, Barnstable Building Department, and Brewster Building Department.

Falmouth Building Department FAQs

Before You Start Work

The fastest permit process is usually the one prepared correctly before submission. Confirm the property’s zoning and site constraints, collect the required plans and professional documents, submit through PermitEyes, monitor review comments and wait for the actual permit to be issued.

Once work starts, keep the approved plans and permit information at the site and schedule each inspection before covering the work. For a project with wetlands, flood exposure, historic-district review or unusual lot conditions, resolve those questions early instead of waiting until the Building Department identifies the missing approval.
