Chatham is Cape Cod's most coveted address, and new home construction here is primarily custom, a project that results in a home designed specifically for the site, the client, and the context of the town. The regulatory environment in Chatham is among the most active on the Cape: Conservation Commission review is required for a significant proportion of waterfront and near-waterfront lots given Chatham's extensive Pleasant Bay, Stage Harbor, and Nantucket Sound frontage, and the Chatham Historic District Commission has jurisdiction in the Village Center area. A new home in Chatham needs to be designed and built with all of these factors incorporated from the beginning. For a full regional overview of new construction services, see the New Construction Cape Cod hub page. Herks also builds for clients in Cohasset and Scituate on the South Shore, coastal communities with a similarly active Conservation Commission environment and premium waterfront new construction market.

Frequently Asked Questions About New Construction in Chatham
Why is the Conservation Commission so active in Chatham new construction?
Chatham has more linear feet of water frontage per square mile than almost any other Cape Cod town, Pleasant Bay, Stage Harbor, Nantucket Sound, and the network of ponds and tidal creeks throughout the town all generate resource area buffer zones. The Massachusetts Wetlands Protection Act requires a Notice of Intent before any construction within 100 feet of these resource areas, and the Chatham Conservation Commission enforces this requirement. For Chatham new home construction, the NOI process adds 8 to 12 weeks to the pre-construction timeline and results in an Order of Conditions that governs how the project proceeds. Herks manages this process as part of every Chatham new construction project that requires it.
The specific resource areas that generate Conservation Commission jurisdiction in Chatham include the coastal bank (the top of the bluff above high water), wetlands and vernal pools, bordering vegetated wetlands, and their respective 100-foot buffer zones. Many Chatham lots, particularly in the Pleasant Bay, Stage Harbor, and Nantucket Sound areas, have resource areas close enough to the buildable area that virtually any site disturbance triggers the NOI requirement. The ConsCom Order of Conditions typically specifies construction limits (often marked with orange safety fence), erosion controls, and post-construction stabilization requirements. The NOI process is not a barrier to building, it's a defined regulatory track that Herks navigates for every Chatham project that requires it.
What is the Chatham Historic District Commission and how does it affect new home construction?
The Chatham Historic District Commission reviews proposed exterior changes and new construction visible from public ways within the Chatham Historic District, which covers the Village Center and its immediate surroundings. For a new home within the District boundary, or on a lot whose street-facing elevation is visible from a public way within the District, the HDC reviews the massing, design, materials, and details of the proposed home. The HDC's goal is to ensure new construction is compatible with the historic character of the district. Herks works with the design team and the HDC to develop a project that meets the Commission's standards without compromising the homeowner's program.
The practical HDC process for a Chatham new home: once a design is developed to the schematic level (massing, exterior materials, window and door placement, roof form), the HDC application is filed with the plans and renderings. The HDC holds a public hearing, typically on a monthly meeting schedule, and reviews the submission. If the design is compatible, a Certificate of Appropriateness is issued, which is a prerequisite for the building permit application. If the HDC has concerns, it provides specific feedback and the design is revised. Working with an architect who understands the Chatham Historic District's design vocabulary and the HDC's preferences makes this process more predictable. The HDC timeline needs to be planned into the overall pre-construction schedule, it runs on a monthly cycle and can add 1 to 3 months to the pre-permit track.
What building codes apply to new construction in Chatham?
New home construction in Chatham must comply with the Massachusetts State Building Code, Massachusetts Plumbing and Electrical Codes, the International Energy Conservation Code as adopted by Massachusetts, and local zoning bylaws. The 110-mph design wind zone requirement applies to all structural systems, foundation anchor bolts, framing connections, roof-to-wall connections, and hardware throughout. In FEMA flood zone areas (AE or VE designations on Chatham's waterfront), base flood elevation requirements apply, which may mandate higher first-floor elevations and specific foundation design. Herks and the project's structural engineer incorporate all applicable code requirements from the beginning of the design phase.
The 110-mph wind zone requirement in particular affects framing hardware throughout the structure, it's not just a roof strap requirement, but a full-system requirement that touches the way wall plates are connected to foundations, how roof rafters and trusses connect to wall top plates, how sheathing is fastened, and the hardware at every major framing connection. In Chatham's coastal exposure, this structural specification is especially important because wind loads in exposed waterfront locations can be even more demanding than the code minimum. Herks and the project's structural engineer design to these requirements explicitly, with engineered hardware callouts in the structural plans that are verified during the framing inspection. This is standard practice for Chatham new construction, not an add-on.
How do FEMA flood zones affect new home construction on Chatham's waterfront?
Properties in FEMA AE or VE flood zones in Chatham have additional requirements for new construction. In AE zones (zone with base flood elevation), the lowest floor of the home must be at or above the base flood elevation shown on the FEMA Flood Insurance Rate Map. In VE zones (coastal high-hazard areas with wave action), the requirements are more stringent, elevated structure on pilings or other open foundation, with no enclosed space below the flood protection elevation. These requirements affect foundation design, first-floor elevation, and the usable square footage of the ground floor. Herks identifies flood zone designation at the initial lot assessment and incorporates the requirements into the design from the beginning.
The practical impact on Chatham new construction: AE zone homes often require a crawl space or slab elevation that puts the first finished floor higher than a standard non-flood-zone home, which changes the relationship of the home to the grade and may require steps to the entry. In AE zones, flood vents in foundation walls are typically required to allow water to pass through during flood events rather than accumulate pressure against the walls. VE zone construction on open pilings has a more dramatic visual character, the home is clearly elevated off the ground, and affects how the home is accessed, how mechanical systems are placed, and how the ground level is treated. Flood zone compliance also affects the flood insurance cost of the home, homes built to or above the base flood elevation carry significantly lower National Flood Insurance Program premiums than homes below it.
How long does it take to build a new home in Chatham?
Given Chatham's regulatory environment, the pre-construction timeline is typically longer than in less regulated Cape Cod towns. From initial lot assessment to building permit issuance: 6 to 10 months for a waterfront lot with Conservation Commission and Title 5 requirements. Construction from permit issuance to certificate of occupancy: 8 to 14 months for a custom home. Total project timeline from start to move-in: 14 to 24 months. Herks provides a realistic timeline at the initial project consultation, including the specific pre-construction steps that apply to the lot. For a detailed guide to new construction timelines, see: How Long Does It Take to Build a Custom Home in Massachusetts?
The pre-construction timeline for a Chatham waterfront new home compounds across multiple parallel and sequential tracks: Title 5 septic design and Board of Health approval (which is on the critical path for the building permit application); Conservation Commission NOI filing, public hearing, and Order of Conditions (which takes 8 to 12 weeks from filing and runs in parallel with Title 5 but must be complete before the building permit); HDC review if applicable (monthly meeting cycle, typically 1 to 3 months); structural and architectural design concurrent with these approvals; and the building permit review itself. The construction phase, site work and foundation, framing, exterior envelope, mechanical rough-in, insulation, drywall, finish work, site restoration, and certificate of occupancy, follows. Many Chatham new construction clients also add an ADU (accessory dwelling unit) to the project, the Massachusetts Affordable Homes Act and state ADU regulations affect what's possible; for an overview of the permit process, see: ADU Permit Massachusetts
