Frequently Asked Questions

Zoning regulations vary by municipality in both states but generally control how land can be used, the type and size of structures allowed, setbacks, height limits, parking, signage, and special permit requirements. Residential and commercial projects must comply with local zoning ordinances, planning board regulations, and any overlay districts such as historic, floodplain, or coastal zones. Early zoning review is essential to determine whether a project is permitted by right, requires a special permit, or needs a zoning variance.

Both states adopt versions of the International Building Code (IBC), International Residential Code (IRC), and International Energy Conservation Code (IECC), but each applies its own amendments and enforcement procedures. Massachusetts uses the 780 CMR State Building Code with more extensive state-level amendments and stricter energy code requirements in many communities under the Stretch Code. Rhode Island adopts its own state-amended codes with different requirements for fire separation, energy compliance, and permitting processes. The permitting structure, inspection processes, and state vs. local authority also differ between the two states.

Massachusetts now allows ADUs statewide, but each municipality sets its own rules for size limits, lot requirements, owner-occupancy, parking, and whether ADUs are allowed by right or require a special permit. Rhode Island also allows ADUs, with statewide provisions supporting in-law units and expanded housing options; however, each city or town may impose additional zoning, design standards, and permitting requirements. In both states, ADUs must meet building, fire, and energy code requirements and comply with local zoning ordinances.

Strong safety performance starts with leadership setting safety as a top priority. Crews should receive regular training, daily safety briefings, and clear instructions on identifying and reporting hazards. Consistent site inspections, proper use of PPE, and monitoring high-risk activities—like fall protection, electrical work, and heavy equipment operations—help prevent accidents, improve productivity, and reduce delays.

Massachusetts uses a tiered energy-code system. Requirements vary by municipality depending on whether they have adopted the Base Code, Stretch Code, or Specialized Opt-in Code. This can affect insulation values, mechanical system choices, solar readiness, and overall project cost.
Rhode Island uses a single statewide energy code, by adopting the 2024 IECC, which increases efficiency requirements for all projects. Builders must plan for tighter building envelopes, electric-ready infrastructure, and updated testing standards.
Overall, Massachusetts requires location-specific planning, while Rhode Island provides consistent statewide expectations. Both states aim for higher performance and lower long-term energy use.

A thorough plan review identifies code issues early, allowing design corrections before the project reaches the permitting stage. This prevents permit delays, costly redesigns, and construction-phase corrections. Reviewing plans up front ensures the project meets structural, life-safety, energy, zoning, accessibility, and mechanical code requirements—resulting in faster approvals and a smoother building process.

Internal inspections allow builders to verify that each phase of work matches the plans, specifications, and code requirements. Catching issues early reduces rework, keeps the project on schedule, and minimizes the risk of failing a municipal inspection. Regular quality-control checks also ensure that materials, installations, and workmanship remain consistent and compliant from start to finish.
