Site Plan Review in Massachusetts

Site plan review is a local process for reviewing how a project is laid out on its site: access and circulation, parking, drainage, landscaping, lighting, and similar impacts. Most Massachusetts communities require it for larger projects, and many apply it to a wider range of projects than you might expect.

How it differs from a special permit

When site plan review applies to a use that’s allowed by right, it’s generally a process for regulating how the project is built, not whether it can be built. Massachusetts courts have held that, for by-right uses, a board can impose reasonable conditions but generally can’t deny the project outright, except in limited circumstances.

When site plan review is tied to a special permit, the board has more discretion, because the special permit itself is discretionary.

Why it varies so much

Unlike special permits and variances, site plan review isn’t defined in the state Zoning Act. Each community writes its own: what triggers it, which board conducts it, what standards apply, and whether there’s a public hearing. Some communities offer staff-level administrative review for smaller projects. Others send everything to the Planning Board.

Proposed state legislation would change this. See Site Plan Review Reform.

Keeping it on schedule

• Find the trigger. Confirm early whether your project requires site plan review and at what level.
• Read the standards, including any regulations adopted outside the bylaw.
• Expect peer review. Larger projects are often reviewed by consultants hired at the applicant’s expense.
• Coordinate with other boards. Conservation, health, and DPW comments often shape the final plan.
