Wellesley Zoning Guide

Conforming House Size by Zoning District

Wellesley's TLAG (Total Living Area & Garage) formula determines the maximum buildable square footage on any given lot. The district your teardown sits in directly determines what a builder can construct — and therefore what you can buy. Knowing which zone a site is in before you make an offer is essential.

TLAG = Total Living Area & Garage. The calculation is more nuanced than square footage alone — it factors in finished basement space, garage area, and accessory structures. Always verify with a builder before making assumptions about what can be built on a specific lot. The official Town of Wellesley TLAG worksheet is available at wellesleyma.gov. Our team can walk you through any specific site's buildable envelope before you commit.

How This Tracker Works

Built from the ground up — not scraped from MLS.

Most new construction searches surface the same public inventory every other buyer is already tracking. This map is different. It is built and maintained by Adler Connolly² at MGS Group Real Estate — a team that actively monitors Wellesley's building pipeline through four primary sources, not listing feeds.

📋
Building Permits & Zoning Approvals
We monitor Wellesley's permit portal and ZBA filings to catch teardowns and new builds at the application stage — often months before they list.
🤝
Builder Relationships
Direct relationships with Wellesley's most active spec builders give us early visibility into sites that will never be publicly marketed.
🔍
On-the-Ground Monitoring
Active construction sites are tracked through physical observation, not data feeds — which means we catch things that don't appear in any public record until after a foundation is poured.
📊
Builder History & Quality Analysis
We analyze each builder's prior Wellesley projects for construction quality, material selections, and resale performance — so you know what you're actually buying before a single beam goes up.
Why This Matters
Off-Market Access
Most deals happen before listing
In Wellesley's constrained market, the buyers who access new construction early — through builder relationships and permit monitoring — consistently pay less and get more selection than those waiting for MLS.
Nicole's Construction Eye
We evaluate what others miss
Nicole Connolly's background in luxury construction means we assess structural quality, finish levels, and builder reputation with a depth most agents simply don't have. We've walked hundreds of Wellesley build sites.
Pricing Intelligence
Know what a site is actually worth
Steve's financial background means we model the land cost, construction cost, and exit pricing for every site — so you can evaluate a new construction purchase the way an investor would, not just as a lifestyle decision.
Teri's Network
20+ years of Wellesley builder relationships
Teri Adler has been active in Wellesley real estate for over two decades. Those relationships are the reason this tracker exists — and the reason our buyers see opportunities that others don't.
