Brookline Zoning Board upholds inspector, finds lot-line vesting but not right to a duplex

A Brookline Zoning Board of Adjustment (ZBA) meeting reconsidered a rehearing request about whether subdivision-era vesting protects a lot-line adjustment and allows construction of a duplex. After hearing legal arguments and planning staff input, the board voted 5–0 to uphold the building inspector’s denial of permits for a duplex on the lot in question.

The applicant presented two lines of analysis: first, that the relevant 1986–87 subdivision plan (plan no. 19945) and recorded deeds created vested rights under RSA 674:39 that should govern current zoning; and second, that the lot and its existing structure are nonconforming and therefore could lawfully support a two-family dwelling. The applicant’s presenter argued that the deeds and recorded plan entries showed the developer completed the plan’s required actions within months of approval and thus secured the statutory protection.

Planning staff and board members debated what constitutes "substantial completion" under RSA 674:39. Staff noted the standard is scaled to the project and often focuses on tangible on- and off-site improvements (roads, drainage, utilities) but also acknowledged that recording deeds and conjoining lots can be the improvement shown on a subdivision plat in some cases. As a result the board examined the plat notes and the record to identify exactly which improvements were implicated.

During deliberations the board made a series of formal findings. A board member moved and the board found that the plan at issue should be treated as a subdivision recorded in November 1986 and that the relevant improvements to be protected were the plat’s notes 4 and 5 requiring the conjoining of the affected lots. The board then voted that recording of the related deeds constituted substantial completion of the plan for purposes of RSA 674:39 and that rights to those defined improvements vested and are protected from later changes to subdivision regulation, site-plan rules or zoning ordinances.

Despite those findings, the board concluded the vested rights protected only the lot-line changes themselves and did not automatically grant a right to construct a duplex on the reconfigured lot. Members said the lot as it now exists lacks the contiguous dry land area required for a two-family dwelling under the zoning standards applied to building permits. One board member summarized the outcome as: "the improvements are protected, but the lot as presented does not have the required contiguous dry land area for a duplex," and the board therefore had "no basis for overturning the building inspector’s decision." The motion to uphold the inspector’s denial passed 5–0.

Chair (S1) announced that the board’s written decision will be issued in a few days and posted at the town offices; she also explained that anyone directly affected by the decision has 30 days to file a written request for rehearing, which is a prerequisite to appealing to superior court.

The board then covered scheduling for a separate case (case 471) and routine minutes corrections before adjourning.
