Committee recommends council adopt residential reach‑code updates, highlights cost‑effectiveness limits

A town climate committee voted to recommend that the town council adopt the updated residential reach code and an accompanying flexible compliance table, after staff explained why certain energy measures are included or excluded from the target‑score calculation. The recommendation passed with five votes in favor and one abstention.

The recommendation matters because the reach code changes set how homeowners must demonstrate energy performance when they remodel and because state rules require energy‑code modifications to be cost effective. Phoebe, a town staff member presenting the item, told the committee that insulation upgrades are generally not cost effective in the newest vintage of houses built to modern standards, so the reach‑code targets rely instead on a “water‑heating package” as the baseline compliance path for that vintage.

Phoebe said appliance replacements can be cost effective but “only at the time of replacement,” and therefore cannot be assumed across the housing stock when setting a universal target score. She added that the flexible compliance approach lets homeowners choose the lowest‑cost measures appropriate to each house. “The energy savings still bear out, but it would be up to the homeowner to decide which measures they wanted to use to comply,” she said.

The staff presentation summarized other clarifications the committee asked for at a prior meeting: low‑income exemptions, the role of the building official in granting waivers, how the statewide analysis is updated, and project cost context. Under the proposed exemptions, homeowners enrolled in PG&E or MCE bill‑discount programs (CARE or FERA) could comply by installing LED lighting and the water‑heating package without meeting the target score.

On code timing and updates, staff said the statewide cost‑effectiveness analysis is prepared by the local energy codes team and is normally aligned to a three‑year code cycle for adoption. Building‑code changes must be approved by council over two hearings: staff expects a first public hearing and first reading on Oct. 7 and a second hearing and possible adoption on Oct. 21, with the ordinance and the building‑code update slated to take effect on Jan. 1, 2026. Phoebe noted the abrupt ending of a solar tax credit could prompt updates before the next cycle, but most work follows the three‑year cadence.

The presentation included compliance‑cost examples developed by the local energy codes team. Staff said those cost estimates use a project cost baseline of about $400 per square foot plus fixed appliance allowances for kitchen and bathroom work and show that compliance costs are generally a modest percentage of a typical remodel. For the newest vintage, staff said most homeowners are likely to choose the water‑heating package, which the local analysis shows as the least expensive compliance method (staff noted the table lists roughly a $150 incremental cost for that package).

Committee members asked for further clarifications. Elsa, a committee member, asked whether the water‑heating package is the only measure that can be used to set the target score; Phoebe confirmed that for the newest vintage the water‑heating package is the baseline option but that other measures may be used by homeowners to meet the target. Olive, another committee member, expressed continued concern about how square footage is calculated, the limited credit for partial prior improvements (for example, partial wall insulation), and whether a 30‑year life‑cycle payback aligns with typical homeowner tenure.

Phoebe described a built‑in waiver pathway: the building official may waive or change the target where unique technical or economic conditions make the measures inappropriate, and the local energy codes team has provided a worksheet to guide that judgment.

After discussion, an unnamed committee member moved to recommend the updated reach code as written (the redlined resolution in the agenda packet with the staff updates to the flexible compliance table); another unnamed member seconded. The committee voted five in favor, with one abstention, to forward the recommendation to council for the Oct. 7 first reading.

The reach‑code conversation included multiple procedural and technical caveats: the cost‑effectiveness analysis informing the targets is statewide work rather than town‑specific; the analysis may be updated early if market or tax‑credit conditions change; and compliance‑cost figures are estimates intended to be conservative. Staff also said they maintain outreach materials and will direct residents to rebates and other programs at the permit counter.

The committee’s recommendation will be included in the staff report to council; council action would be needed to adopt the ordinance and set the effective date.
