ADU Eligibility Quick-Check

An Accessory Dwelling Unit (ADU) is a smaller, independent living unit on the same lot as a single-family home: converted garages, detached cottages, basement or attic conversions, and attached additions all qualify. Most states have streamlined ADU permitting since 2020, but local rules still control size, height, and setback.

Is your lot zoned single-family or multi-family residential?
Does your lot have at least 1,200 sq ft of buildable space?
Is your existing home owner-occupied (in most states this is not required, but some require it for ADU permits)?
Will the ADU stay under your state's size cap (commonly 850-1,200 sq ft for detached)?
Can you provide one off-street parking space (waived in many states within 0.5 mi of transit)?

If you answered 'yes' to most of these, you likely qualify in Maine under recent ADU streamlining laws. The Skowhegan, ME rules below cover local size, height, and setback requirements.

Full Breakdown

Section XII(3) of the Town of Skowhegan Site Plan Review Ordinance covers off-street parking and loading. Subsection A requires adequate off-street parking for all new development and changes of use. Subsection E is the Minimum Off-Street Parking Requirements table, headed USE CATEGORY and MINUMUM REQUIREMENT (spelled that way in the printed ordinance). Under Residential Uses it prints 1 space per dwelling unit for Single-Family Dwelling, Two-Family / Duplex and Multifamily Housing, 0.5 space per dwelling unit or bed for Senior Housing / Nursing Care Facility, and No additional parking required for Accessory Dwelling Unit.

Other parking provisions in the same section shape the figures. Subsection B says, in accordance with Maine law, the municipality shall not require more than two (2) parking spaces per dwelling unit for residential developments containing four (4) or more dwelling units. Subsection C allows parking spaces to be shared between uses with different peak demand periods, subject to Planning Board approval, and Subsection D has the Planning Board reduce the required spaces where shared parking is provided, public parking is within ¼ mile with written authorization from the Municipal Officers, or a parking demand analysis shows fewer spaces will serve the use.

Scope matters. Site plan review reaches multi-unit residential uses: a residential structure containing three (3) or more dwelling units, an increase of three (3) or more units in a structure within any five (5) year period, or conversion of a non-residential structure into three (3) or more dwelling units. Section V separately lists the construction, alteration, or enlargement of a single family or two-family dwelling, including accessory buildings and structures, among the activities that shall not require site plan approval. The term accessory dwelling unit does not appear elsewhere in the ordinance, and the Code Enforcement Officer determines whether an activity is subject to review.

Violations & Fines

The Code Enforcement Officer or an authorized agent enforces the ordinance under Section XXV, notifying the responsible party in writing and ordering corrective action. The Officer can order the discontinuance of illegal uses or work. Violations are enforced under 30-A M.R.S. § 4452, each day after notice is a separate offense, and the Select Board or its agent can enter administrative consent agreements to resolve violations and recover penalties without court action.
