Northeast first. Connecticut and New York State now.
We open one state at a time, only where the state's rules let a company that is not an architect or engineer prepare plans for small residential buildings, and only after a licensing attorney has confirmed it in writing. Pick a state on the map for its status.
Status labels are our reading of public rules on the date shown, not legal advice. Your building official decides what is accepted in your town.

Serving now and coming soon
What "serving now" means in Connecticut
One statewide building code (the 2022 Connecticut State Building Code, based on the 2021 International Residential Code) that towns enforce but cannot amend, and published wind and snow values for every town. Detached garages and workshops are our standard unstamped set. Detached ADUs depend on the town: some allow them by right, some opted out of the state's ADU law and wrote their own rules, some do not allow new detached units at all. Shoreline flood-zone lots and Coastal Area Management sites are excluded.
What "serving now" means in New York State
New York City is excluded. Outside it, state law lets a company that is not an architect or engineer prepare plans for a residence of 1,500 sq ft or less (garages not counted), but each building department decides whether to accept unstamped drawings, and the cities we have researched require a licensed professional's stamp. So New York sets are reviewed and sealed by our licensed partner unless your town confirms in writing that it accepts unstamped plans. If you want to ask your town, this is the question: "Will you accept drawings for a detached garage or a one-family ADU of 1,500 sq ft or less that were not prepared by a New York licensed architect or engineer? Please confirm in writing."
What we found in the first six towns
We keep a jurisdiction record for every town we serve: code edition, published design criteria, zoning summary, stamp rules and the submittal list, each fact with its source and date. These summaries are our reading of the published rules on 2026-10-14. Confirm them with the building department before you rely on them.
Stamford
Garages and workshops: our standard unstamped set. Detached ADUs: the city has its own rule, as we read it, allowing one only on a lot over 10,000 sq ft with a single-family house, at most 800 sq ft, and owner-occupied with an affidavit. Our studio and smaller one-bedroom plans fit that cap. The zoning regulations were reorganised in 2025-26, so the Land Use Bureau should confirm the current numbers. Permits through the city's online portal.
New Haven
Garages and workshops: our standard unstamped set. Detached ADUs: the city's current ADU ordinance covers owner-occupied conversions inside existing buildings; new detached ADUs are not allowed under it as of our research date, and the city's own ADU toolkit says so. We will update this page if the next phase of the ordinance passes. No stamp requirement on the city's residential checklists; electronic permitting.
West Hartford
Garages, workshops and ADUs: our standard unstamped set, with the town's published 120 mph wind and 30 psf snow values on the notes sheet. The town's ADU design standards ask for materials and roof shapes that match the main house, so ADU elevations are tailored on the site-adapted tier rather than taken straight from the catalog.
Rochester
The city's new-construction permit packet asks for plans prepared by a New York licensed design professional, so every Rochester set is reviewed and sealed by our licensed partner. Detached garages and sheds in the rear yard are a good fit. A detached ADU is not a listed use in the zoning code in force as of our research date; the city's zoning rewrite would change that, so ask us before planning one.
Albany
The city treats a detached garage or ADU as a new structure that needs a licensed professional's stamp, so Albany sets are reviewed and sealed by our licensed partner. The city has its own ADU rules with a size cap (800 sq ft as we read them) and an owner-occupancy form, and publishes 50 psf snow, 110 mph wind and 48 in frost. Photos of the site are part of the application.
Kingston
ADUs are allowed by right in every zone, attached or detached, and the city offers its own pre-approved small ADU plan. The permit checklist requires drawings stamped by a New York licensed design professional for projects of $20,000 or more, so every Kingston set is reviewed and sealed by our licensed partner. The city publishes its own design values (40 psf snow, 115 mph wind, 48 in frost), which the set reproduces.
Next towns on our list: Norwalk, Fairfield, Danbury, Hamden and Glastonbury in Connecticut; the Buffalo suburbs, Syracuse, Saratoga Springs, Poughkeepsie and Westchester towns in New York. Tell us your town on the waitlist form and we will research it when we open it.
Coming soon
Massachusetts, New Hampshire, Vermont and Maine. Join the waitlist and we will email you when we open your state. Snow-belt and coastal sites in these states will use the licensed-review lane.
Licensed-review sets by request
In states where every set needs a licensed seal we can prepare a set for review and seal by a licensed partner, by request and by quote, once we have a partner licensed there.
Catalog plans anywhere
The PDF and CAD tiers are design documents you can buy from any state, for adaptation by your local professionals. They are not site-specific and not sealed; see the plan licence.
