Madison, Connecticut Building Permit Guide

The Madison Building Department at the Town Campus, 8 Campus Drive, reviews plans, issues building and trade permits and inspects the work, with applications filed through the town’s OpenGov online permit center. Most home projects need the Health Department’s approval before the building application, zoning review now happens inside the building permit, and the fee works out at about $13.26 per $1,000 of value, education fee included, with a $25.26 minimum.

What requires a building permit in Madison?

Madison’s rule is broad: building permits are required for all construction except a homeowner’s replacement of small sections of non-critical existing structures. The department gives two examples. Replacing a window sash needs no permit, but replacing the whole window does; replacing a few damaged pieces of siding needs no permit, but re-siding a sizable part of a house does. The town’s permit pages walk through new homes, additions, decks, accessory buildings, pools and hot tubs, and generators.

What the town decides and what the state holds

The building code is the State Building Code, and the department enforces the 2022 edition. Madison decides the rest through Chapter 6 of its code (adopted September 12, 2016) and its land use rules: permit fees, the reinspection and late-certificate charges, contractor construction hours, and a 90-day demolition delay for older buildings. The Planning and Zoning Commission’s regulations set a 50-foot setback from critical coastal resource areas and coastal site plan review, the Health Department signs every residential building permit, and the town’s Floodplain Management Ordinance, approved June 26, 2023, governs flood zones.

Madison building department: who handles permitting

John Cochrane is Madison’s Building Official. Each application circulates to the offices its scope touches: the Wetlands Official (who also reviews erosion and stormwater controls), the Health Department, Engineering for flood zones, the Zoning Officer and the Building Official, plus the Fire Marshal on commercial work. Once every office has approved and the fees are paid, the Building Department makes its final review and issues the permit.

Madison permit types and application documents

Every building application carries the contractor’s license and a certificate of liability insurance with workers’ compensation cover, plus detailed, code-compliant construction plans; the department will not accept one-line drawings or sketches. An owner who authorizes someone else to apply uses the town’s owner letter of authorization, and the state workers’ compensation waiver form (7B) is posted with the permit links. Zoning approval is now part of the building application, so a site plan or A-2 survey showing distances to the property lines goes in with it.

Residential permits

New home: Health Department approval of a septic plan review first (and a B100a application for a teardown rebuild), then code-compliant plans in one PDF set and one paper set delivered to the department, the energy compliance report (REScheck), beam information, braced wall calculations, mechanical drawings and, if subcontractor costs are included in the value, a breakdown of them. Addition, deck or accessory building of 200 sq ft or more: a B100a approval from the Health Department, with a site plan showing the distance to the septic system and well, then existing and proposed floor plans. Pool or hot tub: B100a approval of the location; for an in-ground pool a stamped engineered plan less than two years old, a barrier plan and the alarm details; for an above-ground pool or hot tub the specification sheets; a separate electrical permit in every case. Generator: an electrical permit with a site plan showing the exhaust direction, at least 18 inches from the house and 5 feet from any opening, the fuel source and piping, and a load calculation; a B100a is needed if it sits more than 10 feet from the house.

Commercial permits

Commercial applications follow the same workflow with the Fire Marshal added, who reviews plans for compliance with the Connecticut Fire Safety Code. A commercial certificate of approval costs $50, and the Fire Marshal can also charge a $50 reinspection fee when a fire code violation has to be rechecked. Site plans and special exceptions go to the Planning and Zoning Commission; the land use fee ordinance charges $150 plus $5 per 100 sq ft of non-residential space, up to $3,000.

For tenant improvements and new commercial builds, Alliance handles commercial permit filing through issuance. More on this: commercial building permits explained.

What comes before the building permit

• Health Department: every residential building permit is reviewed and signed by the Health Department. Projects that increase potential water use or lot coverage must show room and soil for a code-compliant septic system, sometimes through deep test pits or an engineer’s design.
• Wetlands: the Wetlands Official reviews the application and its erosion and stormwater controls.
• Coastal: a coastal site plan where the work is in the coastal zone and not exempt (see below).
• Flood zones: Engineering reviews work in a special flood hazard area under the floodplain ordinance.
• Seasonal cottages: under the Winterization Ordinance, an engineered, code-compliant septic system must be designed, approved and installed before a building permit for year-round conversion.

Madison permit costs and fees

Two official versions of the building fee are posted, and they price a job slightly differently. The Building Department’s permitting page shows the fees approved by the Board of Selectmen for July 1, 2016: $25 for the first $1,000 of valuation, $13 for each further $1,000 and 26 cents per $1,000 for the state education fee. Chapter 6 of the Town Code, adopted later on September 12, 2016, sets $13.26 per $1,000 of estimated cost or fraction, with a $25.26 minimum, for building, electrical, gas, mechanical and plumbing permits alike; its 26 cents matches the education fee.

On a $30,000 project, the department page’s method gives $25 plus 29 × $13 plus $7.80, or $409.80; the Town Code rate gives 30 × $13.26, or $397.80. The page’s own examples are $25.26 for a $1,000 job and $38.52 for $2,000. The Code text is the adopted ordinance, but the page is what the office posts, so ask which method it bills. The permitting page says fees are payable by check to the Town of Madison when you apply. Town government buildings pay no permit fees.

Trade permits and who may pull them in Madison

Electrical, gas and propane, mechanical and plumbing work each have their own permit under the Town Code, priced on the same per-$1,000 basis as the building permit, and a subcontractor whose work is covered by the general contractor’s fee pays a $15 handling fee. Pools, hot tubs and generators all need electrical permits, and a septic installation or repair needs a separate septic permit from the Health Department, done by a licensed installer.

Madison requires licensed contractors to pull permits for any work they perform, and stresses that the building code is the same for contractors and homeowners. A homeowner’s own small repairs to non-critical parts of a house need no permit. Trade licenses and home improvement and new home construction registrations come from the state Department of Consumer Protection.

How to apply for a Madison building permit

Review, corrections and what causes delay

State law gives the building official 30 days from the date of application to issue or refuse a permit. Madison’s preferred channel is its OpenGov permit center; state law also lets an applicant file in person, by mail or by email in the manner the building official sets, so call the office if you cannot use the portal. The department warns that complex projects can take several weeks to clear every office. Septic review can add time: a project that adds water use or lot coverage may need soil testing, an engineered design or groundwater monitoring, which can only be done in the spring, before the Health Department will sign, and on small lots with high groundwater or shallow ledge a permit may not be approvable. One-line drawings and sketches are not accepted.

Madison inspections and closeout

The person who signed the permit application is responsible for calling for inspections, at least two days ahead; there are no same-day inspections, and the owner or agent must be present. For a new home the town’s list runs from footings with forms and reinforcement in place, foundation wall rebar with concrete delivery slips, waterproofing with footing and curtain drains to daylight, and a 10-mil slab vapor barrier, through floor framing anchors, framing with window and door pans, roof ice-and-water and sheathing seam sealing, the air barrier, trenches, rough heating and air conditioning, a duct blast and blower door test witnessed by the Building Official, rough plumbing and electrical, insulation once the exterior is weather-tight, and permanent electrical service, to the final.

The final inspection leads to a certificate of occupancy for habitable space or a certificate of approval for other work, which the Building Official signs once zoning compliance is confirmed, on average in five to seven days. House numbers 4 inches high must be on the mailbox and the house at the final. Construction may run from 7 a.m. to 6 p.m. on weekdays from April to October, sunrise to sunset on weekdays from November to March, and 8 a.m. to 1 p.m. on Saturdays, never on Sundays.

Connecticut building code

Madison enforces the 2022 Connecticut State Building Code, in force since October 1, 2022: the 2021 international codes with the state’s amendments, the 2020 National Electrical Code and ICC A117.1-2017. The 2026 edition is delayed; once it takes effect, the filing date will decide which edition applies.

Connecticut has one State Building Code: the code itself sets which work needs a permit and which is exempt, every town’s building official is licensed by the State Building Inspector, and there is no county government. Connecticut rules

Coastal site plan review, setbacks and flood rules in Madison

Section 15.2 of the zoning regulations requires coastal site plan review for changes to buildings, uses and structures in the coastal zone unless exempt, and no such work may start until the plan is approved. Minor additions, interior work, and residential walks, terraces, driveways, decks, pools, docks and accessory buildings up to 200 sq ft are exempt unless they come within 25 feet of tidal wetlands, beaches and dunes, coastal bluffs and escarpments or coastal waters (or, for the residential structures, affect public beach access or need substantial regrading or fill); a conforming single-family house is exempt unless it is within 100 feet of those resources or on an island without vehicle access. Separately, the regulations keep all buildings 50 feet from critical coastal resource areas, except accessory buildings with footprints up to 200 sq ft, additions that do not change the footprint and uncovered decks. Engineering administers the Floodplain Management Ordinance approved June 26, 2023, which requires a floodplain development permit before any development in a special flood hazard area.

Madison building permit FAQ

How much is a building permit in Madison?

About $13.26 per $1,000 of value with the state education fee, and at least $25.26. On a $30,000 job the two posted methods give $397.80 (Town Code) or $409.80 (department page).

Do I need a separate zoning permit?

No for building projects: zoning approval now sits inside the building permit application, so include a site plan. Some accessory buildings under 200 sq ft need an administrative zoning permit.

Why does the Health Department have to sign my permit?

Every residential building permit is reviewed by the Health Department, which checks that a code-compliant septic system could still fit if the project adds water use or lot coverage.

How do I book an inspection?

Call 203-245-5618 at least two days ahead. There are no same-day inspections.

Can I tear down an old house right away?

Not if it is 500 sq ft or larger and more than 60 years old: notices go out within 5 days and a 90-day waiting period follows, with objections allowed for 45 days.

What does a late certificate cost?

$200 if a certificate of occupancy is requested a year or more after the final inspection, or a certificate of approval is not obtained within a year of completion.
