The homes across New Haven County
The Census Bureau no longer publishes Connecticut counties, so the county column below is the total of the town rows. Medians cannot be totaled; for those we show the lowest and highest town.

What it means for a cleaning
Three cities carry most of the county's renting: New Haven with 39,217 renter households, Waterbury with 24,094 and West Haven with 10,348. Leases end, units turn over, and landlords and tenants both need empty-home move-out cleaning.
The old housing is in the cities and the valley. 39.6% of New Haven homes were built before 1940, 34.7% in Ansonia and 30.8% in Waterbury. Homes that age often have tall baseboards, window sashes, radiators and worn wood floors, which take slower work than a newer house in Oxford (median year built 1986) or Beacon Falls (1985).
On the shore, some homes sit empty part of the year. Madison counts 679 seasonal homes (margin ±231), Branford 615 (±211) and Guilford 583 (±183); opening one for the season calls for a deep clean.

Sales tax on cleaning in New Haven County
House cleaning in Connecticut is a taxable janitorial service at 6.35%, the same in every town (Regulations 12-407(2)(i)(Y)-1; General Statutes 12-408). The regulation's definition covers carpet and upholstery cleaning too. It sets out two cases that are not taxed: someone who cleans three or fewer homes a year and is not otherwise in the cleaning business, and a housekeeper you employ directly on a wage. A cleaning company is neither, so its bill carries the tax.
Rental and short-term rental rules in New Haven County towns
Connecticut has let towns license short-term rentals by ordinance since 1 October 2024 (Public Act 24-143). Here is what the town codes say, read 19 September 2026.
| Town | Rule | Code section |
|---|---|---|
| Milford | A permit before listing a short-term rental. Hosted rentals are in the owner's primary residence; unhosted ones need the owner or an agent within 30 miles. Renters get a packet naming trash and recycling locations. | Code Ch. 11, Art. V, ordinance of 8 May 2026, not yet codified |
| Branford | Annual short-term-rental registration; online applications opened 1 March 2026 and permits run 1 May to 30 April. | Short-Term Residential Rental Ordinance, Ch. 199 |
| New Haven | Rental properties of two or more units need a residential rental license after an inspection; owner-occupied parcels of three or fewer units and non-owner-occupied single units are exempt. Tenants must keep units clean and sanitary. We did not find a short-term-rental ordinance in the city's code. | Code Ch. 17, Art. XIV, amended 2 Sep 2025 |
| Wallingford | No unit may be rented without a current certificate of compliance, renewed every five years after inspection, and no vacant unit may be let unless it is clean, sanitary and fit to live in. | Rental Housing Code Ch. 167 (Ord. 662, 10 Jun 2025) |
| Guilford | No short-term-rental chapter in the Town Code; zoning Ch. 273 sets what each district allows. | Town Code on ecode360 |
In Madison, Waterbury, Hamden, Meriden, West Haven, Naugatuck, East Haven, Cheshire, North Haven and the other towns, ask the town before you rent. Wallingford's clean-and-sanitary rule is the plainest case for a turnover clean between tenants. State law gives the landlord 21 days after the tenancy ends, or 15 days after a written forwarding address if later, to return the deposit or itemize deductions (General Statutes 47a-21(d)(2)).

Common questions about house cleaning across New Haven County
Do you do move-out cleaning for tenants and landlords across New Haven County?
Yes, for either side of the lease. We clean the empty unit top to bottom: inside cabinets and closets, appliances, bathrooms, floors and the marks furniture leaves behind. Connecticut requires the landlord to return the deposit or itemize deductions within 21 days of the tenancy ending, so booking the clean before you hand in the keys helps. A clean unit shows its real condition; nobody can promise the deposit comes back.
Is cleaning taxed the same way in every town across New Haven County?
Yes. Connecticut's 6.35% applies statewide with no town or county add-on, so a clean in Madison is taxed exactly like one in Waterbury or Meriden. Carpet and upholstery cleaning is included, which is different from New York, where that work is exempt. The tax goes by where the home is, not where the owner lives or the bill is mailed.
Which towns do you cover across New Haven County?
All 27: Ansonia, Beacon Falls, Bethany, Branford, Cheshire, Derby, East Haven, Guilford, Hamden, Madison, Meriden, Middlebury, Milford, Naugatuck, New Haven, North Branford, North Haven, Orange, Oxford, Prospect, Seymour, Southbury, Wallingford, Waterbury, West Haven, Wolcott and Woodbridge. If your address uses a section name such as Northford or Woodmont, just give us the street and town in the quote form.
When do people book cleanings across New Haven County?
Google Trends for the Hartford and New Haven market shows house-cleaning searches highest in June, July and August and lowest in January, February and December, averaged over 2021 to 2025. Deep-cleaning searches there peak in April. Summer dates fill first, so if you need a clean before a move or a summer guest, ask early.
