Unincorporated Arapahoe County
Plumber Four Square Mile CO
Four Square Mile is a census-designated place in unincorporated Arapahoe County, pressed against Aurora. It does not have a city building department.
Tank versus tankless at the county
Arapahoe County's residential permit instructions, for unincorporated land, let you file a non-review water heater that is not tankless. The county says that permit is issued when you pay. A tankless water heater is filed as a residential remodel. You attach a gas-pipe isometric and the manufacturer's instructions, and a plans reviewer checks the application before it is issued. The county's page also says its 2021 code criteria took effect April 1, 2022, and that the website was being updated. Confirm the current code before you rely on an old detail sheet. This is not Aurora's same-day inspection program, and it is not Denver's quick permit.
You are not in Aurora or in Denver's Cherry Creek
This place is a census area, not a city. Aurora Water's tap rule applies to Aurora Water customers, not to every nearby ZIP. Denver's lateral rule applies in Denver. If the parcel is unincorporated Arapahoe County, the county is the building department. Water and sewer may be a district. The county instructions for a bedroom addition on a septic system ask for a certificate of sewer availability. Ask which system you have before you camera the wrong pipe.
Questions to settle first
Is a tankless heater a simple permit in Four Square Mile?
Not if the parcel is unincorporated Arapahoe County. The county files a non-tankless water heater as a non-review permit issued on payment. Tankless is a remodel: gas-pipe isometric, manufacturer instructions, and a reviewer before issuance. Confirm the parcel is actually in the county, not in Aurora or Denver.
Is Four Square Mile the same as a Denver neighborhood?
No. This is a census-designated place with its own geography. Denver's Cherry Creek neighborhood is inside Denver and uses Denver's permits. Aurora is a third jurisdiction. The mailing city on a letter does not decide. The parcel does. Ask them to write that limit into the quote before you compare it with another company.
Who owns the sewer lateral?
Not answered by the county's heater instructions. A district, a city, or a septic system may serve the lot. Do not borrow Aurora's tap rule. Get the provider from the bill or the county's sewer-availability step if you are adding a bedroom on septic.
A slow drain is drain cleaning until a camera shows a broken sewer line. A tank swap is water heater replacement. Confirm the permit office and the utility for this address before the work is closed up.
