​UDC Permit Tabulation (By County)​​

Act 211 requires the section to accept a standard electronic edifice permit form (SBD-5823) available to municipalities by January 2, 2017. This permit form shall crave contractor license numbers and the expiration dates of their licenses. It also requires municipalities or their agents to provide their permit forms electronically to DSPS through our approved electronic system by January ii, 2018. These permits must exist submitted to DSPS by the 15th of the first month later it is issued. If a municipality fails to submit the permit by the required time after the permit was issued, a refund of the amount paid for the building let minus the land seal shall be given to the permit applicant.

To ensure compliance with Human activity 211, municipalities must contact DSPS UDC staff to obtain an access code and choose the method by which they will submit information to the DSPS. All municipalities must begin supplying their new 1- and two- family domicile allow information to the DSPS by January 2, 2018.

An official representative of the municipality should initiate and authorize the creation of the municipality's access code and selection of the filing method. A building inspector contracted with the municipality may establish a login access code with this organization only upon completion of the Act 211 Inspector-Muni Agreement betwixt the inspector and the municipality. Maintain a copy of the agreement for your records. There is no demand to submit the agreement to the section.

Municipalities

DSPS is offer three ways to electronically submit these permits:

1. Applicants file permits electronically to the municipality through the DSPS system, and the municipality reviews the permits online through the same DSPS arrangement. Let information is automatically provided to DSPS.
2. A municipality may utilise the CSV template file, provided by DSPS, to enter all allow information. The CSV file must be manually uploaded to the arrangement each month and is then available in the electronic system.
3. Municipalities that incorporate their own computerized permit filing system may interface with the Department'due south information connector software. See DSPS Edifice Allow Organization Application Programming Interface (API) for more than information on implementing this choice.
   

​The Municipality Workspace provides the municipal representative access to permit information submitted by builders of for new one- and ii- family dwellings. Municipality FAQ

Municipal building permits for new one- and ii- family dwellings that differ from the one on the DSPS website may not be utilized until approved by the section.

Permit Pullers

Permit pullers​ must submit all required plans and data directly to the municipality per municipality'due south instructions. The plans, data and permit must exist reviewed, and the approved permit fee must be paid before the permit is considered an issued permit.

To file a building permit for a new one- and two- family dwelling house, contact the municipality directly to determine how edifice permit applications should be filed.

FAQs

Deck Codes SPS 321.225

Can we still use the UDC deck codes that we accept always been using or is Appendix B the new lawmaking we have to enforce? How does Appendix C bear upon decks?

The department has determined that a deck tin can be built per the following methods effective January ane, 2016:

• OPTION 1
  SPS 321.225 Decks. (1) Decks attached to dwellings and
  whatever discrete decks that serve an exit shall comply with the applicable
  provisions of subchs. II to X of ch. SPS 321, including all
  of the following:
  (a) Excavation requirements under due south. SPS 321.fourteen;
  (b) Basis requirements under southward. SPS 321.15 (2) (f);
  (c) Frost penetration requirements nether s. SPS 321.16;
  (d) Load requirements nether s. SPS 321.02;
  (east) Stair, handrail and guard requirements of south. SPS 321.04.
  (f) Decay protection requirements of south. SPS 321.ten.
• OPTION 2
  SPS 321.225 (2) A deck that complies with the standards in ch. SPS 320-325 Appendix B, and ch. SPS 320-325 Appendix C, if applicative, shall be considered as complying with sub. (1). Meaning, you would follow Appendix B and C exclusively.
• OPTION 3
  Likewise, the section has determined that a deck designed and constructed to the DCA6 standard, (Prescriptive Residential Deck Structure Guide-2012 IRC version by The American Would Quango), would exist considered code compliant. The decision was based on several factors which included the post-obit:
  -Based on prior analysis by the department, the DCA6 standard met or exceeded Wisconsin Uniform Dwelling Lawmaking requirements.
  -The DCA6 standard is primarily based on NDS standards, which the Department also adopts in SPS 320.24
  -Finally, utilizing the DCA6 standard would in fact be considered a grade of structural assay which is accustomed under the scope of SPS321.02(2).

Notation: Yous may not "mix and lucifer" the options, meaning take parts from Appendix B then use parts of SPS 321.225(1).

Garage Penetrations SPS 321.08

I am inquiring about holes in an attached garage. Is at that place any code that requires the sealing of holes in the garage? We do seal all holes and boxes on the mutual wall but we accept been cited twice for not sealing in the garage.

Yes, holes created in burn separations dwellings and garages must be protected. This includes holes that were drilled for wiring and not used.

SPS 321.08(ane)(a) requires burn separation of dwelling house units from fastened garages.
SPS 321.08(3)(b) specifically addresses penetrations past electrical and plumbing components.

SPS 321.08(three)(b) (b) Electrical and plumbing components. Penetrations of a required separation past electrical and plumbing components shall exist firmly packed with noncombustible fabric or shall be protected with a listed through−penetration firestop system with a rating of at least one 60 minutes.

Habitable Rooms in Basements SPS 321.05(2) & 323.02(3)(c)

I have a question regarding habitable rooms in basements without openable windows. In a rec room or theater room in the basement with no openable windows, SPS323.02 (3) (c) states a balanced mechanical ventilation arrangement producing one air change per hour of fresh outside air while room is occupied must be provided. Does a unproblematic frazzle fan in the basement rec room authorize for this ventilation?

No, you cannot merely exhaust air from the habitable room. There are ii codes that crave fresh outside air be brought in while in utilize for habitable rooms without openable windows. Fenestration air through leakage does not apply towards this. The codes are listed beneath:

SPS 321.05 Natural ventilation.
(ii) VENTILATION. (a) one. Balanced mechanical ventilation may be provided in lieu of openable outside doors, skylights or windows provided the system is capable of providing at to the lowest degree one air change per 60 minutes of fresh exterior air while the room is occupied.

SPS 323.02 (iii) VENTILATION. (c) Habitable rooms.
Habitable rooms without openable windows shall be provided with a balanced mechanical ventilation arrangement producing ane air change per hour of fresh outside air while the room is occupied.

Is the required mechanical ventilation required to exist tied into a light switch so it'south on when the room is occupied?

The fan has to exist tied to a switch that's readily accessible yet the lawmaking is silent as to whether it must be directly tied to a low-cal switch. We practice encourage you to consider the use of an occupancy sensor tied to the ventilation exhaust/makeup air system.

Ramp Footings SPS 321.16

I am looking for clarification on whether or not a ramp requires frost protection for landings that are built into the ramp. When yous read SPS 321.16 (1) information technology states landings shall exist placed below the frost penetration level or least 48" below adjacent course. Do all landings require frost protection?

The lawmaking section below exempts the landings contained within the ramp. If the height of the ramp were to abut a landing or stoop with frost protected footing, then only that finish of the ramp would need to comply. The rest of the ramp does non.

SPS 321.16 Frost protection. (1) EXCEPTIONS.
(d) Subsection (1) (a) does not employ to the footing for a ramp and its handrail posts unless the ramp abuts a frost−protected stoop or landing, in which case only the basis for that abutting end of the ramp is required to take the frost protection under sub. (one) (a), such as past begetting onto the stoop or landing, so that a tripping hazard is non created.

Note: Meet ch. SPS 325 Appendix A for further information.

REScheck

REScheck is a software awarding that has been created by the Federal Department of Free energy for demonstrating compliance with edifice envelope requirements of diverse Land building codes.

Effective January i, 2016, the Wisconsin Uniform Dwelling Code updated its energy conservation code to the 2009 International Energy Conservation Code. As before, compliance with the UDC can be shown by use of the federal REScheck program. However the newest software version available on the federal DOE website no longer has the option to calculate heating plant sizing. In society to go along to offering that service, here is a link to the older version of REScheck, build version four.6.2.0. (This may exist confirmed past looking at "Most" under "Help" on the menu bar of the software. Note that you may accept problems if you have more one version of REScheck on your reckoner). If you utilize this version, you must showtime calculate building envelope compliance past selecting the "2009 IECC" under "Lawmaking" on the menu bar, even though yous may encounter a warning that your location requires employ of the "Wisconsin 2009" code. After printing that out and without exiting REScheck, you may switch your code to "Wisconsin 2009", enter your canton location and calculate your heating plant size on the Loads tab, as before.

Alternatively to size your heating constitute by hand adding after y'all have calculated building envelope compliance per the 2009 IECC, you would perform the post-obit calculations, ignoring the units of measure:

1. Multiply the value in the "Your UA" field, from the Envelope tab of Rescheck, by the temperature difference for your domicile location, which is seventy minus the value from the Outdoor Design Temperature of SPS 323.02(i) tabular array and map in Appendix A of the UDC (link). (Note that subtracting a minus value is the same as calculation.)
2. Calculate your conditioned building volume by multiplying your total conditioned floor area including basements in foursquare feet by its average ceiling height in feet.
3. Select an air infiltration charge per unit between 0.ii and 0.5 air changes per hr, based on your estimated dwelling envelope tightness.
4. Multiply the building volume value from stride two by your selected air infiltration rate from step 3 and by your temperature deviation and by the constant 0.018.

Add together the values from steps 1 and 4 to obtain your minimum heating plant output capacity, in BTU/hour. (Note that the UDC no longer has an over-sizing limit.)
