DEC REQUEST DS-2014-043 STAFF ANALYSIS

ISSUE: DS-2014-043. Petitioner Donald L. Fuchs Jr., representing the City of Oviedo, seeks a Declaratory Statement on section R101.2 of the Florida Building Code, Residential and the 2008 NEC.

Petitioner seeks clarification of the following question:

Question: Since a townhouse unit is consider a single family dwelling unit with zero lot lines, must each townhouse unit have their own separate utilities including the electric, fire sprinkler system if required, and water/sewer service contain within their own property?

Background:

Petition:

The City of Oviedo has a townhouse project "The Hampton" starting soon. Townhouse are consider single family resident. This project has the electric services and A/C units not attached to the single townhouse but rather a bank of electric services and grouping of the A/C units on common property. They are proposing to install chases with an easement under each dwelling unit though the next unit until the end unit at which time they will be placed outside in a common area of the "building". This "easement" will be under the each unit crossing their property line. These are fee simple townhouse.

The Petitioner respectfully believes the answer is yes to the question outlined above. This type of installation of the electrical service along with the A/C units, water/sewer and fire sprinkler system as proposed would typically be seen in a condo or apartment complex situation but not a single family home. The owners will not have total control of their services and/or equipment since they are not on their property.

Code: Electrical

Section: 230.2, 230.70 (A)1

Florida Building Code

Informal Interpretation

Question: Is it the intent of the electric code to require that each individual townhome in a group of townhomes be served by a separate service and service equipment located on each individual townhome? Conversely, would it be permitted per the electrical code to "bank" the several meters and associated service equipments at the end of each group of townhomes?

Answer:

No to both questions, based on the following commentary.

Commentary:

Townhomes by Florida definition are separate buildings (see Florida statute 481.203(7)),

therefore requiring separate permits and COs and utility services. NEC 230.70(A)(l) and

240.24(B) require the disconnecting means to be readily accessible. If not on the individual

town home, the disconnect could be mounted on someone elses property and not considered readily accessible. Further, the electrical code does not speak to where the service is on a town home, or other structure, merely that it is to be readily accessible. The problem that arises is the fee simple property owner owns the dirt under the unit and the sky above it. The fee simple owner does not own any common property under, over or through another unit. If individual A owns a unit, and desires to dig up the floor to install a sunken living room hot tub, or just because he wants to, he may. This could cut any utility feeds or sewer lines under the slab. The affected party would have no recourse. This is not the same as a condo where the owner only has control of the area inside of the paint, and not the structure. Therefore each unit must have it's own service located on the unit.

Notice: The Building Officials Association of Florida, in cooperation with the Florida Building Commission, the Florida Department of Community Affairs, SBCCI, and industry and professional experts offer interpretations of the Florida Building Codes in the interest of consistency in their application statewide. They are informal, non-binding and subject to

Florida Statutes

553.73 Florida Building Code.—

(2)….Technical provisions to be contained within the Florida Building Code are restricted to requirements related to the types of materials used and construction methods and standards employed in order to meet criteria specified in the Florida Building Code….

(13) The Florida Building Code does not apply to, and no code enforcement action shall be brought with respect to, zoning requirements, land use requirements, and owner specifications or programmatic requirements which do not pertain to and govern the design, construction, erection, alteration, modification, repair, or demolition of public or private buildings, structures, or facilities or to programmatic requirements that do not pertain to enforcement of the Florida Building Code. Additionally, a local code enforcement agency may not administer or enforce the Florida Building Code to prevent the siting of any publicly owned facility, including, but not limited to, correctional facilities, juvenile justice facilities, or state universities, community colleges, or public education facilities, as provided by law.

Staff Analysis: Based on the above facts and circumstances, staff provides the following analysis:

Answer (option #. 1):

Answer (option #. 2): No, as per Section 553.73(2), Florida Statutes, the technical provisions of the Florida Building Code are limited in scope to requirements related to the types of materials used and construction methods and standards employed in order to meet criteria specified in the Florida Building Code. In fact, the Code contains no support for use of a zero lot line/property line as a mean of requiring that a townhouse unit must be provided with its own separate utilities that are contained within its own property. However, in order to meet the intent of section 101.3 of the FBC, Building, it is imperative that each townhouse must have accessible and maintainable independent services as permitted through appropriate legal means.
