Background
#A building permit for PV in Uri is not normally required: suitably adapted roof systems in building and agricultural zones are notified to the municipal building authority under Art. 18a RPG and Art. 32a RPV.
On pitched roofs, the system may project no more than 20 cm, while flat roofs have a 1 m limit plus the 45-degree visibility test. Protected objects, core or townscape protection zones, and systems outside building and agricultural zones instead lead to a building application. Canton Uri’s online form uses the system type and location to indicate whether an application is required.
For ordinary applications, the Coordination Office for Building Submissions states a cantonal review normally within four weeks and an average of two months including the municipality.

What applies in the canton of Uri
#Sufficient adaptation determines the standard route. Under Art. 32a para. 1 RPV, a pitched-roof system may project no more than 20 cm perpendicular to the roof, may not extend beyond the roof when viewed from above, and must be low-reflection and compact. If one requirement is missing, notification is not automatically sufficient.
Flat roofs use different reference points. Art. 32a para. 1bis RPV limits the height to no more than 1 m above the upper edge of the roof rim; the setback must also prevent visibility from below at 45 degrees, and the system must be low-reflection and compact.
Protected status can exclude the notification route. Uri’s guidance names core zones, townscape protection zones, other protected zones, protected cultural and natural monuments, and ISOS areas with preservation objective A. For cultural and natural monuments of cantonal or national importance, Art. 18a para. 3 RPG always requires a building permit.
The zone further limits the case. The Art. 18a RPG standard covers suitably adapted roof systems in building and agricultural zones. For systems outside these zones, Uri’s guidance refers to Art. 32c RPV and the ordinary building permit procedure with a balancing of interests.
The cantonal online form is the first procedural switch. The “Solar system notification” page explains that the system type and location are pre-checked based on correctly answered questions; if a permit is needed, the form directs the applicant to the building application.
The responsible body is clearly identified in an ordinary procedure. Under Art. 100 of Uri’s Planning and Building Act, the building authority decides the procedure; the Coordination Office for Building Submissions states that cantonal review normally takes four weeks and the process including the municipality averages two months.
The process in six steps
#Tick off for your project
Record the site and protection status before requesting a quote
check the building or agricultural zone, core and townscape protection, other protected zones, and cultural and natural monuments using the zoning plan and Uri’s protection inventory. A finding under Art. 18a para. 3 RPG or Art. 32b RPV must be clarified as a possible building-application case before module planning.
Measure the roof type and adaptation
for a pitched roof, document the 20 cm limit, the view from above, low reflectivity and compact arrangement under Art. 32a para. 1 RPV. For a flat roof, include the 1 m roof-rim limit and the 45-degree visibility test in the section drawing.
Prepare the cantonal form completely
the system type and location must match the plans, elevations and photo documentation. For PV, the technical system and its visible integration must be documented so the municipal building authority can assess the Art. 32a RPV criteria.
Send the notification or application to the correct body
in the standard case, notification goes to the municipal building authority; Uri provides the UREC portal for applications and preliminary clarifications. If the online form points to a building application because of protection status, zone or design, the installation plan must not be shortened to a notification.
Plan for the authority’s decision
in an ordinary procedure, the cantonal coordination office normally reviews within four weeks; including the municipal procedure, it states an average of two months. These time indications are planning values from the coordination office, not an individual promise for a specific property.
Implement only after the correct procedure is complete
after notification, the system may be built only within the design accepted by the authority; for a building application, the approved plans govern. Changes to roof type, visibility or location after filing must be clarified again with the municipal building authority.
