Before installing a solar water heating system, you should investigate local building codes, zoning ordinances, and subdivision covenants, as well as any special regulations pertaining to the site. You will probably need a building permit to install a solar energy system onto an existing building.
The matter of building code and zoning compliance for a solar system installation is typically a local issue. Even if a statewide building code is in effect, it's usually enforced locally by your city, county, or parish.
Common problems homeowners have encountered with building codes include the following:
- Exceeding roof load
- Unacceptable heat exchangers
- Improper wiring
- Unlawful tampering with potable water supplies.
Potential zoning issues include the following:
- Obstructing sideyards
- Erecting unlawful protrusions on roofs
- Siting the system too close to streets or lot boundaries.
Special area regulations -- such as local community, subdivision, or homeowner's association covenants -- also demand compliance. These covenants, historic district regulations, and flood-plain provisions can easily be overlooked.
To find out what's needed for local compliance, contact the following:
- Your local jurisdiction's zoning and building enforcement divisions
- Briefly describe your intended construction, asking for other relevant ordinances/codes that might be in effect.
- Find out if there are any additional local amendments or modifications to the regulations in effect.
- Ask how to determine whether you are located in a historic district, flood-plain area, or any other special category regulated by a government body.
- Ask where you may find pertinent ordinances/codes (local library, government office, etc.).
- Read pertinent sections of the regulations, making photocopies of information you wish to file for future review and design/installation analysis.
- Homeowner's, subdivision, neighborhood, and/or community association(s)
- Ask if they have any ordinances, provisions, or covenants that may affect the design and installation of the system.
- Copy and file pertinent sections for reference.
