HISTORIC SAN FRANCISCO AND ROOFTOP SOLAR

Historic Home Renovation

If you own an older home or are in the market for a taste of yesteryear, The City of San Francisco has developed many programs to help encourage the restoration of historic homes and districts and offers programs and resources to encourage property owners to restore or rehabilitate historic properties.

  • The Mills Act  - is a state law that encourages the preservation of historic homes by offering a tax assessment at a lower tax rate.
  • Preservation Easements – Property owners, can gain significant tax savings by adding a preservation easement to their historic building.
  • California Historical Building Code (CHBC) –The CHBC provides an alternative building code for the preservation or rehabilitation of buildings designated as "historic.

The Roofs of Historic Homes  

One of the essential aspects of renovating or upgrading a home is maintaining the design and construction of the roof.  The roof defines a building's era and is consistent with a historic district's architecture. The shape and pitch, the size, and the materials used all point to the time in which they were built.

Whether your roof needs replacement or you are renovating a historic home, we have built our reputation on roofs done right.

Solar Power for Historic Homes

There are many options for integrating solar with older homes and preserving their architectural character, whether your home is new, vintage, or historical. Preserving history is an integral part of the future of San Francisco. 

Also, while it is important to preserve history and maintain the premises in their historical context, installing solar power is a viable addition to any building.  So how do we address the preservation of the historic home while upgrading to cost-effective solar energy?
