Why is home additions different in Central San Diego?

Older homes in San Diego city and La Mesa often sit on lots where additions were built informally over decades, meaning the current structure may include unpermitted work that has to be addressed before a new addition can be permitted and inspected. Hillside lots in this area add structural complexity, with foundations that may need to be carefully tied in to accommodate new loading from an addition above or beside. The payoff is real because adding bedrooms or living space to a well-located central San Diego home almost always returns value in a competitive resale market.
