Flat ground with almost no elevation change, which is exactly where decks pond.
Flat ground is harder on a deck than sloped ground, because nothing about the site is helping water leave. Santa Ana is built on flat, low lying plains with very little change in elevation, with the mostly channelized Santa Ana River running through the west end of the city. If the surface itself does not carry water off, it stands, and standing water gets through details that a draining deck would never have troubled.
So the first thing we assess here is fall. A deck that ponds needs its slope corrected, not another coat over the top, because recoating a ponding deck just restarts the same countdown.
The city has 79,181 housing units, 96.8 percent occupied, with 54.4 percent of the occupied ones rented. That is heavy multifamily volume: shared walkways, open stairs and stacked balconies that stay in use throughout the repair.
The river is channelized and largely seasonal because of the Prado and Seven Oaks dams, and it has caused severe flooding in the past. That history is a reminder rather than a daily concern for a balcony, but it does frame how the city thinks about drainage, and it is worth knowing where a ground level deck or walkway discharges.
On multifamily property the surfaces that matter most are the ones people use. A stair that is the only route to a second floor door, a walkway serving six units, a landing outside a front door. Those need a traffic rated and slip resistant build, and they need phasing so nobody is cut off while the work runs.

Often, yes. Santa Ana issues Same Day Express Permits for residential and commercial projects that do not require plan check. Work that does need plan check goes through the normal review.
It is common and it is not acceptable. On flat ground the deck has to create all of its own fall, and once that is gone the water sits over every seam and crack for days. Correcting the slope is the repair. A new topcoat over a pond does nothing.
Yes. On occupied buildings we phase the work so every unit keeps a route to a stair, barricade only the section open at the time, and schedule the stages that need cure time around when people need access.
A professionally installed waterproofing system typically lasts many years. Capital Deck & Stair backs most projects with an 8-year warranty on workmanship, and proper maintenance can extend the life well beyond that.
Cost depends on the surface size, condition, and the coating system required. We provide a clear, itemized quote after a free on-site inspection, with no obligation and no pressure.
