Alamo Heights (78209) is a separate city of 1.9 square miles inside Loop 410, incorporated June 20, 1922, the second-oldest municipality in Bexar County. Its Community Development Services desk permits fences, arbors, trellises, decks and patio covers, counts every roofed structure toward lot coverage and impervious cover, and protects heritage live oaks, pecans and cedar elms at 24 inches. Klema Builders files the permit, the worksheet and the tree plan, then builds fixed-price.

## Building in Alamo Heights

- **ZIP and place** (78209): A separate city along Broadway inside Loop 410, north of downtown. Incorporated June 20, 1922 after a 289-to-8 vote, the second-oldest municipality in Bexar County, about 1.9 square miles, fully surrounded by San Antonio, Terrell Hills and Olmos Park.
- **Permit desk** (Community Development Services): The city permits fences, arbors, trellises, walls, retaining walls and wooden decks, plus porch and patio covers, awnings and carports, through My Government Online. The application carries a survey or site plan, the trunk diameter of any tree over 8 inches to be removed, engineered details for any wall or fence over 4 feet, and an impervious-cover worksheet; roofed patios, arbors and gazebos count toward lot coverage, except an entry arbor under 50 square feet and 8 feet tall. New impervious surface carries a stormwater fee.
- **Fence rules** (Code Secs. 3-81 to 3-83): Typically 3 feet in the minimum required front yard, 6 feet in the rest of the front yard, and 6 feet on side and rear lines, measured from the lower side. Accessory buildings sit at least 3 feet off side and rear lines.
- **Design review** (Architectural Review Board): The ARB meets the third Tuesday and is advisory; it reviews demolition cases and the compatibility of new houses and additions, plus commercial and multifamily work. Fences, pergolas and patio covers are staff permits, not board cases. Variances go to the Board of Adjustment.
- **Trees** (Heritage tree ordinance): Live oaks, pecans and cedar elms are heritage trees at 24 inches in trunk diameter. Inside the critical root zone no more than half the area may be paved, no more than 30 percent trenched, and nothing goes within 3 feet of the trunk. Removing a healthy heritage tree requires inch-for-inch mitigation or a fee in lieu. Post and pier layouts are drawn to the root zones first.
- **Ground**: The city plan describes land broken by ridges and drainage courses, with the high ground along Broadway sloping west to the Olmos Basin; streets follow the drainages. Austin Chalk lies near the surface, the same rock the Cementville quarry worked from 1908 to 1985, with clay pockets in between. Piers are sized to which of the two a lot sits on.
- **Lots and homes**: Built out mostly from the 1920s through the 1960s on established lots with detached garages, alleys in places, and a mature canopy of live oaks, pecans and cedar elms. Outdoor projects here work around trees, older foundations and the lot-coverage cap rather than slope.

## Why Alamo Heights is different

Alamo Heights has run its own permit desk since 1922 and writes rules for a built-out city of old trees and established lots: every roofed structure counts toward lot coverage, new hard surface carries a stormwater fee, and the heritage tree ordinance decides where a pier can go. None of it is hard, but a permit filed with San Antonio for an Alamo Heights address is a lost month.

Klema Builders designs pergolas, patio covers and decks to the canopy and the coverage cap, files the permit with the worksheets the city asks for, and writes it into a fixed-price quote after a free in-home consult.

## Questions and answers

### Does Alamo Heights require a permit for a pergola or patio cover?

Yes. The city's permit list names fences, arbors, trellises, wooden decks, porch and patio covers, awnings and carports. A roofed patio, arbor or gazebo also counts toward lot coverage, so the application includes the coverage and impervious-cover worksheet. Klema Builders files the permit through My Government Online with the survey, the tree diameters and the details the city asks for, as a line item in the quote.

### How does the heritage tree ordinance affect a deck or patio?

Live oaks, pecans and cedar elms at 24 inches are protected. Inside the critical root zone no more than half the area can be paved, no more than 30 percent trenched, and nothing is built within 3 feet of the trunk. That is why decks over roots and piers placed between them are the Alamo Heights answer more often than a slab. We map the trees on the site plan before the design is drawn.

### What fence height is allowed in Alamo Heights?

Typically 3 feet in the minimum required front yard, 6 feet in the rest of the front yard and 6 feet on side and rear lines, measured from the lower side of the fence. Any wall or fence over 4 feet needs an engineered detail with the permit. We confirm the section for a corner or double-frontage lot before the quote.

### Will my project go to the Architectural Review Board?

Almost never for a backyard project. The ARB is advisory and reviews demolition cases, the compatibility of new houses and additions, and commercial work. Fences, pergolas, patio covers and decks are staff permits. If a project needs a variance, that goes to the Board of Adjustment, and we prepare that packet too.

### Do you handle the permit and the design review in Alamo Heights?

Yes. In Alamo Heights that means the city permit through Community Development Services with the survey, lot-coverage and impervious-cover worksheets, tree diameters, and engineered details for any wall over 4 feet. We prepare the drawings, the site plan and the material list, file the application, and handle the back-and-forth; the permit and the review are line items in the quote. Every project starts with a free in-home consult and a fixed-price quote line by line within 3 to 5 business days, and we build across San Antonio, the Texas Hill Country and the I-35 corridor to Austin.

### How much does a deck, pergola or covered patio cost in Alamo Heights?

A 16x30 basic wood deck with handrails in Alamo Heights starts at $4,000, labor and materials included. Covered patios, pergolas, composite and multi-level decks are quoted fixed-price, line by line, after a free in-home consult. The written quote arrives within 3 to 5 business days.

### What does it cost to take down an old pergola or deck in Alamo Heights?

A 12x12 pergola removal in Alamo Heights starts at $3,750, haul-away and yard grading included. Decks, patio covers, fences, sheds, hot tubs and playsets are taken down in 1 to 3 business days, hauled off and the ground graded or raked. Concrete footings and any siding or stucco repair at the ledger are handled separately. Already tore it down yourself? We haul off the pile.

### Is taking down an old structure reviewed in Alamo Heights?

A backyard deck, pergola or carport is not a demolition-review case for the ARB, which looks at whole houses and significant structures. Taking one down takes 1 to 3 business days, hauled off and the yard graded or raked, and we confirm with the city desk when a structure is attached to the house or over a heritage root zone before we start.

### How long does a project take in Alamo Heights?

A cedar pergola is built in 1 to 2 weeks on site once materials and approvals are in hand. A composite or cedar deck takes 3 to 6 weeks from signed contract to walk-through once the permit clears, and a multi-level or pool deck 6 to 10 weeks. City permit review in Alamo Heights typically adds 1 to 3 weeks before the build starts. The schedule is committed in writing in the contract.
